Hole plugging device of base material and application thereof

Abstract

The invention discloses a hole plugging device of a base material and application thereof and belongs to the technical field of hole plugging devices of the base material. The hole plugging device is characterized by comprising a supporting platform for placing the base material with holes to be plugged, a material complementing mechanism of materials for plugging holes and a remaining material recovery mechanism. A vertical moving unit is arranged above the supporting platform, the vertical moving unit is connected with a horizontal driving device, a hole plugging head is arranged at a free end of the vertical moving unit, and the hole plugging head has a sharp edge and acts on the material surface directly to achieve hole plugging in the horizontal direction. The hole plugging device is compact in structure, good in hole plugging effect and intermittent and is used for plugging holes of the materials with the holes and pits smaller than 10 mums in the width.

Description

technical field [0001] The present invention relates to a plugging device, more specifically, to a plugging device for a substrate of a micron-sized small-pore-diameter substrate and its application. Background technique [0002] Plugging is a process of injecting specific materials into the interior of the substrate by vacuum, rolling or scraping. Applications include printed circuit boards (PCBs) and their surface mounts (SMTs), solar electrodes, etc. With its easy-to-implement and low-cost features, the plugging process has become one of the most common process methods for hole and pit filling. [0003] In the field of PCB, with the advancement of science and technology, electronic equipment is changing to high-speed, light, thin and short, which makes PCB develop along the road of high-density interconnection technology. Fine wiring and micro-aperture will become the mainstream in the future. The aperture scale of PCB board is urgently needed. Realize the transition fro...

AI Technical Summary

Problems solved by technology

[0006] 1. It is difficult to align the mesh and the pits. The alignment accuracy of tens of microns in the ordinary image alignment system has reached the limit, so the positional deviation between the mesh and the pits can cause only part of the hole to be plugged or no hole to be plugged at all;

[0007] 2. It is very difficult to open a mesh of tens to tens of microns on the surface of the wire mesh or steel mesh;

[0008] 3. The network cable of the screen may completely or partially cover the pit, which will affect the effect of the plug hole

[0010] The plugging effect of the two plugging methods is not ideal, and the material coated on the substrate cannot be recycled, so the pollution outside the plugging area is serious, and cleaning is required, which is time-consuming and costly
