Samir, From experience, the only board test situation where tented via's have difficulty with contact is with a Flying Probe type tester. Otherwise, for traditional ICT, the force of the pogo pins, correct probe type, and fixture design should do th

You're a piece of work! Why don't you work for any of the major wave companies? So how does slowing the conveyor speed eliminate drying flux? And when you slow it down, what speeds it up to make you say "I lower the wave because I get shorts going

Which model Yamhah are you talking about and what is the make and model # of the manifold block for the micro ejectors? If it has the Koganei ME05M series then your local rep can supply the filters. It is a good idea to get spare O-rings for the filt

Will the Pb part handle 240C? That is the first question that you need to answer. If it will then yes I would run the pbfree paste and profile. I assume that all other components are pbfree. If not, the same questions will need be asked as for th

Get the manual from the tool that you will convert the GERBER data with. Get familiar with the different types of GERBER (274X or 274D). 274X has the aperture data loaded inside of it. 274D you will require an aperture list (separate text file to loa

Get a book on effective complaining. Gerbers is not a good way to program. Matching up the designators is but one headache. At the very least try and get centroid data. But try for ascii cad files. Are there any programs that generate gerbers but ca
