2. 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 ...

4. Printed circuit board manufacturing - Wikipedia

   en.wikipedia.org/wiki/Printed_circuit_board...

   Printed circuit board manufacturing is the process of manufacturing bare printed circuit boards (PCBs) and populating them with electronic components. It involves the full assembly of a board into a functional circuit board. In board manufacturing, multiple PCBs are grouped on a single panel for efficient processing.

5. Routing (electronic design automation) - Wikipedia

   en.wikipedia.org/wiki/Routing_(electronic_design...

   In electronic design, wire routing, commonly called simply routing, is a step in the design of printed circuit boards (PCBs) and integrated circuits (ICs). It builds on a preceding step, called placement , which determines the location of each active element of an IC or component on a PCB.

6. Rework (electronics) - Wikipedia

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

   Reballing involves dismantling, heating the chip until it can be removed from the board, typically with a hot-air gun and vacuum pickup tool, removing the device, removing solder remaining on the device and board, putting new solder balls in place, replacing the original device if there was a poor connection, or using a new one, and heating the ...

7. In-circuit testing - Wikipedia

   en.wikipedia.org/wiki/In-circuit_testing

   A common form of in-circuit testing uses a bed-of-nails tester.This is a fixture that uses an array of spring-loaded pins known as "pogo pins". When a printed circuit board is aligned with and pressed down onto the bed-of-nails tester, the pins make electrical contact with locations on the circuit board, allowing them to be used as test points for in-circuit testing.

8. Failure of electronic components - Wikipedia

   en.wikipedia.org/wiki/Failure_of_electronic...

   A resistor removed from a high voltage tube circuit shows damage from voltaic arcing on the resistive metal oxide layer. Resistors can fail open or short, alongside their value changing under environmental conditions and outside performance limits. Examples of resistor failures include: Manufacturing defects causing intermittent problems.

9. Component placement - Wikipedia

   en.wikipedia.org/wiki/Component_placement

   Component placement is an electronics manufacturing process that places electrical components precisely on printed circuit boards (PCBs) to create electrical interconnections between functional components and the interconnecting circuitry in the PCBs (leads-pads). The component leads must be accurately immersed in the solder paste previously ...
