Description
Technical field
The present invention relates to printed circuit board manufacture technology field, the silk-screen half tone particularly relating to a kind of printed circuit board makes
Method.
Background technology
During printed circuit board welding resistance silk-screen consent, need to use silk-screen half tone as medium to carry out ink print
Dataller makees, and the aluminium flake that silk-screen half tone mostly uses thickness to be about 0.15mm, first pass through machine drilling and carry out and figure phase
The Drilling operation joined, is formed after then carrying out block, and the Making programme of half tone is more complicated.Due to printed circuit board hole count relatively
Many, machine dimensions drill is time-consuming relatively big in process of production, and production efficiency is relatively low, and the equipment that machine dimensions drill is high production value, causes
Cost payout is bigger.
Therefore, it is necessary to provide the silk-screen manufacturing method of screen of a kind of production efficiency height and low cost to solve above-mentioned asking
Topic.
Summary of the invention
The technical issues that need to address of the present invention are to provide a kind of production efficiency height and the silk-screen half tone making side of low cost
Method.
For solving above-mentioned technical problem, the present invention provides the manufacture method of a kind of silk-screen half tone, and it comprises the steps:
S1: apply an ink layer on aluminium flake to be produced；
S2: use the half tone film that described ink layer is carried out figure transfer, the described half tone film is covered at described ink
On Ceng, being exposed, the light through described half tone film transparent part can react with described ink layer, makes described oil
Layer of ink is hardening, forms anti-weakly alkaline hardening ink figure layer；
S3: aluminium flake develops, the described half tone film of taking away, is developed by aluminium flake bubble in the middle of weakly alkaline developing agent, institute
State the described ink layer on aluminium flake to react with developing agent and come off, thus retain described hardening ink figure layer；
S4: aluminium flake etches, and is etched at aluminum flake surface with etchant, the institute that described hardening ink figure layer will not had to cover
State aluminium flake eating thrown, thus obtain the figure hole needed；
S5: take off film, washes the etchant on described aluminium flake, is immersed in by described aluminium flake and takes off a period of time in membrane, goes
Fall described hardening ink figure layer, obtain silk-screen half tone.
2, the manufacture method of silk-screen half tone according to claim 1, it is characterised in that in step S1, described ink
The applied thickness of layer is at more than 12um.
In step S1, before applying described ink layer, described aluminium flake is carried out.
In step S2, the described half tone film need to be made in advance according to the figure of silk-screen half tone to be produced and aperture, described
The half tone film is negativity egative film, and it includes shading region and transparent area, and the size of described shading region is than described silk-screen half tone to be produced
The big 0.1mm in aperture.
In step S3, described developing agent uses sodium carbonate.
Compared with prior art, during the silk-screen manufacturing method of screen of the present invention uses printed circuit board figure transfer flow
Etch process, carries out figure transfer and makes, etch out by the position, figure hole required for silk-screen half tone, obtain quality and close aluminium flake
The silk-screen half tone of lattice, has saved production cost greatly, simplifies the Making programme of silk-screen half tone, improves production efficiency.
Accompanying drawing explanation
Fig. 1 is the schematic flow sheet of the silk-screen manufacturing method of screen of the present invention.
Fig. 2 is the structural representation of the half tone film used in the silk-screen manufacturing method of screen in Fig. 1.
Detailed description of the invention
Below in conjunction with drawings and embodiments, the invention will be further described.
As it is shown in figure 1, the silk-screen manufacturing method of screen of the present invention comprises the steps:
Step S1: aluminium flake ink applies, and aluminium flake 11 surface to be produced is carried out Chemical cleaning, and carries out wet film on its surface
Painting applies an ink layer 12, and the applied thickness of described ink layer 12 is at more than 12um；
Step S2: use the half tone film to carry out figure transfer, after product baking step S1 obtained, by the half tone film 10
Covering on described ink layer 12, be exposed with ultraviolet, the light through half tone film transparent part can be with described oil
Ink in layer of ink 12 reacts, and makes described ink layer 12 hardening, forms anti-weakly alkaline hardening ink figure layer 121；And institute
The described ink layer 12 stating the covering of the half tone film 10 lighttight black part then will not react；
Wherein, the described half tone film 10 need to be made in advance according to the figure of silk-screen half tone to be produced and aperture, such as Fig. 2 institute
Showing, the described half tone film 10 is negativity egative film, and it includes shading region 101 and transparent area 102, with described on the described half tone film 10
Region corresponding to region that silk-screen half tone to be produced needs perforate is shading region 101, and other region is transparent area 102, shading region
The size of 101 is than the big 0.1mm in aperture of described silk-screen half tone to be produced；
Step S3: aluminium flake develops, aluminium flake 11 is steeped in the middle of weakly alkaline developing agent, institute by the described half tone film 10 of taking away
Stating developing agent can use sodium carbonate, the described ink layer 12 of the not alkali resistance on described aluminium flake 11 will react with sodium carbonate
Come off, thus retain described hardening ink figure layer 121；
Step S4: aluminium flake etches, and is etched at aluminum flake surface with etchant, in etching process, needs aluminium flake directly
Exposed region etches away, and will not have described aluminium flake 11 eating thrown that described hardening ink figure layer 121 covers, thus obtains and machinery
The hole that drilling effect is identical；
Step S5: take off film, washes the etchant on described aluminium flake 11, is immersed in by described aluminium flake 11 and takes off in membrane one section
Time, described hardening ink figure layer 121 can be removed.
Through above-mentioned steps, i.e. can get the silk-screen half tone of certified products matter.
Compared with prior art, during the silk-screen manufacturing method of screen of the present invention uses printed circuit board figure transfer flow
Etch process, carries out figure transfer and makes, etch out by the position, figure hole required for silk-screen half tone, obtain quality and close aluminium flake
The silk-screen half tone of lattice, has saved production cost greatly, simplifies the Making programme of silk-screen half tone, improves production efficiency.
The foregoing is only embodiments of the invention, not thereby limit the scope of the claims of the present invention, every utilize this
Equivalent structure or equivalence flow process that bright description and accompanying drawing content are made convert, or are directly or indirectly used in other relevant skill
Art field, is the most in like manner included in the scope of patent protection of the present invention.
