I had no idea what this thread would result in.... But, since we are on the "made in China" kick... There is serious immitation going on, that is true. But that will not be the case long term. There are already companies innovating, there is techn

You are cooling too fast, and some flux and paste is worse than others... Can you control your cooling zones? Water Temp (higher)? Or Water Flow (less, effectively less cooling)? Changing water temp is prefferable over flow if you can do it. I h

Patrick, Have you seen Al Gore's documentary on Global Warming, "The Inconvenient Truth?" It was okay, but I didn't like how Gore got political in a few scenes by slamming the current administration's environmental policies (or lack thereof...c'mo

Hi Samir, I did a lot of thinking about global warming the last 3 weeks and more weeks to come. I live in Texas and temperatures this time of the year normally are between 50 and 60F, the last 3 weeks we have been in a deep freeze with snow, sleet a

We are an OEM and we were about 75% converted to lead free. Very few of our customers showed any interest in ROHS compliant products and none of our competitors were doing it either. We had a few field failures that may have been related to the hig

Made no changes to pip process for lead free. Everything stayed the same. just have to ensure that components can withstand the high reflow temp. incomplete hole fill is from aperture not being big enough. Many people forget that paste reduces in

Solder preforms can be used in SMT assembly for through-hole pin-in-paste process. In this process and modified aperture is used to print the paste with standard stencil printing, then a solder preform is picked and placed by a machine into the solde

Good morning, The critical points for successful PIP technology are: 1. Gap between THT lead and PHT hole. It shouldn�t be greater that 0.2mm; 2. Lead shape. THT leads MUST be straight or you�ll get excessive voiding otherwise; 3. As Russ said, pas

Flux drop in lead free process

I am seeing a problem of flux droping on the PCBA during reflow. This is a pb free process and I am using KOKI pb free paste with 8 zone (and some 9 zone) reflow ovens. Line throughput is about 10,000 boards/24 hours. I suspect that the exhaust is no
