I think forgot one most important thing. SMT is not all. In China, after the SMT process, QC, QA, casting, packing etc. It need lots of labors. I really one worker can handle 4 lines. Nokia still have two bid factory in China, Motorola has two also.

What type of feeder storage carts do you use for your feeders? I have many of the Fuji CP-6 racks, but I have found the few Mossman Tebbs racks mor useful and safer for the feeders. I am constantly fixing damaged tape leaf covers from operators not

It will be rigid, but not as rigid as something weighing 600lb's. We can't afford to cast/machine parts for a low cost machine. But we think have found techniques that can calibrate out any small distortions in the unit. Your comment about a decen

There's a place for both methods, but the advancements made year on year in 3D printing technology and quality give it the edge I reckon. We use 3D printing a lot and do it 'in house'. There's very little waste compared to machining a part from a bl

Suan: I'll take the "easy half" of your question I suspect you�re talking about Kleenox. It is a powder that you can sprinkle on your dross bed. Several points are: � Kleenox does not reduce dross. It reduces the amount of solder entrapped in dr

Hi Dave, What feeder model do you have? I took a quick look in my parts list manual and again, depending on your feeder model, you might be able to buy the needed part(s) from Zevatech/Juki. Have you checked with them yet? For example, the main feed

To best visualize the factors effecting resolution, carry in your minds eye an image of a light shadow being cast on the wall using a flashlight. The size of the flashlight filament would be the analagous x-ray "focal spot" The smoothness and/or roug
