Abstract
The utility model discloses a special coated aluminum plate for printed circuit board drilling, which comprises an aluminum baseplate. A buffer layer is arranged on the upper surface of the aluminum baseplate, and the buffer layer is made of lubricating resin. The special coated aluminum plate has the advantages of simple structure, low cost and relatively loose storage and using environment; the accuracy of hole location is effectively improved; and the special coated aluminum plate has good lubricating and buffering effect, and excellent hole wall effect.
Description
Technical field
The utility model relates to a kind of printed substrate boring special-purpose coat aluminium sheet, belongs to printed circuit board drill hole and uses to get the subsidiary products field.
Background technology
Along with the development of PCB high-density interconnect technology (HDI), high density interconnect printed board and multi-layer sheet are more and more higher to the requirement of bore process.At present, in the auxiliary industry of PCB boring, the used upper cover plate of holing adopts thin aluminum sheet usually, but often occurs the phenomenon that some location are inaccurate and bore broken needle when boring, can't satisfy the boring requirement of high accuracy, small-bore.
The utility model content
It is a kind of simple in structure that the purpose of this utility model is to provide, and has good cushioning effect and can improve the printed substrate boring special-purpose coat aluminium sheet of position, hole precision.
For achieving the above object, the utility model has adopted following technical scheme:
A kind of printed substrate boring special-purpose coat aluminium sheet comprises aluminium base, and described aluminium base upper surface is provided with a cushion.
Preferably, described cushion is lubricating resin.
Compared with prior art, the beneficial effects of the utility model are:
1, simple in structure, cost is low, has looser storage and environment for use;
2, position, Effective Raise hole precision reduces the broken needle rate;
3, have good lubricated and cushioning effect, and the hole wall effect is splendid.
Description of drawings
Fig. 1 is the structural representation of printed substrate boring special-purpose coat aluminium sheet in the utility model one preferred embodiment.
The specific embodiment
Consult Fig. 1, this printed substrate boring special-purpose coat aluminium sheet comprises aluminium base 1, and described aluminium base 1 upper surface is provided with lubricating resin layer 2.
This embodiment determines the thickness of aluminium base and cushion according to the boring aperture size, and the best scope of application of present embodiment is consulted following table:
| Aperture (mm) | Aluminium base thickness (mm) | Lubricating resin thickness (mm) |
| Greater than 0.30 | 0.15 | 0.06 |
| 0.25～0.30 | 0.14 | 0.05 |
| 0.20～0.25 | 0.13 | 0.05 |
| 0.15 | 0.12 | 0.05 |
| 0.10 | 0.10 | 0.045 |
[0015]Present embodiment has cost advantage, and looser storage and environment for use are arranged, and obviously improves position, hole precision, and the hole wall effect is splendid.
Below only be concrete exemplary applications of the present utility model, protection domain of the present utility model is not constituted any limitation.All employing equivalents or equivalence are replaced and the technical scheme of formation, all drop within the utility model rights protection scope.
Claims (2)
