The circuit board is the central brainpower behind most computerized devices. Without its guiding power, a device wouldn’t start up. During the manufacturing process and in the years of use afterward, producers must ensure protection for circuit boards from start to finish. Explore the best methods for protecting a printed circuit board.
Closely Monitor Manufacturing Processes
Printed circuit boards are invaluable but highly vulnerable. They need protection from the very beginning with closely monitored manufacturing processes. For example, you must perform lamination in a controlled environment with temperature and moisture levels in check. You can also use reaction injection molding techniques to create housings around PCBs and other items. Thermoplastic overmolding is a great way to safely protect the connections on the circuit board without subjecting it to extreme heat and pressure like other plastic injection methods would do.
Apply Post-Processing Sealants

Without this extra layer of polymeric film overlaying the board, it’ll be subject to corrosion in various environments. Be sure to apply the proper coating during post-processing sealing to maximize protection for long-term use. A well-applied conformal coating will protect against fluid damage, moisture buildup, corrosive contaminants, and ultraviolet radiation.
Install Effective Enclosures
PCB encasements have a certifiable level of protection, most commonly rated as IP65 or IP67. These ratings describe an enclosure’s effectiveness against the ingress of liquids and solids. An effective printed circuit board encasement will screw directly over the board, giving it room to breathe while eliminating the risk of damaging contaminants.
Understanding the best methods for protecting a printed circuit board helps manufacturers ensure their boards will remain functional and clean regardless of application. Though it’s impossible to protect against every eventuality, with these protective efforts in place at each stage of the PCB process, you can trust the integrity of your work for years to come.
