Abstract
The utility model relates to a printed circuit board structure for an automobile electrical appliance box, comprising solder mask layers and circuit layers, wherein, at least three circuit layers are arranged in a printed circuit board, and a partition insulation layer is arranged between each two circuit layers; and the upper surface of the upmost layer and the lower surface of the bottommost layer are provided with solder mask films. The multilayer printed circuit board structure is adopted in an automobile electrical appliance box, so the all layers of circuits are mutually separated, the unnecessary contact with each other is avoided, and the function of the printed circuit board is more stable and more reliable. As only one printed circuit board is used, components, such as soldering support columns and plastic support columns, and the like, are reduced, and relevant working procedures, such as soldering, cleaning and inspection, and the like, are reduced. Thus, the production cost is reduced greatly, the production efficiency is enhanced effectively, and the size of the electrical appliance box is more compact.
Description
Technical field

The major function of automobile electrical equipment box is to each power consumption equipment power distribution of automobile and relies on relay, safety plate etc. to control and protect each power consumption equipment of automobile, wire harness circuit.Undertaking automobile function realize and prevent since the secondary vehicle that power failure (short circuit, overload) causes, personal safety accident in the important function of possible trouble.Pcb board structure electrical equipment box is a class important in the automobile electrical equipment box.
At present, automobile electrical equipment box is because the power consumption equipment of the function that need control and protection is more, more and more to integrated, miniaturization, precise treatment development.And pcb board has embodied the design grounding in basic skills of production firm to automobile electrical equipment box.The PCB number of plies is many more, designs complicatedly more, and it is accurate more to do manual work.Stability is just good more.Pcb board not only supports the componentry of whole electrical equipment box, and the stability of electrical equipment box is played crucial effects, is the soul of electrical equipment box workmanship quality.Good electrical equipment box wants that strong " physique " arranged, and accurate pcb board is essential.
Pcb board in the automobile electrical equipment box adopts the structure at the two-sided or two plates of veneer four sides mostly now, adopts support column to be fixed together between each layer circuit layer.This pcb board structure causes easily between each layer circuit and contacts with each other, and causes the pcb board unstable properties, and the electrical equipment box body is long-pending greatly, production cost is higher, production efficiency is low.
The utility model content
The technical problems to be solved in the utility model is the technical problem that volume is big, production cost is higher, production efficiency is low that the pcb board in the existing automobile electrical equipment box exists; Provide a kind of and can effectively realize the car electrics kit function, each layer circuit is separated from each other, and avoided unwanted contact, the function of pcb board is more reliable and more stable, and make the electrical equipment box reduce volume, reduce production costs the pcb board structure in the automobile electrical equipment box of enhancing productivity.
For solving the problems of the technologies described above, the utility model adopts following technical scheme:
The pcb board structure that is used for automobile electrical equipment box of the present utility model comprises solder mask and circuit layer, and wherein, design has at least three layers of circuit layer in a pcb board; Be provided with the partition insulating barrier between every two-tier circuit, on the lower surface of the upper surface of last layer and basecoat, be provided with soldering-resistance layer.
In the pcb board of the present utility model, can carry out the connection of different modes by the structure of through hole or buried via hole or blind hole between the multilayer circuit.All kinds of plugs of welded and installed, socket, conducting strip, electric components etc. on pcb board.
In automobile electrical equipment box, adopt multi-layer PCB board structure of the present utility model, each layer circuit is separated from each other, avoided unwanted and be in contact with one another, more make the function of pcb board more reliable and more stable.And owing to only use a pcb board, reduced parts such as welding support column, plastic support post, reduced operations such as associated welds, cleaning, check.Production cost is greatly reduced, and production efficiency is effectively provided, and the electrical equipment box body is long-pending also more small and exquisite.

Embodiment
Embodiment 1
As shown in Figure 1, at first carry out circuit design according to electrical schematic diagram, design has four layers of circuit layer 4 in a pcb board; Four layers of circuit layer divide from top to bottom in order and are followed successively by one～four layer, are provided with between every two-tier circuit and cut off insulating barrier 3.On ground floor and the 4th layer below be provided with solder mask 2.
Can carry out one, two layer and three, four layers in the manufacturing process respectively, then two boards be glued one with dielectric resin material, so just form a pcb board 6 with four layers of circuit.Also can according to circumstances do two, three layers earlier, then one, four layer be bonded together with two, three layers.
Pcb board of the present utility model in addition can be made into the pcb board of the circuit layer that comprises five layers or six layers or other number of plies.
Owing between different layers, according to circumstances need circuit to connect,, the corresponding copper cash of the circuit layer of upper-lower position to getting up, is allowed hole wall band copper so before the bonding multiple plate, also need boring.Carry out the hole then and electroplate, allow the hole conducting, form plated-through-hole 7, so just be equivalent to lead circuit has been together in series.Can adopt the mode of buried via hole and blind hole to be connected the circuit of different layers, blind hole is which floor internal circuit is connected with surface circuit, must not penetrate whole plank, and buried via hole then only connects inner circuit.On outmost circuit layer, brush soldering-resistance layer (also being anti-welding lacquer) at last.
After the pcb board design machines, all kinds of plugs 5, socket 1, conducting strip, electric components etc. are welded on the corresponding welding hole of reserving on the pcb board.Thereby the realization expected effect is as Fig. 2.
In the utility model, the connected mode of each circuit layer can following different connected mode connect:
As shown in Figure 3, each circuit layer adopts the mode of through hole to be connected, and first, second, third and fourth circuit is connected.
As shown in Figure 4, each circuit layer adopts the mode of buried via hole to connect, and second circuit layer and tertiary circuit layer are connected.
As shown in Figure 5, each circuit layer adopts the mode of blind hole to connect, and first circuit layer and second circuit layer are connected.
As shown in Figure 6, at first carry out circuit design according to electrical schematic diagram, design has three layers of circuit layer 4 in a pcb board; Three layers of circuit layer divide from top to bottom in order and are followed successively by one～three layer, are provided with between every two-tier circuit and cut off insulating barrier 3.On ground floor and the 4th layer below be provided with solder mask 2.Three layers of circuit layer adopt the mode of blind hole to connect, wherein ground floor and second layer circuit communication.In the present embodiment, also can adopt the mode of through hole or buried via hole to connect between the circuit layer.
