Method for improving large layout efficiency of optical module PCB product

Abstract

The invention discloses a method for improving the large layout efficiency of an optical module PCB product, the PCB product is formed by connecting single chips through a V-CUT groove, the depth of the V-CUT groove is 0.2-0.4 mm, and the angle of the vertex angle of the cross section is 45 degrees; the automatic numerical control production process comprises a fixed-depth fishing and beveling program, an AVI program and an electric measurement jig program. According to the invention, V-CUT groove connection is realized between the single chips, the area of the PCB is increased, automatic or horizontal line cleaning is realized, and the production efficiency is improved; by arranging fixed-depth fishing and beveling program, the air suction, positioning, plate loading and unloading time issaved, and the production efficiency is improved by 50%; by arranging an electrical testing jig, the shutdown fault frequency and the number of defective products caused by abrasion of the milling cutter are reduced, and the production efficiency is improved; by setting the AVI program, defective products and rotating shaft damage caused by misalignment of the center line of the milling cutter and the center line of the rotating shaft can be monitored in real time, and then the production efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of PCB product preparation, in particular to a method for improving the efficiency of large typesetting of optical module PCB products. Background technique [0002] The optical module PCB product is to fix the circuit components on the board. PCB products are small in size and easy to install. They are suitable for intelligent electronic components such as TVs, computers, and notebooks. The size of existing optical module PCB products is small, and the imposition size is also small. Because the board is too small, it cannot automatically pass through the horizontal cleaning line, so it can only be taped to pass through the horizontal line, resulting in low cleaning efficiency. During the production and processing of existing PCB boards, the precision and wear of milling cutters affect production efficiency. The machining accuracy of the milling cutter determines the tooth profile accuracy of the gear. Th...

Problems solved by technology

The automatic production process is continuous production, and the output is large. Once there are factors that lead to product failure, but they are not found in time, it will lead to a batch of products that are not qualified and cause a lot of waste.

Some data show that in the automatic processing system, the downtime caused by milling cutter wear accounts for 20%-25% of the total number of failures, resulting in a reduction in production efficiency of more than 20%.
