The early process of Rigid-flex PCB board is use connector or hotbar process to connect two PCBs with flex board.This combination with the flex board and rigid PCB process  is time-consuming and laborious, so customers transfer the assembly to PCB manufacturer to make rigid-flex PCB. In addition to the price, the use of Rigid-flex Board has many advantages, listed as follows: It can effectively save the space on the circuit board and save the use of the connector or the HotBar process Because of flex PCB and rigid PCB get together, so that require the use of connectors or HotBar process space  can be saved, saved space is
