These commonly used PCB circuit board plug hole methods
Before introducing which kinds of pcb plug hole methods are available and which pcb plug hole machine is applicable to each plug hole method, we must first understand what pcb plug hole is all about. The pcb plug hole is to allow electrical and signal transmission to different layers of pcb. First, a hole is drilled to form a channel by inserting materials, thus realizing transmission; in this issue, the editor will take you to understand the ways to form through holes, that is, to introduce the ways and equipment of plug holes.

PCB proofing etching process considerations
PCB proofing circuit board generally need to go through the etching operation. For example, the whole plate copper plating process needs to etch away the parts other than the photosensitive film, but the uniformity of the lines must be maintained during the etching operation. At the same time, copper must be plated twice on all parts of the plate surface, and the periphery of the panel needs to be etched away at the same time, so as to maintain the uniformity and reliability of the lines and the panel.

General PCB board substrate materials can be divided into two categories: rigid substrate materials and flexible substrate materials. The most common rigid substrate materials are copper clad laminates. Specific materials are the following four: resin, glass fiber cloth, FR-4, and aluminum substrate.

Substrate (Substrate): The substrate is the main body of the PCB and is usually made of an insulating material, such as glass fiber reinforced epoxy resin (FR-4). It provides mechanical strength and support structure while having good insulation properties.

In short, PCB is an important basis for the connection and support between electronic components. It is widely used in electronic products in various fields such as computers, mobile phones, televisions, automotive electronics, medical equipment, etc., and is an indispensable part of the development of modern electronic technology.
