Screen Printing Adhesive on Mixed Technology Boards

Dave, How do you try to contol the glue release? The information we've gathered so far indicates that this is controlled by the speed and distance of stencil separation. How do your defect levels compare to dispensed products? Thanks again, John

Printing Problem

Electronics Forum | Mon Nov 22 05:22:29 EST 2004 | Rob

Hi Harry, We had some of the ECU's, but all they are is a heater & a chiller, and the controller turns on whichever one is required. Unfortunately the contollers were pants so our lab made their own. Rob.

Yep, but its hard to contol small parts with the bags. They're good for DIP's and sockets, connectors, but radials are kinda hit and miss. I bought mine from Pentagon EMS. They only use the finest european leather (kidding). PENTAGON EMS 10950 SW

Mike: You're correct, but in better shops there are guys with little black books in their back pocket. They know how to contol their variables and give you a good product. I worked at this plant where we cooked dirt. It glowed orange-red and flow

Repair a BTU VIP70 or buy a new HELLER??

I''m sure I remember BTU telling me that the VIP series got the same contollers as the ancient TRS14's. Someone may want to verify this - but if correct you can pick up a TRS for beer money & rob the controller. A new 7 zone BTU Pyramax can be ha
