BGA rework systems | 22 November, 2002

I am in the process of sourcing and ordering a BGA rework station. I only have exprerience with the OK-Industries (Now Metcal) BGA-3500 BGA rework system.

Any experience/input on other comparable systems would be much appreciated (Pace TF3000, Air-Vac DRS22c, Metcal APR5000 etc.).

In my experience the BGA-3500 seriously lacks in the pre-heater section when reworking larger, multilayer PCAs. I was using an early version of this system and have heard that the preheater was upgraded on latter units. Is this correct? If so, when (what year) was the change implimented?

Cheers

Maxtim, the rework stations you mentioned are the lower end low cost units, all great machines. Now days you can get a real deal in the used market on the top of the line models offered in rework stations. There are three rework station that I consider having great models and again some can be found on the used market for under 20K. These are the models and links to the manufactures; Conceptronics Freedom 2000 or 3000 great preheat, Air-Vac and SRT.

I have a preference on the freedom

Good luck

And what about the one from Ersa the IR550A?? It's more that 20k but did someone tried it?

I have conducted 2 BGA rework studies over the last 3 years or so. Each time I came to Air-Vac as the prefered machine.

I looked at all the models mentioned in the other posts here plus a few more. As a final step in the study I took the actual operators to view the final 3 and they all unanimously chose Air-Vac.

I know I haven't mentioned the specific details here but I'm sure you can make that comparison yourself and agree with my recommendation.

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 new underheater...but those blasted little microstencils..a refined technique. Pace offeres a nice system. Airvac $ is a big concern. and martin...by far my favorite some IR heat as a preheat and Convection for soldering...This my friend deserves a serious look. http://www.manncorp.com/rework-rework.htm

Best regards, Cal

Ersa is the choice for lower end repair and rework systems. Airvac is the choice for higher end systems. Stay away from low end hot air units. They typically do not present an even flow of heat across the component. The Ersa requires no nozzles, which is a great cost savings.

Any experience with the Conceptronic freedom-2000/HGR2000 system? I have the opportunity to pick one up for about 15k USD. The system new is approximately 51K, putting it into the high end of BGA/CSP/chip-scale rework systems, the specs. are really high end with very high accuracy and system controls . Is 15K for a used unit with very low hours a resonable price?

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. Conceptronics has a large preheat area using IR and also localize hot air. The machine is so robust that I purchased my own unit on my start up rework company.

Good luck

Good luck

And by the way $15k for the Freedom 2000 is a good deal, just make sure it has nozzles.
