We are in the process of establishing a design for thief pad associated with SOIC on the bottom of our assemblies. We are seek advice on design and alternative to their use. Best Regards, Charlie

What machine are you using to place the components? I assume that you have checked placement prior to the refow process?

We are using a glue and wave solder process for primarily chip components. Our products do not use any fine pitch components. What would an acceptable benchmark for the placement defect rate be? 50 DPMO? 100 DPMO? 200 DPMO? Thanks in advance,

I've got a process run amok, really thick skin, and a little bit of knowledge. Now you REALLY oughta be shakin' in your boots.

It is okay to use OA flux if you have a very robust cleaning process. lots of water and saponafier are good things. No-Clean is much safer when it comes to reliability. I personally like the Indium no-clean products. Russ

Hi All, We are in the process of converting from RMA solder paste to no-clean process across the shop. This will allow me to carry my semi-aqueous cleaner out of the building and set it ablaze using the terpenes as the fire water. Then I can go ab

It was the wave process, Just thought I'd let everyone know for future reference. Partial reflow at selected leads I am now aware that 63/37 does indeed have "a slushy zone" that I thought was not possible. Russ

I thought the stencil was flush to the top of the board when Screen printing. When does this snap off occur in the screen printing process?

Hey everyone, Does anyone out there use a solder paste height measuring system ? I would like to know what the standard is for paste height compared to stencil thickness and how you use it as a process tool. I appreciate any help. Thanks, Steve.

Hi Cory, As a manufacturer of aqueous cleaning systems, my advise is somewhat biased, however I believe it to be accurate. We have hundreds of customers who have implemented no-clean programs. The programs have been successful when measuring the r
