Dear all, Is there anyone who has the experience in conducting Push&Pull test for fine pitch components?i.e.SOIC,QFP. The customer clearly stated that,"every lead should be tested for selected components".but, you know that,the fine pitch,0.5 or

Dave, you are right you would expect the soldermask to be higher than all SMT pads on the pcb if it is higher on the fine pitch components, but the other areas of the board do not concern me as much as the fine pitch areas. The pads on all the other

My stencil thickness is 6 mil and we got qfp's with fine pitch. how many percent should i reduce my stencil aperture using a 6 mil stencil for 0.5 mm pitch and 0.4 mm pitch ? thanks

I am interested to know what people prefer for fine pitch packaging. Tape/Reel or Waffle tray for .031", .025", .020", .015" pitch components? What is the most robust packaging (i.e. fewer bent leads, etc.) Chuck

Is there a chart available to use in identifying the pitch of fine pitch components - one with which a components leads could be matched ( similar to that of the component's "footprint" on the pcb ) ?

SAG: Questions on solder mask webbing with fine pitch parts are: * What is the minimum pitch that you can use webbing between fine pitch pads? * What solder mask do you use?

Hi We did some evaluation to solder 0.4mm pitch by Wave. We found that there were many solder shorts at Sockets pins so it made touch up time longer. Please advise me someone has achieved the fine pitch soldering by wave. Thanks in advance.

Fine pitch parts are not the issue. Platic parts that absorb moisture are the issue. Search the fine SMTnet Archives to get started. Try: * MSD * Moisture sentive device * Dessicant cabinets * Baking times * 033 * 020 * etc

What is the QFP pitch ? What aperture dimensions have you chosen ? Is the stencil laser cut then polished ? Your AFTER stencil size looks promising...your BEFORE stencil aperture size looks disastrous...would surely give bridges.. Your pcb pad siz
