Failed attempt to fix AIWA HS-PS303.

Heavy corrosion. The SMD capacitors were very hard to remove (the solder joints were dry, and the pads were easy to break).

I didn’t think I’d need to say this, but apparently I do:

Don’t use the Raspberry Pi 2040 to build a DCC decoder.

It’s not really wrong, of course, and it gives you ridiculous amounts of computing power, but to get that you need miles and miles of extra components. Like a dozen of decoupling capacitors, an external oscillator, and of course an external flash memory. You can maybe do that sort of thing in H0, but for real model trains, it’s just not ideal. Pick something like an ATTiny or STM32C0 (I’ve done both for different projects): Cheap, just one or two decoupling capacitors, no external oscillator required and no external flash memory needed either.

The versions of the RP2350 with built in memory may be a better idea, once they fix the GPIO issues anyway, but still, there’s the oscillator and just way too many capacitors.

(Some of these concerns may be different if you want to add sound support, which requires more memory anyway. But I’d argue that sound in model railroads is a mistake anyway. I’ve never seen an N scale locomotive that sounds good, it’s all just an annoying expensive gimmick.)

Also while we’re at it, don’t use a cheap standard bridge rectifier. The steep slopes of the DCC signal mandate a really fast rectifier, typically Schottky diodes. This is particularly important when you have RailCom on your layout. You may need four individual diodes instead of one rectifier, but since you won’t need all the capacitors of the RP2040, you still win out in the end (it’s also typically smaller than the rather large SMD standard rectifiers).

This is a call-out post for https://github.com/gab-k/RP2040-Decoder . It’s a useful project, but it’s also far from ideal.

Smart Tweezers ST5S vs. Conventional Multimeter: A Smarter Choice

Smart Tweezers ST5S and conventional multimeters are both essential tools for electronic testing and troubleshooting. However, they differ significantly in terms of functionality and ease of use.

Smart Tweezers ST5S:

All-in-One Design: Smart Tweezers combine a set of high-precision SMD probes and a digital multimeter into a single handheld device. This streamlined design simplifies testing and eliminates the need for separate probes and multimeters.

Automatic Component Identification: One of the standout features of Smart Tweezers is their ability to automatically identify and evaluate SMD components. This saves time and reduces the risk of human error. The device can recognize resistors, capacitors, and inductors.

Ergonomic and Portable: Smart Tweezers are easy to handle and operate with one hand. Their lightweight and ergonomic design make them a preferred choice for professionals and hobbyists alike.

Real-Time Measurement: These tweezers provide real-time measurements, allowing users to monitor changes in component values as they troubleshoot. There's no need to disconnect and reconnect probes repeatedly.

LCD Display: Smart Tweezers feature a clear LCD display that shows component values and measurement results. It's easy to read and interpret, even in low-light conditions.

Conventional Multimeter:

Multiple Components: A conventional multimeter typically consists of separate probes and a central unit. It can measure a wide range of electrical parameters, including voltage, current, resistance, capacitance, and more.

Manual Range Selection: Conventional multimeters often require users to manually select the appropriate measurement range and function. This can be time-consuming, especially when testing various components.

Limited SMD Testing: While multimeters are versatile, they are less suitable for testing surface mount devices (SMDs) without the use of additional adapters or fixtures. This can add complexity to SMD troubleshooting.

Complex Readings: Interpreting multimeter readings can be challenging, especially for beginners. Users must understand the correct units, ranges, and measurement modes.

In summary, Smart Tweezers ST5S are a specialized tool tailored for SMD component testing, offering automatic identification and real-time measurements in a compact and user-friendly form. They are ideal for users who frequently work with SMDs. On the other hand, conventional multimeters are versatile devices suitable for a wide range of electrical measurements but may require additional tools for SMD testing.

JP-800000000000000000000

Haha not really, just the JP-8000.

I was surprised to see these things are going for over a grand now. Last time I checked they were half that or less. Why the jump in price? Hmmmm. Anyway this one came from Mercari. The seller described it as functioning but with no output, headphones ok, low battery memory corrupt! message on power up. A wee bit of google sleuthing and I found a fix, so I bought the synth and ordered parts. The low/zero output culprit is this guy.

