PCBA (printed circuit board assembly) ultrasonic cleaning clamp, device and method

Abstract

The invention discloses a PCBA (printed circuit board assembly) ultrasonic cleaning clamp, device and method. The PCBA ultrasonic cleaning clamp comprises a frame-shaped first clamping part, wherein the periphery of the first clamping part is provided with a plurality of support rods, a frame-shaped second clamping part is connected onto the support rods, in addition, the first clamping part and the second clamping part are in vertical correspondence, the periphery of the second clamping part is fixedly provided with a plurality of positioning sleeves, the positioning sleeves are connected with the support rods in a sleeving way, the first clamping part comprises a first square frame and a plurality of groove-shaped first clamp strips arranged on the first square frame at intervals, the second clamp part comprises a second square frame and a plurality of groove-shaped second clamping strips arranged above the second square frame at intervals, and in addition, the second clamp strips are in one-to-one correspondence to the openings of the first clamp strips. The PCBA ultrasonic cleaning clamp provided by the invention has the advantages that a plurality of PCBA boards can be simultaneously clamped, and the problem that the number of the PCBA boards capable of being placed onto the clamp in the prior art is small can be solved; meanwhile, the dimension shape of the clamp is adjustable, the PCBA boards in different shapes and dimensions can be placed, and diversified requirements of products can be met.

Description

technical field [0001] The invention relates to the technical field of circuit board cleaning, in particular to a PCBA ultrasonic cleaning fixture, device and method. Background technique [0002] PCBA is the abbreviation of Printed Circuit Board+Assembly, which means that the empty PCB board passes through the SMT upper part, and then goes through the whole process of DIP plug-in, that is, various electronic devices are assembled on the empty PCB board through the surface packaging process. Flux, tin beads and tin slag will remain on the assembled PCB board. Ultrasonic cleaning is generally used to clean PCBA boards in the industry, but there will still be white powder between the IC pins after cleaning, which has become a technical problem in the industry; , with the diversification of products, more specific cleaning fixtures are required in the traditional cleaning technology, and the use of traditional cleaning fixtures also makes PCBA cleaning time longer, and the numb...

Problems solved by technology

Flux, tin beads and tin slag will remain on the assembled PCB board. Ultrasonic cleaning is generally used to clean PCBA boards in the industry, but there will still be white powder between the IC pins after cleaning, which has become a technical problem in the industry; , with the diversification of products, more specific cleaning fixtures are required in the traditional cleaning technology, and the use of traditional cleaning fixtures also makes PCBA cleaning time longer, and the number of PCBA boards that can be placed on the fixtures for cleaning is small, which leads to traditional Cleaning Fixtures Affects Productivity
