Joe, You would be best off going with a larger company such as Universal or Mydata at this point. The market is still bad and this is where you will get your best deals. They offer better support than a small company. Small companies like Contact sys

To my point of view, you should be aware of some issues. Manual taping machines with a foot switch for tape advancement require quite a few adjustments before you start the job, like: Tape width adjustment, component rail adjustment, pitch setting,

Hi Patrick, I can easily troubleshoot ML, EL and SL 20 systems by phone or e-mail, but the MPC-29 is a bit more complex. The problem that you are describing was failry common, and there were a number of potential causes. First is to check if the dr

As someone who has worked for a contract manufacturer in China, I can tell you that regaining manufacturing jobs in the US will be a difficult task. Difficult, but not impossible. Many companies are discovering that manufacturing has only ONE advanta

Human resources or head-hunters may not ask these questions either. However, there are other ways to find out, if the applicant is fit for the job. I must admit, that raised with a different cultural background, it was particular difficult for me to

We're not familiar with the AUG5 from Taiyo. [It doesn't show on their US site.] Is it liquid photoimageable? Printed solder masks are more likely to bleed. But you wouldn't have any solderability with bleed. Your plating seems acceptable [if th

So if I get this right, your customer wants you to run this product as pb free even though it is not. In order to run this as pb free you need to run pb free paste. If you use 63/37 paste at the higher temps I believe that in addition to the compon

Ken you say reaching 218 to 221 C will give a homogenus solder ball. The pb free solder balls on the BGA reflow at 235 C to 238 C but I have seen when you combin to differnt types of solder say 63-37 and 10-90 you will atually lower the melting point
