A good set of fixtures are what you need to get it done right. Since we are in the same area, I would recommend give ATD (Advance Tooling Design)a try, they located in San Jose. We been using fixtures from them for years. We build thousands of Fle

Hi Thomas, Thank you for your advice. BTW, unfortunately, I received negative answer from the Fixture house same as below. =========== We have an issue here. Your board is too thin. It is fine to make the fixture for first side. But when you run

Hello : Some of the recent FBGA (a Chip Scale Package) packages that I am looking into have body sizes having aspect ratio's 2:1. In particular, body sizes of 14x8mm, 15x8 mm etc. The ball count for this particular package is around 40-68 I/Os. My qu

I would always recommend that an oven be used. I am not familiar with the ERSA rework system so I cannot comment. The key is to heat evenly with the correct ramp rate. If your rework station does this well then use it. if not I would put through t

Based on your knowledge and experience, could you tell me about speed differences when placing a mix of SMD at mass production? We could consider packages like the small R & C chips, then SOD323, SOT-23, SOT-23-5, SOT23-6, SON6, QFN8, SOIC-8, SOIC-16

I am trying to make a PCB populated with complex components such as LGA, WLBGA, LGFP, LFCSP, VFBGA, QFN, FBGA, PBGA so that we can test out some PnP machines. I have found parts on digikey for each of the packages we want to test but trying to make

All SM machines pick components with a vacuum nozzle. Most likely the component is picked in the geometric center, which may not be the center of gravity ( SOT 23, SO 89 ). Any other pick position than the center may be taught upon requirement, but y
