DOTSLASER-UV Lasers And Their Applications in Laser Processing

First, UV laser characteristics description

The ultraviolet laser wavelength is short, energy concentration, high resolution, especially has the characteristic of "cold processing", can directly destroy the connection material chemical bond, without producing to the peripheral heating, therefore becomes the ideal tool of processing fragile material, and can carry on the perforation, cutting, ablation to many kinds of materials, has the wide application in the field of micromachining.

1. Gas UV laser

Gas UV lasers are excimer lasers, argon ion lasers, nitrogen molecule lasers, fluorine molecule lasers, helium cadmium lasers and so on. The gas ultraviolet laser used for laser processing mainly has the excimer laser.

Excimer is a kind of excimer in the excited state composite into molecules, in the base state dissociation into atomic unstable connective matter. In excimer laser systems, the leap occurs from the bound excited to the repelled fundamental state, and is therefore a free leap of bound origin. Excimer laser is a kind of pulsed laser, the working medium is generally a certain proportion of mixed inert gas and strong electron halogen element gas, when the base state of the inert gas atom is excited, the extra-nuclear electron is excited to a higher orbit and thus change the electronic shell layer all filled state, so that it and other atoms to form an excimer, when the excited state of the molecule leaps back to the base state, immediately decomposed, reverted to the original properties! The laser emits high energy ultraviolet laser, which is amplified by the resonant cavity and releases photons at the same time.

2. Solid-state ultraviolet laser

The general produce ultraviolet excitation spectral line method has two kinds: one is directly using infrared all solid-state laser triplex frequency or quadruple frequency obtain 355nm or 266nm ultraviolet excitation spectral line, another kind of method is first use frequency doubling technology to get the second harmonic, then use and frequency technology to get ultraviolet excitation spectral line. The former method effective nonlinear coefficient is small, the conversion efficiency is low, the latter method because of the use of the second nonlinear polarization rate, the conversion efficiency is going to be higher than the former kind many. The solid ultraviolet laser relative to the excimer laser has the advantages of compact volume, easy maintenance, easy operation and so on.

3. Application advantages

There are three advantages of UV lasers in laser processing: first, the shorter wavelength of UV lasers can process very small parts; Two is the ultraviolet laser for laser processing directly destroy material chemical bond, is "cold" processing, has a small heat affected area; Three is most materials can effectively absorb ultraviolet light, can process many infrared and visible light laser processing can't material, and the ultraviolet laser especially solid-state UV lasers are becoming increasingly compact, high average power, easy to maintain, easy to operate, low cost and high productivity. Therefore, it has been widely used in laser processing fields such as bioengineering, material preparation, all-optical optical device production, integrated circuit board and semiconductor industry.

What is a Laser Engraver?

The laser engraving machine uses the thermal energy of the laser to engrave materials. The CO2 laser tube in the laser engraving machine is its core. Generally speaking, the use range of laser engraving machine is more extensive, and the engraving accuracy is higher, and the engraving speed is faster. And compared to the traditional manual engraving method, laser engraving can also achieve a very delicate engraving effect, no less than the level of hand engraving. It is precisely because the laser engraving machine has so many advantages, so now the application of laser engraving machine has gradually replaced the traditional engraving equipment and methods, and has become the mainstream engraving equipment.

If your company is in the manufacturing, electronics, or even medical sectors, sooner or later, you will require laser marking for your products and components. The best solution for this is fiber laser engraver machine. The non-contact fiber laser marking process is well-known among customers for the following reasons:

Durability

High-temperature resistance

Application to various materials

Use of nontoxic inks, solvents, and acids.

But simply understanding the advantages of fiber lasers is not enough. There are other factors that you need to consider.

These three basic factors can help you make an informed decision when purchasing a fiber laser marking system for your company.

Of course, nearly all customers will pay more attention on price. In China market, we can find so many different price. After confirmed what kind of machine we need, then we need to choose the best supplier between thousands of supplier.

Next time we will talk how to choose suppliers of fiber laser engraver.

Factors for Choosing a Fiber Laser Engraver Machine

The following are parameters you need to keep in mind when choosing a fiber laser engraver machine.

A laser with better beam quality can remove material much faster, with better resolution, and improved quality.

Laser markers with high beam quality can produce a focused optical spot size down to 20 microns.

High beam quality lasers are particularly suited for scribing and cutting materials such as silicon, aluminum, and stainless steel.

