What is electronic component failure in PCB?  

Electronic component failure is when a component is not functioning or performing as expected. It eventually damages the product. These defects may result in a complete breakdown or degradation in the performance of the device. 

It is crucial to perform root-cause analysis to find out the failure modes of components. This research requires some information that includes:

--Circuit board design data including dimensions, stresses, loads, etc.

--Parts, material, and process specifications.

--Manufacturing process reports involving chemical analyses, mechanical properties, inspections, and performance testing. 

--Information related to working environments.

--Maintenance record comprising vibration analysis and previous failures. 

All this data will assist in failure modes and effective analysis of a board.

PCBs comprise of numerous components including through-hole components and surface mount devices (SMD). Defects may arise due to several reasons during manufacturing, assembly, and shipping. There should be a focus on continuous improvement in the areas that are prone to failures.
