Settting up conveyors for a SMT line....

Electronics Forum | Wed Feb 12 17:10:02 EST 2003 | Mike G

Most conveyors are sold by the inch. I allow for no more than one inch gap between the end of the conveyor and the next piece of equipment. If you trust your measurements, 1/2 inch is best. This will allow for the smoothest transfer possible of small

First, there is no standard. Next, on one hand, most BGA cost a lot of money. On the other hand, choosing to use reballed BGA in products for shipment depends on how well you expect to meet your customers' expectations about product reliability wit

We just got Red-E-Set from Production Solutions for our DEK ELA printer. It is a similar concept, it's mechanical instead of hydralic or pnumatic. The print results are very good and the operators love how easy they are to setup. I am planning on
