Grant, Thanks for sharing that experience with us; this comes to show what damage can be done when politicians make laws based on rumors instead of facts. New laws as drastic as removing lead in soft soldering should have been based on scientific e

Let's face it guys...in most cases (stress the MOST!) a typical FR4 board will do the job. Few layers, low copper, not too densly populated etc...no worries. Use a reflow profile which avoids the 245-250C range, use a shorter TAL, Viola you have a go

Help! Since last Friday i have been having issues with a Quad qsv-1, it all started with a quad align error, i found there to be a small quantity of grease covering the lenses on both quad align sensors. I wiped the grease off and then everything s

I have been trying to eliminate the troublesome tubed parts in our SMT process but because we are a high mix/low-medium volume we still have to deal with it sometimes. However, the ones I can fix I'm working on. The next step in my war against tubes

Greetings everyone. We are currently doing some experimentation with solder paste printing over ground planes. In this application, the entire perimeter of the PCB is a ground plane. It's about 4mm wide and wraps around the whole PCB; There is no so

A couple years back we were looking at going to an enclosed solder paste printing process, similar to the ProFlow, Crossflow, or Rheometric Pump. We have older MPM AP25's with a custom transport. Speedline told us that in order to add the RheoPump,

Hmm, interesting. My Philips CSM84 weighs 1600 Lbs or so, and it bounces around quite a bit when moving. It doesn't really move very fast, maybe 2 M/sec tops, and 3600 CPH is about all you really get unless the feeder is right across from the compo

Well, when facts and data become "complaining' and "scare-tactics", it's pointless to carry on a conversation. You might as well twist tin whiskers so that it becomes a GOOD thing. "Just say YES and we'll move on!" http://www.funnyordie.com/vide
