Bare Board-Quick Board Introducing Guide


PCB stands for Printed Circuit Board; it is a board that connects various joints of the circuit along with and allow signals and power to be routed between different components. A bare board is also called as copper clad having no element on board. In early times circuits were designed using point to point wiring which made them time-to consume to manufacture, very difficult to debug and prone to failures.

1. What is Bare Board

Boards with no components there are bare-board tested for shorts and opens. A short is a connection between two points that should not be joined whereas an open is a missing connection between points that should be connected.

2.Bare board test

Bare board test is the tests done on unpopulated boards where netlist defined circuit connection is adequately verified on the fabricated board. A small voltage is applied and is checked at the appropriate points, a “short,” “open” are identified in these types of tests. Industrial CT scanning can show details of soldered path and connections by generating a 3D rendering of the board along with 2D image slices.

Ideally, when a bare board is tested, then it can be assured that it is a good board. However, that depends upon the assumption that the board has been designed efficiently. A circuit board that has an issue with the design can still pass the bare boards electrical test and not function correctly, This does not happen very often but is always a possibility.
