The term “PCB Backplane Circuit Board” generally refers to a larger format printed circuit board. They are the backbone that connects multiple PCBs together to ultimately form a computer bus. Typically, they do not contain active components; rather, they serve as a connection center between active duty PCBs. Backplane PCBs often incorporate a wide variety of features including blind / buried vias, high-speed / high-signal integrity materials, back drilling, and controlled impedance.
PCB Backplane Board Application
Generally used as a backbone within a system such as control panels for industrial, computing, military use. They provide greater reliability in connecting multiple PCBs due to their static nature, as opposed to cables that need to be flexed every time a card is removed, thereby reducing the life of that component/connection.
PCB Backplane Circuit Board Testing
Visual Inspection: In this test, components on the backplane are checked individually for correct placement. It also includes checking solder joints and component orientation.
Electrical Tests: This test checks the connections by sending an electrical current through the pins and traces on the board. It has two major areas to test:
- Continuity or open circuit which means there is a connection between the pins.
- Isolation or short which means there is a space between the pins to make sure that there is no connection.
The electrical test provides confirmation in two terms, i.e, ‘Continuity’ if a connection exists between the test points and ‘Short’ if doesn’t. This test is important because unwanted connections can cause interference on the board and cause malfunctions.
Functional Test: To check how the circuitry will work after integrating with the final device or application intended.
Signal Integrity Analysis and Simulation: Due to the higher speed signal formed in the base plate. To analyze such signals, network analyzers can play a role in both time and frequency domain measurements.
