Die fünf Hauptfunktionen von Lötstopp-Lochverschlüssen

1️⃣ Verhindern des Fließens von Lötzinn durch die Durchkontaktierungen und Vermeidung von Kurzschlüssen während des PCB-Wellenlötens, insbesondere wenn die Durchkontaktierungen auf BGA-Pads platziert sind. Es ist notwendig, die Löcher vor der Vergoldung zu verschließen, um das BGA-Löten zu erleichtern.

2️⃣ Vermeiden von Flussmittelrückständen innerhalb der Durchkontaktierungen.

3️⃣ Nach der Oberflächenmontage und Bauteilplatzierung muss die Leiterplatte auf einer Testmaschine einem Vakuumsaugtest unterzogen werden, um einen Unterdruck für die Fertigstellung zu erzeugen.

4️⃣ Verhindern des Fließens von Lötpaste in die Löcher und Vermeidung von Lötfehlern, die die Lötung während der Montage beeinträchtigen könnten.

5️⃣ Verhindern des Herausspringens von Lötkugeln während des Wellenlötens, was zu Kurzschlüssen führen könnte.

Peavey LM⁽ᵗᵐ⁾ 8

I expected this to be a normal architectural mixer, but actually its a really nice rack mixer. it looks like peavey targeted this one at tv and recording studios. there seems to have been a stage vertion in black, but its pretty clearly not as well made.

This also has some of the prettiest pcb's Ive ever seen. 

one thing I noticed that there is quiet a bit of empty space in the case, and I'm contemplating adding a spring reverb, normaled to one of the aux sends.

[cyle]

just another wild hardware hacking prototype for fun. now i know why nobody uses white PCBs, the solder burns are super obvious and painful to look at.

A year ago I got an idea for the Teamwork Termites: circuit board themed termite robots that solder each other into a gigantic fused form, a Teamwork Titan. Tons of off and on designs later I am really happy with this!

I like to think the hundreds of units comprising the Titan form have a hive mind, but they don't always agree in unison about everything. So sometimes simple instructions like "build our Titan form with SIX LIMBS, everyone!" gets interrepted in incongruous ways.

Do you also host a chapter of the fumo club

I don’t actually own any fumos at all. They’re kind of overpriced for what they are, and they don’t have PCB Yukari so they’re automatically invalid and stained with sin. Any Touhou merchandise line that creates an IN/IaMP Yukari first rather than the one where she’s chilling out is indelibly cursed. Your main image of Yukari is the one where she’s working? Where she’s having to do troublesome things? Where she’s not getting her healthy six hours of lying around yawning and stretching time? You’re cruel to her.

LED PCB Assembly

What is the LED Circuit Board assembly?

Generally, LED PCB assembly is considered to be a circuit board that has the LED components soldered to it. The LED is soldered to the printed circuit board and features a chip that creates the light as electrically connected. A thermal heat sink and a ceramic base are used to bond the chip. Not all the PCB products can be used in Led industry, as an LED PCB is easy to create a high volume of heat, but making it hard to cool with traditional methods. For this reason, metal core PCB is widely used in LED application because of their enhanced ability to dissipate heat, especially aluminum pcb is often used to fabricate PCB for LED lights.

We’ve had great LED PCB assembly experiences with top LED chips to brand such as Cree, Luxeon, Osram, Nichia, Lumileds, MLS, EVERLIGHT, Samsung, LG, Seoul., etc. PCB LED lights can be incorporated into numerous lighting applications due to their combination of excellent energy efficiency, low cost and maximum design flexibility.

Application of LED PCB Assembly

LED PCB Assembly specification

Number of layers for LED PCB

These layers are made up of aluminum and magnesium, but now have Copper base material  and Ceramic base materials for LED PCB industry, we can meet it.

Aluminum LED PCBs stand out among other PCBs because it has a good insulation characteristic and has a better machinery performance, the cheap cost is one important factor too.

Types of layers for LED PCB Assembly

Normally, the base layer is made using aluminum alloy metal.

This aluminum alloy substrate used in making the base makes it ideal for through-hole technology which transfers and dissipates heat.

