Abstract

The invention belongs to the technical field of electronic product processing and relates to a circuit board pre-tin-dipping pressing structure. According to the circuit board pre-tin-dipping pressingstructure of the invention, a compression area can be selected according to the size of an electronic product, so that adaptability can be improved; reliable pressing and tin dipping can be conveniently carried out on the pins of a pin element on the back surface of the electronic element of the circuit board; a pressing force can be adjusted according to the pressing requirement of the product,and therefore, the reliability of the use of the pressing structure can be improved. The circuit board pre-tin-dipping pressing structure comprises a workbench; supporting rods are longitudinally arranged at the four corners of the top end of the workbench; a fixing plate parallel to the workbench is transversely arranged at the top ends of the four supporting rods; a threaded pipe is rotatably arranged in the middle of the fixing plate in a longitudinal penetrating manner; an adjusting screw rod is arranged in the middle of the threaded pipe in a screwed mode; an adjusting disc is transversely arranged at the bottom end of the adjusting screw rod; adjusting through holes which pass through the adjusting disc in a vertical direction are longitudinally formed in the areas of the top end ofthe adjusting disc which are adjacent to the edge of the top end of the adjusting disc; pressing rods are longitudinally arranged in the adjusting through holes in a sliding mode; and a plurality of fixing through holes are formed in the circumference of the adjusting disc.

Description

technical field [0001] The invention relates to the technical field of electronic product processing, in particular to a circuit board pre-impregnated tin compaction structure. Background technique [0002] As we all know, circuit components are placed on the circuit board after being inserted into the pins, and then fixed by soldering, but the way of soldering has been eliminated, and it is replaced by immersion tin, which needs to be compressed and dissipated to facilitate further Good to make the electronic components firmly soldered. [0003] After retrieval, the patent of the present invention with the Chinese patent publication number CN110000725A discloses a circuit board pre-impregnated tin compaction structure, including a workbench, the upper end of the workbench is symmetrically fixedly connected with a connecting plate, and the two connecting plates are far away from the end of the workbench A mounting plate is fixedly connected together, a cylinder is installed...
