Description

Technical Field

[0001] The invention belongs to the technical field of PCB auxiliary processing, and in particular relates to a method for repairing a circuit board pit. Background Art

[0002] PCB (Printed Circuit Board), also known as printed circuit board in Chinese, is an important electronic component, a support for electronic components, and a carrier for electrical connection of electronic components. Because it is made by electronic printing, it is called a printed circuit board.

[0003] PCB circuit boards are mainly composed of pads, vias, mounting holes, wires, components, connectors, filling, electrical boundaries, etc. The main functions of each component are as follows:

[0004] Pad: A metal hole used to solder component pins;

[0005] Via: A metal hole used to connect the pins of components between layers;

[0006] Mounting holes: used to fix the printed circuit board;

[0007] Wire: Copper film used to connect the electrical network pins of components;

[0008] In the field of PCB processing and production, pits formed by PCB pads, hole rings, copper surface bruises and scratches often appear, which may cause serious product scrapping and losses. At present, copper paste can be used to repair pits formed by scratches and bruises on the copper surface of PCB. However, this repair method is usually prohibited in PCB manufacturers. In the prior art, manual repair rods are also used to repair the grooves on the board surface by squeezing the raised copper surface around the pit through the repair head. However, because it is a manual operation, the repair rod needs to be pressed and rolled to flatten the copper surface, which is laborious and inefficient. Summary of the invention

[0015] S4. After the repair is completed, turn off the switch, remove the repair head, and continue to the next cycle.

[0016] In the present invention, the repair head is driven by the vibration motors of the X-axis and the Y-axis to squeeze the copper sheet at the defective part, and the stepless speed regulating motor adjusts the vibration size to perform repair.

[0017] Furthermore, the repair head is any one of a conical repair head, a frustoconical repair head, a spherical repair head, and a knife-shaped repair head.

By switching different repair heads, the cone can repair pits on finished circuit board ICs and other small pads; the frustum can be used to repair pits on larger pads on finished or semi-finished circuit boards, or to level the board surface; the sphere can be used to repair pits on large copper sheets on finished or semi-finished circuit boards; the knife-shaped head can finely repair BGA and IC small pads.

[0019] Furthermore, a shock-absorbing sponge is provided in the vibration part, and the shock-absorbing sponge has the function of absorbing sound and reducing shock.

[0020] Furthermore, the Y-axis vibration motor is disposed in the vibration part.

[0027] Compared with manual repair, which requires pressing hard, the electric repair machine only needs to place the repair head on the defect, and the vibration motor drives the road repair head to squeeze the defect. The hand only needs to control the position and direction, and there is no need to press hard, so the repair accuracy is higher. BRIEF DESCRIPTION OF THE DRAWINGS
