Our company is finishing up a design prototype for an easy to use re-balling fixture. 100% ball attach, and you can re-ball more than one BGA at a time. Initial investment will be in fixture cost, but you will be able to re-ball several chips in ar

You will need to prepare the component and site for rework. Using solder wick remove the solder from the pad site and the component balls. You can also use a heated Vacuum desoldering tool. To reball we have been using Winslow Automation reballing ki

Thanks Dave...it's such a good site for reworking BGA's (reballing). But what about when it comes to re-attaching the BGA onto the PCB? We are using Flextac Stencils but I found out that the apertures of their stencil is bigger than our pads for the

Frank, I am not talking about the masking on the PCB. I am actually talking about the masking on the solder side of the BGA. We have a very very high dollar BGA and are trying to reclaim alot for reuse. When we remove the BGA from the assembly, you

By the way you asked the question, we assume that by "reballing" you mean bumping, we should be able to figure that out: * Volume of the ball = ( pi*d^�)/6 = [355/113] *0.6*0.6*0.6]/6 = 0.11mm^3 * Volume of solder required = 2*volume of ball = 2*0.11

Hello, few comments: - what is the criteria to decide if re-ball or not a PBGA? - any electrical test is performed toPBGAs before reball ? - what in case the reballing has been done on a electrical damaged PBGA? In that case the replacement of

Hi, We are experimenting with BGA recovery and we would like to know When is BGA Reballing not recommended?
