Please email this checklist to the rep setting up your PCB files.File Submission: (Files Submitted during or directly after order placement):[ ] I am sending 1 zip file containing only the required files for fastest processing.[ ] I understand order will be manufactured when file is received; no changes can be made.Gerber Layer File Preparation:[ ] I have previewed my design using Gerber Viewer[ ] My design requirements fall within the standard guidelines -- see capabilities[ ] Files are Gerber RS274X (embedded apertures) or RS274D or ODB++ (includes separate aperture list).[ ] All spaces/traces are a minimum of .003 (3 mil) or larger.[ ] All outer layers (top and/or bottom) are positive and do not require manual merging.[ ] All holes have proper pads for through-hole connections from top to bottom layer.[ ] Power and ground layers have sufficient clearances for all holes, including mounting holes to prevent shorting.[ ] My board is viewed as looking through from top (component) layer side.Single Sided - 1 layer Boards: YOU MUST PREVIEW 1- LAYER FILES![ ] My board is viewed as looking through from top (component) layer side.[ ] Right reading copper text is located somewhere on the single side (+ silkscreen if applicable).[ ] I understand all boards are through-hole plated; We will add copper pads to bare side of 1-sided PCBs.4-6 layer Quick Turn Files:[ ] Inner layers are individual layers (either positive or negative) that do not require manual merging.[ ] Internal ground plane layers have recommended clearance sizes for all holes, including mounting holes.[ ] Ground and power layers are clearly marked to indicate proper polarity.
Board Shape Outline located on at least 1 Gerber layer[ ] Board outline is drawn around perimeter only using a non-breaking trace
Drill Setup/Hole Sizes; ASCII text file showing X&Y coordinates for holes[ ] I have verified NC drill file is NOT a Gerber layer or drawing.[ ] I have reviewed the recommended pads & clearances for preset drill sizes.[ ] I have a separate tool size list or the tool sizes are listed within the header of my excellon drill file.
Solder Mask[ ] I have included both top and bottom solder mask files or indicated on the order form to use common mask for both sides. I have indicated on order form if entire side should be flooded with mask in lieu of a mask layer.[ ] Solder mask swell should be at least .006 larger than copper surfaces to keep mask off pads.Silkscreen;[ ] I included a top silkscreen file and optional bottom silkscreen file (needed if added to order).[ ] Silkscreen does not cover soldering surfaces. No clip performed on this service.[ ] Silkscreen traces are drawn with .007 (7mil) or larger aperture line width (not height) to ensure legibility. [ ] It should be remembered that if your project has tight spacing and requires solder mask dams, a Green solder mask should be used. A different color of the letter screen can be used if there is a need to have a visual check for RoHs compliant or Prototype. Green solder mask is also the most cost-effective choice of mask. Gloss or semi Gloss would also be more cost-effective than a Matte finish.
