Description
Technical field
This utility model relates to pottery pcb board technical field, a kind of ceramic PCB doing resistance on substrate
Plate.
Background technology
Mainly by burying resistance (making multi-layer sheet, resistance material is embedded in inside PCB) or silk-screen in existing PCB technology
The method of carbon oil makes resistance on PCB；Burying resistance method processing difficulties, cost is the highest, it is impossible to batch production；Silk-screen carbon oil cost
Low, it is impossible to make the resistance that precision is higher.
Utility model content
The purpose of this utility model is to provide a kind of ceramic pcb board doing resistance on substrate, to solve the above-mentioned back of the body
The problem proposed in scape technology.
For achieving the above object, the following technical scheme of this utility model offer: a kind of pottery doing resistance on substrate
Pcb board, including ceramic bottom board and laser protection layer, described ceramic bottom board is provided with lower glaze protective layer, lower glaze protective layer sets
Be equipped with nesting on bronze layer, and bronze layer and resistance device be installed, bronze layer be provided above glazing protective layer, laser radiation
First laser protection layer and the second laser protection layer are installed on Ceng, and the second laser protection layer is positioned at the first laser protection layer
Right side.
Preferably, described first laser protection layer is inlayed transverse concave groove is installed.
Preferably, described second laser protection layer is inlayed longitudinal fluting is installed.
Preferably, described second laser protection layer is positioned at the first laser protection layer is demountable structure.
Compared with prior art, the beneficial effects of the utility model are: this kind of ceramic PCB doing resistance on substrate
Plate, by controlling conducting metal, fine wire controls resistance；By semiconductor lithography process, process is convenient to be controlled, can be easy
Realize producing in enormous quantities；Substrate uses ceramic wafer, buries the pcb board of resistance or silk-screen carbon oil more resistant to high pressure than tradition；Employing laser is adjusted
During resistance, it is provided with laser radiation plate, prevents the impaired of other positions, it is ensured that the safety of product.

Detailed description of the invention
Below in conjunction with the accompanying drawing in this utility model embodiment, the technical scheme in this utility model embodiment is carried out
Clearly and completely describe, it is clear that described embodiment is only a part of embodiment of this utility model rather than whole
Embodiment.Based on the embodiment in this utility model, those of ordinary skill in the art are not under making creative work premise
The every other embodiment obtained, broadly falls into the scope of this utility model protection.
Refer to Fig. 1-3, a kind of embodiment that this utility model provides: a kind of ceramic PCB doing resistance on substrate
Plate, including ceramic bottom board 4 and laser protection layer 5, ceramic bottom board 4 is provided with lower glaze protective layer 3, and lower glaze protective layer 3 is arranged
Have nesting on bronze layer 2, and bronze layer 2 that resistance device 6 is installed, bronze layer 2 be provided above glazing protective layer 1, laser
First laser protection layer 8 and the second laser protection layer 9 is installed on protective layer 5, and the second laser protection layer 9 is positioned at the first laser
The right side of protective layer 8, the first laser protection layer 8 is inlayed and is provided with transverse concave groove 7, the second laser protection layer 9 inlays installation
Having longitudinal fluting 10, the second laser protection layer 9 to be positioned at the first laser protection layer 8 is demountable structure.
Operation principle: during use, arranges lower glaze protective layer 3 on ceramic bottom board 4, arranges bronze on lower glaze protective layer 3
Layer 2, gold layering 2 arranges glazing protective layer 1, thus is processed, when using laser correction, put by laser protection layer 5
On this single unit system, sign transverse concave groove 7 or the position of longitudinal fluting 10, conveniently operate.
It is obvious to a person skilled in the art that this utility model is not limited to the details of above-mentioned one exemplary embodiment, and
And in the case of without departing substantially from spirit or essential attributes of the present utility model, it is possible to realize this practicality in other specific forms
Novel.Therefore, no matter from the point of view of which point, embodiment all should be regarded as exemplary, and be nonrestrictive, this practicality
Novel scope limits by claims rather than described above, it is intended that by the equivalency in claim that falls
All changes in implication and scope are included in this utility model.Any reference in claim should be considered as limit
Claim involved by system.
