Abstract

The invention discloses a technology applied to the printed circuit board of an electric power supply. The technology comprises the following steps that: S1: carrying out cutting; S2: obtaining an internal-layer graph; S3: carrying out internal-layer etching; S4: carrying out internal-layer AOI (Automated Optical Inspection); S5: carrying out lamination; S6: drilling a hole; S7: carrying out copper deposition; S8: carrying out full-plate electroplating; S9: manufacturing an external-layer circuit; S10: carrying out external-layer AOI; S11: carrying out screen printing and solder resisting; S12: carrying out surface treatment; and S13: forming. In the S5, a traditional rivet riveting process is omitted. In the S6, a magnetic workbench is adopted to lower hole drilling deviation, and therefore, the quality and the rate of finished products of the circuit board of the electric power supply are improved.

Description

technical field

[0001] The invention belongs to the field of printed circuit board manufacturing technology, and in particular relates to a technology of electric power printed circuit board. Background technique

[0002] The power supply circuit board is an important supporting component of electronic components, and it is also one of the important components of the electronics industry. It is used in almost every kind of electronic equipment, ranging from electronic watches and calculators to computers and communication electronic equipment. , Military weapon systems, etc.

[0003] With the development of electronic technology, the thickness of copper clad laminates is getting thinner and thinner, and power supply circuit boards are also developing from single-layer boards to multi-layer boards. At present, they mainly include 6-layer boards, 8-layer boards, 10-layer boards, 14-layer boards, etc. .

[0004] The existing production process of power supply circuit board ma...
