Hello, I would like to ask you if there is some formula how to calculate PTH hole and annual ring for pin in paste technology? Thank you. Mekmat.

Pin in paste connectors and lead-free questions

Yes, you need work with supplier to see if can run pin in paste for these connectors, even do some experiments. A step-up stencil would be good for these connectors, also connectors pin size and length match with PCB hole design.

Hey all! As background, I recently purchased a full SMT line for my company. We have a DEK 265, an assembleon opal xii, and a Heller 1500. Currently our jobs are leaded, and the heller is working perfectly. An upcoming job that we are potentially g

IPC 610 *C* states that the solder thickness requirement is a properly wetted termination is evident. Fillet height is another aspect and is usually specific to the package but is some function of solder thickness plus a percentage of lead height. D

"Gap" in completed solder joint between lead and pad

Wow, why all the anger? This gap you guys are talking about is measured as "G" in IPC/EIA J-STD-001 (Chunks was there, but she failed to read the fine print). And almost all parts that measure G follow Note 3 which states "Properly wetted fillet s

ICT Question, Via holes and Probes

Electronics Forum | Fri Apr 27 08:44:08 EDT 2007 | Brett

For those of you who use via holes as test points, and the via holes must be filled at the wave, is it necessary to have a "dome" on every single test point, or is it sufficient to have the via "filled" with solder? The ICT preson here insists that
