Here's what I know about SMEMA and SMPI: SMEMA: An organization within IPC focusing on defining physical and computer protocol interface between production machines. Most equipment suppliers design their machines to physically meet SMEMA requireme

Basically its spec. gives surety regarding its chemical and physical properties. if he doesnt follow the spec then may be he may find good physical soldering appearance but chemically it may goes down through Electrical or Environmental testing and i

Hello! I think the point here to have a reliable counting system. No matter if it is given 5000 out of 5000 or 6000 out of 5000. What Jesus means is that there is a problem because the qty that the label says after the reel is counted doesn't match

David Thanks for telling me about this web-site! Great site! I very much appreciated this message. To be honest, after reading some of the other messages here on this forum, I almost decided that this site was not for me. Seems like most / all o

Hi You are right. I guess some of us missed this point in the way this on line dialog works. I like to put the specification that the PCB supplier must adhere to, on the Physical Print. The Physical print is often used by outgoing and incoming insp

C.Long, Have you thought of using a barcode reader system? Though costly, such a sytem would minimize the room for error and neglect by your operators. Yes, physical tickets would still need to be applied (barcodes labels) but there would be less ef

This sounds alot like the warping that we all see periodically in BGA. CTE of material is temperature dependent and not temperature changing rate dependent, so you are pretty much hosed by the physics. Regardless, I do like trying like crazy to g

no S**t, I was going into SMTnet to post a question, on : 1) what is the actual "physics" behind "Leaching" defect? what is the accurate desciption to define this defect? how to eliminate the general causes to this defect? If encounter, what work pr

Years ago, there was discussion of making a "IPC-A-640" to define requirements for assemblies comprised of more than a circuit board assembly. We don't know what happened after that. As an alternative consider: Telcordia GR-78 - Generic Requiremen
