Abstract
The invention discloses a manufacturing process of electrically conductive printing ink for a printed board. The process comprises steps as follows: 1) before screen printing, fully stirring a carbon paste printing material and fully mixing components; 2) performing cleaning treatment on the surface of a base board by using three-dimensional high-pressure cleaning; 3) performing screen printing, standing for 10 min, and performing pre-drying; 4) curing a screen-printed lead and controlling the melting temperature within 110 DEG C. According to the manufacturing process of the electrically conductive printing ink for the printed board, the lead edge is well coated, and problems that pinholes and skip printing exist on a coating are solved.
Description
Technical field
The present invention relates to a kind of manufacturing process manufacturing electrically conductive ink in printed board process.
Background technology
Electrically conductive ink is a kind of functional print material, be different from the operational characteristic of other ink, its maximum difference is containing very a high proportion of metal paste in component, play electric action, slurry in printed board has carbon to starch, copper slurry and silver slurry, electrically conductive ink is mainly used in the button of single double-clad board, bridging conductor, perforation, the repairing of breach broken string and the making of flexible printed board wire pattern, copper conductor is replaced with electrically conductive ink, wire mark forms circuit at insulator surface, during existing conductive ink process solidification, temperature of fusion controls at 120-150 DEG C, time is 30-40 minute, easily at wire edge dew copper, rete there is the problem such as pin hole and skip printing.
Summary of the invention
Goal of the invention: the invention solves the problems referred to above, provides a kind of wire edge covering property good, and solves the manufacturing process of printed board electrically conductive ink rete having pin hole and skip printing problem.
Technical scheme: the manufacturing process of a kind of printed board electrically conductive ink of the present invention, comprises the following steps:
(1) before wire mark, carbon slurry print material is fully stirred, fully mixes between component;
(2) three-dimensional high pressure cleaning is utilized to carry out clean to substrate surface;
(3) wire mark, leaves standstill 10 minutes, carries out preliminary drying;
(4) solidified by the wire of wire mark, temperature of fusion controls at 110 DEG C.
Particularly, in described step (4), set time is 20 minutes.
Particularly, in described step (1), carbon slurry main component is black carbon black.
Beneficial effect: the present invention compared with prior art, its advantage is to shorten set time, reduce solidification value, coordinate three-dimensional high pressure cleaning, effectively can remove the impurity of metallic surface, after hardening, make the wire edge covering property of wire mark good, solve problem rete having pin hole and skip printing, flex resistance is good.
Embodiment
Below in conjunction with embodiment, illustrate the present invention further.
A manufacturing process for printed board electrically conductive ink, comprises the following steps:
(1) before wire mark, carbon slurry print material is fully stirred, fully mixes between component;
(2) three-dimensional high pressure cleaning is utilized to carry out clean to substrate surface;
(3) wire mark, leaves standstill 10 minutes, carries out preliminary drying;
(4) solidified by the wire of wire mark, temperature of fusion controls at 110 DEG C.
First, before wire mark, fully stirred by carbon slurry print material, fully mix between component, to guarantee that component is even, the main component of carbon slurry is black carbon black, easily produces precipitation during storage;
Secondly carry out clean to substrate surface, wipe oil, guarantee that surface clean is without dust, utilize omnidirectional three-dimensional crossing net trellis to gather the high-pressure cleaning system of cleaning, flushing pressure is large, and the top hole pressure of high-pressure pump, up to 60-80MPa, cleans up thoroughly.
Start wire mark, add less or do not add thinner as far as possible during wire mark, leave standstill 10 minutes, carry out preliminary drying;
Finally solidified by the wire of wire mark, make temperature keep 110-120 DEG C during solidification, set time is 20 minutes as far as possible.
Present invention reduces set time, reduce solidification value, coordinate three-dimensional high pressure cleaning, effectively can remove the impurity of metallic surface, after hardening, make the wire edge covering property of wire mark good, solve problem rete having pin hole and skip printing, flex resistance is good.
