A flexible board with high reliability and an assembly system thereof

Abstract

The invention relates to a flexible board with high reliability and an assembling system thereof, comprises a flexible board body, a main via region, a standard pad region and a pair of positioning holes, wherein the main via region and the standard pad region are respectively arranged at two ends of the flexible board body, a pair of positioning holes are close to the standard pad region, and thepair of positioning holes are symmetrical along the vertical centerline of the flexible board body; A main via hole correspond to that electrical network of the pins of the photoelectric device or module to be fabricated or tested is arranged in the main via hole area. In the standard pad area there is a set of standard pads that correspond to the electrical network of the main vias and conform to industry standards. The invention has the advantages of effectively avoiding the abnormality caused by the complete symmetry of the external dimension and the deflection of the pins to one side of the component soldering and assembling, and avoiding the poor butt joint or even misalignment of the pads of the flexible board and the test circuit board although the pads are dense.

Description

technical field [0001] The invention relates to the technical field of photoelectric communication equipment, in particular to a high-reliability flexible board and an assembly system thereof. Background technique [0002] In modern communications, low power consumption, high density, and integration have become the development trend of optoelectronic devices and even communication modules. In the case of limited space and volume, flexible boards can be bent and folded freely, and can be freely arranged and arranged according to layout requirements. Stretchable and has good heat dissipation characteristics, the use of flexible boards in communication modules can effectively achieve dense assembly and connection of modules. However, for components whose external dimensions are completely symmetrical but the pins are biased to one side (that is, the pins are not centrally symmetrical), after manual welding or assembly, after rotating the components 180 degrees relative to the ...

Problems solved by technology

However, if the component is shifted towards the position where the preset pad is located by a certain distance, although the component pins can be aligned with the preset pad, the position of the entire component on the circuit board has deviated from the correct soldering position, which may As a result, the surrounding pads preset for other components are blocked or covered, which affects the welding of other components, and many components are polarized. Once the welding is abnormal, the loss will be huge.
