Problems solved by technology

[0002] In the current rigid-flex board structure, there are many FPC base ends connected to gold fingers. In this structure, some FPCs have good flexibility, but the gold fingers at the FPC base end are too soft, which is not conducive to repeated insertion and removal; The gold finger is rigid and easy to plug in and out, but the connected FPC is not flexible enough, so the gold finger at the base of the FPC cannot be easily plugged in and out multiple times, which affects the plugging effect

Embodiment Construction

[0008] exist figure 1 Among them, including PCB substrates 1 and 5, FPC single-sided substrates 2 and 6, gold fingers 3 and 7 on the side of the FPC substrate, and FR45 and 8 in the middle of the double-layer FPC, gold fingers 3 and 7 on the side of the FPC substrate are the FPC substrate The insulator on the end side is formed after opening a window. When assembling and using this product, it is necessary to connect the PCB (1 and 5) and other devices through the FPC substrate (2 and 6) and gold fingers (3 and 7), because there is FR4 between gold fingers 3 and 7 Liner, so it has strong rigidity and can withstand multiple insertions and withdrawals. When gold fingers 3 and 7 are inserted and pulled out, because the connection between gold fingers (2 and 6) is FPC, and the middle is hollow, there is a good Flexible, can withstand multiple flexing. In this way, the whole structure not only ensures the multiple insertion and extraction of gold fingers, but also ensures the ele...

Abstract

The invention discloses a four-layer rigid- flexible pcb structure, wherein, a double-layer FPC base end connects with a double-face golden finger, but another base end of the double-layer FPC connects with PCB (rigid pcb) mutually, and the double-layer FPC middle forms hollow, the structure makes the golden finger on the FPC base end having certain thickness, keeping strong rigidity, the FPC middle part for connecting the rigid pcb has better flexible, the whole structure can ensure insert and pull out the golden finger on the FPC base end oftenly, electrical connection of the whole product, and keep flexible performance of the FPC middle part.

Description

technical field [0001] The invention designs a structure of a four-layer soft-rigid combination board. Background technique [0002] In the current rigid-flex board structure, there are many FPC base ends connected to gold fingers. In this structure, some FPCs have good flexibility, but the gold fingers at the FPC base end are too soft, which is not conducive to repeated insertion and removal; The gold finger is rigid and easy to plug in and out, but the connected FPC is not flexible enough, so that the gold finger at the base of the FPC cannot be easily plugged in and out multiple times, which affects the plugging effect. Contents of the invention [0003] The present invention is to solve the above problems. A four-layer soft-rigid combination board structure is designed, which can not only ensure the rigidity of the gold finger at the base end of the FPC, facilitate insertion and removal, but also ensure the flexibility of the connected FPC, which is convenient for the ...