Capacitor 219. A 16. 22uF SMD weeee little fucker. Screwdriver tip for size comparison. The component is 5mm wide. Here's the mainboard after I removed the bad one.

You can see two solder pads there above the white connector, just below the center of the photo. While desoldering the capacitor, the tell-tale stink of a bad cap wafted up and nearly gagged me. Yuck.

Different angle, with the new one in. I used a 22v 22uF part because I read that the circuit is running at 15v and that's close to tolerance for a 16v cap so there you go. Man was this a bitch to do, my goddam hands are shaky as fuck. While I was at it I thought I'd recap the power supply.

Had to do some creative component placing as I'd ordered 35v versions of everything so the parts were physically much larger than the factory stuff. I did find that the wee one on the right you see there, the 35v version was too fat and stout so it wouldn't fit in there with the two tilted over ones, but a search in the parts bin uncovered a 16v one so I went with that. Let me add that getting the power supply BOX out of the synth was a bit of a pain in the ass, as it is this huge metal high-sided tray kind of thing, and to get to the power supply board you have to remove everything that's above it, see here:

There's a PCB with the power switch and socket for the plug there, and another PCB with an IC that needs to be screwed to the chassis of the power box thing. Pain in the ass, but just takes time and attention to get done. In the end, the thing works fine now. I'll probably mess with it for a few months and then sell it, who knows.

Meanwhile, I've been playing a lot with the JD-08 and the JX-08, slapping them into the K-25m keyboard and doing sound design with the thing on my lap. I was really impressed with the JD, so much so that I've decided to sell the JD-800 I have. That thing is a tank. SOOOO big. But yeah Roland really nailed the JD-800 sound with the JD-08. And it's got lots of polyphony as well as a B memory bank, so it's like having a card with the JD-800. I wish the sliders were just a but bigger though. Fuck those things are tiny!

That's all for this time, my invisible pals out there in internet land.

Electronic component:

An electronic component is any basic discrete electronic device or physical entity part of an electronic system used to affect electrons or their associated fields. Electronic components are mostly industrial products, available in a singular form and are not to be confused with electrical elements, which are conceptual abstractions representing idealized electronic components and elements. A datasheet for an electronic component is a technical document that provides detailed information about the component’s specifications, characteristics, and performance.

Advantages of Electronic components:

These leads connect to other electrical components, often over wire, to create an electronic circuit with a particular function (for example an amplifier, radio receiver, or oscillator). Basic electronic components may be packaged discretely, as arrays or networks of like components, or integrated inside of packages such as semiconductor integrated circuits, hybrid integrated circuits, or thick film devices. The following list of electronic components focuses on the discrete version of these components, treating such packages as components in their own right.

Classification Electronic components:

Active components rely on a source of energy (usually from the DC circuit, which we have chosen to ignore) and usually can inject power into a circuit, though this is not part of the definition.[1] Active components include amplifying components such as transistors, triode vacuum tubes (valves), and tunnel diodes.

Passive components cannot introduce net energy into the circuit. They also cannot rely on a source of power, except for what is available from the (AC) circuit they are connected to. As a consequence, they cannot amplify (increase the power of a signal), although they may increase a voltage or current (such as is done by a transformer or resonant circuit). Passive components include two-terminal components such as resistors, capacitors, inductors, and transformers.

Electromechanical components can carry out electrical operations by using moving parts or by using electrical connections.

Most passive components with more than two terminals can be described in terms of two-port parameters that satisfy the principle of reciprocity — though there are rare exceptions.[2] In contrast, active components (with more than two terminals) generally lack that property.

Component description of PCBA patch processing

PCBA patch processing mainly includes two major processes: PCB circuit board production and SMT patch processing. Electronic components are indispensable in the process. Electronic components are the basic part of PCBA patch processing and an important factor affecting the performance and quality of PCBA finished products. So what are the commonly used electronic components for PCBA patch processing?

