0.05mm 0.25mm Rigid Flexible Circuit Board Fabrics Textiles Test Equipment
Fabrics, Textiles, Test Equipment For Rigid-Flexible And Flexible Printed Circuits (FPC)
One stop OEM service:
If required, we can source, organise and manage all aspects of PCB design to ensure your product meets all required standards and is fully optimised for easy and cost-effective manufacture.
A well designed PCB means:
- A reduction in production problems
- Improved quality control
- Reduced costs
- Reduced manufacturing times
We work to provide our customers with small and large quantities of competitively priced printed circuit boards.
