2 Layer Flexible PCB

Product introduction

Flexible PCBs with 2 layers are widely used in mobile phones, digital cameras, LCMs, PDAs, and notebook computers. They are popular due to their lightweight, thin thickness, and high wiring density. These circuit boards are made from high-quality materials such as polyester or polyimide film, which ensure high reliability and excellent flexibility. Two types of flexible circuit boards are available in the market: the flexible board with glue and the flexible board without glue. Due to its unique flexible function, this type of circuit board is being used increasingly across various industries.
The functionality of the 2 layer flexible PCBs also makes them suitable for use in several other products such as medical equipment, portable CD players, MP4 players, household VCD, DVD, and even in automotive and aerospace fields. As a leading Chinese manufacturer, our focus is on providing our clients with high-quality products and top-notch customer service. If you need to inquire about our products or services, please do not hesitate to contact us. We are always happy to help.

Specification

Features

The head shape function of this PCB is exceptional, as it provides the flexibility to bend, fold, and wind it easily, while being able to move around and unfold in a three-dimensional space without any hindrance.
This circuit board boasts remarkable heat dissipation capabilities, enabling it to deliver even faster and more efficient heat dissipation in a more compact form factor.
The integration of components and wire connections is easily achieved with this circuit board's unique design, leading to its advantages in achieving light weight, miniaturization, and thinning. This allows for a compact and slim circuit board that excels in functionality and efficiency.
The quality standards that these boards meet are very strict and they undergo vigorous testing for both their reliability and performance. However, despite their high quality, they are still very competitively priced.