1. Resistor

Resistors are electronic components with resistance characteristics and are one of the most widely used components in PCBA processing. Resistors are divided into fixed resistors and variable resistors (potentiometers), which play the role of voltage division, current division and current limiting in the circuit.

2. Capacitors

Capacitors are also one of the basic components in PCBA processing. They are components that store electrical energy and play the role of coupling, filtering, DC isolation and tuning in electronic circuits.

3. Inductor coils

Inductor coils are referred to as inductors and have the function of storing magnetic energy. Inductor coils are usually composed of skeletons, windings, shielding covers, magnetic cores, etc.

4. Potentiometers

Resistors with variable resistance values, that is, resistors that can be continuously adjusted within a specified range, are called potentiometers. The potentiometer consists of a housing, a sliding end, a rotating shaft, a ring resistor and three lead-out terminals.

5. Transformer

The transformer consists of an iron core (or magnetic core) and a coil. The coil has two or more windings, of which the winding connected to the power supply is called the primary coil, and the remaining windings are called the secondary coil.

The transformer is a device that converts voltage, current and impedance. When an AC current flows through the primary coil, an AC magnetic flux is generated in the iron core (or magnetic core), causing a voltage (or current) to be induced in the secondary coil. The transformer is mainly used for AC voltage conversion, current conversion, power transmission, impedance conversion and buffer isolation, etc. It is one of the indispensable important components in the PCBA machine.

6. Crystal diode

The crystal diode (i.e. semiconductor diode, hereinafter referred to as diode) is made of a PN junction, electrode leads and an external sealed tube shell, and it has a unidirectional conductive characteristic.

7. Crystal triode

The crystal triode (hereinafter referred to as triode) is the core device for signal amplification and processing, and is widely used in PCBA machines.

8. Field Effect Transistor

Field effect transistor (FET for short) is also a semiconductor device with PN junction. Unlike triode, it does not use the conductive property of PN junction, but its insulating property.

9. Electroacoustic Device

The device used to complete the conversion between electrical signal and sound signal in the circuit is called electroacoustic device. There are many types of it, including speakers, microphones, headphones (or earplugs), transmitters, receivers, etc.

10. Photoelectric Device

Photoconductive devices that work with the photosensitive properties of semiconductors, photovoltaic cells and semiconductor light-emitting devices that work with semiconductor photovoltaics are collectively referred to as photoelectric devices.

11. Display Device

Electronic display device refers to a photoelectric conversion device that converts electrical signals into optical signals, that is, a device used to display numbers, symbols, text or images. It is a key component of electronic display devices and has a great impact on the performance of display devices.

12. Sensor

The sensor can sense the specified measured value and convert it into a usable signal according to a certain rule. It is usually composed of a sensitive element and a conversion element.

13. Surface Mount Components

Surface mount components (SMC and SMD) are also called patch components or chip components. They include resistors, capacitors, inductors and semiconductor devices, etc. They have the characteristics of small size, light weight, no leads or very short leads, high installation density, high reliability, good vibration resistance, and easy automation.

14. Thyristor

SCR, short for silicon-controlled rectifier, is a high-power semiconductor device with a four-layer structure of three PN junctions, also known as thyristor. It has the characteristics of small size, relatively simple structure and strong functions, and is one of the more commonly used semiconductor devices.

15. Switches, relays, and various connectors

Switches are used to cut off, connect or convert circuits in electronic equipment. Relays are automatic control devices that will change the output in a jumpy manner when the input quantity (electricity, magnetism, sound, light, heat) reaches a certain value.

SMD Component Package Sizes: A Comprehensive Guide

One of the most crucial things you come across when you get deeply into the production of Printed Circuit Boards (PCB) is surface mount device (SMD) parts. Surface-mount devices (SMDs) are a necessary parts of modern electronics because of their efficiency, small size, and simplicity of automation in assembly. Therefore, a detailed understanding of SMD packages components is crucial.

This blog will walk you through the SMD component's packages sizes, compatibility and how this can impact your PCB designs.

