Abstract

The utility model discloses a printed circuit board (PCB) preventing tin-welding short circuit, and the PCB is provided with a main body, wherein the main body is provided with an active board area, a substrate is arranged on the main body to be close to the active board area, and the substrate is in rigid connection with the main body. On the premise of not influencing the structure and inserts of the circuit board, effective excess materials are added by utilizing the rigid connection, so that the badness of the circuit caused by the tin welding perforation can be prevented, and the short circuit between the PCB and elements on the PCB can be effectively prevented.

Description

Prevent the pcb board of soldering short circuit

Technical field

The utility model relates to pcb board commonly used on the electronic equipment, relates in particular to a kind of pcb board that prevents the soldering short circuit.

Background technology

Along with the develop rapidly of electron trade, the trend of electronic product microminiaturization is obvious day by day, and a pcb board is except fixing various little electronic components, and its major function provides being electrically connected each other of various electronic components in addition.Along with the development of information technology, electronic equipment also becomes increasingly complex, and the part that needs is more and more, and circuit and part on the pcb board are also more and more intensive.In the pcb board manufacturing; Pcb board is heat insulation by insulation, also unbending material constitutes substrate, and the tiny line material that can see on the surface is a Copper Foil, and Copper Foil is to cover on the whole plate originally; Part is etched and disposes in manufacture process; The part that stays has just become netted tiny circuit, and these circuits are known as lead, and is used to provide the circuit of part on the pcb board to connect.

Because pcb board and the element that born thereof are more and more littler because the scolding tin perforation, when causing the element welding and pcb board be short-circuited.

The utility model content

The purpose of the utility model is the problem that solves above-mentioned existence, provides a kind of when preventing the element welding and a kind of pcb board that prevents the soldering short circuit of being short-circuited of pcb board.

The purpose of the utility model realizes as follows: a kind of pcb board that prevents the soldering short circuit, have body, and said body is provided with effective plate district, is positioned to close on effective plate district on the said body and be provided with substrate, and said substrate and body are rigidly connected.

Saying further, said substrate are both ends open formula structure or the base material with via structure.

The advantage of the utility model: under the prerequisite that does not influence this body structure of wiring board and plug-in unit, utilizing is rigidly connected increases effective clout, and the circuit that stops the scolding tin perforation to cause is bad, has prevented that effectively the element on pcb board and the plate is short-circuited.

Description of drawings

For the content that makes the utility model is expressly understood more easily,, the utility model is done further detailed explanation, wherein below according to specific embodiment and combine accompanying drawing

Fig. 1 is the utility model structural representation;

Fig. 2 is the structural representation of embodiment 2;

Reference numeral: 1, body, 2, substrate.

Embodiment:

Embodiment 1

See shown in Figure 1ly, a kind of pcb board that prevents the soldering short circuit has body 1, and said body 1 is provided with effective plate district, is positioned to close on effective plate district on the said body 1 and be provided with substrate 2, and said substrate 2 is rigidly connected with body 1; Said substrate 2 is for having the base material of via structure, and when increasing effective clout, the circuit that stops the scolding tin perforation to cause is bad.

Embodiment 2

See shown in Figure 2ly, a kind of pcb board that prevents the soldering short circuit has body 1, and said body 1 is provided with effective plate district, is positioned to close on effective plate district on the said body 1 and be provided with substrate 2, and said substrate 2 is rigidly connected with body 1; Said substrate 2 is the base material of both ends open formula structure, according to the needs of processing, when increasing effective clout, has prevented that effectively the element on pcb board and the plate is short-circuited.

Above-described specific embodiment; Purpose, technical scheme and beneficial effect to the utility model have carried out further explain, it should be understood that the above is merely the specific embodiment of the utility model; Be not limited to the utility model; All within the spirit and principle of the utility model, any modification of being made, be equal to replacement, improvement etc., all should be included within the protection range of the utility model.

Claims
