2 suggestions - Get a good scope - at least a 4X, but more like a 6X, 10X is best. You have a choice on used equipment for a substantial savings. A Leica Stereo 4 zoom is it. You can look for BGA scopes that have a 90` angle for looking at the balls

I use the exact same paste flux that we use in our solder paste for SMT manufacturing with great success. I have also had great success using the Air Vac DRS Hot Gas units with the same size BGA's. If to much heat is applied to fast to the BGA be it

Boy, I step out for a bit and everybody picks on me (just joking). I believe I may have been off base a bit. Checking every bit of your stencil design is very good - I do that too. I calculate LXWXH and reduce or over print where needed, depending

What methods do you guys use for maintaining lot and/or board traceability? When I worked in med. products, we used travelers that we recorded everything on, then serialized them at the end of the build. Not as effective as up front serialization,

Sure do. Spent a couple months with that group last winter trying to get the Soft Beam to solder a small connector board. It really depends on what you are trying to solder. The Soft Beam couldn't handle my job because our board was too small. No

Gee Ken, the old cart business must really be slow, I see you commenting on any old item in the forum in an attempt to hawk your carts and how they improve efficient factory operation. I have read your white paper and found it very entertaining to se

DaveF's request for more data of course is needed to be specific, but here are a few ideas and places to start. If the SMT line is causing the defects you need to identify where on the line the problem is being caused. What we see regularly is mish
