Abstract

The invention discloses an intelligent manufacturing process of a printed circuit board. The manufacturing process comprises the following specific materials and steps: S1) PCB raw material double-sided cutting; S2) scrubbing and cleaning; S3) positioning hole drilling; S4) photoresist coating; S5) carrying out exposure, developing, etching and film removing; S6) inner layer coarsening and deoxidation, and carrying out full lamination through a lamination machine; S7) numerical control boring; S8) thin copper plating, coating inspection, pasting a photoconductive electroplating resistant dry film or coating a photoconductive electroplating resistant agent and surface layer bottom plate exposure; S9) developing and board repairing; S10) circuit board pattern plating; S11) tin-lead alloy electroplating or nickel / gold plating, film removing and etching; S12) screen printing of a solder resist pattern or a photo-induced solder resist pattern; S13) printing a character pattern; and S14) inspection of finished products and package and delivery. The manufacturing process is more precise; meanwhile, overall structure of the processed product is more uniform, and the product is not easy tocrack, thereby ensuring product reliability; meanwhile, the product has the advantage of uniform thickness and not easy to crack; and the production process is environmentally friendly, and is suitable for batch production line production.

Description

technical field [0001] The invention relates to the technical field of circuit board processing, in particular to an intelligent manufacturing process of printed circuit boards. Background technique [0002] Before the appearance of printed circuit boards, the interconnection between electronic components relied on the direct connection of wires to form a complete circuit. In contemporary times, circuit panels only exist as effective experimental tools, and printed circuit boards have become an absolute dominant position in the electronics industry. Printed circuit boards {PCB circuit boards}, also known as printed circuit boards, are electronic A provider of electrical connections to components. Its development has a history of more than 100 years; its design is mainly layout design; the main advantage of using circuit boards is that it greatly reduces wiring and assembly errors, and improves the automation level and production labor rate. [0003] With the rapid developm...
