Our capability includes single sided, double sided (with or without PTH), multi layer and flexi-rigid. All of our flexi circuits are constructed by building up component layers, eg. base, copper, coverlay, stiffener. Our flexible PCB’s are available at varying delivery times, depending on PCB type. Send your flexi-circuit PCB specifications to us by fax or e-mail for a quotation.
We are quality approved to ISO9001.
Flexible base materials are relatively dimensionally unstable and have to be processed on small step & repeated blanks, typically of a size only 20% of that used for rigid pcbs. Flexible PCBs are significantly more expensive than rigid PCBs.
We manufacture and supply flexi-rigid PCBs and flexible circuit boards. We construct flexible circuits by sequential build up of flexible component layers, such as base polyimide, copper, cover-lay, and stiffeners bonded by an adhesive layer (epoxy or acrylic).
Our capability includes single sided, double sided (with or without PTH), multi-layer and flexi-rigid PCBs.
The materials selected must be appropriate for either static (e.g. once only bend into a camera) or dynamic applications (e.g. hard disk drive). Stiffeners are normally applied in the region of the flexible circuit where components are mounted.
Mechanical tooling must be selected according to the volume and accuracy required. Tooling may be either CNC soft tooling (low cost but high unit costs), steel rule (volumes up to a few thousand pieces, medium cost, low dimensional stability), or hard steel punch & die sets (more durable, accurate, & higher cost).
Flexible and flex-rigid circuits are often used to achieve very tight packaging of electronics within small enclosures. Circuits may be assembled as “flat” systems which are folded to fit a smaller enclosure. They can serve as “printed” cable harnesses and of course when flexible electrical connections are required.
We will share our experience of 60 year’s making PCBs. Our aim is to supply high quality flexible circuits with reliable deliveries, competitive pricing, and excellent technical support. Flexible PCBs can be challenging to assemble, but our expertise makes any order a possibility. Our extensive in-house contract electronic assembly experience allows us to design production pallets for flexible PCBs which optimise assembly efficiency.
