Before introducing the types of PCB plugging methods and which PCB plugging machines are suitable for each plugging method, we must first understand what PCB plugging is; PCB plugging is to allow electrical and signal transmission to For different layers of PCB, first open an opening by drilling, and then plug in the material to form a channel to achieve transmission. In this issue, the editor will take you to understand the ways to form through holes, that is, to introduce the methods of plugging holes and equipment.
1. Plugging method 1: Ink plugging
Ink plugging is also called via plugging oil. As the name suggests, it uses a screen printing method to pass the ink through the screen and scraper, and through the holes drilled on the PCB board through the printing method. , will be filled with ink; this is done to prevent the holes from oxidizing in contact with air for a long time, which will affect the electrical performance and even lead to waste boards; the concentration of the ink plug holes and the performance technology of the pcb circuit board plug hole screen printing machine will have an impact on the quality. It has a greater impact and will be introduced in detail in the next issue, the article on the decisive factors of the quality of PCB circuit board ink plug holes. Please pay attention to the latest technical articles of Xinjinhui PCB Equipment Network.
2. Plug hole method 2: Aluminum sheet plug hole
Aluminum sheet plugging actually refers to plugging holes in the holes of the aluminum sheet with the help of aluminum sheets during the plugging process. It is different from the ink plugging introduced above. Ink plugging mainly refers to the plugging process using ink; aluminum sheet The purpose of plugging holes is mainly to avoid the phenomenon of oil leakage caused by plugging holes directly, which wastes ink and causes pollution to the PCB board surface, affecting the appearance and quality performance. It is a process method that assists in improving the quality of plugged holes. Xin Jinhui serves as With 20 years of experience in PCB intelligent plugging, screen printing machines and energy-saving leaders, we have developed a series of professional PCB plugging equipment, such as:, PCB line circuit board ink, which has been widely recognized and selected by the top 100 companies in the PCB industry.
3. Hole plugging method 3: Resin plugging hole
Resin plugging and ink plugging have the same principle, that is, resin is replaced by ink, but the PCB plugging equipment used has higher requirements, because the density of the resin is higher, and the plug requires greater pressure and pressure when filling the hole. Precision, such as: Xin Jinhui’s self-developed PCB intelligent fully automatic pressure plugging machine has key technologies such as boosting and locking to achieve full plugging with one knife, high quality and high efficiency; secondly, resin plugging is mainly used for ink plugging to meet the requirements of Failure or ink plugging can easily lead to poor plugging, such as: via plugging holes on multi-layer BGA boards, buried holes in inner HDI, through holes with large thickness of the board, etc. Secondly, if the requirements for resin plugging are high If so, you may need to use more high-end ones.
In this issue, the editor of Xin Jinhui introduces three common plugging methods: ink plugging, aluminum sheet plugging and resin plugging, as well as the characteristics of each plugging method and the recommended PCB plugging machine equipment; the next issue will be Everyone brings “the decisive factor of the quality of PCB circuit board ink plug hole”, please continue to pay attention to Xinjinhui PCB plug hole screen printing dryer equipment network, we will share with you PCB vacuum/pressurization/ink/resin plug hole, text/ , Solder mask pre-baking/text post-baking tunnel oven hot air circulation oven related process technology professional inform
