Abstract
The utility model discloses a kind of surface mount sub-assembly, comprise a substrate, the element be welded on substrate, described surface mount sub-assembly also comprises a tool, and wherein, described tool comprises body and arranges containing hole in the body; Described element comprises matrix, is connected to the extension on the top of described matrix, and is connected to the pin of bottom of described matrix; On the substrate, described matrix has been installed with described body, and described extension is placed in described containing hole in described pin welding.By utilization of the present utility model, because tool is dexterous independent, there is the containing hole of matching element, be convenient to personnel's operation, improve operating efficiency, and increased substantially and prevent element from floating high effect.
Description
Technical field
The utility model relates to a kind of surface mount sub-assembly.
Background technology
At present in Electronics Factory's processing industry, during surface mount, in order to prevent the floating height of element in solder wave process, general employing sandbag or integral panels are carried out gland and are avoided element floating high.But these class methods can only use for the lower floating high element of General Requirements.Under element floats the very high situation of high request, sandbag is because of mobility, and element has indivedual inclination floating high.And integral panels gland, because element height is different and the dimensional tolerance of element own causes preventing floating high effect unstable.
Utility model content
The technical problems to be solved in the utility model easily produces floating high to overcome prior art surface mount, and element easily tilts, and the defect of the floating high effect instability of restriction, provides a kind of surface mount sub-assembly.
The utility model solves above-mentioned technical problem by following technical proposals:
A kind of surface mount sub-assembly, comprises a substrate, the element be welded on substrate, and its feature is, described surface mount sub-assembly also comprises a tool, wherein,
The containing hole that described tool comprises body and arranges in the body;
Described element comprises matrix, is connected to the extension on the top of described matrix, and is connected to the pin of bottom of described matrix;
On the substrate, described matrix has been installed with described body, and described extension is placed in described containing hole in described pin welding.
Preferably, the cross sectional shape of described containing hole is rectangle.
Preferably, the quantity of described pin is three.
Preferably, the height of described matrix is 3.86mm.
Preferably, the height of described extension is 3.86mm.
Preferably, the height of described body is 14mm.
Preferably, the quality of described tool is 60 grams.
Preferably, described substrate is printed circuit board.
In the utility model, above-mentioned optimum condition can combination in any on the basis meeting this area general knowledge, obtains each preferred embodiment of the present utility model.
Positive progressive effect of the present utility model is: by utilization of the present utility model, because tool is dexterous independent, has the containing hole hole of matching element, is convenient to personnel's operation, improves operating efficiency, and has increased substantially and prevent element from floating high effect.
