Abstract
The invention relates to a copperization tank applied to the horizontal copperization process of a flexible printed circuit board. The copperization tank comprises a main tank body, a sub tank body and a plurality of rollers, reaction liquid medicine is contained in and flows in the main tank body and the sub tank body, the rollers are divided into two layers and distributed in the main tank body and the sub tank body, water jet cutters are arranged between the rollers at the communication position of the main tank body and the sub tank body, the lower-layer rollers located close to the bottom of the main tank body and the bottom of the sub tank body are tightly distributed, the distribution density of the upper-layer rollers arranged above the lower-layer rollers is smaller than that of the lower-layer rollers, and the rollers located at the water jet cutters are sheet rollers provided with flowing grooves where the reaction liquid medicine can flow. By means of the copperization tank, the liquidity of the reaction liquid medicine in the copperization tank can be enhanced, occurrence of dead corners in circulation of the reaction liquid medicine is lowered, forming and gathering of copper particles are avoided, and abnormal copperization in reactions is avoided.
Description
Technical field
The present invention relates to a kind of change copper groove used in flexible printed wiring board complanation copper wiring.
Background technology
Routine two-sided/multi-layer soft printed substrate production process in, between making every layer, complete conducting, need by PTH(chemical copper) complete the conductor in non-conductor region in hole.
In horizontal PTH operation process, reaction is carried out in the change copper groove be made up of major trough and secondary groove, because change copper groove liquid medicine is self-catalysis formula redox reaction, under its stability needs the stability of liquid medicine self and external environment to stabilize double action, liquid medicine id reaction can be avoided to separate out copper particle and the large area knot copper that causes is abnormal.And the roller arranged in the cell body of existingization copper groove is solid roller and concentrated type arrangement, as shown in Figures 1 and 2, it can cause, and liquid medicine circulation is not good there will be knot copper.
Summary of the invention
The object of this invention is to provide and a kind ofly improve reaction liquid medicine circulation and avoid tying the change copper groove of copper exception.
For achieving the above object, the technical solution used in the present invention is:
A kind of change copper groove be applied in flexible printed wiring board complanation copper wiring, comprise major trough, secondary groove, several rollers, splendid attire in described major trough and described secondary groove circulation reaction liquid medicine, described roller divides and is two-layerly arranged in described major trough and described secondary groove, described major trough be connected with described secondary groove place roller between be provided with water cutter, in two-layer described roller, lower floor's roller of the bottom of close described major trough and described secondary groove is closely arranged, the arrangement density being arranged at the upper strata roller above described lower floor's roller is less than the arrangement density of described lower floor's roller, the described roller at described water cutter place is the sheet roller of the circulation groove it offering the reaction liquid medicine that can circulate described.
Preferably, the two ends of described roller are installed between two relative sidewalls of secondary groove between two relative sidewalls of described major trough or described by lining, described lining comprise be arranged at described major trough sidewall on or described secondary groove sidewall on body, the groove be opened on described body, the end of described roller insert described in groove in and relative with the bottom land of described groove.
Preferably, the interval in described upper strata roller between two adjacent rollers is identical with the wheel footpath of a roller.
Preferably, the lower floor's roller be arranged in the middle part of secondary groove in the middle part of described major trough or described is also provided with the sheet roller of the circulation groove it offering the reaction liquid medicine that can circulate described.
Because technique scheme is used, the present invention compared with prior art has following advantages: of the present inventionization copper groove can strengthen the circulation of wherein reacting liquid medicine, reduce reaction liquid medicine circulation time and occur position, dead angle, thus prevent formation and the gathering of copper particle, avoid in reaction, occurring that knot copper is abnormal.

Embodiment
Below in conjunction with embodiment shown in the drawings, the invention will be further described.
Embodiment one: shown in accompanying drawing 3 and accompanying drawing 4.A kind of change copper groove be applied in flexible printed wiring board complanation copper wiring, comprise splendid attire and the major trough 1 of circulation reaction liquid medicine and secondary groove 2, the roller 3 that some axis parallel is provided with in major trough 1 and secondary groove 2,3 points, these rollers are two-layer to be arranged in major trough 1 and secondary groove 2, be respectively bottom the major trough 1 and lower floor's roller bottom secondary groove 2 and the upper strata roller that is positioned at above lower floor's roller, and major trough 1 to be connected with secondary groove 2 place roller 3 between be provided with water cutter 4.When carrying out complanation copper wiring, roller 3 rolls and impels the reaction liquid medicine in major trough 1 and secondary groove 2 to circulate.In order to improve the circulation of liquid medicine in this process, take following scheme: in two-layer roller 3, lower floor's roller is closely arranged successively, the arrangement density of upper strata roller is then less than the arrangement density of lower floor's roller, such as, to make in the roller of upper strata the interval between two adjacent rollers 3 identical with the wheel footpath of a roller, namely adopt batch (-type) arrangement mode.Meanwhile, the roller at water cutter 4 place adopts the sheet roller 5 of the circulation groove it offering the reaction liquid medicine that can circulate, this sheet roller 5 can be that multiple roller monomer serial connection forms, and forms circulation groove between adjacent roller monomer.Can also also be provided with being arranged in the lower floor's roller in the middle part of major trough 1 or in the middle part of secondary groove 2 the sheet roller 5 it offering the circulation groove reacting liquid medicine that can circulate, all the other each rollers 3 still adopt conventional solid roller.Like this, when reacting, each roller 3 rotates, relative to existingization copper groove, the circulation of reaction liquid medicine between each roller 3, exchange rate and frequency can be strengthened, and even the switching performance of the whole groove liquid medicine of the liquid medicine between upper strata roller and lower floor's roller is strengthened, thus avoids the copper particle caused because mobility is poor to separate out.
The two ends of roller 3 to be installed between two relative sidewalls of major trough 1 by lining 6 or between two of secondary groove 2 relative sidewalls, lining 6 comprise be arranged at major trough 1 sidewall on or secondary groove 2 sidewall on body.Existing lining 6 adopts the mode offering through hole on body, the end of roller 3 is worn in through-holes, but this through hole changes the inside and outside of copper groove owing to being communicated with, liquid medicine is made to produce the extra consumption outside reacting, so improve, the body of lining 6 is offered not through groove 7, as shown in Figure 5, the end of roller 3 to be inserted in groove 7 and relative with the bottom land of groove 7, thus liquid medicine consumption can be reduced, the liquid level in guaranteeization copper groove.
Above-described embodiment, only for technical conceive of the present invention and feature are described, its object is to person skilled in the art can be understood content of the present invention and implement according to this, can not limit the scope of the invention with this.All equivalences done according to Spirit Essence of the present invention change or modify, and all should be encompassed within protection scope of the present invention.
