When soldering a component to a board, the solderability protection on the component combines with the solderability protection on the board and the solder to form an alloy. This alloy is unique for that combination of solder and solderability protec

I believe SAC305 will result in a lesser amount of Ag3Sn inter-metallic compounds being formed along the joint boundary and in the sphere. Studies have been shown to point out a significant difference between the number and size of Ag3Sn plates in SA

A few more facts: 1) China has between 100-160 cities with populations of over 1 million. America has 9 and all of Europe has 36. 2) China will produce 325,000 engineers this year....5 times as many as the United States. 40% of all American student

The trade imballance isn't even being talked about in Washington. But still I can't see why on a global scale only China can compete when it comes to making goods. Speaking of Washington cleaning house in congress sounds like good idea but truthful

I don't suggest using Pd/Ag or Ag/Pd terminated components unless you are forced to use them. You often see a line of demarcation that suggests a poorly wetted solder joint. I have had bad experiences with Pd/Ag terminated capacitors. Even when so

I am being asked to perform the same evaluation now with a Au/Pd termination varistor. We currently use a Pb/Sn process with an RMA flux. The manufacturer of the device recommends going to a 2% silver paste. What is the intended advantage with 2%

We currently have an assembly that we have to mask the surface of several (24)SMT components where thermal compound is applied at a latter operation. These component packages vary from BGA's to QFP's. After the thermal compound is applied the PWA is

Steve, You read it the same way I read it. Some of my coworkers thought that the 600 micron and under spec meant that you could use lead solder and be exempt at this component pitch. That is why I posted it on SMTNET. The exemption specifically s
