If you want to do this process, you should ask how to design the board for this process. Regular hole dimensions in the board will not work for this process.

Frankly it's not a good process for large connectors. Messes up your screen printer and you get min acceptable solder joints, if that. Select solder is the way to go, especially with all the smaller units out there.

Real Chunks: Do you think a 28-pin connector is too large? For us, it's all about the number of rows. One or two rows are no big whoop. Three rows and greater, now that's when it gets messier.

this is a two row connector that I'm talking about. We were going to select solder it or wave it but we are just trying to make the process faster and if I can get this to work, it will definitely save time for us.

With two rows, you can overprint to the outside to make up the solder volume. It's when you have rows in the middle that things get tough. A good stencil house should already have overprint libraries for this.

Hi, Is depend on the size, you may also able to using different type of solderpaste to accomdate instead on PCB. Hun

Does anyone know where to get rebuild kits for CP6 spool valves? We want to re-build them ourselves.

Hi, I was wondering if any of you operators/users have experienced any reflow solderability issues with any of the ATMEL QFP components with in the last three months. Leaded or lead free processes?

hi, we use pump print stencil and have problem with cleaning.we clean the stencil handling, using zestron301, but in the holes stay adhesive.Take a test with ultrasonic cleaner but resalt is not good.
