Technical Field
The utility model belongs to the technical field of circuit boards, and particularly relates to a circuit board with more reliable connection.
Background
The circuit boards of the circuit board are classified into three major categories, i.e., a single-sided board, a double-sided board, and a multilayer circuit board, according to the number of layers. First, a single panel, on the most basic PCB, the components are concentrated on one side and the wires are concentrated on the other side. Such PCBs are called single-sided circuit boards because the conductors are present on only one side thereof. The single panel is generally simple to manufacture and low in cost, but has the disadvantage that the single panel cannot be applied to a complex product. The double-sided board is an extension of a single-sided board, and is used when a single-layer wiring cannot meet the requirements of an electronic product. The two sides are coated with copper and wires, and the circuit between the two layers can be conducted through the holes to form the required network connection. The multilayer board refers to a printed board having three or more conductive pattern layers laminated with an insulating material therebetween at intervals, and the conductive patterns therebetween are interconnected as required. The multilayer circuit board is a product of the development of electronic information technology in the directions of high speed, multifunction, large capacity, small volume, thinning and light weight. The circuit board is classified into a Flexible Printed Circuit (FPC), a rigid Printed Circuit (PCB) and a Flexible Printed Circuit Board (FPCB) according to characteristics. But the connection of the circuit board may fail in certain specific situations.
