A circuit board drilling aid

Abstract

The invention discloses a circuit board drilling aid and belongs to the technical field of circuit board drilling. The circuit board drilling aid can fill a drilling-assisting long hole on a drillingmachine with a long auxiliary drilling block such that the vacant area of a circuit board directly above the drilling-assisting long hole is reduced. Thus, during a drilling process, the area on the circuit board that is recessed downward from the drilling center can be effectively reduced, thereby reducing the workload of a worker for later leveling, reducing the area requiring leveling, loweringthe leveling difficult, and thus improving the overall efficiency of circuit board production. In addition, the use of an adaptive deformation hollow capsule and a sealing layer achieves the preliminary fixation of the inner layer of the aid and the secondary fixation of the upper side. The double fixation effectively reduces the displacement of the aid due to the vibration during drilling, reduces the probability of micro deformation of the circuit board, and improves the drilling quality.

Description

technical field [0001] The invention relates to the technical field of circuit board drilling, and more specifically, relates to a circuit board drilling assistant. Background technique [0002] Printed circuit board, also known as printed circuit board, is a provider of electrical connections for electronic components. It has been developed for more than 100 years; the main advantage of people using circuit boards is to greatly reduce wiring and assembly errors Automation level and production labor rate. With the rapid development of electronic information technology, printed circuit boards (referred to as PCB) are developing in the direction of high density, high integration, high speed and high frequency. The mutual conduction between PCB layers can be realized by back drilling technology. Back drilling technology refers to first drilling through holes in the PCB graphics area, and then electroplating the copper layer on the PCB after the first level drilling holes, so t...

Problems solved by technology

[0003] Existing worktables used on circuit board drilling machines generally have a long hole, which is used for the drill bit to pass through the circuit board without hindrance, so that the drilling process is smoother without pause, and the hole wall is smooth without Obvious burrs increase the quality of the drilling, but due to the existence of the long hole, the bottom of the part of the circuit board directly above the long hole is vacant. The center of the upper drilled hole is sunken downward, resulting in local unevenness of the circuit board after drilling, which affects the quality of the finished circuit board, increases the workload of the staff for later leveling, and reduces the overall efficiency of the circuit board manufacturing