Why Package Size Matters

There are multiple components of your PCB that are affected directly by the SMD package size:

Board Space: As the components and packages size have been reduced significantly in recent days, more components can be adjusted and assembled onto the restricted board surface.

Assembly Efficiency: The assembly machines, which are designed to pick and place, can handle larger packages more quickly, which reduces the assembly and material handling time and production cost on assembly.

Performance: The heat dissipation capability is directly proportionate with the packages size. Therefore, bigger packages offer better heat management for components with a lot of power.

Cost: Due to larger packages, faster assembly and less material usage is possible, the overall cost can be reduced. 

Navigating SMD Package Sizes

A few typical types of SMD package sizes are listed below:

Capacitors and Resistors:  These passive parts are available in the most varied sizes. For high-density boards, there's the popular "0201" (0.6 mm x 0.3 mm) and the bigger "1206" (3.2 mm × 1.6 mm) for improved handling and power dissipation.

Inductors:  The inductance value and current rating determine the size of the SMD inductor. For low-profile uses, go with a smaller alternative such as a "0402" (1.0 mm x 0.5 mm), while for higher inductance requirements, go with a bigger "1210" (3.2 mm × 2.5 mm) box.

Diodes and transistors:  These active components commonly use the SOT package family. A bigger "SOT-223" (6.7 mm x 3.7 mm) is appropriate for higher power applications, while the more popular "SOT-23" (2.9 mm × 2.4 mm) strikes a nice compromise between size and functionality.

Integrated Circuits:  The sizes and forms of IC packages are extremely varied. For high-density connections, common solutions include the Quad Flat Pack (QFP) with square leads on both sides, the Small Outline Integrated Circuit (SOIC) with gull-wing leads, and the Ball Grid Array (BGA) with solder balls underneath the package.

Below table will give you a comprehensive comparison (Ref-1 & Ref-2).

Selecting the Right SMD Package Size:

Choosing the optimal SMD package size involves a delicate balance between various factors:

Board Space Constraints: Minimalist components, such as "0201" resistors or "SOT-23" transistors, are ideal when board space is limited. Nevertheless, make sure that these little parts can be reliably handled.

Performance Requirements: To improve heat dissipation performance, select larger packages such as "SOT-223" transistors or "1206" resistors for high-power components.

Manufacturability: You need to think about how well you do the assembly design. In the case of smaller packages, the cost depends on the expertise and tooling requirements for manufacturing. It is essential to balance miniaturization and efficient assembly.

Even though you want to use smaller components and packages, make sure about the easy availability of the components. Otherwise, your supplier will find it hard to meet the delivery timeline. Moreover, if you want to keep production on schedule, it is a wise decision to use easily accessible packages with larger sizes.

Get in touch with the PCB Power if you have questions. Our assembly capabilities and team of experts will give their insightful recommendations.

Advanced SMD packages

The world of SMD packages extends beyond basic rectangular shapes. Here's a glimpse into some advanced options:

Leadless Chip Carrier (LCCC): A leadless chip carrier (LCCC) is a rectangular or square packages that has solder bumps on the bottom for connections with a high density.

Ball Grid Array (BGA): By arranging solder balls beneath the whole device, Ball Grid Array (BGA) provides even greater density and superior electrical performance. Nevertheless, specialized assembly procedures are necessary for BGAs.

Quad Flat No-Lead (QFN): Compared to BGA, Quad Flat No-Lead (QFN) has better mechanical stability thanks to leads that extend from each of the four corners.

Although they necessitate sophisticated assembly methods and meticulous design, these advanced packages are perfect for space-constrained high-performance devices.

Final Words:

Knowing the sizes of SMD packages can help you make better decisions about PCB design, component sourcing, and assembly. It takes considerable thought to balance space constraints, performance needs, manufacturability, and component availability when selecting the ideal package size for your project. Keeping open lines of communication with your PCB manufacturer and component suppliers is essential to ensure an efficient and effective PCB assembly process.

Through Hole PCB Assembly

THT PCB Assembly Manufacturer – One-stop service

What’s mean for Through Hole (THT) PCB Assembly and Surface Mount Technology（SMT）PCB Assembly ?

