Steve What do you mean by better? More/less activity? fewer retouches? longer shelf life at ambient temperature? less hygroscopicity? longer open time on the stencil? easier to wash? easier to treat waste water? easier for washing machine maintenanc

| Dear all, | | We've got a curious problem. We have had a major problem with BGA's occasionally being placed one to several rows or columns off the pads. We are using Universal's GSM2 platform for our general purpose placements. Our Universal re

Never heard of the DRS-22C. I have had a DRS-22 for several years now. Purchased it when we started doing BGA's. The operators like it - good optics (split view), built like a tank, X-Y table easy to manipulate for alignment. I like it because I ca
