Good to hear, thanks for the response. Once you get the program fine tuned, do you generally have most boards that are inspected pass with the green good screen or do you generally have to review a few defects? OF course this all depends on passing r

Are you doing this to minimize solder paste splattering? Is this a value that you use for all QFN's (would the overall size of a QFN matter)? I was told reducing placement force with these components is recommended so just was wondering what is bein

If anyone still disagrees with you point, out that the "of each" refers to individual pads. If the 95% refered to 95% of the pads it would not have said "of each". Also someone correct me if I'm wrong but isn't this standard to do with solderabilit

I am interested in performing SMT Assembly on flex boards that would be a couple of inches wide but 2 to 5 feet long. Obviously quite a challenge. I would like to hear from anyone that may have seen anything similar done, or at least has an idea of h

We've used masking tape and peelable (pink) mask to mask our boards before conformal coating for a long, long time. This is a huge time sink, and increases our lead times (particularly because of the cure time for the pink mask). What are other com

Hello, I have an issue with SOD 923 out of the oven. The part looks grainy, doesn't show a good wetting and looks like it has to be touched up. Everything on the board looks beautiful except this part. I tried with the profile, I checked the pad des

There is no easy way... but this is how I do it.. Origin the R axis, losen the idler bearings on the belt, remove the C clips at the top of the heads, lift up and remove the spindle assemblies being careful not to lose the 2 balls in the side of the

Hola After some investigation I found that these units have this oxide after reflow, so I'm guessing that may be some process related issue, I'm attaching pictures for reference. My supplier has not given me any explanation so far, they are working

Looking for advice on soldering lead free paste to a board with very heavy gold plating. I have learned from the Customer that this is HARD GOLD and that it is 10-20 Micro Inches Hard Gold over 100 Micro inches of Nickel. When we reflowed the solde

Hi Eric, your problem looks like a printing issue - if the part(or group of leads) missing solder is always the same. I would say you should check: 1. Stencil for any damage at this area 2. Squegee for damages 3. Adequate pin support un der the boa
