Does anyone have suggestions or observations on what my maximum board temperature should be when doing BGA repairs on an SRT? In other words, How hot is too hot? Somebody set the bottom heater on our new BGA repair machine to blow at 275 C, and our

The boards I am referring to are definitely thick and large. But, on thinner smaller boards, is it OK to bring the board up to those higher temps because it takes less time? Many of the boards I am dealing with (large and small) are reaching 150-15

"Too Hot" is any more heat than what is needed to reflow the solder. You should have the Auto-Profile software for the machine, this will accurately monitor and record temps. There is also port for the component itself to monitor package temp. There

Our CP643E machine fails to recognise narrow view on its parts camera and confirmed that the VME48108 Picture processing board is the reason. The part number is AEEPN1603. Can anybody have the idea how much will it cost of i purchase a new one? How a

Hello, just a quick update on this issue. I disabled head 2 on beam 2 which was the second head I worked on, and left only active the head that I had work with first and ran dry cycle with. after disabling the head 2, the machine zeroed with no pr

Jeff & Ted, we have used a dispensing system too and yes, I agree, we are not too happy with the results. Not at the point that it doesn't work, though. I think our problem basicly is that we have selected an entry-level dipensing system. We are app

You are looking for a complete SMT assembly line plus possible X-Ray inspection and rework equipment. The 3 components of the SMT line are stencil printer, pick-n-place machine and reflow oven. How small are your components? 0603? 0402? What is the

I am looking at buying a pick and place machine to assemble the circuit boards we make. Most of the boards are small (2 to 10 square inches), most are 2 sided, and have maybe 20-50 parts per side. I use mostly 0805/0603 chips, SOT-23, SOD-123, SOIC
