Graceyt, I know you are being shot a lot of info. Have you gotten any resolution to this problem? I've seen similar problems in our thermal chamber with Demodulation units. The IC, in the module, inside the radio inside the chamber at the top of ou

| I am currently involved in a reliability project related to SMT QFP and TSSOP fine pitch solder joint reliability. I have decided to use a temp chamber for stress testing. Is there a test standard that covers this? I am also a bit unsre as to wheth

Hi Kevin, Sorry for the delay in responding to your question. I have been trapped in Australia (not a bad place to be trapped I may add). The scale in your cleaner is not usually caused by the chemical used in the wash cycle (although Armakleen ha

That was the case with your oven but it is not so with ours. First, the distance from walls of the inner chamber to the product differs from one oven to another. Second, the dissipation of heat from metal heats up the air in the oven which in turn h
