Fine-Line Circuits Limited specialize in the production of Space Grade RF Microwave PCBs. It builds PCBs using a variety of Low Loss/High-Performance laminates especially from Rogers, Nelco, Taconic and including Rogers RT Duroid Series (5000 & 6000) and similar materials. Further, these are with a special surface finish of 2-4 microns Electroplated Bondable Direct Gold on Copper (no nickel barrier). Fine-Line Circuits Limited is the only approved PCB Supplier for India’s foremost Space Agency - ISRO (Indian Space Research Organization) for their RT Duroid PCBs which go into their Satellite Communication Systems. Their capability to build RF Microwave PCBs with a special surface finish - Electrolytic Bondable Gold Direct on Copper and the gold thickness is of 2 to 4 microns and without Nickel ensuring the lowest signal losses and highest signal performance as the skin depth is optimised and as Nickel is absent, there are no signal losses and further it also gives excellent gold wire bondability. These PCBs go into all High-End Applications where Signal performance and reliability are key (like Onboard Satellite Communication Systems). They also specialize in building PCBs up to 24 layers with all other surface finish including ENIG, ENEPIG, Tin and Silver finishes on all base materials.
