Interesting. I'd start with the "Help Desk" at the Reliability Analysis Center [http://rac.iitri.org/]. Please get back with your findings.

Have you done any analysis on the failed rework? There could be any one of several reasons, i.e. bad alignment, wrong reflow profile, bad pad plating, etc. More information will help us help you.

Susan, If you are not doing design then your warranty must state that it's only for "workmanship". This excludes failures resulting from design or materials. In the event of an issue concerning product failure in the field have an independant labora

Continuing with Steve's comments, the true measure of whether or not residues [NC or not] are good or bad is found in the results of an laboratory analysis of the residues and an assessment of the impact of that level of residue.

Does the thermal conductivity of a copper trace on a printed circuit board change as the copper oxidizes? Is the oxide on copper a thermal insulator? If so, should it be considered in an analysis of thermal resitivity between a ground plane and a h

Depends on the size, complexity, quantity, and density of the board. Also depends on the CM and lead time required... Choose 2 or 3 good CMs and send them a pcb for analysis and quote...

Anyone have information on the ROSA Technique? It is a derivative of the SERA analysis for solder-ability on pads, (they are not italian sisters)I belive the techniques were developed by Rockwell and Motorola. thanks in advance. JKK

I have a COB device that I need to decapsulate for failure analysis. I would like to find out how I can do it using common materials/process that I can easily find. Thank you and I look forward to hearing from you soon.

I would like to know if there are any standard guidelines for the development of Process Failure Mode and Effect Analysis. If there is can you refer me to the source. I would also like to be referred to any source relating to current developments in
