Flexible Pcb Assembly Process

Product Details

Application:

Mobile phone

Emphasis on the light weight and thin thickness of the flexible circuit board can effectively save the product volume, easily connect the battery, microphone, and the button into one.

Computer and LCD screen

Utilizes the integrated circuit configuration of the flexible circuit board, and the thin thickness. Turns the digital signal into a picture and presents it through the LCD screen.

CD Walkman

Focus on the three-dimensional space assembly characteristics and thin thickness of flexible circuit boards. Turn huge CD into a companion

Disk drive

Whether it's a hard disk or a floppy disk, it relies heavily on the high softness of the FPC and the ultra-thin thickness of 0.1mm for fast reading. Whether it's PC or NOTEBOOK.
