Abstract
The utility model discloses a be used for heat sinkly and brazed structure of ring frame, including heat sink, heat sink middle part is provided with heat sink boss, the heat sink boss of heat sink surface surround is provided with the weld groove between heat sink boss and heat sink border, heat sink boss upper surface and side, heat sink upper surface all are provided with the chromium layer with the side, an object of the utility model is to provide a simple structure, low in production cost has avoided solder outflow weld groove, has improved welding quality, guarantees the qualification rate of product, reduces staff intensity of labour's be used for heat sinkly and brazed structure of ring frame.
Description
Technical field
The utility model belongs to integrated antenna package technical field, is specifically related to a kind of for the heat sink structure with the soldering of ring frame.
Background technology
Along with various High performance electronics fast development and generally apply, for having, the electronic shell demand of heat sink soldering is increasing, this just require that we must provide production efficiency higher, the heat sink housing that cost is lower, but the heat sink soldering of prior art still also exists some predicaments to be badly in need of solving:
1, the brazing mode of prior art cannot control the trickling of weld seam and solder accurately, causes production efficiency low, and welding quality is difficult to hold, and the qualification rate of product reduces, and adds welding cost;
2, welding process is difficult to hold, and operation requirements is high, requires to increase, increase the labour intensity of staff to the technical merit of staff.
Utility model content
The purpose of this utility model is to provide a kind of structure simple, and production cost is low, avoids solder and flows out weld groove, improve welding quality, ensure the qualification rate of product, reduce intensity of workers for the heat sink structure with the soldering of ring frame.
Technical solutions of the utility model are a kind of for the heat sink structure with the soldering of ring frame, comprise heat sink, described heat sink middle part is provided with heat sink boss, described heat sink surface is provided with weld groove around heat sink boss between heat sink boss and heat sink border, and described heat sink boss upper surface and side, heat sink upper surface and side are provided with layers of chrome.
Preferably, described weld groove sidewall and heat sink surface intersection corner angle sharp keen, the weld groove degree of depth is 0.1mm-0.3mm, does not have layers of chrome in weld groove.
Technical solutions of the utility model a kind of for the heat sink structure with the soldering of ring frame, described heat sink boss upper surface and side, heat sink upper surface and side are provided with layers of chrome, the wettability of solder in layers of chrome is poor, be difficult to diffusion, solder is not easily spread in heat sink surface, contact angle is larger, be beneficial to solder to trickle in heat sink surface, described heat sink surface is provided with weld groove around heat sink boss between heat sink boss and heat sink border, layers of chrome is not had in weld groove, the wetability of solder in weld groove is good, improve the diffusion of solder in weld groove, described weld groove sidewall and heat sink surface intersection corner angle sharp keen, when solder flows through, contact angle is larger, more avoid solder and flow out weld groove, improve welding quality, the labour intensity reducing staff simple to operate, reduce welding cost.
The utility model technology beneficial effect:
Technical solutions of the utility model a kind of for the heat sink structure with the soldering of ring frame, structure is simple, and production cost is low; The setting of weld groove and layers of chrome, makes solder trickle in weld groove, avoid solder flow out weld groove, weld groove sidewall and heat sink surface intersection corner angle sharp keen, further ensure the trickling of solder, improve welding quality, ensure that the qualification rate of product; Structural design makes operated by personnel simple, reduces the labour intensity of staff.

Embodiment
Understand technical solutions of the utility model for ease of those skilled in the art, now in conjunction with Figure of description, technical solutions of the utility model are described further.
As shown in Figure 1, Figure 2, Figure 3 and Figure 4, a kind of for the heat sink structure with the soldering of ring frame, comprise heat sink 1, heat sink boss 6 is provided with in the middle part of in the of described heat sink 1, described heat sink 1 surface is provided with weld groove 3 around heat sink boss 6 between heat sink boss 6 and heat sink 1 border, and described heat sink boss 6 upper surface and side, heat sink 1 upper surface and side are provided with layers of chrome 2.
Described weld groove 3 sidewall and heat sink 1 surperficial intersection corner angle sharp keen, weld groove 3 degree of depth is 0.1mm-0.3mm, does not have layers of chrome 2 in weld groove 3.
The structure of the heat sink and ring frame soldering of technical solutions of the utility model, in the fabrication process, first process heat sink 1, layers of chrome 2 is provided with again at heat sink boss 6 upper surface and side, heat sink 1 upper surface and side, finally between heat sink boss 6 and heat sink 1 border, mill out weld groove 3 around heat sink boss 6 on heat sink 1 surface, weld groove 3 degree of depth is 0.1mm-0.3mm, and processing and manufacturing is simple, reduces processing and manufacturing cost; Specifically in brazing process, solder 5 is placed in weld groove 3, ring frame 4 is placed between heat sink 1 side, one end and heat sink boss 6 side, solder 5 in weld groove 3 not easily flows out weld groove 3, improve the qualification rate of welding quality and product, staff easily holds operating process, and operating process is simple, improves working (machining) efficiency.
Technical solutions of the utility model are exemplarily described utility model by reference to the accompanying drawings above; obvious the utility model specific implementation is not subject to the restrictions described above; as long as have employed the various unsubstantialities that method of the present utility model is conceived and technical scheme is carried out to improve; or the design of utility model and technical scheme directly applied to other occasion, all within protection range of the present utility model without to improve.
