Welding tool and welding method for flexible printing circuit board

Abstract

The invention relates to the technical field of communication and discloses a welding tool and a welding method for a flexible printing circuit board. The tool comprises a supporting seat, a rotatingshaft seat and a positioning seat. The rotating shaft seat is mounted on the supporting seat, the top of the rotating shaft seat is rotatably connected to the positioning seat, a positioning hole is formed in the first side of the rotating shaft seat on the supporting seat and is used for mounting an optical device, the top surface of the positioning seat is used for fixedly assembling a PCB connected to a first soft plate, the first soft plate is used for welding a first welding position located on the top surface of the optical device, the top of a side surface of a first side of the rotating shaft seat is a first bevel, and a matched detachable connecting structure is arranged between the first bevel and a bottom surface of the positioning seat. The welding tool and the welding method for the flexible printing circuit board provided by the invention can position relative positions of the first soft plate and the optical device quickly, are accurate to weld and position and high in reliability, and improve the stability an d accuracy of a welding process, so that the soft plate and the optical device are welded accurately.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a flexible printed circuit board welding tool and a welding method. Background technique [0002] Optical fiber communication mainly converts electrical information signals into laser communication signals, in which the optical transmitting module (TOSA device) converts electrical signals into optical signals, the optical receiving module (ROSA device) converts optical signals into electrical signals, and transmits information through optical fibers in the middle . At the same time, there is also a BOSA optical device (single-fiber bidirectional transceiver module) that can receive and transmit optical signals through a single optical fiber. On 6.25G, 10G and other optical communication modules, the optical communication device and the optical module PCB are connected through a soft board (flexible printed circuit board FPC), which can reduce the influence of inductance o...
