Hi Phil, Tabs every time for me, but running in volume so the slow down in tool travel for cutting important. Have used Cencorp 1000 & 1300BR, and Asys ADS01 - both in line systems with grippers from the top to hold the board and the router underne

| Can anyone in this world produce such small PCB/PWB trace widths? Lots of theory so far, but have not found anyone yet who can do it in practice. Hi Daniel! I attended this years IPC Printed Circuits Expo down in Long Beach, and witnessed a live

Electropolishing definitely improves the print characteristics of both Laser-cut and Chem-etch stencils. The caveat here is avoid over polishing which results in rounding of the edges and/or enlargement of the openings. Over polishing is typically th

Dan, The rationale to use laser cut stencils in my experience is based on the benefits to paste release. Laser cut stencils are "supposed" to have a smoother inner aperture wall. That, combined with the trapezoidal shape (which can be emulated with

CK, That is the exact machine I had. I bought a Dek 265LT in 1997 or late 96. Was one of the first Dek 265LTs made. Never had to use epoxy blackened fiducials and it worked great with 1/2 etched or laser cut fiducials. Chris

0.65mm pitch QFP. I believe that this is the borderline for Fine Pitch. Will I have a good paste release with Chem-etch matched with a rubber squeegee? I'm planning of a 15% reduction on the Width and no reduction on the length. Any feedback whether
