Abstract
The invention discloses the engraving method of a kind of printed panel, include and utilize mapping software to draw predetermined pattern be prepared as film, then carve according to the moon or sun is carved and the part of pattern engraved or part beyond pattern is removed；Printed panel is carried out oil removing, decontamination, and surface carries out polishing, polishing；The pattern film of hollow out is covered on printing plate surface；Film coats etching paste, and by link plate, etching paste is uniformly scraped and be etched on the surface of printed panel；After having etched, film is removed；Printed panel is cleaned with circulating water.This engraving method greatly reduces processing step, thus improves production efficiency, and decreases the harm to operator of strong acid and highly basic, it also avoid the discharge of waste water.
Description
Technical field
The present invention relates to a kind of etching technique, the engraving method of a kind of printed panel.
Background technology
Traditional etching mainly needs parts to be protected, needs with ink or the photoresist silk-screen printing of acid and alkali-resistance
Etched be partially exposed at outside；Then etched for needs product is put into corrosion etching in strong acid, the most protected
Part is i.e. corroded, and the pattern that protected portion is divided just displays；Product places into after acid etching in alkali liquor and cleans
Remove ink or photoresist, so that it may obtain required figure.The shortcoming of this conventional etching process is complex process, to photoetching
The requirement that glue and surface process is the highest, additionally, due to use strong acid and highly basic to soak, the most in operation to people
Body has harm, and the waste water that technique produces also has the biggest harm to environment.
Summary of the invention
For the problem existing for above-mentioned prior art, it is an object of the invention to provide a kind of etching speed fast, hazardness
The engraving method of the simple printed panel of less and technique.
For reaching above-mentioned purpose, the technical solution adopted in the present invention is: the engraving method of a kind of printed panel, it is characterized in that
Comprise the following steps:
1) end processed: utilize mapping software draw predetermined pattern and be prepared as film, then carve according to the moon or sun is carved pattern
Part is engraved or part beyond pattern is removed；
2), at table: printed panel is carried out oil removing, decontamination, surface carries out polishing, polishing；
3) rubberizing: the pattern film of hollow out is covered on printing plate surface；
4) etching: coat etching paste on film, and by link plate, etching paste is uniformly scraped and lose on the surface of printed panel
Carve；
5) remove photoresist: after having etched, film is removed；
6) clean: clean printed panel with circulating water.
Preferably, described etching paste includes the compositions of following mass percent: ferric chloride 10%～15%, sulphuric acid
10%～20%, potassium dichromate 0.5%～1.0%, thickening agent 2%～8%, surplus is water.
Preferably, the thickness of described pattern film is 0.5 mm-1.5mm.
Preferably, described pattern film is pasted on the printed board by the glue that anti-permeability is strong.
Preferably, described etching belongs to the mode of dry etching, specifically the printed panel posting film is put into etching
In machine, etching machine surface to printed panel automatically is etched the coating of cream, uses repeatedly coating to be etched to required etch depth.
The invention have the benefit that the engraving method of the present invention is to use dry etching, i.e. eliminate to be etched
It is coated with protection ink or photoresist, the complicated technology then soaked with soda acid on device, greatly reduces processing step, thus carry
High production efficiency, and decrease the harm to operator of strong acid and highly basic, it also avoid the discharge of waste water.Meanwhile, this
Bright is to use etching machine to be etched operation, etches for full-automation, therefore further improves production efficiency, and more pacifies
Complete reliable.
Detailed description of the invention
Embodiment one:
This invention uses ferric chloride, the sulphuric acid of 10%, the potassium dichromate of 0.5% and the thickening agent of 5% of 15%, and surplus is water,
By the way of stirring mixes, prepare this etching paste, utilize this etching paste that printed panel is etched, its engraving method include with
Lower step:
1) end processed: utilizing mapping software draw predetermined pattern and be prepared as film, the thickness of this pattern film is 1mm, then
Carve according to the moon and the part of pattern is engraved；
2), at table: printed panel is carried out oil removing, decontamination, surface carries out polishing, polishing；
3) rubberizing: the pattern film of hollow out is covered on printing plate surface；
4) etching: putting in etching machine by the printed panel posting film, the surface of printed panel is etched by etching machine automatically
The coating of cream, uses repeatedly coating to be etched to required etch depth；
5) remove photoresist: after having etched, film is removed；
6) clean: clean printed panel with circulating water.
Embodiment two:
This invention uses ferric chloride, the sulphuric acid of 20%, the potassium dichromate of 0.8% and the thickening agent of 8% of 10%, and surplus is water,
By the way of stirring mixes, prepare this etching paste, utilize this etching paste that printed panel is etched, its engraving method include with
Lower step:
1) end processed: utilizing mapping software draw predetermined pattern and be prepared as film, the thickness of this pattern film is 0.5mm, so
Carve according to sun afterwards and the part beyond pattern is removed；
2), at table: printed panel is carried out oil removing, decontamination, surface carries out polishing, polishing；
3) rubberizing: the pattern film of hollow out is covered on printing plate surface；
4) etching: putting in etching machine by the printed panel posting film, the surface of printed panel is etched by etching machine automatically
The coating of cream, uses repeatedly coating to be etched to required etch depth；
5) remove photoresist: after having etched, film is removed；
6) clean: clean printed panel with circulating water.
Although the present invention is to be described with reference to specific embodiments, but this description is not meant to the present invention is constituted limit
System.With reference to description of the invention, other changes of the disclosed embodiments, for those skilled in the art be all it is anticipated that
, this change should belong in appended claims limited range.
