Consider how the vast majority of PCBs with BGAs are produced. Forced air convection. Anything that comes closer to duplication of the original soldering profile is what you desire. Did they build it with IR or Convection? The process engineer wa

The board thickness is 50 thousandths. The style of the BGA is a 324 ball BGA that has an isolated center region. The machine that I am using is the Air-Vac DRS25. I'm not too sure why the pads are being removed when I am desoldering. I know when

Hey Brian, Did you use the auto profile feature on your DRS25 machine to arrive at your profile? Our DRS25 has been doing quite well at larger BGA components. Most critical is a good preheat until the PCB reaches at least 140c, followed by a 2degC

'Hege is checking in for the DRS25 by Air Vac. Forced Air Convection reflow, and huge heating capacity for bottom side, ensuring minimum Delta T across the PCB during the process. Have 3 of these machines constantly in use for the last 2 and a half

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

Hello, I need some suggestion. I want to acquire a rework station that can handle small CSPs and has a vision system, but cost is a concern. Does anyone have an opinion on the brand I should look at? I see that there are some air-vac drs22 pre-owned

Air Vac DRS25. Hands down the best rework EQ. (my humble opinion, based on my own experience with rework EQ going back 15 years +) Right in your budget. Complete capability for rework. SMD, BGA, POP. Full profiling capability. Massive bottom heati

In order to be able to do full prototype assembly, you will need to be able to mount and reflow a large number of different devices of differing technology. One part might be a simple QFP, another might be a .4mm pitch uBGA. If you are prototyping a

HI, I work for a company in New England and recently had a unusually large number of boards fail after replacing a BGA on them. We use a AirVac DRS25 to remove and replace the BGA witch uses local forced hot air. We usually have at least a 90% s

Hi all, I'm in the market for a BGA rework machine capable of handling a wide range of PCB's, anything from little 2"X2" board up to 15"X15" back-plane boards that are 0.100" thick. I would like to find a machine that can remove BGA's & QFN's, clean
