Mechanical and electrical tolerances
Contour tolerances:
Hole tolerances:
Electrical tolerance
Tolerance for scoring cut (V-cut)
If you have scoring on the outline of the printed circuit board, the following tolerances apply:
solder shorting between traces or unwanted electrical contact with possible loose wires. For its function of helping tolerances Mechanical 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,
It is used to mark component values, part numbers, test points, polarity, etc. Screen printing does not Mechanical tolerances influence the printed circuit and the possible problems that may appear may be slight discolorations due to the high temperatures for gluing the components, so they are only PCB
controlled manner according to a predetermined scheme. 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 tolerances Mechanical circuits. Technology has penetrated more and more areas
