Ahhhh. If it only screwed up "consistantly" it would be alot easier!! yeah, bad board or overheat in the card rack (filters), kinked wire? good luck, my guess is it'll get more consistant as days pass

Run the lead free BGA side first. Then run the tin lead side second. We do this on some boards so that we don't overheat the components on the second side. There is no reason that the lead free solder needs to reflow on the second pass.

I have a HVC 102 reflow oven that will randomly shut down for over/under heat. On the 601 overheat protection zone 4 will read over 500c. Has anyone had this problem?

I'm currently researching new rework equipment, and was wondering if anyone had any recommendations. We currently have an older PACE hot air system that has had mixed results. It tends to overheat the board and IC. Is the IR any better, or has hot ai

Hi , As far as I experienced with wave reflow. If u have a refective thermal reader , u will see that the board is exposed to much more temp than the 120 deg that u set. Actually , once u see the board warp or comp. crack u should know that

Good day all, we have an evaporator for our PCB washer that has been fine up until recently. Everytime we run it, it boils over and makes a HUGE mess of everything. Any suggestions as to why this could be happening? Is it possible the temp controller

Phil is correct in his description of proper rework technique. Possible explanations of the reason for popping of your BGA are: * Thermal cycling of components cause them to flex on a different point in the cycle that the board possibly resulting in

Maybe I misinterpreted, because different people have different names for different devices, (i.e... I believe that the device that you refer to as your "surveyor", I refer to as a "profiler"), but did you already determine that your oven thermocoupl
