Thank you. We are testing new components and running into some trouble. We have a copper component with indium alloy solder, soldered to a silver surface. This is then run through a temp. shock test of -40C to +90C, and then humidity chambered at 95%RH. 3 questions: Is the intermetallic...
Can any of you folks tell me what conditions would cause an intermetallic bewteen copper and indduim? Temperature, humidity, etc.. What about indium and brass? Also, how to prevent it?
Thanks, Alex.
