Does anyone know of a source for salvaging column grid arrays with damaged columns (through bad handling or removed from a PCBA)? Not reballing, but recoluming.

I am looking for some old scrape boards that have either CCGA or CBGA, high temp columns or balled devices for some process experiments I am doing. If anyone has some please let me know, the company name or supplier will not be see or used Many than

We need to rework for CCGA1657 (Ceramic Column Grid Array): removal and soldering. Its size: 42.5 x 42.5 mm. Its height is 7.25 - 9.61 mm. We use 63Tin-37Lead water-soluble paste. Our mini-stencil is 6-mil with 27 mil apertures. Please show your expe

As far as I have determined, the Gel and Tacky are the same animal. Just flux works well, I did forget to mention that this flux only method will not work with a CCGA (Ceramic Column Grid Array) since these columns are not meant to be reflowed.

Are there formalized standards for the properties of solder balls? No Get IPC-7095 �Design & Assembly Process Implementation for BGA's�. General comments about array package solder balls are: * Ceramic packages use harder solder, like 90/10. * Pla

Abraham, Lead free components in a leaded process should not be a problem. The problem increases with leaded components in a lead free process. For the most part, the only difference that you will see is in BGA procesing. If a BGA is lead free, the

I have an application that uses 0201 devices coupled with ceramic column grid arrays. The coplanarity of the balls is specified not to exceed 7 mils! 4 mil foil for 0201's with a selective buildup to 7mil for the ceramic. Bloody designers! Take y

MoonMan, I'll take a crack at the list. Feel free to answer the ones I don't! 1. Solderability is a parameter which indicates how well a component can be soldered. As far as Solder Termination Coatings go, here are some up�s and down�s of a few. Ha
