This has been our practice and its worked well: SMT process-QC/Touch-Up-Assembly. We have dedicated QC/T-Up after reflow trained under IPC requirements. They do the SMT inspection and ONLY touch-up if necessary. This way we never have to inspect SMT

Cookson solder paste 256 seem to be a good and very active no clean solder paste. We have some good experience. We did not bother to evaluate oters since we have had good results with this solder paste. May be you can try. Most important is the reflo

We use Alpha UP-78 (Older paste formula) and it works well for what we do. We standardized our stencils at 5mil with a 10% reduction on IC apetures and a home plate design on passive components. Additionally we use laser cut electro-polished stenci

You probably are aware of this, but somehow get the conditioning unit as close to the sensor as you can. It sounds like the problem is the "long twisted pair shielded cable". Try different means of shielding, connect the shield at the end that has

The Camalot Gemini II is capable of dots for 0402 chip. What would an Electrovert person know about that? With a 32gauge needle you can put down as small as 0.006" dia dot. For information about dots for 0402 chips, please contact Camalot application

Russ, I tried to get a screen for glue but the design engineer who laid this board out made up his own rules. The 0402 pads are to close for a proper dot size.....per the stencil house. That is why I am going the solder mask route. I would rather

Is anybody using via-in-pad under a BGA successfully? Is this a specialized capability, or do most board houses have the capability to do micro-via's? How small does the via need to be in order to avoid solder wicking? I understand that in order for

Via in pad can have any size hole, but you're correct. The larger the hole, the more solder that is scavenged from the solder connection. We believe that a proper via in pad design will either: * Move the via to the edge of the pad and cover the vi
