As PCB manufacturer china knows that, a backplane is an electronic system which contains slots and sockets to interconnect various PCB assemblies or devices in parallel to each other. It acts like a ‘Backbone’ for an electronic system and distributes low-voltage power to each slot.

Backplane testing evaluates the working of backplanes and passive electronic components such as resistors, capacitors, and diodes. The backplane provides the physical and electrical connections between system components, it is essential that it is operating within its prescribed parameters. In order to ensure the smooth working of a backplane, some tests are performed. The process of identifying the major faults in the backplane by using test processes is called backplane testing.