Surface Mount Technology (SMT) is necessary for PCB assembly. If the PCB has no through-hole components, Through Hole (THT) PCB Assembly is not needed.

SMT assembly: SMT stands for surface mount technology, which is a versatile PCB assembly technology. Currently, all electronic components can be made into surface-mounted devices (SMD). SMDs are interconnected to the PCB pads with solder paste. SMT assembly is automatic.

THT assembly: THT, or PTH or DIP, means through-hole technology. The electronic components that require THT assembly have long pins. Usually, they are capacitors, fuses, and connectors. The PCB is pre-drilled, and these components' pins plug in the holes and wave reflowed. THT assembly is manual.

In the PCB assembly process, SMT assembly happens before the THT assembly.

What are the benefits of Through Hole PCB assembly?

Through-Hole PCB Assembly comes with a range of benefits including:

Withstanding stress-As opposed to SMT components, through-hole components are known for their ability to withstand mechanical and environmental stress.

Perfect for large components-Through-hole works well for large components that have to undergo high power and high voltage

High heat tolerance-Known for their high heat tolerance, they find application in a number of industries, particularly military and aerospace.

Ease of Prototyping- Through-hole PCBs also lend themselves to ease of prototyping and improved reliability

High Reliability-Through-hole PCBs are best used for high-reliability products that require stronger connections between layers.

Little surprise then, that even though surface mount components allow for denser configurations, for larger and heavier components that require strong bonds, through-hole technology has remained resilient and relevant.

What are the capabilities you offer for Through Hole PCB assembly?

We provide through-hole PCB services to a variety of industries including medical, electronics, instrumentation, and military, all thanks to our complete assembly capabilities:

• Hand soldering

• Functional test and automated inspection

• Support various types of PCBs including metal core PCBs, Rigid PCBs, Flex-rigid PCBs, FR4 PCBs, etc.

Disadvantages of Through Hole Assembly

Like any other manufacturing or assembling techniques, Through Hole PCB Assembly has its disadvantages too.

These include:

Longer production time-It takes a lot of time to drill the multiple holes through which the leads are expected to run.

Expensive-because the drilling process is difficult and time-consuming, it increases the cost of production

Minimizes space on the boards-drilling the holes on the surface of the board limits the routing area for tracing signals.

Also, by feeding the leads through the board, only one of its sides is usable, thus making the THT PCB a bit slower in operation speeds.

Through Hole Assembly Components – What are the Best Components for Through Hole Assembly?

Radial lead components

Axial lead components.

Types of Through Hole PCB Assembly

There are two (2) main types of the Through Hole PCB Assembly. The first is the Automated Through Hole PCB Assembly. The second is the Manual Through Hole PCB Assembly.

On the one hand, the automated variant is roundly touted to be faster and cost-effective because it takes little time to be completed. It also demands little human inputs, which makes it cost-effective.

On the other hand, the manual Through Hole PCB Assembly involves the traditional or manually-operational model of drilling the holes into the Printed Circuit Boards (PCBs). This model tends to take time and attracts more costs.

Functional tests and automated inspection for Through Hole PCB Assembly

Using automated inspection is very critical in minimizing turnaround time to ensure timely delivery of the boards.

Conclusion

As you can see, Through Hole Assembly of PCB can be time consuming.

However, in some applications, it is worth it more so when mounting heavier and bulkier components.

You can easily achieve the strength by soldering the components on the reverse side as you have seen.

In fact, it is virtually impossible to pull components assembled using Through Hole Assembly.

The good news, today’s guide has simplified the Through Hole PCB Assembly technique.

Through-hole PCB Assembly Testing and Inspection at Hitechpcba

In-Circuit Testing: 

This type of testing is conducted for high volume production lines, and helps us check every minute soldering and other components in detail.

Automated Optical Inspection: Abbreviated as AOI, these tests are performed to ensure that product is free from soldering, component, and BGA defects.

