Abstract
The utility model discloses an aluminum product circuit board for aluminum component interconnection, this circuit board have and the aluminum component between the welding combine the characteristics of reinforce, be applicable to circuit, the cable of the interconnection of substituting aluminum component, has improved and has probably reached the reliability with the aluminum component welded.
Description
Technical field
This utility model can lift cable and the combination after aluminum component welding for the improvement to connecting aluminum component cable material
Ability and reliability, the interconnection being particularly well-suited between aluminum component.
Background technology
Because the factors such as cost, weight, chemical property, physical characteristics, what metallic aluminium was universal are applied on electronic component,
Such as：Electric capacity, electrode etc..But the Weldability between aluminum and copper is not good, after welding, solder joint often has the potential risk of fracture.And
Welding between aluminum and aluminum, not only can be by these easier modes of Laser Welding, spot welding or ultrasonic bonding, Er Qietong
Welding between metalloid possesses good adhesion.This utility model is namely based on the background of the above, will connect between aluminum component
Cable, be designed to aluminium wiring board to solve the integrity problem of aluminum component interconnection welding, its manufacturing process is simple, low cost
It is honest and clean.
The content of the invention
The technical problems to be solved in the utility model is to provide that a kind of new weldability between aluminum component is good, manufacturing process
Simply, wiring board with low cost, being adapted to batch micro operations, can substitute the interconnection that traditional copper cable comes for aluminum component, while
Element and cable more preferably, can be formed tight with firm one, possess high reliability by adhesion after welding between similar metal
The characteristics of.
In order to reach above-mentioned purpose of design and requirement, a kind of aluminium line for aluminum component interconnection that this utility model is adopted
Road plate, it is characterized by be formed by stacking with aluminum steel road floor by insulating barrier, the equal naked layer in line layer two sides of welding position.
Insulating barrier is the thin film with insulating properties, is overlying on circuit layer surface as protective layer and possesses certain support and makees
With, it is bonded on line layer, goes out to be open simultaneously for the Position Design that need to be welded or connect, the line layer for exposing.
Line layer uses aluminium foil, forms required circuit using etch process, and which is at least simultaneously coated with insulating barrier, welding
The circuit of the position then equal naked layer in two sides, in order that the circuit for being formed possess certain weldability, reliability, connectivity,
Support ability, the thickness of aluminium foil need to be more than 0.10 mm.
Preferred PI, PET, PE class material of insulating barrier.
The surface of insulating barrier is covered with for bonding adhesive layer with extraneous contact portion.
The insulating barrier of the aluminium wiring board for aluminum component interconnection is made, first using punching press or the mode of cutting, is obtained and institute
The insulating barrier of line matching size is needed, is exposed the welding position of two sides line layer, and is bonded together with the one side of aluminium foil,.So
After reuse wiring board manufacturing process, the layout using light shifting process, needed for being etched on the aluminium foil for post insulating barrier
Shape, and pass through automatic visual inspection instrument（AOI）Or the mode of visual inspection checks the quality of gained circuit（Whether there is out the problem of short circuit）.
According to design needs, aluminum line layer does not paste the other one side of insulating barrier, it is also possible to which bond insulating barrier, and hot pressing is reinforced so that aluminum
All protected by insulating barrier on the two sides of circuit, it is to avoid when in use exposed line layer touch other electronic components cause it is short
Road.Finally according to design requirement, the word needed on silk-screen on gained aluminium wiring board.

[specific embodiment]
Embodiment one：
A kind of aluminium wiring board for aluminum component interconnection, as Figure 1-3, including：Line layer, insulating barrier；The circuit
Layer is that, by the circuit made by etch process, which has one side to cover described insulating barrier using aluminium foil；The insulating barrier possesses
Certain autohension and supportive, are fitted in the structure of gained on line layer, can play the support to line layer and make with isolation
With.
Wherein, aluminium foil used by described line layer, in order that the circuit for being formed possesses certain weldability, reliability, company
Connecing property, enabling capabilities, the thickness of aluminium foil need to be more than more than 0.10mm.Shifted by light and etch process, form institute on aluminium foil
The circuit for needing, that is, the line layer needed for being formed.
Described insulating barrier, before line layer is attached, first passes through punching flow process, and the position that line layer needs welding is opened
Mouth exposes, and after attaching line layer, then by way of hot pressing, strengthens the adhesion with line layer.
Concrete production procedure is as follows：
Sawing sheet/punching insulating barrier cleaning aluminium foil laminating insulating barrier pressing coating photosensitive layer pair
Position/exposure imaging/etching checks silk-screen character
In the present embodiment, because aluminium foil is softer, therefore by the enabling capabilities of insulating barrier forming certain intensity, and
After being welded on components and parts, by insulating barrier come protection circuit, it is to avoid form the problem of short circuit with components and parts.
Embodiment two：
A kind of aluminium wiring board for aluminum component interconnection, as shown in Fig. 2,4,5, including：Line layer, insulating barrier；The line
Road floor is that, by the circuit made by etch process, which has two sides to cover described insulating barrier using aluminium foil；The insulating barrier
Possess certain autohension and supportive, be fitted on line layer the structure of gained, can play the support to line layer with every
Act on absolutely.
Wherein, aluminium foil used by described line layer, in order that the circuit for being formed possesses certain weldability, reliability, company
Connecing property, enabling capabilities, the thickness of aluminium foil need to be more than more than 0.10mm.Shifted by light and etch process, form institute on aluminium foil
The circuit for needing, that is, the line layer needed for being formed.
