Hi Everyone, Just wondering out loud, what type of inspection stations do you guys have for post re-flow? Currently we are using just a bare bones visual station. Is there any recommended station that works well? Or is it just a "whatever fits" kind

I do not recommend ever leaving the top of a via-in-pad open. Cap the via in the pad. Leaving it open for "solder to stuff the hole" causes issues in assembly, notably insufficient solder due to vampirism (the solder wicks into the via, rather than

If it is important to have vias within thermal pads to help dissipate heat i would recommend using solder mask to stop the solder from wicking down the holes and resulting in insufficient solder. Some further info can be found here:- http://www.surf

We use a few different style of press fit connectors, terminals, studs, etc. We use a tabletop arbor press for most everything we do, but a lot of times we will see some measling or slight delamination around the holes for the press fit part. Is ther

I had some of these before and they do a decent job. Laser alignment is ok for passive components. Compared to vision systems it has mainly disadvantages. If you have bended lead on IC for example, it wouldn;t catch it and it will place the part. I w

We are using a nitrogen generator (with a N2 storage tank) that feeds 1 selective solder machine. I do not know which type of generator it is. The N2 generator has an oxygen analyzer on it. The selective solder manufacturer recommends a N2 purity

We were using TL1240Y Tack switches for 2 layered PCB and posted those switches by hand. Now planning to re-spin PCA where we recommend that part to be added on SMT process. So looking for a better and opt switch with same specs. Please suggest me an

What is the maximum PCB shelf life for double side PCBs after first reflow? I mean, after assembly bottom side, how long can I keep the PCB without solder paste waiting for the second reflow? (Considering exposure on production environment conditions

I was curious what others in pcb assembly are doing as far as profiling. Is profiling an important part of the smt process? Should every board type processed be profiled to determine optimum oven temps per paste recommendations.Is it ok to assume tha
