Types of printed circuit board
circuit made of a thin polyamide of 0.1-0.3 mm with a rigid printed circuit on an FR4 substrate. These printed circuits are used more and more lately, having the advantage of their flexibility. A PCB may have an inscription or screen printing that imprimat aurit circuit identifies components, test points or identification text. Screen printing
Printed circuit soldermask
electrical contact with possible loose wires. For its function circuit imprimat aurit of helping to prevent solder shorts, the coating is called a solder mask. Soldermask is generally green in color but can have different colors: green, red, blue, white, black. Only the outer layers need to be covered with solder mask, the inner copper layers are
Methods of using the printed circuit board
reliable electrical connections between the component terminals in a controlled manner according to a predetermined scheme. Printed circuits aurit circuit imprimat 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
