Hi aram, Hot air is best. IR takes longer and is affected by the color of the part. Best post solder process that affects solder the most is handling.

150 grams)on a very thik board (> 3,5 mm)( we did it by DRS-24). On top to this, in case of need you can use also hot N2 (Nitrogen)and get low ppm of O2, for instance when soldering on OSP finisching using NC paste, etc, if required. Regards...GS

Our company wants to buy a rework station for BGA's. I would like to know what is a good BGA rework station. IR or hot air? Do we need a rework station with optical placement or can BGa's be placed manually during rework. We have seen a demo of an ER

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

I must say that I feel when the board has been correclty designed with corner marks on the edge of the BGA the optical systems are not necessary on 0.50/0.060" pitch. I like both air and IR the IR has the major benifit that you do not need all the ex

You can using Ersa IR550A Rework System. The unit was NOT using any hot air process. IR550A Rework System is worldwide the only system with a genuine closed loop control system. Which employs the current temperature at the component in order to regul

A little late but if this subject is still of interest the following paper from APE may be of interestwhen considering IR to Air Bath: HOT AIR versus IR and other convection Rework Systems HOT AIR is the most popularly chosen method of rework in th

Have you ever used the IR system, or do you think that hot air is better?
