  2. PCB congener list - Wikipedia

    en.wikipedia.org/wiki/PCB_congener_list

    Congener descriptors give a shorthand notation for geometry and substituent positions. The twelve congeners that display all four of the descriptors are referred to as being "dioxin-like", referring both to their toxicity and structural features which make them similar to 2,3,7,8-tetrachlorodibenzo-p-dioxin (2378-TCDD).

  3. Power electronic substrate - Wikipedia

    en.wikipedia.org/wiki/Power_electronic_substrate

    Classical printed circuit board (PCB) material can be used (this method is typically used with through-hole technology components). This is also true for low-power applications (from some milliwatts to some watts), as the PCB can be thermally enhanced by using thermal vias or wide tracks to improve convection. An advantage of this method is ...

  4. PCB NC formats - Wikipedia

    en.wikipedia.org/wiki/PCB_NC_formats

    PCB NC drill files convey PCB drilling and routing information. The NC formats were originally designed by CNC drill and route machine vendors as proprietary input formats for their equipment, and are known under their company name: Excellon, Hitachi, Sieb & Meyer, Posalux, etc.

  7. TopoR - Wikipedia

    en.wikipedia.org/wiki/TopoR

    TopoR can be used as an external autorouter for third-party layout editors or in conjunction with Eremex's own schematic capture and layout editor Delta Design (DD). TopoR imports input in Delta Design's FST format, as Specctra-/ELECTRA-compatible DSN design files, [19] or in P-CAD PCB ASCII (2000, 2002, 2004), PADS PCB ASCII (3.5, 4.0, 5.0, 2005.0), or EAGLE BRD XML formats (6.x).

  8. Coupon (PWB) - Wikipedia

    en.wikipedia.org/wiki/Coupon_(PWB)

    A coupon or test coupon is a printed circuit board (PCB) used to test the quality of a printed wiring board (PWB) fabrication process. Test coupons are fabricated on the same panel as the PWBs, typically at the edges. Coupons are then inspected to ensure proper layer alignment, electrical connectivity, and cross sectioned to inspect internal ...

  9. List price - Wikipedia

    en.wikipedia.org/wiki/List_price

    This 1916 advertisement distinguishes the list price and a lower our special price.. The list price, also known as the manufacturer's suggested retail price (MSRP), or the recommended retail price (RRP), or the suggested retail price (SRP) of a product is the price at which its manufacturer notionally recommends that a retailer sell the product.
