Abstract

The utility model relates to a circuit board, in particular to a board combining softness and hardness. A board combining softness and hardness for a printed circuit comprises two layers of hard boards and a layer of soft board. The soft board is located between the two layers of hard boards. At least one V-shaped groove is cut out on the outer layer of each hard board and at least one V-shaped groove is cut out on the inner layer of each hard board. The beneficial effects of the board combining softness and hardness for the printed circuit are that: the board has a simple structure and a convenient technology; the inner layer of the board cannot be contaminated by chemical solutions; no corrosion on the circuit can be caused; the product quality of the circuit board is guaranteed; the production efficiency is high; and the production cost is low.

Description

A kind of hard and soft board for printed circuit
Technical field
The utility model relates to a kind of circuit board, particularly a kind of hard and soft board.
Background technology
At present, the pcb board of printed circuit often uses hard plate, and the advantage of hard plate is that distortion is little, and printed circuit is clear, but also there are some problems in hard plate, and is large such as hard plate stress, is applied in the electronic device, and electrical heating affects useful life.
The utility model content
The purpose of this utility model is to provide a kind of hard and soft board of printed circuit.
The purpose of this utility model is achieved through the following channels:
A kind of hard and soft board for printed circuit is comprised of two-layer hardboard and one deck soft board, and soft board is in the middle of two-layer hardboard; Described hardboard skin has at least one place to cut out the V-type groove, and described hardboard internal layer has at least one place to cut out the V-type groove.
Preferably, the degree of depth of the V-type groove of described hardboard skin and hardboard internal layer is the 30-60% of hardboard thickness.
The beneficial effects of the utility model are:
Simple in structure, technique is convenient, and internal layer can not polluted by chemical medicinal liquid, can not cause the corrosion to circuit, has guaranteed the product quality of circuit board, and production efficiency is high, and production cost is low.
Description of drawings
Below in conjunction with accompanying drawing the utility model is described in further detail:
Fig. 1 is the utility model structural representation;
1 is hardboard, and 2 is soft board, and 3 is the V-type groove.
Embodiment
As shown in Figure 1, a kind of hard and soft board for printed circuit of the utility model is comprised of two-layer hardboard and one deck soft board, and soft board is in the middle of two-layer hardboard; Described hardboard skin has at least one place to cut out the V-type groove, and described hardboard internal layer has at least one place to cut out the V-type groove.
The degree of depth of the V-type groove of hardboard skin and hardboard internal layer is the 30-60% of hardboard thickness.
