Flexible PCB

Flex PCB consist of a thin insulating polymer film having conductive circuit patterns affixed thereto and typically supplied with a thin polymer coating to protect the conductor circuits

Flexible PCB

Flexible printed circuit boards, also called Flexible PCB or Flex PCB, derive their name for their ability to enable the circuitry to be designed to fit the electronic device or product, as opposed to building the device to conform to the circuit board. Flex boards are characterized by a distinctly patterned printed circuitry and component arrangement highlighted by a malleable base material.

We have the PCB manufacturing capabilities to build simple to complex bare boards. Please review the example printed circuits below and let us know if you have any questions or would like a formal quote


Rigid PCB is a type of regular PCB which can not be twisted or folded into any shape because it comes with FR4 stiffener which is very useful for added amount of stiffness and rigidity.


Rigid-Flex printed circuit boards are boards using a combination of flexible and rigid board technologies in an application. Most rigid flex boards consist of multiple layers of flexible circuit substrates attached to one or more rigid boards externally and/or internally, depending upon the design of the application.


Among all metal core PCBs (aka MCPCBs, known for their ability to provide effective thermal dissipation for electronic products), Aluminum PCBs is the most common type – the base material consists of aluminum core with standard FR4.


HDI PCB is widely used to reduce the weight and overall dimensions of products, as well as to enhance the electrical performance of the device. 


A high-frequency PCB can meet your needs when incorporating a special signal requirement into your electronic components and products.
