Conformal coating using selective spraying technology

We operate a sophisticated and automated process to selectively coat PCB assemblies. Utilising our leading edge PVA coating system, we can selectively coat PCB assemblies with a wide variety of conformal coating products.PCB assembly with conformal coating applied by Gemini Tec

 Robotic spraying allows fine amounts of coating to be selectively dispensed onto PCB's with high accuracy. Multi axis control allows the coating to sprayed on, around and underneath complex components. The distinct advantage of this technique means there is no longer a need to mask the keep out areas of the PCB. Selectively spraying allows a price point typically 20% to 30% lower than traditional coating methods. 

We clean our products to exceed the guidelines of IPC CH-65 A and J-STD 001-D, also known as MIL SPEC. We use Zero Ion contamination testing to ensure the level of cleanliness prior to coating.
