we use the screen glue AMICON D125 F5 from Emerson company of Belgium and stencil is Varidot stencil from Loctite with thickness of 250 micrometers The squeegee is also from loctite, previously we use squeegee of material PU, it is easy to be broke

Some AOI manufacturers require you to put in a GOLD PCB. Gold PCB is a perfectly manufactured board - Correct placements, correct polarity, no solder short, a "GOOD" PCB. With the vision limitations of some AOI equipment components that have variatio

Genny, Xray systems ( or at least what I have seen ) are a manual based system. That is, you put the board on the machine and look at certain locations that you want to inspect. What we have in mind is an automated system that will catch obvious, no

What time? An in-line bot with a vision system tuned for paste recognition can measure a different portion of each board and keep pace with the placement machine all day long. I don't understand what you guys propose as an alternative. Realistical

Sure, researchers measure shear as an element of their material characterization process, but that does not make it an acceptance test. [Truly, this conversation is not uncommon on SMTnet. So, it would not surprise me if an enterprising something o

ZAM_BRI- I don't know how effective this may be but some points to include in the buy-off procedure: Before submitting the PO for the stencil you may also want to do a CAD to Stencil comparison to verify correct apertures.There are SW packages and co