Automated X-Ray Inspection(AXI): 

This testing is performed to inspect insufficient fills, short circuits, fills, etc. The automated X-ray inspection helps reduce the number of defects and improve the quality of the Through-Hole circuit.

Burn-in Tests: 

These tests detect components’ failure or reliability in real environments.

Assisted Visual Inspection: 

Our experts use a wide range of advanced visual inspection equipment to perform a detailed inspection of soldering and component placement accuracy.

What’s difference between SMT assembly and THT assembly?

Most contract PCB Assembly manufacturers concentrate on their surface mount technology capabilities for PCB assembly. The SMT lines can be almost completely automated making it possible to run a high volume of boards with little human intervention and a low cost per board. Through whole assembly whether automated or manual is a slower process, it takes resources away from the high-volume business that many manufacturers prefer.

Only about 10 percent of the parts we buy are through-hole. Nearly 75 percent of the boards we run are mixed technology, which is a combination of through-hole and SMT parts one reason for this is that nearly half of our board assemblies are for high powered boards which use capacitors inductors and transformers to transfer energy. The size of these components is proportional to the energy they can store so for a high-power board we need to use some fairly large and heavy components and that means through-hole technology, in addition things like customer accessible connectors, that have to withstand stress as cables are connected and removed are likely to be through-hole components. Through-hole components are held in place by the pins as well as the solder so you can get a much stronger and more reliable mechanical bond than with surface mount components that have only solder to hold them in place. If a contract manufacturer is focused on higher volume SMT business, it's important to understand how they will handle through-hole components when you need them at z-axis. We run mixed technology boards every day we have a modern stuff line with a paperless process for assembly instructions and assemble in a single piece flow from the stuff line to a wave solder to inline inspection, d-paneling, qc testing. 

In addition to PCB Assembly, be it through hole or surface mount, at Hitech Circuits Co., Limited we also undertake PCB assembly rework offering complete reliability, high quality and optimal costs. Not only are we well-versed in inventory management, fabrication and process control, we also have a stringent control on vendor component management.

SMT production process

Program the SMT placement machine

According to the BOM position map provided by the customer, program the coordinates of the location of the components. Then carry out the first piece with the SMT chip processing data provided by the customer.

Printing solder paste

The solder paste is stenciled to the PCB board where the electronic component SMD needs to be soldered to prepare for the soldering of the components. The equipment used is a screen printing machine (printing machine), which is located at the forefront of the SMT chip processing production line.

SPI

Solder paste detector, detects whether the solder paste printing is a good product, whether there is less tin, leaking tin, more tin and other undesirable phenomena.

4.SMT

Accurately install the electronic components SMD on the fixed position of the PCB. The equipment used is a placement machine, which is located behind the screen printing machine in the SMT production line.

The placement machine is divided into high-speed machine and general-purpose machine.

High-speed machine: used to paste components with large pin spacing and small pin spacing

Universal machine: paste small pin pitch (pin density), bulky components.

High temperature solder paste melting

Mainly, the solder paste is melted at high temperature, and after cooling, the electronic components SMD and the PCB board are firmly welded together. The equipment used is a reflow soldering furnace, which is located behind the placement machine in the SMT production line.

AOI

Automatic optical detector to detect whether the soldered PCBA components have poor soldering, such as tombstone, displacement, empty soldering, etc.

Visual inspection

The key items of manual inspection and inspection: whether the PCBA version is the changed version; whether the customer requires components to use substitute materials or components of designated brands and brands; IC, diodes, triodes, tantalum capacitors, aluminum capacitors, switches, etc. Whether the direction of the directional components is correct; defects after welding: short circuit, open circuit, fake parts, fake welding.

Packaging

Products that have passed the test will be packaged separately. The commonly used packaging materials are anti-static bubble bags, electrostatic cotton, and blister trays. There are two main packaging methods, one is to use anti-static bubble bags or electrostatic cotton into rolls, which are the most commonly used packaging methods at present; the other is to customize blister trays according to the size of PCBA. Put it in a blister tray and unpack it, mainly for PCBA boards that are sensitive and have vulnerable patch components.
