Hi, I am an EE/Programmer with a LOT of code for converting CAD files to MyData formats. I have existing code to generate Packages, Components, Trays, Board, Tray Type and Feeder files. There are a lot of CAD file formats out there, what do you n

Unless you have a feeder with unusual vibration that is generated during the advance it seems that the issue is packaging. Try another feeder that has been tuned up and properly lubed. Most high speed turret machines move the feeders back and forth a

Hi Fred Thanks for your advice. That can cause bcoz may be Machine Vibration also. I did not check whether the parts were already upside down before advance.I'll do it in next run. We found that other diodes,see atached pic, were no troble duri

very often toes on the QFP packages are exposed to base material and during time they oxidize. That is why you can have problem with solder fillet. Most important is heel fillet. Regarding your misalignment of IC if this is repeatable check your pl

I recently did a layout for a Freescale accelerometer and the mfg recommended pad layout did something similar. They where very specific in the pad layout dimensions. They stated the reason was "With the correct footprint, the packages will self-alig

We use exclusively pneumatic feeders and can NOT control the force or speed of advancement. We get a lot of components (mostly LED-type packages) that tend to flop around in the pocket a lot and are flipped on the side or “thrown” by the feeder duri

We had the same motor problem with our My12, whenever we would get the sound we would go through and slow down X accel speed in any packages and the placement accuracy as well. After doing this for quite a while we finally tried updating the motor c

Three ideas for you: 1) Make sure nozzle tips are clean. 2) Check coplanarity of leads to bottom of body. If leads are above body, it could be the are not contacting paste well. 3) Investigate static charge in the parts caused by the feeder or

The desiccant we've been using is going obsolete and that supplier's replacement options don't look like a good match. We'd been using material with a tyvek pouch. Replacements are either kraft paper or plastic. What is the industry spec that dete
