FAQ:

 

Q1:What is PCB Grid Testing or Bed of Nails Testing?

A1: Grid testing or Bed of Nails testing is a process used to check the performance of components mounted on a PCB board. This test uses a frame/fixture that contains various pins inserted into an epoxy phenolic glass cloth laminated sheet (G-10) in order to access all the PCB test points. These pins act as sensors which are aligned to make contact with the test points on the PCB board and are also connected with a measuring unit through wires. The position of the pins is designed and customized for each PCB based on the components or points on the board that need to be tested.

Limitations of PCB Grid Testing:

  • Fixtures used in bed of nails testing are expensive since they are mechanical and require a different wiring assembly for a different PCB board
  • Fixtures are mechanical so any change in the number of pins or their position require extra cost
  • This test doesn’t test continuity through connectors so there are the chances that the connectors’ faults may remain unnoticed.
  • Faults related to solder joints, excess solder, solder quality, and solder void also remain unidentified

This type of testing is called In-Circuit Testing. Another test process used for In-Circuit testing is Flying Probe Testing.
