Description
Technical field
The present invention relates to soldering tech field, more particularly to a kind of soldering processes.
Background technology
Soldering is to make solder using metal material more low-melting than mother metal, and weldment and solder heat are melted to higher than solder
Point, less than mother metal fusion temperature, mother metal is soaked using liquid solder, fill play movement and realize connection with the counterdiffusion of mother metal phase
The method of weldment.Brazing deformation is small, joint smooth and beautiful appearance, is suitable for accurate welding, complexity and the component being made up of different materials,
Such as honeycomb panel, turbine blade, hard alloy cutter and printed circuit board (PCB).But traditional soldering processes are universal at present
Cost height, complex process, the problem of product yield after welding is relatively low be present.
The content of the invention
It is an object of the invention to solve the problems, such as that background section above is mentioned by a kind of soldering processes.
To use following technical scheme up to this purpose, the present invention：
A kind of soldering processes, it comprises the following steps：
S101, greasy dirt, the oxide for removing welding workpiece surface：Greasy dirt is removed with organic solvent, using file, metal
Brush, sand paper either type remove the oxide of the workpiece surface；
S102, in the workpiece surface metal lining；
S103, soldering positioned using alignment pin：
Stop-off gent is coated on the piece surface of adjacent joint before S104, soldering；
S105, the workpiece after soldering soaked 3 minutes in 70-75 DEG C of hot water, the residue cleaned on brazed seam.
Especially, removing greasy dirt with organic solvent in the step S101 also includes：Workpiece is immersed into 50-73 DEG C severe
Degreasing in property sodium solution.
Especially, the step S102 is specifically included：Using galvanoplastic in the workpiece surface metal lining.
Especially, the step S105 also includes：Hot water injection is flowed with 70-75 DEG C 5 minutes；With 70-75 DEG C of flowing heat
Water rinses 3 minutes, is then placed in oxalic acid solution and soaks；Cold water flush is used after taking-up again.
Soldering processes proposed by the present invention are simple to operate, and welding quality is high, and product zero rate is guaranteed, and cost is low.
Brief description of the drawings
Fig. 1 is soldering processes flow chart provided in an embodiment of the present invention.
Embodiment
For the ease of understanding the present invention, the present invention is described more fully below with reference to relevant drawings.In accompanying drawing

Degreasing in the soda lye of 50-73 DEG C of part immersion.
S102, in the workpiece surface metal lining.In the present embodiment using galvanoplastic in the workpiece surface plating
Metal.
S103, soldering positioned using alignment pin.
Stop-off gent is coated on the piece surface of adjacent joint before S104, soldering.
S105, the workpiece after soldering soaked 3 minutes in 70-75 DEG C of hot water, the residue cleaned on brazed seam.
Hot water injection is flowed with 70-75 DEG C 5 minutes；Hot water injection is flowed with 70-75 DEG C 3 minutes, and it is molten to be then placed on oxalic acid
Soaked in liquid；Cold water flush is used after taking-up again.
Technical scheme is simple to operate, and welding quality is high, and product zero rate is guaranteed, and cost is low.
Pay attention to, above are only presently preferred embodiments of the present invention and institute's application technology principle.It will be appreciated by those skilled in the art that
The invention is not restricted to specific embodiment described here, can carry out for a person skilled in the art various obvious changes,
Readjust and substitute without departing from protection scope of the present invention.Therefore, although being carried out by above example to the present invention
