The shorts happen at corner of the BGA. The PCB thickness is 1.6mm, It is a PC motherboard with all thru hole connectors mounted on.The preheating is done using IR heater and the temp is 120-160 for about 70-80 sec.I am using ERSA IR550A

I have been looking into buying a rework station like ERSA or PDR. What I am questioning is how well will these systems reflow BGA's with metal top/cover that are reflective. In addition, when preheating the board would dark body packages absorb te

Maxtim- I have used APE's Sniper, airvac, Mecal's 3500, PDR, Pace, and MArtin's rework stations. APE Sniper does the Job but to much automation and not user friendly software. PDR is to much IR and no convection. Metcal's work good now with the ne

Maxtim, Again I have implemented BGA rework in four CM's and the machine that I have selected is the Conceptronics. In contract manufacturing you will have to be prepare to rework from the smallest to the largest boards with lots of ground planes. Co

My suggest is using Ersa IR55A or IR650A. http://www.ersa.de/en/ If you looking for your quality, you need this system. I had try it many time, is better then hot air. and you can set the profile as you like, even Flat Peak on the Lead Free Rework.

We evaluated several rework machines a few years ago and decided on the Finetech CRS-10. It outperformed the Airvac DRS25 machine. We didn't bring in the Focal Spot because it uses IR. The Focal Spot System does not have a solder removal option and

Can anyone tell me an approximate cost of the PDR 410 and/or ERSA IR rework station? Is the main advantage of using these systems over a hot air machine in that nozzles are not needed?

Might want to look at this: http://www.pdr-rework.com/pdfs/IR_XT5_Professional.pdf We recently purchased one here and I love it. Steve

Any concerns on the IR in melting connectors etc. simply cover the part with aluminum foil. That will prevent any heat from attacking the component. The Ersa unit is in my mind the best bang for the buck.
