Description
Technical field
The present invention relates to board production technical field.
Background technology
Along with the multi-functional development of electronic product, PCB designs insert hole, crimping hole etc. and also gets more and more, this type of
Hole is easy to be strayed into ink in the operation of printing solder mask and causes plank quality not pass a test, and this is accomplished by using catch point net generation
Ink printing is carried out for white net.Catch point net is higher than the cost of manufacture of common white net, but can effectively reduce ink hand-hole；For height
For laminate and the high pcb board of quality requirements, production have to be used catch point net.It addition, for large-sized wiring board,
Also needing to use corresponding large-sized catch point net, this its para-position efficiency of large-sized catch point net and accuracy also can decline therewith,
In production, the bad phenomenon such as ink hand-hole highlights, cause returning wash, do over again, scrap cost is increased sharply.It is bad in order to improve ink hand-hole,
Promoting catch point net particularly large scale catch point net para-position efficiency, improve catch point net press quality, catch point net manufacture method is to closing weight
Want.
Summary of the invention
For the problems referred to above, the present invention provides a kind of large scale catch point net manufacture method, and this comprises the following steps: (1) adopts
Defat is carried out with the new net of remover solution soaking；(2) coating photoresists；(3) catch point graph exposure；(4) develop and dry.
Concrete, need after the defat of step 1) www.chinanews.com to dry.
Concrete, step 2) in need to dry after coating photoresists.
Preferably, remover solution soaking 5-10min using 0.2% concentration in step 1) carries out defat.
Preferably, step 2) in photosensitive slurry applied thickness be 12-15um.
Preferably, step 2) in 45 ° of new net is tiltedly put, scraper becomes 60 ° with wire side, bottom-up continuous blade coating, positive and negative
Coating.
Preferably, in step 3), the medicine face para-position of film egative film is attached on half tone, and film egative film is placed on exposure down
On board, film pattern edge distance screen frame marginal dimension >=100mm.
Preferably, in step 3), exposure parameter sets: evacuation-680 to-720mmHg, time of exposure 110 ± 15 seconds,
Use 21 grades of exposure guide rules.
Preferably, the half tone after exposure is stood 5-10 minute by step 4), then infiltrates afterflush with clear water, until unexposed
Partial flushing totally realizes development.Preferably, step 4) is dried temperature and controls as 40-45 DEG C, drying time 10-15 minute.
Compared with prior art, catch point net manufacture method of the present invention has the beneficial effects that:
1, in the case of equipment is constant, by the specifications parameter of supplied materials half tone of keeping under strict control, optimize catch point net and make parameter, Perceived control
Light thickness and graph exposure parameter, to reach effectively to control catch point net dimensional stability, graphical analysis effect clearly；Particularly
Making to large scale catch point net, the present invention disclosure satisfy that 24*28 inch and the making of above big plate catch point net, owing to improving
Catch point net precision, thus substantially increase frame net para-position printing efficiency, when reducing printing ink of circuit board printing, ink hand-hole is not
Good phenomenon；
2, use the method for the invention to make catch point net, experiments verify that, hoisting frame net para-position printing efficiency about 8%, reduce oil
The rate of washing about 2% of doing over again of ink hand-hole, reduces ink hand-hole scrappage about 0.25%..
Detailed description of the invention
The present invention is done the most in detail below in conjunction with specific embodiment for the ease of it will be appreciated by those skilled in the art that
Describe.
Described catch point net manufacture method, comprises the following steps:
(1) the new net of remover solution soaking is used to carry out defat；I.e. use remover solution soaking 5-10min of 0.2% concentration,
New net is carried out defat.After new net defat, needing to dry, general baking temperature controls, for 40-45 DEG C, to toast 10-
15min.So, grenadine sufficiently dry, without steam.
(2) coating photoresists；Positive and negative is required for being coated, photosensitive slurry applied thickness 12-15um.During coating, will be new
45 ° of net is tiltedly put, and scraper becomes 60 ° with wire side, and bottom-up continuous blade coating.After new net applies photosensitive slurry, formed at new net surface
One layer of light-sensitive surface, needs again to dry, and dries light-sensitive surface.Baking temperature is preferably controlled to 40-45 DEG C, drying time 20-
25min.Repeatable above-mentioned steps 2-3 time, it is optimal for making final photographic film thickness reach 36-45um.
(3) catch point graph exposure；Being attached on half tone by film egative film medicine face, film egative film is placed on exposure machine down
On platform, film pattern edge distance screen frame marginal dimension >=100mm, exposure parameter sets: evacuation so that air pressure is-680
To-720mmHg, time of exposure, between 110 ± 15 seconds, uses 21 grades of exposure guide rules, i.e. exposure lattice 3-4 lattice.
(4) develop and dry；Half tone after exposure is stood 5-10 minute, then infiltrates afterflush with clear water, until not exposing
Light partial flushing totally realizes development.After development, needing to dry half tone, baking temperature controls as 40-45 DEG C, during drying
Between 10-15min.
In order to preferably make catch point net, also needing the new net to making catch point net to select, preferably mesh number is the oblique of 36T
Draw in the net；It is 22.5 ± 7.5 ° that new net draws in the net angle, and the tension force after drawing in the net controls at 31 ± 3N/cm2；Measuring some off-network frame edge is
5-10cm.So, by 5 methods measured, uniformity can be obtained and reach more than 90%.
After above-mentioned steps terminates, so that it may make catch point net.After catch point net prepares, can carry out catch point net examining net, it is preferred that
Catch point net uses film egative film to check, it is preferred that the catch point net that also can choose additive method prepared carries out check and inspection.
To sum up, the present invention is in the case of equipment is constant, by the specifications parameter of supplied materials half tone of keeping under strict control, optimizes catch point net
Make parameter, control photosensitive thickness and graph exposure parameter, clear to reach effectively to control catch point net dimensional stability, graphical analysis
Clear effect, thus carry overhead net para-position printing efficiency, reduce ink hand-hole bad.
Use the method for the invention make catch point net, experiments verify that, can hoisting frame net para-position printing efficiency about 8%, subtract
The rate of washing about 2% of doing over again of few ink hand-hole, reduces ink hand-hole scrappage about 0.25%.
Being more than the specific implementation of the present invention, it describes more concrete and detailed, but can not therefore be interpreted as
Restriction to the scope of the claims of the present invention.It should be pointed out that, for the person of ordinary skill of the art, without departing from this
On the premise of bright design, it is also possible to make some deformation and improvement, these obvious alternative forms belong to the present invention's
Protection domain.
