Flexible PCB Manufacturer


Our capability includes single sided, double sided, multi-layer (1-10 layer) and flexi-rigid  (1-16 layer). 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 e-mail (sales@titanpcbs.com) for a quotation.

Flexible PCB & Flexi-Rigid PCB Quality Assurance


We are quality approved both by UL and ISO9002.

Flexible PCB Materials


Flexible circuits are constructed by building up component layers, eg. base, copper,  stiffener. Bonding between each component layer is provided by an adhesive layer. The materials selected must be appropriate for either static or dynamic applications .

If components are to be attached, the base material must be selected to withstand solder temperatures, and a stiffener may be added. 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. Final profiling and test for flexible PCBs will often be carried out as single circuits. Mechanical tooling must be selected according to the volume and accuracy required.
