Abstract

A maintenance fixture for PCB′A and an operating method thereof are disclosed to mitigate the problems that the PCB′A may be scrapped upon removing a conductive adhesive. The maintenance fixture includes a cover plate and a support baseplate which is configured to support a PCB′A and provided with a stopper unit; the cover plate is movably connected to the support baseplate at a first end to be rotatable towards and away from the support baseplate, and is provided with a barrier layer at a first side which is perpendicular to the rotation direction and close to the support baseplate; the barrier layer is configured to be contacted with the PCB′A upon the cover plate being rotated towards the support baseplate to cover an electronic component zone and expose an electrode zone of the PCB′A.

Claims16

Dependent claims

A maintenance fixture for printed circuit board assembly (PCB′A) comprising a support baseplate and a cover plate,

the support baseplate being configured to support a PCB′A to be maintained and being provided with a stopper unit, the stopper unit being configured to limit the PCB′A within a PCB′A stopping area defined by a surface of the support baseplate upon the support baseplate supporting the PCB′A;
the cover plate being movably connected to the support baseplate at a first end of the cover plate so as to be rotatable towards and away from the support baseplate with regard to the first end;
the cover plate being provided with a barrier layer at a first side of the cover plate, the first side being perpendicular to a rotation direction of the cover plate and close to the support baseplate;
the barrier layer being configured in such a manner that, upon the cover plate being rotated towards the support baseplate, the barrier layer being contacted with the PCB′A supported on the support baseplate to cover an electronic component zone of the PCB′A and also expose an electrode zone of the PCB′A at the same time;
wherein the stopper unit comprises a plurality of stopping posts disposed in the PCB′A stopping area, and the stopping posts can be inserted into stopping holes provided in the PCB′A respectively, upon the support baseplate supporting the PCB′A.