A thermal insulation layer is made using some ceramic polymer which has good viscoelasticity characteristics.

It is highly heat resistant and protects the PCB against heat and mechanical stress.

The circuit layer, which is covered by a copper foil which can range from one to ten ounces.

LED Board type- single or in panel

Some boards are shapeless. For this reason, LED PCB panels are used. This reduces time, labor production and testing time.

Some LED PCB Assembly is done on a single board while others are done on panel boards.

LED PCB Assembly Process

Roughly, the PCBA process can be divided into theses phases: soldering paste printing > SMT (surface mounted technology) > reflow soldering > AOI (automated optical inspection)> THT (through-hole technology) > wave soldering > touch-up and cleaning > IC-programming > FCT (functional tests) > aging testing. 

Below we show you the process.

Step1. Summarizing Project Information

Before contacting your supplier, make sure you have all the project information. Suppliers will need info following for quoting LED PCB assembly:

Gerber

BOM

LED PCB specification

Quotation quantity

Once you have gathered these information, you can contact us and request for a quote.

Of course, you can also provide the schematic, LED PCB Assembly pictures and even samples to us. The more details they have, the more accurate the supplier’s quotation will be.

Step2. Discussion and details about custom LED PCB Assembly

Different projects will have different requirements. Remember the special requirements mentioned in step 1? That’s going to be the focus of this session. Equipment and engineering capacity will not be identical between suppliers. Make sure your supplier has the equipment to produce and assemble major components and the corresponding testing capabilities.

For example, some vendors don’t have X-ray testing equipment, which means they can’t check the mount quality of BGA chips. Outsourcing this step will increase risk and cost. That’s what you don’t want.

Also, pay attention to time taken by the supplier to quote. Motherboards often contain hundreds or even thousands of components, and they are supplied by different manufacturers. To ensure the quality of the components, the supplier sourcing team will make multi-inquiries from these manufacturers or authorized suppliers to match customer’s requirement, which usually takes 2-3 business days, and even longer for some scarce chips. Therefore, if your project is complex and the supplier quotes you within few hours, double check with them.

Step3. Sample and feedback

After confirming the PI, the supplier will usually provide pre-production samples for your approval. At the same time, the supplier will also confirm with you the logistics plan of the bulk goods. Make sure they understand your shipping requirements, including details on packaging, customs clearance, taxes, etc.

For us to have a successful LED PCB Assembly process, its functions must be defined. Compliance requirement is defined to reduce the effect when components are selected.

The Bill of Materials is then generated from the information installed on the LED PCB.

All this information is used to assemble components which are identified from MOB to the LED PCB.

After that, the routing of traces is determined to each component, based on the size, shape of the circuit board and location of connectors.

Hitech Circuits is trusted by thousands of electronic engineers on their LED PCB assembly projects, from consumer, led bulb to precisely medical LED light, we can help you from the beginning of design stage; From commercial flood LED to industrial high power LED, from automotive LED to military LED, Venture is the perfect place for your LED PCB assembly requirement.

Two of the three PCB's that make up the piece of rack gear I call my DI box.

on the left, is a clone of the EQ section from a 70s Sunn Coliseum Bass amp, Half assembled.

It is a 4 knob eq, with controls idiosyncratically (but accurately) labeled high, mid, hi bass, and low bass. the high and mid controls each have a 2 position frequency switch. The result is a very versatile, but still easy to tune tone control.

On the right is my standard line output pcb, fully assembled, except for the gain setting resistor.

this is a transformer coupled design, which uses a small power amp, to ensure it cant be overloaded. I didn't know it when I designed this, but this is almost identical to the design used by urei in the late 1970s, notably in the 1178, and la4a.

It has better isolation and a lower noise floor then a modern integrated design, and is actually cheaper then the IC solutions sold by That crop.

I used the same pcb with a different transformer as a reverb driver in my rack mount spring reverb.

If you have ever listened to my music you have heard both these circuits on synth, guitar, bass, and even my drum machines. I've also sold several identical units to local studios.

also, the spring reverb is my go to reverb now. So its on most tracks as well.
