Abstract
A copper-clad plate with magnetic sheets comprises a copper foil layer, an insulating layer and a substrate layer from top to bottom, wherein a plurality of magnetic sheets are arranged on the lower end face of the substrate layer; the utility model discloses a copper-clad plate with magnetic force piece, local set up the magnetic force piece, can adopt magnetism to inhale the fixed electronic component of mode, make arranging of electronic component demolish convenient nimble with the installation, be applicable to multiple use scenes such as LED lamp plate.
Description
Technical Field
The utility model belongs to the technical field of the PCB, concretely relates to copper-clad plate with magnetic force piece.
Background
Along with the development of technology, the application of integrated circuits (PCBs) is more and more extensive, once electronic components on the integrated circuits are fixed on the integrated circuits, the electronic components are difficult to remove and replace, when electronic components of different types and kinds need to be replaced, the electronic components are troublesome, and when the positions of the electronic components need to be moved, the electronic components are more inconvenient.
For example, in the currently used LED lamp, LED lamp beads are welded on a lamp panel, once one or more of the lamp beads are broken (completely or continuously flickers), the whole lamp panel can be repaired only by replacing the whole lamp panel, if the connection between the LED lamp beads and the lamp panel is replaced by a magnetic type (ferromagnetic metal is arranged on the LED lamp beads, and a magnet is arranged on the lamp panel, or vice versa; a circuit on the lamp panel is provided with a plurality of exposed electrical connection points for electrically connecting with the LED lamp beads), the LED lamp beads are quite convenient to disassemble and replace, and for advertising boards and the like needing to be spliced with characters and patterns, the LED lamp beads can be moved to corresponding positions flexibly and variably; in the occasion that needs different illumination luminance, the accessible increases or reduces the quantity of LED lamp pearl and changes illumination luminance, and is very convenient.
SUMMERY OF THE UTILITY MODEL
The utility model aims at providing a copper-clad plate that has magnetic force locally and can adopt the magnetic suction mode to fix electronic component.
In order to solve the technical problem, the utility model discloses a copper-clad plate with magnetic force piece is by last copper foil layer, insulating layer and base plate layer of including down, the terminal surface is equipped with a plurality of magnetic force pieces under the base plate layer.
Preferably, a plurality of blind holes are formed in the lower end face of the substrate layer, and the magnetic sheets are fixed in the blind holes.
Preferably, the blind hole is slightly larger than the magnetic sheet, so that a gap exists between the side edge of the magnetic sheet and the blind hole.
Preferably, the magnetic sheet is bonded and fixed to the lower end surface of the substrate layer.
Preferably, the magnetic sheet is a heat-resistant magnetic material.
Preferably, the substrate layer is a metal substrate or a ceramic substrate.
Preferably, the substrate layer is an aluminum substrate.
The utility model discloses a copper-clad plate with magnetic force piece has following advantage at least:
the utility model discloses a copper-clad plate with magnetic force piece, local set up the magnetic force piece, can adopt magnetism to inhale the fixed electronic component of mode, make arranging of electronic component demolish convenient nimble with the installation, be applicable to multiple use scenes such as LED lamp plate.

Detailed Description
The present invention is further described in detail below with reference to examples so that those skilled in the art can implement the invention with reference to the description.
It will be understood that terms such as "having," "including," and "comprising," when used herein, do not preclude the presence or addition of one or more other elements or groups thereof.
Example 1
As shown in fig. 1, the copper-clad plate with magnetic sheets comprises a copper foil layer 1, an insulating layer 2 and a substrate layer 3 from top to bottom, wherein a plurality of magnetic sheets 4 are arranged on the lower end surface of the substrate layer. The magnetic force sheet is positioned according to the setting position of the electronic element on the copper-clad plate, and the copper foil layer corresponding to the magnetic force sheet is provided with exposed electric connection points, so that part of the electronic element on the copper-clad plate can adopt a magnetic attraction fixing mode, and the copper-clad plate is convenient to detach, convenient to arrange in position and flexible and multipurpose.
A plurality of blind holes 5 are formed in the lower end face of the substrate layer, and the magnetic sheets are fixed in the blind holes.
The blind hole is slightly larger than the magnetic sheet, so that a gap exists between the side edge of the magnetic sheet and the blind hole. The blind hole position is determined according to the setting position of electronic component on the copper-clad plate, and the copper foil layer that the magnetic force piece corresponds department should set up naked electrical connection point, and this makes partial electronic component on the copper-clad plate can adopt the fixed mode of magnetism and inhale, convenient dismantlement and position overall arrangement, and is nimble multi-purpose.
The magnetic sheet is a heat-resistant magnetic material.
The substrate layer is an aluminum substrate.
Example 2
As shown in fig. 2, similar to example 1, the difference is that the magnetic sheet is adhered and fixed to the lower end surface of the substrate layer, so that the magnetic sheet is more conveniently arranged and the production cost is reduced, but the magnetic sheet is arranged in a manner that the magnetic sheet is relatively far away from the electrical connection point of the copper foil layer, and the adsorption force is slightly weak.
While the embodiments of the invention have been disclosed above, it is not limited to the applications listed in the description and the embodiments, which are fully applicable in all kinds of fields suitable for the invention, and further modifications may be readily made by those skilled in the art, and the invention is therefore not limited to the specific details and embodiments shown and described herein, without departing from the general concept defined by the claims and their equivalents.
