I'm trying to develop a process for a small assembly consisting of two mirror image PBGA connectors, I've built the first prototype, but I ran into different problems: 1. The SMT connector was shifting during placemnt, and I knew one issue i have to

Very smooth. First, describe how this thing wowls at the moon. Next, state that process time is so long that you can't afford to make it. Finally, you ask someone to make it for you. Let's get Mikie to do it. Hey, Mikie ...

Hi, If your PCB is large, you waste a time. Any picture, you takes, will be with corner distortion. I suggest you to: 1. use AOI (manually or automatically) 2. try simulation of your PCB production before real SMT production process 3. use human FAI

I just got a report from MacDermid on Solder Mask Interface Attack Issue (SMIA) with Sterling Silver Process. Corrosive chemicals in the ImAg process get trapped under the soldermask edge and eat at the copper trace. They are experimenting with diffe

Thanks for your replies! So what I understand is that ICT in reality is "only" a production process safety net, but it's a net that in most practical cases is needed. What ICT can not catch is (all) bad solder joints. What are the methods to find t

Phil, In the considerations you make for choosing an AOI tool, you should check what a vendor delivers today and what will it be able to deliver in the future. As the role of AOI in the SMT production line evolves from "detection" to "prevention"

I will review some of the advantages/disadvantages of AOI vs. X-Ray one by one according to the main differences that you may find between them. * AOI uses optics that can "see" only visible elements. X-Ray can "see" hidden elements. There is a ve

Hi, Somebody can tell me an good site of images of the reflow process. I need this to put in a document for formation. This images are: Chip defects (like tombstone, missing, solder bridge, etc..) Cic defects Best regards

Dave: Your question is very astute. First let me make the observation that x-ray imaging is a technology that not many people in electronic fabrication are familiar with (but some think they are); consequently they are gullable acceptors of sales dis

Hi, We have a Juki KE-730, and was looking to buy a Zevatech KE-730 has a backup and for spares. We thought these machines would be identical, however when we looked at the circuit cards we noticed the image processing cards were quite different. I
