- Valuable Final ArtworkA term used in "Streamlined PCB Design“.Artwork for electronic circuits which have been laid out and documented in forms, perfectly suited to the photo-imaging and numeric-controlled tooling processes of printed circuit manufacture. It is termed "final" because it has been thoroughly checked for errors and any corrected as needed and is now ready for manufacture without further work by the PCB designer . It is valuable because it could be exchanged with a customer for money or other support.
- ViaA plated through hole (PTH) in a Printed Circuit Board that is used to provide electrical connection between a trace on one layer of the Printed Circuit Board to a trace on another layer. Since it is not used to mount component leads, it is generally a small hole and pad diameter.
- VoidThe absence of any substances in a localized area. (e.g. missing plating in a hole, or missing track).
- V-ScoringRather than completing a route path around the board edge, the edges are "scored" to allow breaking boards apart after assembly. This is another way to palletize / panelized the boards. This method creates two beveled scoring lines along the perimeter of your boards. This makes it easier to break apart the boards at a later date. You would receive your boards in panel form like tab routing.
PCB Design Tips
When designing a PCB, try to limit
the amount of draws you use.
Draws use a lot of memory and slows the programming time. Ex.: Use a flash for pads instead of draws. If for some reason we need to increase or decrease that pad size, it can easily be done by changing the D-code but if they are done with draws it could be a nightmare.
