John, Universal has a smaller footprint HSP chipshooter, I believe the 4795S and the 4796R that takeup a lot less space than the full sized chipshooters do. I have a 4795S, it's just as reliable as our full sized 4795's & 96's. As far as BGA's I pr

Dear Dave, Sure we can ! There are two values going around. One is 50 mg/mm2 The other one is 30 g/inch2 (30 * 1000) / (25.4 * 25.4) = 46.5 mg/mm2 So we are talking the same language. Regards, Frank J. de Klein | | | Hi, | | | We have encountered one

Quad4C's have their moments. If the price is right and you are aware of the machines limitations then you will be satisfied. The placement rate is slow, 1.2 seconds/chip. Don't buy any Quad if it has the CyberOptics Laser unit, the Quadalign unit is

At one time I could show you the spacing of the chain of an electrovert but the burn marks have dissapeared. The center support chain would wrap around and jam up and with boards in the oven.............. On that one for some reason we bought it wit
