Technical field
The present invention relates to a kind of improvement of PCB capillary test fixture, in particular to one kind can test circuit board either with or without
Rosin joint, solder skip or short circuit phenomenon, in order to avoid the PCB capillary test fixture of the damage of product.
Background technique
PCB (Printed Circuit Board), Chinese is printed circuit board, also known as printed wiring board, is important
Electronic component, be the supporter of electronic component, be electronic component electrical connection carrier.Since it is using electronic seal
The production of brush art, therefore referred to as " print " circuit board.
Existing test fixture is usually only capable of for the electronic equipments such as mobile phone being fixed in single specific plane, such as horizontal plane
Or vertical plane, to carry out subsequent production and processing, assembling or test.However, when electronic equipment is placed into different positions
Test when, need to rotate electronic equipment when tilting to different states and being tested, then can generate biggish position error,
Usage experience of the geomagnetic sensor indoors in position fixing process can so be reduced.Therefore, existing test fixture will be difficult to
It meets the requirements.
