First clean and de-bur the hole in the nozzle, then try it again. If the Head does not pick up at the feeder, then moves to the dump position...it means that the Vacuum Sensor Board has detected that the nozzle vacuum is above the LOW threshold setti

I would agree with the advice given by previous poster's. "Buyer Beware" is the rule of the day. Especially when dealing with 3rd. party brokers. Keep an eye out for some of the teir 1 EMS corp's auctions. You can pick up some excellent deals on we

That would be great Armando, thanks. Also, what changes might I make with metal clad light boards (LED). heat transference is tricky with these and the solder is not wetting well.

If you're still having this problem, talk to Al at MyData about replacing the ribbon cable that is wrapped inside the head, and connected to the two LED's. It's a bit of a pain to replace this cable, but, it did fix the problem for us. The other po

Bottom line is to stay away from attempting to sequence different part number in the same reel. You are asking for trouble with this approach. Work on operator training, efficiencies and organization. Best of Luck, Shawn

Yes, this is a good point and really only time will tell just how reliable such a machine becomes. What I'm aiming for is to simplify and reduce the number of sub-assemblies. For example we are building the camera/vision processor and lighting into

I am planning to purchase a pick and place this month, does anyone have experience or heard anything about the TWS Quadra pick and place? The unit I am looking at is preowned, it has around 100 feeders, and it is selling for around $11k. The boards

Unfortunately, smt machines are not like TH sequencers. But, that is in their favor. Multiple reels, multiple part types, many positions = very flexible. Offline setup is paramount to line utilization. Remember, you only make money when the machi

Anything that can handle the standard SMT packages of today has to be precision. The machines have to be built rigid, and cannot be made of sub-standard components. I have worked with placement machines since the late 80's. The machines that work th

If I understand correctly you want to pick BGAs from the ball side using some type of vacuum arrangement. You will find that the reliability of this is dependant on the size of the balls and the pitch. The larger the balls and tighter the pitch, th
