The boards were just a little larger than a SOT8. IIRC we had a pizza slicer type depanelizer and it wasn't too bad. We just did enough to populate the bare PCBs we had. Where I am now a customer has us put a QFP and a few other parts on a SOW28 f

We are also a medium volume, high mix contract manufacture, last year we purchased a MYDATA MY12 with Linescan and Hydra. It is a great machine. We had a MultiTroniKs before but it was not as good as the MY-12. The MYDATA will do everything and do

Hello Phil, sorry for the confusion, because of our level of defect control and tracking at each process step, we did not use AOI systems at the time. We had a manual inspection station after reflow, then ICT and Functional/Final test for each produc

Yes, I can see your problem, the nozzle makes only good contact in the center and so the ends don't make good contact. The ends tend to curl up during reflow. There were two suggestions to solve this. 1) Let the operator push down the labels befor

The first thing that I would do is contact the smock manufacturer and ask them for advice on testing the smocks. ESD FROM A TO Z 2nd ed. (Kolyer) states that: smocks should have a resistivity of less than 10^12/sq and must not shed steel fibers.

Look into a used Siemens F-4 or F-5. These machines can be had for a reasonable cost, they are easy to maintain, the footprint is small (7' X 7.5') and they are simple to program. These machines have a 12 nozzle "Star" revolving placement head for

TP9 machines are good, but old machines. We ran a TP9 for many years. As the machine got older it required more and more maintenance and had more frequent small issues similar to what you are seeing. We only saw 1 of your 4 issues specifically whi

Is there anything stopping you from replacing the flat belt solution to a continuous running steel roller chain conveyor? - From there (depending upon board temperature) you should be able to buffer your boards in a vertical buffer station if neede
