Why do electronic devices and PCB need a protective layer?
The size, performance, and portability of electronic devices have undergone a revolution. These devices, ranging from smartphones and tablets to industrial technology like automation controls, are ubiquitous. They can be found in many challenging environments. However, without proper protection, contaminants can cause corrosion to the components inside the devices.
This can lead to degraded electronic performance, electrical shorts, and device failure. Additionally, the increasing complexity and density of printed circuit boards with high-performance components, LEDs, and miniaturized parts are creating a greater need for electronic protection coatings.

How is a protective conformal coating considered qualified for electronics grade?
Depending on the end product the PCB or electronics device is equipped on, there are many international certifications to qualify for an electronics-grade conformal coating.
Prostech electronics grade conformal coating with excellent performance can meet these requirements. To name some:
Flame Retardant: UL94V-0 certified
Salt spray performance tested in accordance with IEC60068-2-52 Severity 5
Mixed gas corrosion performance tested in accordance with IEC60068-2-60 Method 4
Tested in accordance with IPC-CC-830B / MIL-I-46058C
AS/EN 9100 and ISO 9001 certified coating centers
Nadcap® accreditation
RoHS, REACH compliant
FDA Device and Drug Master Files
It is not necessary to meet all of the above certifications to qualify your PCBs. For example, only medical electronics devices which directly expose to human skin, need to meet the strict FDA and ISO 19003-5 certification.
