I am concerned about delamination and other modes of damaging the board itself. Am I mistaken to believe that raising the entire board to near reflow temperatures (during the repair of a single BGA) may damage the quality of the board?

wats the thickness of your board.. and the dimension.. I would not heat the board beyond 150deg C.. coz if the board is thick and large.. it will take a long time to reach that temp..and you will burn off your flux.causing poor solder joint. Ind

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

"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

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

Does the pcba:s comes directly from the assembly line, You are going to do rework on? If faulty pcba:s comes back from, let say a customer from outside or the pcba:s has been on Your shelf for some days/weeks, exposed to open environment (humidity in

My company is hooking up a delta max wave solder machine but we can seem to get the estop error to go away any one have a any experience with this issue.

That is solderpaste dependent. Please check your solderpaste datasheet for print speed range.

What error is it throwing?
