Hello, I am Philip Kazmierowicz and I work with KIC, a Thermal Profiling company. We have done many lifetime experiments on Printed Circuit Boards over the years. The key thing to understand is that if the primary material of the board in FR4 fiber

I'm shadowing an old posting posted by Odor back in March 2002. Any Expert out there, if you have good answer to the below questions, please dive in...Thanks in advance. 1) Does anybody have done the profiling board life time experiment? 2) The prof

If all your doing is trying to measure oven repeatability, but then you wanna do it a bunch of times, have a profiling "board" constructed out of say... delmat, delrin, or some other glastic-type pallet material. Have the T/C's permanently fastene

Hey guys and gals: Didn't we have a thread on a topic similar to this recently? Didn't someone from one of the profiler supplier companies post the results of some study that they performed? We can't find it in the fine SMTnet Archives. Unfortunatel

Hello, the colleagues are all right. What I did in addition to show customers and quality that we either need or dont need a stencil: 1. Made a procedure - in there i defined 50 000 cycles and then the stencil has to be checked by me. In the checks

Hey man, can you please suggest what you do for traceability system to count cycles of the stencil. Is there any special setup for that or just a Excel sheet with formulas.?

Never heard of any traceability requirements for stencil cycles. The SPI machine should be the judge of how your print process is performing.

Traceability can be made for many things. It is up to the factory and what it wants to implement. You can have traceability on the stencil for a several reasons: 1. Want to check stencil cycles 2. Want to verify if stencil is the correct one loaded 3
