Abstract

The invention discloses a small PCB cleaning jig which comprises a rectangular cleaning tank and a cover plate connected with the cleaning tank in a covering mode, the length and width of the cleaning tank are larger than those of a to-be-cleaned PCB by 5 mm, a cross-shaped bridge used for supporting the PCB is suspended in the cleaning tank, and after the PCB is placed in the cleaning tank, the cross-shaped bridge is used for supporting the PCB. The distance between the cross-shaped bridge and the bonding pads on the PCB is not less than 1mm, and the width of the cross-shaped bridge is more than 3mm less than the distance between the two adjacent bonding pads. The invention further provides a manufacturing method of the small PCB cleaning jig. The beneficial effects of the invention are that when the PCB is formed, foreign matters on the surface of the PCB can be cleaned; the CL <-> content in an ionic pollution test can be reduced, and the requirements of customers are met.

Description

【Technical field】 [0001] The invention relates to the technical field of PCB board cleaning, in particular to a small PCB board cleaning fixture and a manufacturing method thereof. 【Background technique】 [0002] With the development of PCB towards miniaturization and high quality, the size of PCB board is getting smaller and smaller, which makes it impossible to clean after molding. [Content of the invention] [0003] The invention discloses a small PCB board cleaning fixture and a manufacturing method thereof, which ensure that the surface of the PCB board can be cleaned without foreign matter, thereby solving the technical problems involved in the background art. [0004] For achieving the above object, the technical scheme of the present invention is: [0005] A small PCB board cleaning fixture includes a rectangular cleaning tank and a cover plate connected to the cleaning tank cover, the length and width of the cleaning tank are 5mm larger than the PCB board to be c...
