There are many forms of matter, such as solid, liquid, gas, plasma and so on. We usually call materials with poor conductivity, such as coal, artificial crystal, amber, ceramics and so on, insulators. Metals with good conductivity, such as gold, silver, copper, iron, tin and aluminum, are called conductors. The material between conductor and insulator can be simply called semiconductor. Compared with conductors and insulators, the discovery of semiconductor materials is the latest. Until the 1930s, when the purification technology of materials was improved, the existence of semiconductors was really recognized by the academic community.

In 1936, Austrian Paul Eisler first used printed circuit board in radio. In 1943, Americans mostly applied this technology to military radios. In 1948, the United States officially recognized that this invention can be used for commercial purposes. Since the mid-1950s, printed circuit boards have been widely used.

The term "plug hole" is not a new term for the printed circuit board industry.

Our common computer boards and cards are basically epoxy resin glass cloth based double-sided printed circuit boards. One side is the plug-in components, and the other side is the welding surface of the component feet. It can be seen that the welding points are very regular.

HONTEC thanks everyone for your continued support and hopes that we can have better cooperation in the future.
