Risk Factors for PCB Boards (Part 1)
It is every designers target to ensure their PCB boards are robust and can function effectively and smoothly. However, there are two factors that can lead to damaged PCBs. These are environmental factors, and problems that can develop during the design and production stages of flexible PCB manufacture. In this article, we outline several environmental factors that damage PCB boards.
Dust is present in most environments, and can cause two issues for PCBs. The first concern is that the dust may insulate the board, reducing the ability for heat from the board to dissipate. Dust can damage devices such as computers and televisions. The second way is that some dust can be a medium for static charge.
Liquid chemicals such as cleaning solutions may give off fumes. If the PCB is operating in close proximity to the fumes, they can build up on the unit and slowly corrode the linkages.
Manufacturing Errors Can Damage PCBs
Every PCB design is different as it is designed to meet different needs. While engineers will follow regular guidelines in designing their boards, and test the boards at various stages to ensure functionality, there is a risk of human error. In addition to the risk of human error, there are inevitable risks in manufacturing. The manufacture of boards is complex, and there are several opportunities for defects to be included in the manufacturing process.