Beam Quality: Beam quality is an important parameter, as it affects the laser’s processing capability. The reasons for the importance of beam quality are simple:

Single or Multi-mode Lasers: There are two types of fiber lasers – single mode and multi-mode. Single mode fiber lasers deliver a narrow, high intensity beam that can be focused down to a spot size as small as 20 microns and are generated within a fiber core of less than 25 microns. This high intensity is ideal for cutting, micro machining, and fine laser marking applications. Multi-mode lasers (also called higher order mode), use fibers with core diameters greater than 25 microns. This results in a beam with a lower intensity and large spot size.Single mode lasers have the best beam quality, while multi-mode lasers allow for the processing of large components.

WHY SLA IS THE CHEAPEST 3D PRINTER?

Technologically, our world is advancing at a very fast pace. The 21st century marks the beginning of many technological wonders including Virtual Reality and 3D printing. In the past 5-10 years, the use of 3d printing technology has largely increased. Various fields including construction, architecture, education, fashion, healthcare and food all use 3D printers to convert their virtual work into reality. WHAT ARE 3D PRINTERS?

SLA 3D printed parts  3D printers are computer based machines that bring materials together to create a three-dimensional object. 3D printing changes the way products are produced ranging from very simple objects like toys to complex objects like body parts. HOW DO 3D PRINTERS WORK? During the 3D printing services, thousands of tiny pieces of the object to be made come together layer by layer. These layers stick together and finally form the solid object. WHAT ARE THE DIFFERENT TYPES OF 3D PRINTERS? The different types of 3D printers used are the following: Stereolithography (SLA) Digital Light Processing (DLP) Fused deposition Modelling (FDM) Selective Laser Sintering (SLS) Selective Laser Melting (SLM) Electronic Beam Melting (EBM) This article talks about why SLA 3D printers are the cheapest among the above mentioned ones. But firstly, we need to understand what are SLA 3D printers and how do they work. WHAT IS STEREOLITHOGRAPHY? (SLA) This is a type of 3D printing which deals with creating various objects like models and patterns with great intricate detailing. The parts of the objects are made as the tiny materials come closer to each other layer by layer with the help of a liquid polymer that hardens when it comes in contact with UV laser light. Basically, a liquid plastic solidifies to form the solid object. HOW DOES IT WORK? Basically SLA consists of the following four parts- A tank which is filled with the liquid plastic known as Photopolymer. A perforated platform on which the solid object is formed. The UV laser light. The computer which controls the platform. Process: When the UV light comes in contact with the photopolymer which is present over the perforated platform, then the first layer is formed. As the process continues, layers are added over the existing layers and finally the three dimensional object is made. WHY SLA IS THE CHEAPEST 3D PRINTER? The SLA technology was first introduced in 1986 by Charles Hull. Since then many different types of 3D printing technologies have emerged but SLA continues to be the best. Being one of the oldest 3D printing methods, it can be considered cheaper than its predecessors. The technology used to produce 3D printing objects via the SLA method is much cheaper as compared to the technology used by SLS or SLM. SLA printers are mostly found in larger companies. But recently, many companies manufacture low-cost SLA printers which are being sold to satisfy the general public. These printers provide the same advantages as those of the costlier ones. Nowadays, you can get information on the internet on how to make affordable SLA printers at home that provide the same advantages as the ones available in the market without having to waste your money unnecessarily.

Global Laser Marking Machine Market is segmented on the basis of type of machine, applications, and region. Laser is a device that emits a beam of coherent light through an optical amplification process. A laser can be considered as a system which stores light energy and releases it in a much localized area, the emitted energy has very high density energy. Laser Marking, also known as laser engraving or laser etching, is a marking method which utilizes laser light to mark materials using a fine spot diameter ranging from 0.002' to 0.01'. The laser marks with short pulses (30 nanoseconds), providing precise control, and negligible heat input to the part.

Laser marking stands for marking or labeling of work pieces and materials with a laser beam. It is the production of human- and/or machine-readable identification or information on a material such as barcode, date/lot code, serial number or part number, others. A fast and clean technology, laser marking is rapidly replacing older marking methods.

