I am looking for someone who has knowledge on the operation of a Quad 100. I want to bring that person in on a contract basis to train my staff. My facility is located near Edmonton, Alberta so ideally the right person would be in the western Canad

Again, I really appreciate the valuable input you all provided. Got my Air-Vac SRM4 machine Friday afternoon. Stored it safely in my cube over the week-end for safe keeping. Tried to find 220V single phase next to air with no luck yesterday. Electric

Hi, I currently work on SMT department to uptimize all process. I've just selected the solder paste after testing 15 different products. To be able to do that, I had to create a procedure to evaluate each paste and to be sure that my profil was per

First, skewing is a perfectly acceptable condition, providing the amount of skewing is not excessive. A-610 provides guidance. Second, this part is a land grid device. Land grid devices [ie, BCC�, LGA, QFN, MicroLeadFrame�, etc] are essentially BGA

Hi, I have a soldering problem with a header SMT straight single row of 8 pins. It's a samtec #TSM-108-03-T-SV-P (P&P). The first problem I have is an allignement one. I do not use alignement pin for now but I expect to use it. Concerning solder

As I was explaining in my thread, the things that you have to look for when buying an AOI is the false calls rate (which you described perfectly) vis a vis the money and time you want to spend. We bought our machine after that we evaluated some. As y

Higher Tg values are only one thing to look out for. Two other things that are very important to watch are the Td or Decomposition Temperature (the temperature that the epoxy actualy starts to break down), and the CTE for the material. Some Tg 14

Solder paste thickness control is more important in SMT process. What controls do you have? I guess if everyone follows the critical control path, then there are always reduced problems. The issue is no one is perfect. Paste tends to be on the stenci

Hi D0m0 Can you standardize on your temps and just adjust conveyor speeds for various sizes of the boards? Another trick is to parallel t-couple plug off the actual t-couples of the oven and mount the plug in an easy access point of the oven. The

You will need to develop your reflow profile which includes drilling a hole through the fab and into the ball for accurate temp measure. During profile/process development you will probably want 3D x-ray (consider contracting that out). Once in prod
