A long time ago I used to have one of these machines that was very simple (no ramp control, etc... like the Air-Vac) and it was made by electrovert which is now speedline, I don't know if this is still in production however. You may want to try anyw

It sounds more as though you have a profiling problem primarily, however, if your placement is not square to the board, then you should get your machine setup correct first. After that you can get to the profiling. If the BGA is brought up to tempe

Hello All, My first visit here. I own and operate a small Industrial & Consumer Electronics Service Shop. There is more and more modules with high density fine pitch SMDs that we cannot handle. We bought PACE ThermoFlow BGA SMD station with a bunch o

Forced gas (hot air or N2 according to solder paste or flux) will be the solution. To rework Ceramic (Aluminum lid Heat Sink)BGA (32 mm square ) or Ceramic Colum Grid Array C-CGA 1,25 and 1,00 mm colum (pitch 42,5mm square), also them capped with a

'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

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

Omid, I have used the DRS24 for many years and have had similar problems with what you are talking about. I do not have any documents but I will tell you what I have seen. It sounds like an inconsistant collpse of the BGA. If one side of the BGA col

Thanks for the reply Hege, I calibrate the machines every 3 months and have checked that the board carrier to nozzle parralelism is ok. Have tried many different profile settings using a MOLE for readings but still collapsing on one corner. I did
