Abstract

The invention discloses a hole plugging device and a hole plugging method for a circuit board. The hole plugging device comprises a carrying part (101), a temperature control part (102) and a hole plugging part (103); the carrying part (101)is used for carrying a circuit board (104), and the circuit board (104) is provided with a hole part (105) to be plugged; the temperature control part (102) is provided with a first heating piece (106) and a temperature sensor (107), wherein the first heating piece (106) is used for heating at least part of the hole part (105) to be plugged, and the temperature sensor (107) is used for detecting the temperature of the hole part (105) to be plugged; and the hole plugging part (103) is provided with a scraper (108), and the scraper (108) is driven back and forth relative to the circuit board (104) so as to plug the hole part (105) to be plugged. According to the hole plugging device, the hole plugging quality can be improved.

Description

technical field [0001] The invention relates to the technical field of circuit board manufacture, in particular to a circuit board plugging device and a plugging method. Background technique [0002] With the rapid development of electronic products in the direction of light, thin, short, small, high-density, multi-functional, and microelectronic integration technology, the requirements for the integration of electronic components that constitute these electronic products are also getting higher and higher. There are also higher requirements for the circuit of the board (PCB). [0003] The plug hole is an important process in the production of the circuit board. According to the requirements, the specified plug hole material needs to be filled into the via hole of the circuit board in a certain way. In addition to being filled to form a flat surface, the via hole can also be further fabricated with wiring in the via hole, thereby improving the wiring density of the product....
