We're looking for a contractor who can support high volume production of 0201 passives and 1-2mm csp's to create 4mm sq. RF modules as well as mold cap capabilities. Any leads would appreciated.

It's a four-spindle head. I've already learned the joys of the size of the nozzles...on a job that had an 0603 cap a bit too close to an SOIC. The first panel ran, and the cap placed after the IC...and I had parts everywhere. Got it figured out an

Hi Todd, This is Jason, I wrote you re the Dek, MPM and Heller. We set-up an EMS company in Su Zhou, China and looking for some contracts now. Please send additional details on scope of project to my email (you know) if willing to contract us out

Morning all. So today I have been tasked with conformally coating a few of our first run PCBs for a new product line. The problem is that they have already had all the larger caps potted with RTV. Are there any problems with spraying the CC over the

If you apply the RTV after coating, what happens to bond strength since you are now bonding to the coating and not the board? Will the caps still survive vibration and shock? I specify applying RTV before coating for this reason. Am I correct? I als

We understand the problem of trying to coat over RTV. We have seen the same problem with acrylic and urethane coatings not wanting to stick to RTV. Some acrylics seem to be worse than urethane. Since this is a new product, may be you could pot your

For now, on this first board, we will be reworking components such as 0805 and 1210 size caps and resistors, along with SOT-23 and SC-70 size packages. We might eventually get into BGAs. This board will most likely be a double-sided board, probably

For package shapes/names I would recommend using manufacturer names. This is much safer than coming up with descriptive names like QFN32_5x5 as there are multiple 5mm 32Pin QFN shapes even when pitch is the same, this makes it safer to use a name in

Earl, et al, Boy things get old and cold around here fast. I promised more detail on my capactior problem and I thought I could drop something completely different in the same message and tell a tale of solder balls. First the caps. We still have

I'm with Steve and flying probing. As long as you are testing the capacitance of the cap in the circuit and not of the cap itself you'll get a pretty good indication. Most are going to be 10nf and 100nf decoupling caps at that size so quite easy to
