Hello phil, The use of AOI systems give us the opportunity to auto-collect defect information much the way you're using them now. AOI systems become extremely effective when the collected data is used to perform some positive change into the process.

First, what would you define as semi-automatic? For SMT production you might need a screen printer (these can be anything from full manual to full auto. The low end printers manual require each board to be aligned with a piece of mylar prior to p

Hombre, presuming you are doing this as enhancement for looks, I have some comments. 1. LED's seldom run on more than 3 volts. 4.5 volts max for some special types. Because the car is 12 volts all over, you have to use a resistor to reduce the v

At least the few people left in this industry should make a stink, why all these jobs went to China and take efforts to get them back. If I take a typical line, which can do 20,000 components an hour, costs $ 200,000, a board with 50 different compon

Hi, I used to run a clean room, and it's right, most of the dust is created internally. You will need to add some HEPA filtering to the area, and an air handling unit that can control temp and humidity as well to get correct environmental control.
