The diode doesn�t appear completely broken. It takes a bit white color (cristal break, I think), instead of the normal red/orange. It works like a 20K-200K ohm resistor. !The diode can be working properly and sometimes change to bad! I think it may

There is no standard for a strain gage measurement of allowable deflection of a board or a fixture. It's possible that your fixture is causing the BGA cracking that you see. What protion of the BGA is cracking? If it is the solder connection, sear

Has anyone had experience with placing BGA on gold plated boards. I thought I read a while ago there was a problem with embrittlment causing cracked joints. If anyone has experience with this your feedback would be great. Mike
