2. Printed circuit board milling - Wikipedia

   en.wikipedia.org/wiki/Printed_circuit_board_milling

   A milled printed circuit board. Printed circuit board milling (also: isolation milling) is the milling process used for removing areas of copper from a sheet of printed circuit board (PCB) material to recreate the pads, signal traces and structures according to patterns from a digital circuit board plan known as a layout file.

3. Printed circuit board - Wikipedia

   en.wikipedia.org/wiki/Printed_circuit_board

   Through-hole (leaded) resistors Through-hole devices mounted on the circuit board of a mid-1980s Commodore 64 home computer A box of drill bits used for making holes in printed circuit boards. While tungsten-carbide bits are very hard, they eventually wear out or break. Drilling is a considerable part of the cost of a through-hole printed ...

[1] [2] CircuitMaker is available as freeware, and the hardware designed with it may be used for commercial and non-commercial purposes without limitations. [3]

5. Phenolic paper - Wikipedia

   en.wikipedia.org/wiki/Phenolic_paper

   The back of two circuit boards. The brown one is an FR-2 made of paper phenol. Phenolic paper is a material often used to make printed circuit board substrates (the flat board to which the components and traces are attached). It is a very tough board made of wood fibre and phenolic polymers. It is most commonly brown in colour, and is a fibre ...

6. Perfboard - Wikipedia

   en.wikipedia.org/wiki/Perfboard

   Software for PCB layout can often be used to generate perfboard layouts as well. In this case, the designer positions the components so all leads fall on intersections of a 0.1 inches (2.54 mm) grid. In this case, the designer positions the components so all leads fall on intersections of a 0.1 inches (2.54 mm) grid.

7. Via (electronics) - Wikipedia

   en.wikipedia.org/wiki/Via_(electronics)

   In printed circuit board (PCB) design, a via consists of two pads in corresponding positions on different copper layers of the board, that are electrically connected by a hole through the board. [ citation needed ] The hole is made conductive by electroplating , or is lined with a tube or a rivet .

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 ...
