First welding unit, is electrically connected with described power module;
Second welding unit, is electrically connected with described electricity consumption module;
Spacer region, is arranged between described first welding unit and described second welding unit, in order to described first welding unit and described second welding unit to be isolated.
Preferably, described spacer region is positioned at the centre position of described pad horizontal direction.
Preferably, the curved bar shaped in described spacer region.
Preferably, described spacer region becomes " V " font.
Preferably, described spacer region is arranged along any diagonal of described pad.
Preferably, in described first welding unit, and/or described second welding unit is provided with one deck solubilized conducting metal.
Preferably, the electric current that described in the thickness matching of described solubilized conducting metal, the first welding unit and described second welding unit carry.

Compared with prior art, the utility model has the advantages that: by arranging spacer region on pad, the convenient power module to model machine or complete machine are debugged separately, and debugging step is simple, and the structure of pad is simple, and production efficiency is high, and production cost is lower.
Accompanying drawing explanation
Fig. 1 is the structural representation of a kind of embodiment of the present utility model.
Fig. 2 is the structural representation of another kind of embodiment of the present utility model.
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail, but not as restriction of the present utility model.
As shown in Figure 1, a kind of pad, is applied to being provided with on the device of power module and electricity consumption module, wherein: pad is provided with: the first welding unit 1, is electrically connected with power module; Second welding unit 2, is electrically connected with electricity consumption module; Further, in the first welding unit 1, and/or the second welding unit 2 is provided with one deck solubilized conducting metal, further, solubilized conducting metal can be solder(ing) paste.Spacer region, is arranged between the first welding unit and the second welding unit, in order to the first welding unit and the second welding unit to be isolated.
Operation principle of the present utility model is:
In development, when the power module of model machine is debugged, because spacer region 3 isolates the connection of the first welding unit 1 and the second welding unit 2, the signal that power module exports cannot transfer to power unit, and then independent test can be carried out to power module, after to be debugged, by carrying out manually going up tin process to the first welding unit 1 and the second welding unit 2, solder(ing) paste on first welding unit 1 is connected with the soldering paste on the second welding unit 2, and then the first welding unit 1 is communicated with the second welding unit 2, namely power module is communicated with power unit, conveniently whole model machine is debugged.
In process of production, windowed process in spacer region 3, in solder(ing) paste high-temperature heating process on solder(ing) paste on first welding unit 1 and the second welding unit 2, solder(ing) paste is under liquid condition, by surface tension of liquid, the first scolding tin unit is connected with the second scolding tin unit, realizes the connection of the first welding unit 1 and the second welding unit 2.
Adopt above-mentioned pad, structure is simple, and the convenient power module to model machine or complete machine are debugged separately, and debugging step is simple, and production efficiency is high, and production cost is lower.
As shown in Figure 1 or 2, as further preferably implementation method, spacer region 3 is positioned at the centre position of pad horizontal direction.Spacer region 3 can curved bar shaped.Spacer region 3 can be " one " font, " V " font or any diagonal setting along pad, and adopt the spacer region 3 of " one " font or " V " font to design, structure is simple, and conveniently realizes producing.
As further preferably implementation method, the electric current that thickness matching first welding unit of solubilized conducting metal and the second welding unit carry.Solubilized conducting metal is in the first welding unit, and/or on the second welding unit, solubilized conducting metal can become ladder section, is namely greater than the thickness of the solubilized conducting metal away from spacer region 3 near the thickness of the solubilized conducting metal of spacer region 3.Make the solder(ing) paste thickness after merging can carry the electric current with the first welding unit 1/ second welding unit 2.
As further preferably implementation method, the width range of spacer region 3 is 5 ~ 15 mils.Adopt the spacer region 3 of 5 ~ 15 mil width, can ensure in process of production, the surface tension of liquid of solder(ing) paste can by the solder(ing) paste short circuit of the solder(ing) paste of the first welding unit 1 and the second welding unit 2.Further, the width range of spacer region 3 is 10 mils.The tension force of solder(ing) paste under liquid condition being conducive to the solder(ing) paste and the second welding unit 2 realizing the first welding unit 1 further merges.
As further preferably implementation method, spacer region 3 is for windowing welding resistance district.When needs short circuit first welding unit 1 and the second welding unit 2, windowed process in spacer region 3, facilitate the short circuit of the first welding unit 1 and the second welding unit 2.Further, spacer region 3 also can be insulation layer or is filled with the spacer region of isolation material, can realize the interval of the first welding unit 1 and the second welding unit 2.
These are only the utility model preferred embodiment; not thereby execution mode of the present utility model and protection range is limited; to those skilled in the art; should recognize and all should be included in the scheme that equivalent replacement done by all utilization the utility model specifications and diagramatic content and apparent change obtain in protection range of the present utility model.
