Description
Technical Field
The utility model belongs to the technical field of the PCB, concretely relates to formula copper-clad plate is inhaled to magnetism.
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 formula copper-clad plate is inhaled to magnetism includes copper foil layer, insulating layer and base plate layer by last under to, seted up a plurality of through-holes on the base plate layer, be equipped with the magnetic force piece in the through-hole, the magnetic force piece up end is not higher than base plate layer up end.
Preferably, the through hole is slightly larger than the magnetic sheet, so that a gap exists between the side edge of the magnetic sheet and the through hole.
Preferably, the through hole is in a column shape with uniform upper and lower parts, and the magnetic sheet is adhered and fixed with the insulating layer or the inner wall of the through hole.
Preferably, the through hole is in an inverted semi-conical shape or a trapezoidal shape, and the magnetic sheet is matched with the through hole in shape.
Preferably, the magnetic sheet is fixed to the insulating layer or the inner wall of the through hole by adhesion.
Preferably, the magnetic sheet is movably disposed in the through hole.
Preferably, the magnetic sheet is a heat-resistant magnetic material.
Preferably, the substrate layer is a metal substrate or a ceramic substrate.
Further, the substrate layer is an aluminum substrate.
The utility model discloses a formula copper-clad plate is inhaled to magnetism has following advantage at least:
the utility model discloses a formula copper-clad plate is inhaled to magnetism, and local sets up the magnetic force piece, can adopt magnetism to inhale the fixed electronic component of mode, makes arranging and installing of electronic component demolish convenient nimble, is applicable to multiple use scenes such as LED lamp plate.

The reference numbers in the figures are: 1-copper foil layer, 2-insulating layer, 3-substrate layer, 4-through hole and 5-magnetic sheet.
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 figure 1, a formula copper-clad plate is inhaled to magnetism, by last copper foil layer 1, insulating layer 2 and base plate layer 3 of including down, a plurality of through-holes 4 have been seted up on the base plate layer, are equipped with magnetic force piece 5 in the through-hole, and the magnetic force piece up end is not higher than base plate layer up end. The position of the through hole is determined according to the arrangement position of an electronic element on the copper-clad plate, and the copper foil layer corresponding to the magnetic force sheet is provided with an exposed electric connection point so as to be electrically connected with the electronic element. This makes partial electronic component on the copper-clad plate can adopt the fixed mode of magnetism, convenient dismantlement and position overall arrangement, and is nimble multi-purpose.
The through hole is slightly larger than the magnetic sheet, so that a gap exists between the side edge of the magnetic sheet and the through hole. The electronic component during operation generates heat, and the magnetic force piece is very close to electronic component, can produce comparatively frequent expend with heat and contract with cold inevitably, consequently, reserves certain space allowance as the contraction joint, can prevent that the magnetic force piece is broken or the through-hole is impaired, and the magnetic force piece is packed into in the through-hole when also being more convenient for produce simultaneously, improves production efficiency.
The through hole is in a column shape with uniform upper and lower parts, and the magnetic sheet is fixedly bonded with the insulating layer or the inner wall of the through hole.
The magnetic sheet is a heat-resistant magnetic material. When the temperature is too high, the magnetism of the magnetic sheet is reduced or completely lost, so the upper limit of the temperature value of the pins of the electronic component and the problem of heat dissipation need to be considered.
The substrate layer is an aluminum substrate.
Example 2
As shown in fig. 2, similar to embodiment 1, it is different in that the through hole is an inverted semicircular cone shape, and the magnetic sheet is adapted to the shape of the through hole. The inverted semicircular conical through hole can prevent the magnetic sheet from falling from the through hole.
The magnetic force sheet is movably arranged in the through hole. The magnetic sheet is packaged in the through hole, fixing is not needed, the using effect cannot be reduced, the magnetic sheet has certain moving allowance in the through hole, the magnetic sheet is placed into the through hole when production is facilitated, production cost can be reduced, and production efficiency is improved.
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.
