Abstract

The utility model discloses a flexible shapable circuit board and relates to the field of printed circuit boards. The flexible shapable circuit board comprises a baseplate, an insulating gel layer and a circuit pattern layer; the insulating gel layer and the circuit pattern layer are arranged on one side of the baseplate, at least one groove for facilitating shaping of the baseplate is arranged on the other side of the baseplate, and the baseplate is made of stretchable and bendable metal. The part of the groove on the baseplate is the part with relatively weak stress actually, thereby playing a buffering role when bending operation is performed on the circuit board and avoiding fracture of the circuit board. Therefore, the flexible shapable circuit board is convenient to shape so as to be correspondingly assembled with various different curved surface carriers, thereby not only reducing the cost and reducing the assembly process steps, but also accelerating the assembly.

Description

A kind of circuit board of flexible mouldable

Technical field

The utility model relates to the printed circuit board field, particularly relates to a kind of circuit board of flexible mouldable.

Background technology

Traditional printed circuit board generally comprises substrate and is attached to being used on the substrate installs circuitous pattern (if the multilayer circuit board of components and parts, then on each layer, corresponding circuitous pattern is arranged all), its manufacture method is, the metal level that is attached on the substrate forms circuitous pattern (if multilayer circuit board after image transfer, then on each layer, corresponding circuitous pattern is arranged all), no matter be single layer board or multilayer circuit board, all be planar structure traditionally, can not carry out significantly bending operation (when installing).And carry out the circuit board of bending operation for needs, generally adopt flexible electric circuit board (being FPC) to be electrically connected traditionally; Yet the anti-exactly bad mechanical property of a significant drawbacks of traditional flexible electric circuit board and do not have the heat conduction function, though can utilize the method that increases stiffening plate to strengthen its anti-machine capability and heat conduction, but, this has not only increased the part of assembling, also increase the operation of assembling and taken additional space, make small product size become big, this will certainly influence reliability of products, so how, make circuit board under the situation that does not need stiffening plate, both had suitable machine capability and heat conductivility, can carry out significantly bending operation again, become the direction of industry exploitation.

The utility model content

Technical problem to be solved in the utility model is the above-mentioned deficiency at prior art, a kind of mechanical performance simple in structure, anti-and good heat conductivity is provided and can carries out the significantly circuit board of the flexible mouldable of bending operation.

To achieve these goals, the utility model adopts following technical scheme.

The circuit board of a kind of flexible mouldable of the utility model comprises substrate, insulation glue-line and circuitous pattern layer; Make insulation glue-line and circuitous pattern layer on the one side of substrate, be shaped on the groove of being convenient to moulding at least together on the another side of substrate.

Technique scheme is further elaborated:

Described groove on the substrate can form by machine cuts, and the width that described groove is cut and the degree of depth can decide according to the thickness of substrate, but substrate is not cut off.Distance between the adjacent trenches on the substrate can decide according to the thickness of substrate.

The material of making described substrate for stretching or/and the metal material of energy bending, as copper, or aluminium, or iron, or stainless steel etc.

The circuitous pattern layer of the circuit board of described a kind of flexible mouldable is so-called single face circuit board for one deck only, can be so-called single face multilayer circuit board for multilayer also.

The utility model also comprises the steps: after making the circuitous pattern layer

Do not make at substrate that the mode by machine cuts forms at least one groove separated by a distance on the side of insulation glue-line and circuitous pattern layer.And after described groove was finished, substrate can carry out significantly bending operation, installed with carrier with convenient.

Because the substrate of the circuit board of the flexible mouldable that the utility model provides can carry out significantly bending operation, therefore can produce following beneficial effect:

1, the circuit board of a kind of flexible mouldable of the utility model, groove position on the substrate is actually the relative weak part of stress, thereby when circuit board is bent operation, played the effect of buffering and do not fractureed, so the utility model can make things convenient for moulding with the corresponding assembling of various curved surface carrier, so not only reduce cost, reduced assembly process, and accelerated the speed of assembling.

2, the utility model is made the metal (as copper, aluminium, iron, stainless steel etc.) that the material employing can stretch, energy is crooked of described substrate, so its mechanical performance and heat conductivility are fine, thereby has improved reliability of products.

3, the circuit board of a kind of flexible mouldable of the utility model, its technological process is simple, and the flexible circuit board that utilizes this method to produce only needs to cut out the effect that at least one groove just can reach flexible operation on substrate own, also can reduce the overall weight of circuit board, and make its structure simpler.

4, the circuit board of a kind of flexible mouldable of the utility model, can be applicable to any electronic product and any LED or OLED lighting product, for the LED carrier of different curve angle, the utility model has satisfied the light configuration of LED especially and has enriched the irradiation angle of LED.

Embodiment

Below, introduce embodiment of the present utility model.

As shown in Figure 1 to Figure 3: the circuit board 05 of a kind of flexible mouldable of the utility model, comprise substrate 01, insulation glue-line 02 and circuitous pattern layer 03, make insulation glue-line 02 and circuitous pattern layer 03 on the one side of substrate 01, be shaped on the groove 04 of being convenient to moulding at least together on the another side of substrate 01.

Groove 04 on the described substrate 01 can form by machine cuts, and the width that the groove 04 on the substrate 01 is cut and the degree of depth can decide according to the thickness of substrate 01, but substrate 01 is not cut off.Distance between the adjacent trenches 04 on the substrate 01 can decide according to the thickness of substrate 01.