Carbon migration laser marking can be applied to metal and metal alloys. Carbon migrates to the surface via a heating process which produces dark markings. Heat is applied at a rapid pace. It can be used in Aerospace, jewelry engraving, metal working, and others. Foaming Laser Marking - is used when a plastic is darker and the desired end result is a lighter color (usually white, gold or various tan shades). This change in color occurs by creating a molten burn on the surface that is both contained and controlled. When the surface is melted, it creates an atmosphere of foaming gas bubbles. Foam laser marking can be used for marking on ink cartridges, keyboards, cosmetic packaging, others.

In Coloration Laser Marking, the process of adding color to a plastic or metal, or coloration laser marking, is created by heating specific parts of a surface based on the anticipated outcome.

New Post has been published on Quality, Manufacturing & Product Development in China

New Post has been published on http://quality-manufacturing.org/electronic-prototype-fabrication/

Electronic Prototype Fabrication. Part 2: How to make electronic PCBA prototype

In a previous post (Electronic Prototype Fabrication. Part 1: Why making electronic PCB prototype is useful) I explained why electronic prototyping is an important step in the product development process of an electronic product.

In this blog post you will learn how PCB and PCBA prototypes are made during the electronic product development phase. Normally, this phase comes once the electronic engineering is achieved. So, at this point we can consider PCB Schematic is completed, PCB Layout has been drawn and verified, Bill of Material is stabilized, Gerber files including layer, component positioning and drilling have been generated.

What are the different steps of making electronic prototype and how do we handle them

Below is a general scheme of the processes involved in creating electronic pcb prototypes. You can see there are quite a few steps and most of them got their dose of risks of failure. Astonihly, but in order to remain competitive, in 2017 we are stilling making PCB prototype by hand.

1./ Blank PCB prototype procurement

For recall, a PCB (also called "blank PCB") is a Printed Circuit Board which doesn't host any electronic component yet. By opposition, a PCBA also called Printed Circuit Board Assembly is a PCB on which electronics components have been soldered/assembled.

This part of the process for prototype is made the same way than for manufacturing. One of the main difference is that manufacturer will try to panalize as much as possible several design of several customers on the same plate so they can optimize their costs in terms of plate allocation.

To perform this step, heavy equipment are required: several chemical bath, CNC drilling machines, CNC cutting machines, silk screen machine etc.. It uses as input the Gerber files generated by an EDA software such as Altium, Orcad Allegro, Kicad or Eagle to feed a full chain of machine creating blank PCB.

I personnaly have a database of several PCB manufacturers I have audited myself because I don't use the same PCB manufacturer for different projects. Indeed, some PCB prototype manufacturers may be capable and competitive to make 2 layers PCB but can have difficulties to process 4 or more layers with reliability. This is particulary true when it comes to high quality PCB requiring physical adjustments such as impedance matching.

Obviously, if PCB prototype quality is not proper, then your electronic pcb prototype might not work properly either. Normally, a serious supplier would make some track testing using some flying probe to verify the tracks on the PCB. If they don't do it, you might risk to receive some PCB with defects: you will solder your components and your board will not work properly. You will spend hours and hours finding out why and finally you will realize that problems comes from manufacturing. Quite frustrating !!!

2./ Electronic components procurement

It may sounds easy to do. You might think: "buy component? I can do, this like going to shopping !". In reality, it can become not that easy at all depending on how the bill of material has been established by the pcb architect and the pcb hardware engineer.

Indeed, if the hardware engineer selected components which are difficult to supply because the components is rare on the market or just outdated, then it can become a nightmare to success to find the components at decent price on the market to populate your PCB and to respect the bill of material. In some case, the components might need to be imported specifically or might need to be subsituted by another equivalent one (I recommend to avoid this, but if it is necessary then the people in charge of sourcing and procurement should ask for validation to the hardware engineer).

Another problem you may face is to buy sample components to a vendor who can also supply bigger quantities later for manufacturing with reliability, so that you can get consistency on your supply chain for your components. I see quite a lot of people who buy components in the electronic market in Shenzhen (Hua Qian Bei) to small shops. They go here and there so find some vendors selling components and buy some samples to make their prototype. Later when they want to mass produce, they have either difficulties to find another vendor more reliable for production to match exactly the same components or they need to rely on the small shop they used. Quite often the small shop will not disclose who is the real manufacturer of the component, hence you loose control on the supply chain and the shop can change the manufacturer behind your back without you know it, putting your production at risk.

Hence, when you buy components, even for sample, I recommend to buy them for reliable sources. For example, you can use Arrow or Element 14, those are big components distributor and they don't substitute components behind your back.

