Sal: If it�s not the PCB, what about the connector itself ? Is it from a different production lot with some unregularities ( dimensions, tolerances, pin alignment, material weakness)? How about handling, storage, shipping causes ? Could it be a tooli

hi. pascal your problem is mine. sorry. i have no experience about m/c for pihr. we use woman for stick pin ,sme connector after mounter. we also consider m/c just like you. what i want to let you know is that http://www.celtronix.com. bye

Hi Allan, I can�t help with literature on that topic but we have great success with solder thiefs to prevent bridging with 2mm pitch THT-connector. We added just blind pads of the same size at the end of each row similar to what you can do with SMD

Hi all, I'm would like to try intrusive reflow (pin in paste, paste in hole, etc.) on a connector using WS-609 solder paste (halide free, water-washable). I'm concerned about entrapped flux in the barrel of the solder joints. If there were to be e

The process is not that difficult so have a go as soon as possible. Take a board wipe some paste on a board stick the part in and run it through the reflow process. Don�t worry about balling just see what you get first, that what I did first ! The m

We are using press fit connector for some time without any particular visible problems, but still we need some kind of workmanship standard as a general guideline of what is wrong, acceptable and preferred levels for this job. Can someone direct me w

you can use IPC and Compact PCI standards for guideline then it depends on what kind of connector you want to pressfit. each supplier has its own design on pressfit pins like "needle eye", "baby H" etc... It is also importand to use proper equipement

Thank you, Mr Dave. Specifically, there are tiny balls spreading on the boards ( on top of solder resists, and not encapsulated). They are not near to any land/pad or connector. I do not think they post any electrical problem. They are quite far away
