Description
Technical field
The utility model is related to a kind of circuit board, more particularly to a kind of double-deck half-open window cover oil wiring board.
Background technology
Printed circuit board is typically served to as each component provides necessary support in circuit in the electronic device, is easy to each
Individual component inserting, realizes that it is electrically connected.Widely used in an electronic.With the popularization of multilayer circuit board, silver
Slurry perforation and welding resistance consent technology are also more and more extensive to be used.But for double-layered circuit board, some need silver paste to pass through
Hole is used for the conductings of two copper foil layers, and some need welding resistance consent to be insulated, and is difficult during the actual grafting component of assist side
Distinguish.
The content of the invention
The purpose of this utility model is to provide one kind can visually distinguish silver paste hole filled and welding resistance consent, facilitates wiring board
Upper grafting and the double-deck half-open window cover oil wiring board of maintenance component.
In order to achieve the above object, the technical solution of the utility model is：A kind of double-deck half-open window cover oil wiring board, including
Substrate, the front of substrate and aspect are equipped with copper foil layer, and copper foil layer is provided with insulating barrier, the substrate be provided with it is silver paste hole filled and
Welding resistance consent, silver paste hole filled interior pouring fills silver paste, is poured in welding resistance consent and fills solder mask, is set on one of copper foil layer
There is the second through hole with silver paste hole filled coaxial first through hole and part overlaid welding resistance consent, another piece of copper foil layer is provided with and covers
The insulating lid in welding resistance consent aperture.
Second through hole of the copper foil layer and the equal diameters of welding resistance consent, and the second through hole axis and welding resistance consent
Hole wall is located on same upright position.
Silver paste perforation is coaxial with first through hole, and equal diameters.
The insulating barrier is insulating paint.
After said structure, the utility model when in use, due to one of copper foil layer be provided with it is silver paste hole filled
Coaxial first through hole and the second through hole of part overlaid welding resistance consent, therefore in actual use, operating personnel can be with
Visually observe, half hole for covering is welding resistance consent, and the hole of all-pass is silver paste hole filled, reduces the error that operator patches component.
And the insulating lid for covering welding resistance consent aperture is provided with another piece of copper foil layer, be conducive to reinforced insulation effect.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Specific embodiment
The utility model is described in further detail below in conjunction with the embodiment that accompanying drawing is given.
It is shown in Figure 1, a kind of double-deck half-open window cover oil wiring board, including substrate 1, the front of substrate 1 and aspect are all provided with
There is copper foil layer 2, copper foil layer 2 is provided with insulating barrier 3, and the substrate 1 is provided with silver paste hole filled 11 and welding resistance consent 12, silver paste hole filled
Pour in 11 and fill silver paste, poured in welding resistance consent 12 and fill solder mask, one of copper foil layer 2 be provided with it is silver paste hole filled
Second through hole 22 of 11 coaxial first through hole 21 and part overlaid welding resistance consent 12, another piece of copper foil layer 2 is provided with and covers resistance
The insulating lid 4 in weldering consent 12 aperture.
It is shown in Figure 1, in order to more conveniently distinguish welding resistance consent 12, the effect of half windowing is realized, the copper foil layer 2
The equal diameters of the second through hole 22 and welding resistance consent 12, and the axis of the second through hole 22 with the hole wall of welding resistance consent 12 positioned at same
On upright position.
Shown in Figure 1, in order to more conveniently distinguish silver paste hole filled 11, silver paste perforation 11 is same with first through hole 21
Axle, and equal diameters.
Shown in Figure 1, the insulating barrier 3 is insulating paint, or insulation dry film.
Shown in Figure 1, the utility model when in use, is poured in advance assist side corresponding silver paste hole filled 11 and fills silver
Poured in slurry, welding resistance consent 12 and fill solder mask.And because one of copper foil layer 2 is provided with coaxial with silver paste hole filled 11
Second through hole 22 of first through hole 21 and part overlaid welding resistance consent 12, therefore in actual use, operating personnel can be with
Visually observe, half hole for covering is welding resistance consent 12, and the hole of all-pass is silver paste hole filled 11, reduces the mistake that operator patches component
By mistake.And the insulating lid 4 for covering the aperture of welding resistance consent 12 is provided with another piece of copper foil layer 2, be conducive to reinforced insulation effect.
Above-described is only preferred embodiment of the present utility model, it is noted that for the ordinary skill of this area
For personnel, on the premise of the utility model creation design is not departed from, various modifications and improvements can be made, these all belong to
In protection domain of the present utility model.
