Embodiment Construction

[0026] In order to facilitate the understanding of the present invention, the present invention will be described more fully below with reference to the associated drawings. Preferred embodiments of the invention are shown in the accompanying drawings. However, the present invention can be embodied in many different forms and is not limited to the embodiments described herein. On the contrary, these embodiments are provided to make the understanding of the disclosure of the present invention more thorough and comprehensive.

[0027] Such as figure 1 Shown, a kind of resin plug hole circuit board drilling method comprises the following steps:

[0028] S110, fixing the circuit board with the resin plug hole on the backing plate of the console. Fixing the circuit board on the backing plate instead of directly on the console, on the one hand, is beneficial to improve the load and buffer of the circuit board, and avoid the deflection and deformation of the circuit board. On the...

Abstract

The invention discloses a drilling method of resin plugging circuit boards. The drilling method comprises the following steps: fixing a circuit board on a backing board; sticking an aluminum covering board on the surface of the circuit board; pressing the covering board with a flexible pressure foot, and tightly pressing and fixing the covering board, the circuit board and the backing board on an operation desk; drilling a resin plugging hole with a first tool, wherein the diameter of the first tool is R1; coaxially stretching a second tool into a hole drilled by the first tool and rotating to remove plug dust, burrs and other foreign matters in the hole, wherein the diameter of the second tool is R2, and R2 is 0.02-0.1mm less than R1; after drilling, using the second tool slightly smaller than the first tool to drill in the hole again, removing resin residues and burrs in the hole by the rotation of the second tool, and adsorbing and discharging the dust in the hole by the negative pressure cyclone formed in gaps of hole walls when the second tool rotates in the hole at a high speed, so that the residues in the hole are removed effectively, the scrap rate of post-procedures is reduced, and the operation is simple.

Description

technical field [0001] The invention relates to the technical field of circuit board processing, in particular to a method for drilling resin plugged circuit boards. Background technique [0002] PCB (Printed Circuit Board), the Chinese name is printed circuit board, also known as printed circuit board, printed circuit board, is an important electronic component, a support for electronic components, and a provider of electrical connections for electronic components. [0003] With the development of miniaturization of assembly components, the wiring area and pattern design area of ​​PCB are also continuously reduced. In order to adapt to this development trend, PCB designers and manufacturers are constantly updating design concepts and manufacturing methods. The process of resin plugging is also a technical method invented by people to reduce the design size of PCB and cooperate with assembly components. Its bold design concept and scalable production have indeed played a g...
