Technical Field

[0002] Flexible circuit board, also known as FPC, is a printed circuit board made of polyimide or polyester film as the substrate with high reliability and excellent flexibility. It has the characteristics of high wiring density, light weight, thin thickness and good bending properties. It is widely used in many products such as mobile phones, laptops, digital cameras, LCM, etc.

[0003] In the production process of flexible circuit boards, gluing is an indispensable step. Previously, there was a device that used a glue roller for gluing.

After the glue roller contacts the glue, it rotates upward to contact the circuit board. During this process, the glue will flow downward under the action of gravity, affecting the amount of glue that finally contacts the circuit board, which affects the gluing effect and needs to be improved.
