hi, I wondering if anyone have any information on intermetallic growth in 80Au20Sn solder alloy. I have read that it has high reliability. Which bring an important question to my mind. What about Gold embrittlement ? Bye Indy

You're thinking correctly. 80Au20Sn is incompatible with: * Sn/Pb * In/Sn * Sn/Pb/In * Sn/Pb/Bi Contact your solder supplier to obtain pictures of IMC.

We purchased this wave solder machine used. It came without the operating software (TECDEV). I want to know how to adjust the temperature deviation setpoint. Does anyone know how to do this? Thanks in advance, JG

I have a connector which has very weak joints. Solder fractures easily. On inspection the solder is very grainy and full of voids. Process is 63/37 no clean. Any thoughts? Phil

I am looking for a supplier or a manufacturer who can help me with Titanium Fingers for our Electrovert Econopak Plus wave solder. I am looking for the "v" groove type and also the 90 degree type fingers. I am in Australia. Thanks.

Some questions: Is the peelable/spot masking only being applied to the earthing points on the one side or to both sides? Is the peelable mask you are using specifically designed for coating masking or is it the same as that you use for masking sold

Has anyone in the industry had even a fair amount of success inspecting reflowed solder joints to IPC class 3 standards? I am not interested in hearing from system reps or people who work for an AOI manufacturer. Thanks,

90% of the assemblies our company produces are class 3 and we have no problem at all inspecting or getting class 3 quality through reflow. Rarely do we have touch up because of insufficient or poorly reflowed solder joints. What are the problems you
