It all depends where the voids are, and that's tough to do with a transmission x-ray. One needs to be able tilt the assembly at 45-degrees during x-ray, so you can get an idea where the void is. Or, you spend some big bucks for an x-ray laminography

Hi Christina, What would you be basing the yields off of? Is it solder defect, component placement, etc....? I have worked for a flex house for quite a few years. You are right. The Polyimide is very dimentionally unstable. (even more so on humid da

Q1: I thought we have a industry standard for this. A1: We're unaware of such a standard. IPC-7525 - Stencil Design Guidelines has a brief section on stencil inspection. We've talked about it previously on SMTnet. If you can't find it in the Archiv

I would definately try to sell the bosses on the Grid-lok over the gel piggies. We evaluated both and wound up buying the Gel (for close to the same money). On an MPM if you put enough gel packs in the vacuum box (to support the board) it holds the b

Hello We have been working on the MPM's for over 11 years now. And we have never had any trouble with that circuit, just goes to show you. If you have one of the old, old manuals you will find a lot of errors. They corrected them as they went. We
