I tested out the OK unit and found it to be a "down and dirty" rework machine that will do BGAs if demeanding thermal requirements are not needed. My largest concern was the lack of bottom side preheat. I have recently purchased the Air-Vac DRS24 a

Thanks for all of your suggestions. I ended up borrowing a Pace Worldwide PH100 Preheater, which worked like a charm. I'm in the process of purchasing one for our own shop. I had to place the aluminum pcb directly onto the PH100's ceramic heating pla

We're quoting out a new board design, and one of the prospective suppliers is pitching a silver coating process over hot air leveling. We haven't had experience with boards of this type, and I am concerned about any processing issues that may come u

I need to purchase a rework tool mainly for QFP's including 30mm x 30mm. I was looking at a Metcal QX2 and a Pace TF200. I would welcome any comments on these two products or any other suggestions. Also, is a preheater necessary?

I have evaluated SRT, Air-Vac and Conceptronic rework stations. All three machines offer great BGA and Micro BGA rework capability. But the one I have preferred is the Conceptronic Freedom 2000, as a matter of fact I have purchased two freedom 2000 i

If you think the problem is occurring in the box and it is wide spread, consider replacing your solder paste with your paste supplier. There are paste formulations aimed at the solder balling issue that some LF pastes create. On tuning your reflow r

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
