Hello, I am a new user of the machine CSM84VZ III and learn to program. After formatting a disc machine lost all settings(I did not know that the settings are on the disc), most of which I have already set. Now I have a problem such that when I try t

Hey Ya'll! Have any of you ever worked with one of V-Tek's "Economax" tape and reel machines? The biggest thing I'm curious about is the type of cover tape that these machines use. It's something they call P.S.A. (Pressure Sensitive Adhesive)cover t

everything Stephen said + it is really important that you have correct diameter pipes. If diameter is too small there will be a significant pressure drop in pipes (and machines have their consumption 100-500 NL - normal liters / min) and pipe system

We always reduce side to side, EXAMPLE: 12 mil width reduced to .010". Do you guys check viscosity ? Also maybe your guys are appling to much pressure on the sqweegee blades.

First, this is the result of bad printer setup. Adjust knife pressure, PCB gap, separation speed, tooling, and stencil cleaning. Pay attention to the coating of contacts pad and height of solder mask of PCB.

First, we agree with Loco that your QFP is nonwetting, rather than dewetting. Your sceen-shots look like ol' timey SnPb paste recipes. Turn-up the heaterometer dial. Second, on nitrogen: * We kinda think your O2 needs to be around 100ppm with 99.99%

Just a bullet! My results are, .005" stencil thickness should measure between .0055" - .006" if your pressure is correct, metal blades and snap-off is set up correctly. Do you have aperture reductions at the QFP locations "typicial industry standard

MA/NY DDave, I'll take your money. I'm betting on the Class II, whatever that is, because: * Solder is the same. * Board is the same from a fabrication and probably materials standpoint. * Components are the same. * Processing is the same. ... but
