Flexible PCB
Like rigid PCBs, flexible PCBs come in single, double or multilayer formats. As they need to be printed on a flexible material, they tend to cost more for fabrication. AS&R Circuits India Pvt. Ltd. makes Flexible PCBs with Immersion Silver, Immersion gold and OSP.
Manufacturing capabilities include:
- Adhesive less construction for thinner and more flexible circuits.
- Additive processing for higher density circuits. Trace and space capabilities down to .0015″ in production.
- Micro via sizes down to .001″ diameter for high density, 2-layer flex circuits.
- Selective plating of gold and tin lead enables multiple attachment methods on the same flexible circuit.
- Selective polyimide removal permits cantilevered and windowed leads.
- Alternate circuit layer materials such as beryllium copper, stainless steel and cupronickel can be used for optimum performance in unique applications.
- SMT and thru hole assembly services. Package sizes down to 0201 & .4mm pitch.
To do so, they are simply built using materials that might be waterproof, shockproof, corrosion-resistant or resistant to high-temperature oils – an option that traditional rigid PCBs may not have.
