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.
1. plug hole mode 1: ink plug hole
Ink plug hole is also called through hole plug oil, as the name implies, is through pcb ink plug hole screen printing machine, the use of screen printing, the ink through the screen and scraper, through the printing method, through the hole drilled in the pcb board, will be filled with ink; This is to prevent the hole from being oxidized in contact with air for a long time, which will affect the electrical performance and even lead to waste board; the concentration of ink plug hole, the use of pcb circuit board plug hole screen printing machine performance technology will have a greater impact on the quality.
II. Plug Hole Method 2: Aluminum Plug Hole
The aluminum plug hole actually refers to the plug hole on the hole of the aluminum sheet with the help of the aluminum sheet during the plug hole process, which is different from the ink plug hole described above. The ink plug hole mainly refers to the plug hole process using ink. The purpose of aluminum plug hole is mainly to avoid the phenomenon of oil plug caused by direct plug hole, waste ink, and pollute pcb board surface, affecting beauty and quality performance, it is a process method to assist in improving the quality of plug holes. Xin Jinhui has developed a series of professional pcb plug hole equipment, such as vacuum plug hole machine and pcb line circuit board ink resin plug hole machine, which have been widely recognized and selected by top 100 enterprises in pcb industry.
3. plug hole method 3: resin plug hole
One reason for resin plug hole and ink plug hole is that resin is replaced with ink, but the pcb plug hole equipment adopted has higher requirements, because the density of resin is higher, and hidden plug requires greater pressure and precision when filling holes. For example, the PCB intelligent full-automatic pressure plug hole machine developed by Xin Jinhui has key technologies such as pressurization and locking, realizing full plug hole with one knife, high quality and high efficiency; secondly, the resin plug hole is mainly used for situations where the ink plug hole cannot be satisfied or the ink plug hole is easy to cause the plug hole to be defective, such as the through hole plug hole on the multi-layer board BGA, the buried hole of the inner HDI, the through hole with larger board thickness, etc. Secondly, if the requirements for the resin plug hole are high, a more high-end vacuum resin plug hole machine may be required.
