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

A couple of things you can look into 1. The proper bottom pre-heat of board. If you are applying only direct hot air to BGA without preheating can cause BGA's to warp and collapse un-even. 2. Moisture on you BGA's. If BGA's were not properly packa

That would be our first guess, also. Get the stuff analyzed to be sure. Another clue is if the white stuff disappears when you hit it with hot air from a rework station. The hot air is activate the flux. Good troubleshooting tool, but you're subj

If you are use to this kind of work, you can repair/replace these components with a simple hot air blower, (�100) Get a good air and temperature controlled hot air blower, and a skilled operator, mount a thermocoupler on a testboard, and learn the t
