The ENIG process will yield between 3-7 micro inches (110 - 275 microns) of gold over the nickel barrier. This thickness range is pretty much the limit as this is a self limiting displacement reaction process. Once all surface nickel ions are repl

Frank, I am not talking about the masking on the PCB. I am actually talking about the masking on the solder side of the BGA. We have a very very high dollar BGA and are trying to reclaim alot for reuse. When we remove the BGA from the assembly, you

We use Selective Wave Pallets for the vast majority of our boards with great success. Many of our boards have BGA's and connectors on both sides, which for the most part then require the Selective Wave Pallet. We successfully use pallets up to 10mm t

At APEX I was able to witness the BEAM WORKS Selective Laser Soldering machine operate.Truly impressive. When they told me they could solder a BGA component, I old them they were HIGH as a kite. The board they demonstrated had 4 BGA's on it. When the

One very important consideration in your situation is to determine if you have moisture sensitive components on these boards. If you have any device classified level 3 or higher then you have a very high level of risk associated with moisture sensit

The Smart Sonic 440-R SMT detergent is certified safe and effective by the EPA (I downloaded the documents from their web site). Is this true of the other chemistries that you referenced? If so, where can I find the documentation? If not, why not?

Ryan, It is a must that you try to get a partner in Japan that can help you market your product. Japan is not a very open marketplace. Many of the companies will only deal with other Japanese companies. I used to work at a company that was suc

You can buy plenty of paste height measuring systems today, ranging from full 3D laser systems to systems using an oblique light line which will measure the paste height only. I found that the lowest cost option was to attach a DTI to the focus contr
