"Guest" is right, actually. CSP's are essentially BGA's, but typically the pitch and ball diameters are much smaller and in some cases, the pads of the CSP's can not be screen printed. If that's the case, you'd have to have flux-dip capabilities on

Hi Pete and Dave, I already check with Practical component, Tessera and TopLine Dummy component they said they only have up to 0.5mm pitch CSP. Anyway, thanks for your input... Do both of you know in the market right now is there any 0.4mm pitch C

These days I've met much CSP fails.it's .5mm pitch,5x5mm outline CSP.we must reball it and mount it again on the boards because these Parts are very expensive and we can't scrape it off.is there anyone has any precieus experience or suggestions?or wh

It is CSP reliability issue, which is the mobile CPU from Spreadtrum. All the tests passed and shipped to customer. They assembly them and tested but failed. After they reflow this CSP with hot air gun, some of the boards passed. We got some board

Hi, all, does anyone know what mechanical test regime is used to qualify underfills for CSP use.

I work on CSP Rework Process Development. Can anyone suggest a way by which the component top temperature during removal / replacement can be reduced for the same solder joint temperatures (for example providing metal shields over component top in t

Reading some technical report I found the term "CSP", but no explanation. I guess something about Chip Scale Package... but not sure. Could someone please explain it to me? Rgds, Anderson

Steve: Excellent description of CSP's. I think the term "Micro BGA" has been trademarked by Amkor.

I think for x-ray, it really depend what package you are looking at. For CSP, it should be at least min 90KV, min 5 micro focus size. CSP definitely need a higher mag and resolution.
