Description

Electroplax structure suitable for car light fills copper heat dissipation

Technical Field

The utility model relates to a printed circuit board technical field, in particular to electroplax structure suitable for car light fills out copper heat dissipation.

Background

Printed circuit boards (PCB boards), also known as printed circuit boards, are providers of electrical connections for electronic components. Its development has been over 100 years old; the design of the method is mainly layout design; the circuit board has the main advantages of greatly reducing errors of wiring and assembly, and improving the automation level and the production labor rate.

Since printed circuit boards are not typical end products, they are somewhat confusing in the definition of names such as: the motherboard for a personal computer is called a motherboard and cannot be directly called a circuit board, and although the circuit board exists in the motherboard, the motherboard is different from the motherboard, so that the two aspects cannot be said to be the same when evaluating the industry. For another example: because of the integrated circuit components mounted on the circuit board, the news media is called an IC board, but it is not substantially identical to a printed circuit board. By printed circuit board we generally say bare board-i.e. a circuit board without upper components.

With the development of the automobile industry and the deepening of the energy-saving concept, the automobile lamp is increasingly adopting an LED lamp. The LED lamp can not be used without a corresponding printed circuit board. In the actual use process, the lamp group adopted by the vehicle lamp has higher power and serious heating, and the existing circuit board has poor heat dissipation due to the structures such as an insulating layer and the like, so that the loss is serious after long-term use, and the vehicle lamp is not suitable for application on the vehicle lamp.

SUMMERY OF THE UTILITY MODEL

In view of the unable high-power use that is applicable to the car light of above-mentioned current circuit board, it is not good to cause the radiating effect, and then the influence is used, causes the problem of loss, the utility model aims to solve the technical problem that a be applicable to the car light and fill out the radiating electroplax structure of copper is provided, fills out the copper technology through drilling, with the car light direct access to copper base plate layer, does benefit to heat transfer heat dissipation, respond well, is suitable for powerful circuits such as car light.

The technical scheme of the utility model as follows: the utility model provides an electroplax structure suitable for car light is filled out copper and is dispelled heat, includes the copper substrate layer, the upper surface on copper substrate layer is provided with the insulating layer, the upper surface of insulating layer is provided with the circuit layer, the top on circuit layer is provided with LED lamp pearl, LED lamp pearl with the circuit layer switches on, it has a plurality of through-holes to bore on the insulating layer, the copper post is equipped with to the through-hole intussuseption, the one end of copper post is connected to on the copper substrate layer, the other end contacts LED lamp pearl.

Further, preferably, the copper substrate layer and the copper pillar are both made of red copper.

Further, preferably, a solder resist layer is provided on the wiring layer.

Further, preferably, a tin paste layer is arranged around the LED lamp bead.

Further, preferably, the number of the through holes is three, and correspondingly, the number of the copper pillars is also three.

Has the advantages that: the utility model discloses think about novelty, reasonable in design, and convenient to use, the utility model provides a be applicable to the car light and fill out radiating electroplax structure of copper, fill out the copper technology through drilling, with the car light direct access to copper base plate layer, do benefit to the heat dissipation that conducts heat, respond well, be suitable for powerful circuits such as car light.

Detailed Description

The invention will be further explained with reference to the following figures and examples:

as shown in fig. 1 and 2, the electric board structure suitable for the car lamp copper filling and heat dissipation has a copper substrate layer 1, an insulating layer 2 is arranged on the upper surface of the copper substrate layer 1, a circuit layer 3 is arranged on the upper surface of the insulating layer 2, an LED lamp bead 4 is arranged above the circuit layer 3, the LED lamp bead 4 is communicated with the circuit layer 3, a plurality of through holes 2a are drilled in the insulating layer 2, copper columns 5 are filled in the through holes 2a, one ends of the copper columns 5 are connected to the copper substrate layer 1, and the other ends of the copper columns contact the LED lamp bead 4.

The utility model discloses in, copper substrate layer 1 plays the effect of support as basic physical layer, and it is connected with LED lamp pearl 4 through copper post 5, transmits copper substrate layer 1 with the heat that LED lamp pearl 4 gived off through copper post 5 on, realizes the heat dissipation, and is respond well. The insulating layer 2 serves to separate the wiring layer 2 and the copper base material layer 1 from each other and prevent them from being short-circuited. In specific implementation, the through hole 2a is formed by laser drilling, the insulating layer is drilled, the insulating layer is LED into the copper substrate layer 1, then the copper column 5 is filled, and the LED lamp bead 4 is arranged after the copper column 5 is filled.
