Printed circuit board PCB printing equipment at a glance

Fully automatic placement machine: It is a fully automated online placement device. It is a device that accurately places surface mount components to a fixed position through an automatically moving placement head. It has mechanical alignment and vision positioning. There are several methods for alignment and laser alignment. This equipment is an indispensable key equipment in SMT production.

Manual placement machine: It is completely purely manual, using vacuum nozzles and guide rails to achieve the placement of components. The advantages are economical price and convenient use. The disadvantage is that the positioning accuracy is poor and the speed is slow, and it cannot adapt to the PCB assembly with higher assembly density. This equipment is more suitable for R & D and production of small batches and many varieties of scientific research institutions, research institutes, various electronic laboratories and so on.

Fully automatic screen printing machine: It is a fully automated online screen printing equipment, which realizes the leakage printing of solder paste or patch glue through automated machinery. Positioning is basically through optical alignment, the operator can control the movement of the scraper through the electronic control switch or control the device through programming. This equipment is characterized by high speed, high positioning accuracy and easy to use. The disadvantage is that it is expensive and relatively difficult to maintain. It can adapt to PCB assembly with high assembly precision and large-scale mass production.

Semi-automatic screen printing machine: It is a device between manual screen printing machine and automatic screen printing machine. It uses machinery to realize the missing printing of solder paste or patch glue. There are two methods of positioning: manual positioning and optical alignment. The operator can control the movement of the scraper through the electronic control switch. The characteristic of this equipment is that it is affordable and easy to use. The disadvantage is that the speed is slow, the positioning accuracy is not high, and it cannot be adapted to PCB assembly with high assembly accuracy and large-scale mass production.

Manual screen printing machine: It is also simply called "manual screen printing station", it completely realizes the leakage printing of solder paste or patch glue by purely manual method. The advantages are economical price and convenient use. The disadvantage is that the positioning accuracy is poor, and it cannot adapt to some PCB assembly with higher assembly density.
