The printed circuit, PCB -printed circuit board- is an important electronic component used in any electronic equipment.
The printed circuit board can be planted or assembled manually or automatically, automatic soldering and automatic inspection of electronic components guarantee the quality of electronic equipment, improve work productivity and reduce costs.
Our printed circuit boards are used for a variety of purposes, safety and surveillance, power supply, telecommunications, automotive electronics, medical appliances and instruments, national defense and industrial equipment, etc.

Printed circuits are widely used in many fields: Consumer goods Military Aerospace Industrial Medical Naval The unprecedented development in recent years of all fields of activity has led to a revolution in the types and models of printed circuits. Technology has penetrated more and more areas of our lives
of the PCB and has the role of a reference indicator for the components on the PCB. Graphics and text on a circuit board's PCB are usually printed with a non-conductive permanent epoxy ink. The color is usually white, although other colors are available: yellow, black, blue, red. printed board Manufacture circuit of Screen printing is used to
can have different colors: green, red, blue, white, black. Only the outer layers circuit printed board of Manufacture need to be covered with solder mask, the inner copper layers are protected by the adjacent substrate layers. The soldering mask soldermask is made of a fluid substance like an ink and is applied in a
