SMT line expansion - new oven and selective solder

Electronics Forum | Tue Feb 25 16:45:45 EST 2020 | stephendo

One thing that you do not want to do is run a 240V oven at 220V. One place I worked a few lifetimes ago had an oven that had five top zones and only two on the ends on the bottom. It was something like 440V but supplied with 408V. It took a long long

CSP and underfill

Electronics Forum | Fri Aug 23 18:51:00 EDT 2002 | edahi

weve done a few evaluations for the no-flow underfill and for the reliability I think it has already passed MRT L3 @ 220C reflow. What is it specifically you're interested about the flow u/fill??

lead free and tombstoning

Electronics Forum | Fri Feb 17 11:01:47 EST 2006 | amol_kane

with lead-free solders, one would expect to find less instances of tombstoning. this is because SAC alloys are not eutectic and melt over a range of temp (usually 217-220 deg C) instead of at a single temperature. therefore the forces due to solder s

Stencil cleanliness and inspection

Kerryn, It's the first time I hear someone who needs an automated inspection machine to check the cleanliness of stencils. Why not improve on the cleaning method itself. I use ultrasonic batch cleaner. It takes 3 minutes to clean a stencil, 2 minutes

We use CircuitCam extensively, but not for MYDATA. What exactly is the issue you are seeing? Do you have the MYDATA Export module from Aegis?

We unfortunately use GERBER data to digitize boards more than any CAD. We are CM and many of our customers do not provide CAD. With some Legacy products, we still use 274-D Gerbers.