I recommend to be very organized when performing components procurement because it can quickly become terrible to manage: when you got a bill of material with 100 different component references you need to make sure you got all of them and you need to make sure you don't mix them (yes you can because sometimes components are not marked) !

I personnaly use some zip lock plastic bags on which I ad some sticker with component part number and I never put components of those bag unless I need to solder them.

3./ Assembling components on blank PCB

A./ Solder paste deposit

Now you got your components and your blank PCB in hand, you then need to solder components on pcb so they can connect with each other and realize your circuit which then you will test. If you are on SMD type configuration then it means your component will be soldered on pads and not trough hole. It means some soldering material should be placed and melt between components and PCB. So the question is how to place properly solder paste on pad properly (not too much, not too less).

Well here there are differents technics, some people do this by hand and it is very difficult. The best solution is to use what we call a laser net: this is typically a frame with a layer of aluminum being cut with a laser exactly to keep some opening on the surface of the pads. In short, it creates a canvas where the solder paste will be placed only on the pad. This frame can be placed on an automatic machine, but for prototype we mostly use manual one because we make very low quantity of prototype (usually no more than 5 pieces).

I can tell you the first time I tried to make a PCBA prototype I have attempted to use a hand solder, components and normal tin solder wire and it didn't work at all because components are so small that it is extremly difficult to perform a clean soldering this way. I don't mention either that soldering component with having pads below the components make impossible to solder a comopnent on a pcb with using a solder paste material.

Since then, I have my own manual laser net apparatus which I use to deposit solder paste on PCB. It gives me some ease to put exactly the necessary solder paste quantity on the right area of the PCB.

B./ Components placement

Now that you have your solder paste placed on the pcb pads you will need to place components exactly at the location of the pads so it can solder properly. This part is the most complicated part of making electronic pcb prototype. Why ? Simply because today components are so small that you can not even catch them with a tool. Now imagine you have 100 references on your bill of material, and each references got 2 components each. This is around 200 components to place on your PCB, and most of them got size around less than a millimeter length.

There are two ways to achieve this:

Pick and Place machine or mini pick and place machine: it makes automatic placement. This can be costly because machine need to be set and ready for making only 5 pieces prototype, so the settup cost outweight the product cost. However, if the pick and place is of good brand, it should be able to place all the components properly at the right location.

Manually: I usually do it this way. It can be quick for small PCB with few references and if components are not too small. I use a microscope to do this. Methodically and patiently I pick components one by one from zip lock bag reference by reference with a tool. I get my bill of material and I get my component placement scheme with me on the side of the microscope and I place components on their pad manually and very gently (because if you hit the PCB then all components you have already placed may move and then you need to restart it all over again !!). I do this for all components until the last one is place (of course you can do this only on one face at the time)

C./ Soldering

This can be considered the easiest part but actually it also got some risks here. There are different way to solder components on PCB:

Reflow oven: this is what is used in manufaturing process. Typically an oven blowing some hot air in a controlled way will make the solder paste to melt, so components can be soldered on PCB. Those oven are usually not cheap but they are usually (if used properly) the most reliable way to solder components on PCB, reason why you find them in all serious PCBA manufacturer/assemblers

UV oven: this is another type of oven using UV to heat up the environment around PCB. There are a few companies selling this, and I almost purchased some but I read so many bad comments about it that I decided it would not worth it (I particularly read that it is difficult to control the temperature and quite often the board and the component get completly burnt, not to mention I read it smells extremly bad and doesn't perform well)

Hot air reworking station: This is whay I mostly use. This is a very basic tool blowing some hot air on a pipe and it allows to decide where to blow air, when and how (at which temperature) whil still having a visual on what is done. A good way to see what is done is to check the color of the tin.solder paste. Normally it will change aspect and color when it melt and solidify. A drawback of the hot air device is it blow air, so there is a risk to move components out of their pads when you blow on them. A solution to avoid this is to reduce the air flow and to blow vertically so the force made on the component is normal to the PCB plan and it limits the chance to move components.

Hot plate: This is another device I use time to time solder component when the PCB got components on only one side: I place the PCB with solder paste and components on the hot plate and I just wait. With thermal diffusion the solder paste melt and components solder by themselves on the PCB

If everything goes well, you should get an assembled PCB made properly already, however I recommend to make a quick inspection of the PCB first visually to verify there is no soldering issue, then using microscope to review some particular part and risky area of the PCB (particularly around legs of IC)
