Contamination of components

Electronics Forum | Mon Feb 26 09:35:48 EST 2001 | larryk

With allocation of components becoming a bigger and bigger problem, our company has had to purchase components from brokers. Because of this, I've found an increase of component contamination. What I mean is I have found problems with oxidation of th

Dave, We use water soluble flux. We currently do not do a solderability test on incoming components, I'm thinking that this is going to be a "must do" with these components. Larry

We test Parts and Components to IPC J-std-002/003. We also use a wetting Balance tester to determine solderability. We also test with SERA. We use ROSA to electrochemically revert the components back to their original state. Need more info ... email

We feel that we get more than our share of crusty components, but we just smile because we�re so happy ["Happy, happy" as Emeril says] that we use a nice and hot, aqueous flux. What kind of flux do you use?

Hello, Could any body direct me to guidelines describing the best practices for rework of perimeter array components (such at SOIC's and QFP's) or may be share your opinion of the best approach to do this? Thanx, AMS

What is the expected of soldering chip inductors directly over chip capacitors. What is the expected life reduction in the field and what could be done to minimize it ?
