Does anyone have experience with placing heat sinks on BGAs? I have limited experience with PSA (pressure sensitive adhesives)heat sinks, and am interested with the possibility of a clip-on device. I am specifically concerned with ease of assembly

Hello all! Recently we got a problem about the Funtional test. Some boards passed tests by using the auto-fixture(vacuum), but failed by using manual test fixture(need to plug CPU, DIMM etc.). The error symptom is no picture. We doubt it's the proble

Can anyone please help me locate details on maximum allowable temperatures of components when passing through a reflow oven. I think I want the thermal profile for the part, or a source or standard which will allow me to check if I can safely reflo

I need to perform shear tests on components that have been glued prior to wave soldering. Can any one recommend a shear tester and some standardized info on testing? We have had problems with poor glue bonds and would like to implement a test metho

we have just started wave soldering passive SMT components and through hole. We are having trouble with voids on the SMT components. It is very random, but effects a lot of TSOT's. We are using an electrovert with a chip wave. Are there any obvio

Hi All, I'm getting an Electrovert Wave. It's the replacement for the Econopak. I can't remember the name. Either way, the spray fluxer is made by USI. Does anyone have experience with this spray fluxer. Good or bad would be appreciated. Thanks

Looking at the full convection reflow oven market, I see two segments, high mass heater ovens (i.e. Electrovert Omniflow,...), and low mass heater ovens (i.e. Heller,...) Did some of you guys did some testing on both types and what were your findings
