What does PCB footprint mean?

1. PCB terminology Footprint refers to the solder pad.

2. PCB (Printed Circuit Board), the Chinese name du is called printed circuit board {PCB circuit board}, also known as printed circuit board, which is the provider of electrical connection dao for electronic components. Its development has a history of more than 100 years; its design is mainly layout design; the main advantage of using circuit boards is to greatly reduce wiring and assembly errors, and improve the level of automation and production labor rate.

3. Before the advent of PCB, the interconnection between electronic components was done directly by wires. Nowadays, wires exist only for testing applications in the laboratory; printed circuit boards have definitely occupied a position of absolute control in the electronics industry.

Expansion information:

Printed boards have developed from single-layer to double-sided, multi-layer and flexible, and still maintain their respective development trends. Due to the continuous development of high precision, high density and high reliability, continuous reduction in size, cost reduction, and performance improvement, the printed board will still maintain a strong vitality in the future development of electronic equipment.

Summary of domestic and foreign discussions on the future development trends of printed board manufacturing technology are basically the same, that is, towards high density, high precision, fine aperture, fine wire, fine pitch, high reliability, multilayer, high-speed transmission, light weight, The development of thin-type, in terms of production, at the same time, to increase productivity, reduce costs, reduce pollution, and adapt to the development of multi-variety, small-batch production. The technical development level of printed circuits is generally represented by the line width, aperture, and thickness/aperture ratio of the printed board.
