Description

Clamping type circuit board

Technical Field

The utility model relates to the field of circuit boards, in particular to a clamping type circuit board.

Background

The circuit boards are classified into three major categories, namely single-sided boards, double-sided boards and multi-layer circuit boards, according to the number of layers.

Such a PCB is called a single-sided circuit board because the wires are present on only one side thereof. Single panel is generally simple to manufacture and low cost, but has the disadvantage of not being applicable to products that are too complex.

The double panel is an extension of a single panel, and is used when a single wiring layer cannot meet the needs of the electronic product. The copper-clad wiring is arranged on both sides, and the wiring between the two layers can be conducted through the via hole so as to form the required network connection.

The multi-layer board is a printed board having three or more conductive pattern layers laminated with insulating materials therebetween at a distance, and conductive patterns therebetween being interconnected as required.

However, during the screwing process of the screw in the screw tightening mode, the assembling workers with different working experiences hold different screwing force;

when the screw is screwed in too deeply, the circuit board is extruded by the screw, the pressure is too large, and damage occurs;

when the screw is screwed in too shallow, the circuit board is easy to break away.
