I have been applying solder spheres to BGA packages. During the process, the spheres are run over a stencil for placement. The spheres tend to stick to each other (and clump), even away from the stencil pattern, when it is humid in the work area. I'm

Thanks, George. Yep, we got through all of that. Then went to cleaning the nozzle changers, etc. Had a tech in the other day from the broker that we bought the machine from, and discovered that the problem in changer 4 is that we don't have any

Hola Grayboard, I've had the same situation with these components, I changed the stencil apertures a little bit and use a stepped stencil (5-6mil), after some trials we were able to get decent yields, but we still had some failures, what we discover

We are working with SMT lines consisting of machines opalxii after 5/6 years of operation have appeared problems in operation of the engines on the x and y axes. I disassembled the engines from the machine and I removed the cap that covers the encod

The company I work for is installing a SMT prototype line, and I've been asked to determine the cost of operation. I know there will be cost for solder, solder paste, flux, stencils, glue, nitrogen, ect... I just want to make sure I'm not missing any

While I can't directly answer your question, we've had the same problem here occasionally. Our wash parameters are roughly the same as yours. It seems to be correlated to the diameter of the cap (larger caps will balloon while most smaller caps are

Hi all, I partially installed the F4G files in a Windows XP machine. Partially because this machine is not connected to any production machines. So I installed the library, programmer group and the cp6 optimizer. The Data Manager works. I can see al

The longer the oven, the better. You will have much more capabilities in creating the precise profiles the way you want them(with10-12 zone oven). I have worked with ovens from 2 to 12 zones and the difference is huge. In my opinion try to get a 10zo
