See also Fig. 1, detection operation in the ultrasonic cleaning chamber mainly is to be undertaken by fixing microscope 12, this printed circuit board (PCB) 10 is placed on the table in the testing process, the testing staff is by microscope 12 these printed circuit board (PCB)s 10 of observation, and directly move this printed circuit board (PCB) 10 at any time with manual type, so that observation comprehensively, operation very easily causes damage to solder joint and test point on this printed circuit board (PCB) 10 like this, if misoperation can have a strong impact on the circuit quality of connection of this printed circuit board (PCB) 10 and the reliability of subsequent job.
Therefore, in high-level efficiency epoch now, how to improve and detect the operation inconvenience that directly causes in the operation by manual contact, mobile printing circuit board, and because of the manual direct damage that this printed circuit board (PCB) to be detected causes of moving, reduce shortcomings such as successive process quality, become the industry problem demanding prompt solution.
The utility model content
For overcoming the shortcoming of above-mentioned prior art, fundamental purpose of the present utility model is to provide a kind of detection jig, and this detection jig is used for the detection operation of circuit board, makes circuit board convenient moving when detecting.
Another purpose of the present utility model is to provide a kind of detection jig, avoids the damage that causes because of this circuit board of manually-operated in the circuit board detecting operation.
Another purpose of the present utility model is to provide a kind of detection jig, promotes the operation quality of circuit board detecting.
Reach other purpose for achieving the above object, detection jig of the present utility model is used for the circuit board detecting operation, and this detection jig comprises: bearing part, bearer circuit plate; And sliding part, be located at this bearing part bottom, the circuit board on the bearing part is moved horizontally, artificial directly touching circuit board when avoiding detecting by this sliding part.
This sliding part is roller or rail structure, makes this bearing part produce displacement by this roller or convenient the moving of slide rail.This detection jig also comprises fixture, and circuit board is positioned on this bearing part.
Therefore, detection jig of the present utility model, can be in the detection operation after circuit board cleans, circuit board connect put and pre-fix on the bearing part of this detection jig, make things convenient for the user to move this detection jig, and should detect jig, be convenient to the user and carry out the testing circuit plate by this sliding part free shift that detects jig, avoid in the circuit board detecting operation damage that causes because of artificial this circuit board of direct control, promote circuit board detecting operation quality and subsequent conditioning circuit plate and electrically connect quality.
