Description
Technical field
The present invention relates to a kind of manufacture field of printed circuit board, it is specifically a kind of not only there is good environmental-protecting performance but also
Possesses the method that the application calixarenes of excellent quality stability processes printed circuit board.
Background technology
As economic continues to develop, printed circuit board is also increasingly wide in the application of the industries such as household electrical appliance, industrial electronic
It is general.Because printed circuit board has processing cost, extremely strong industrial repeatability, automaticity and life that electronic product can be greatly reduced
Efficiency advantage higher is produced, so it is favored by vast electrical equipment, electron trade producer deeply.However, existing printed circuit board
There are two great technological deficiencies in production process.First, traditional printed circuit board is generally processed using Subtraction method, its
Mainly it is made up of operations such as cleaning, press mold, development, etching and stripings.Due to the Reusability industrial chemicals on base material plate body, because
And the environmental contaminants of substantial amounts of heavy metal, high concentrated acid, alkali etc. can be produced in the process of printed circuit board.When above-mentioned
When pollutant is directly discharged toward the external world, the ecological environment around its meeting heavy damage, so traditional printed circuit board production category
Heavily contaminated processing industry.Second, the technique of traditional Subtraction method production printed circuit board (PCB) can not only consume substantial amounts of metal money
Source, can also consume the substantial amounts of energy, and need to carry out environmental protection treatment to waste material in following process.So, Subtraction method adds
Work printed circuit board is a kind of industry of labour's highly dense, in addition to it is more the step of there is whole processing,
Also need to carry out a certain degree of staff operation in processing, cause the production cost of printed circuit board (PCB) all the time can not significantly under
Drop, and its processing efficiency is relatively low.
In order to solve the problems, such as that pollutant discharge amount is larger, the silk-screen printing technique of circuit board is occurred in that in the market.
It utilizes printing plate that the line map of electrically conductive ink is printed to substrate, and small copper particle is solidificated in electrically conductive ink by plating
On, so as to form the conducting wire on substrate.As Chinese patent literature CN102612269A discloses a kind of all print printing electricity
The preparation method of road plate, it utilizes the principle of silk-screen printing that the line map that electrically conductive ink is constituted is printed to substrate, and passes through
Electroplating line figure makes copper particle adhere on line map, to form conductive circuit diagram on substrate.Although the method can be from one
Determine to solve the problems, such as that pollutant is largely discharged in degree, but, although although plating belongs to electrochemical process, copper particle is still
It is to realize that it is fixed on substrate by the way of physical adherence, thus adhesive force of the copper particle on substrate is relatively low.Meanwhile, copper
Simple substance can be directly exposed in the external world when sticking to substrate, cause the circuit of circuit board to be easy to occur aoxidizing come off with copper particle
Situation, so as to considerably increase the impedance of circuit.
In fact, when in the manufacturing process of printed circuit board, occurring the feelings of conducting wire broken string due to manufacturing deficiency
Condition often occurs.Traditional solution is that printed circuit board is placed on independent benefit line machine, first removes the protection on circuit
Oil, then strikes off the copper particle around at broken string, then carries out mending line operation.But, traditional benefit line method equally occurs benefit
The copper particle relatively low problem of adhesive force on substrate again at line, and mend the operation of line and need individually to carry out, so as to cause printed circuit
The processing efficiency of plate declines to a great extent.
Additionally, in the comparing of conductance, silver has the electric conductivity more more outstanding than copper.But due to Conventional abatement method and
Stencil can cause the waste of a large amount of metal materials, and silver belongs to precious metal, so it fails in printed circuit all the time
It is widely used in the processing of plate.Therefore, how to manufacture it is a kind of both possessed excellent conductance, can effectively control it to be processed into again
This silver wire circuit board, is always the significant technology issues of printed circuit board (PCB) manufacture field.
