Everything we do is RF and have had no problems in the last 7 years with - Indium NC-SMQ92J, Sn63 Pb 37, 90.25% Metal, -325+500 mesh. Stencils are always 0.005" thick. However I will qualify that by adding we are an OEM and each new product may requi

I'd tend to agree with what the others have said. Check the basics, board supports, setup, wiper paper working correctly. If it's a humidity issue, try taking some paste, place it on a chem wipe, and roll it around a bit, which removes some of the mo

We have not yet sent this out for analysis, So, I don't really know what it is. initial evaluation would lead me to believe that it is flux since it is only present on the solder joints themselves and nowhere else. I noticed that you also mentioned

The metioned process will work, but I do have 1 Question, How are the PTH comp. being inserted? If automated insertion is going to be used the process may have to change. Topside SMD - then Auto insert PTH, the reason for this, is depending on the p

I have used Quad/ Now Tyco since the early 90s starting with the 4c then on to the QSA-30s, APS-1, and now the Meridian 1010. We have six machines in a very small area and place over 10 million components per month. As others have said the service is

Hi there. I intend to do some evaluation between different pastes, stencils, stencil apertures and reflow profiles (to find practical differences, evaluate stencil suppliers and have some desing guides among other things). I'm considering to use ben

One thing I have done in the past although it may not be feasable in your case, is to process through normal reflow and then saturate parts with a high solids water soluble flux and re-reflow with hot air, iron, or even another pass through the oven.
