The most basic purpose of surface treatment is to ensure good solderability or electrical properties. Since natural copper tends to exist in the form of oxides in the air, it is unlikely to remain as original copper for a long time, so other treatments are needed for copper. Although a strong flux c

The PCB industry continues to develop, mainly due to the strength of two aspects. First, the market space of the circuit board industry application industry continues to expand, the communication industry and the automotive industry, and the application of the industrial control industry have been i

1. Line and Pattern: The line is used as a tool for conducting between the originals, and a large copper surface will be designed as a grounding and power layer in addition. The lines and drawings were made simultaneously.2. Holes (Throughhole/via) : The throughhole can enable lines at more than two
