Conformal Coating & PCB Potting

Conformal Coating and PCB Potting are essential processes for enhancing the durability and longevity of electronic assemblies.

Conformal Coating is able to protect circuits from moisture, dust, chemicals, and fungal contamination, preventing short circuits and corrosion. This is ideal for applications where the PCB may be exposed to harsh atmospheres but requires some level of repairability.

PCB Potting involves encapsulating the entire assembly in a solid or gel-like resin compound. This provides superior protection against heavy physical impact, strong vibration, moisture immersion, and extreme temperatures. It also offers excellent electrical insulation and makes the assembly tamper-resistant.

These services are critical across industries where reliability is non-negotiable. By choosing the right protection method, we ensure your products perform reliably in the most challenging conditions.
