Printed circuit board (PCB) production typically involves applying a coating to protect the component from aspects that could otherwise hinder its performance and shorten its life span. Understanding the most appropriate one to choose starts with knowing the types of PCB coatings. However, there are also other factors to consider that will influence the outcome. Here’s what you need to know.
People apply coatings to PCBs and get numerous advantages. The right ones can safeguard delicate parts from corrosion and other environmental dangers. Plus, since many of these coatings have insulating properties, designers can make their boards with the conductors closer together without noticing performance degradation. Many PCB specialists use thin and flexible substrates to achieve the progressively greater miniaturization required for many of today’s devices. That’s important, but PCB coating options can support smaller designs, too.
