Why do PCB board making holes need to be plugged? Conductive holes are also known as via holes. In order to meet customer requirements, the circuit board via holes must be plugged. After a lot of practice, the traditional aluminum plug hole process is changed, and the circuit board surface solder mask and plug hole are completed with white mesh. Stable production and reliable quality.

The production of circuit boards is a tedious process, requiring multiple processes to make a complete circuit board. If there is an error in some process production, it will lead to the production of circuit board products that do not meet the requirements. For example, the common PCB circuit board disconnection and open circuit problem will directly affect the function realization of the circuit board. Below, Shenzhen VIASION Electronic Technology Co., Ltd. will explain in detail the reasons for the circuit board open circuit caused by each production process.

The circuit board industry has windows in many manufacturing processes. It is a professional term for this industry, mainly referring to solder mask opening: using film to open the window, the PAD that needs to be soldered or dissipated is exposed to the green Outside the oil layer, in order to meet

Shenzhen VIASION Electronic Technology Co., Ltd. specializes in providing overall PCBA electronic manufacturing services, including one-stop services from upstream electronic components procurement to PCB manufacturing, SMT chip processing, DIP plug-in processing, PCBA testing, and finished product

Shenzhen Honglijie has its own SMT chip factory, which can provide SMT chip processing services for the smallest package 0201 components. Next, I will introduce the precautions for the use of SMT processing patch adhesive.

There are many vias on double-sided boards and multi-layer boards. Many board vias are handled differently. There are generally three types: via hole opening, via hole cap oil, and via hole plug oil. What is the difference between them? , The following editor will introduce in detail.

The welding process of the circuit board is an important part of the circuit board manufacturing process. When the circuit board is welded, it will often happen that the welding fails or the copper foil of the circuit board is damaged. Therefore, it is necessary to master certain skills when solderi

What are the benefits of PCB puzzle?1. Convenient production: Some PCBs are too small in size to meet the requirements of SMT fixtures, so it takes several PCBs to put together before chip production.2. Cost saving: some circuit boards have special shapes and different shapes, and the area of the PC

What are the requirements for the spacing of printed circuit board wires? The editor believes that the distance between adjacent wires must meet electrical safety requirements, and in order to facilitate operation and production, the distance should be as wide as possible. The minimum distance must
