Hello, all, I have been having problems with bent push rods on my Philips CSM84. I have caught it a couple times when it happened, but it happens so fast I still don't know exactly what the sequence is that causes this. The push rod is clipping a

Unless those vias are used for ICT or test.

Yes, I have tested some boards, and found that most QFPs which near the via will have the higher temperature. One of my customer requirement is to have the temp less than 200 deg C for top side. We were using the hi temp wire to solder the QFP's for

Hello Reese, We currently own two MIRTEC MV-3 desktop machines and one MV-7 inline machine (so you can tell right away that I am a little biased.) We had an opportunity to evaluate both the YESTech and MIRTEC machines on our production floor. The

I want to ascertain the oven profile required for through hole connectors with solder pre-forms. I need to get double sided PCB�s made for that purpose. What is the best way to get these PCB�s made to simulate real world conditions?. Should I leave a

I have been using ICT for a number of years. It is still a viable resource for catching defects in the production process. AOI doesn't catch everything, such as bridging on QFN or J-lead devices (this will depend on the type of AOI and camera syste

Test Jet will work for catching lifted leads, certainly. X-ray is the only thing for testing for internal solder defects such as voids and cracks. I personally do not have any experience using X-ray, so I cannot advise on its reliability. Perhaps

Not as such. Generally, people tailor their profiles to produce glam solder connections on their boards. Search the fine SMTnet Archives for discussion on the factors affecting solder reflow recipes. What is the best way to get these PCB made to s

This looks like it may be a good application for an Air-Vac or Wenesco type solder station. It is a solder pot that has a small motor to pump solder up through a chimney. You can put different nozzles on the top of the chimney, so you only apply sold

We've seen a number of 0603 parts not being marked, more and more often in the market. Unfortunately, we never narrowed it down to whether or not it was manufacturer related, or separate product lines within a single manufacturer that were available
