Printed circuit board silkscreen
are available: yellow, black, blue, red. Screen printing is used to render useful information on the PCB board that can help users during assembly. It is used to mark component values, part design Projection, CAD numbers, test points, polarity, etc. Screen printing does not influence the printed circuit and the possible problems that may appear may be slight
Methods of using the printed circuit board
of the printed circuit board made in recent years have greatly helped fields such as medicine and aeronautics to benefit from smaller and lighter equipment that has allowed them a high degree of development and Projection, design CAD effectiveness. Today, in our house, almost every electronic device that helps us in the household contains a larger or smaller
Printed circuit soldermask
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 protected by design CAD Projection, the adjacent substrate layers. The soldering mask soldermask is made of a fluid
