In the printed circuit board industry, screen printing machine is an important equipment, which can be divided into full-automatic, semi-automatic and manual equipment. Details are as follows

1. CCD full-automatic screen printing machine: it is a fully automatic online screen printing equipment, which realizes the printing of wet film and white characters on circuit boards through automatic machinery. Positioning is basically through optical alignment. The operator can control the movement of the scraper through the electric control switch or control the equipment through programming. This equipment is characterized by high speed, high positioning accuracy and convenient use. The disadvantage is that the price is expensive and maintenance is relatively difficult. It can adapt to PCB manufacturing with high assembly precision and large scale and large batch.

2. Electric semi-automatic screen printing machine: it is a kind of equipment between manual screen printing machine and full-automatic screen printing machine. It realizes the printing of wet film and white words on road boards through machinery. There are two ways of positioning: complete manual positioning and optical alignment. The operator can control the movement of the scraper through the electric control switch. This equipment is characterized by moderate price and convenient use. The disadvantage is that the speed is slow, the positioning accuracy is not high, and it can not adapt to PCB manufacturing with high assembly accuracy and large batch.

3. Hand printing stand: It is also called "manual silk printing stand" simply. It realizes the printing of wet film and white words on the road board by pure manual means. The advantages are economical price and convenient use. The disadvantage is that the positioning accuracy is poor, and it cannot adapt to the manufacturing of PCB with high assembly density.
