is it all right to reflow a BGA using a rework station but without applying a layer of solder paste on pcb. the diameter of the solder ball is 0.75 and the pitch is 1.5mm.

Maybe the issue is not a proper rework method. Your shorts on the corners are caused by too fast of a profile causing the corners of the BGA to get too hot, too fast, which made them curl, like tatter chips.

There are several out there. We will be doing some proprietary BGA installation in-house and I need a rework station. Has anyone had any experience with Focal Spot RD-500? Air-Vac DRS25? Or is there a better system out there for occasional to light u

What are the problems related to cleaning when using OA tacky flux to replace a PBGA. Will your standard inline cleaner be able to reach all the way under to clean all residue? BGA type is 1.27mm pitch .030 dia. ball plastic. Any info helpful! Thank

I never met such a issue.I use SRT1100&Freedom2000,and they works well with BGA larger than 3.5x3.5cm.

The shorts happen at corner of the BGA. The PCB thickness is 1.6mm, It is a PC motherboard with all thru hole connectors mounted on.The preheating is done using IR heater and the temp is 120-160 for about 70-80 sec.I am using ERSA IR550A

Hi Steven, Let me step back a bit. Have you ever removed and/or placed a QFP/BGA with a heatslug using IR before? Erhan
