Technical field
The utility model is related to welding technique field, specially a kind of welding resistance precision improvement process unit.
Background technology
Welding resistance is between welded piece is pressed in two electrodes, and imposes electric current, using electric current flow through work piece interface and
The resistance fuel factor that adjacent domain generates is heated to fusing or mecystasis, is allowed to form a kind of method of metal combination,
It needs to use welding resistance during board production, still, circuit board resistance welding traditional handicraft is first punching (molding positioning at present
Hole) circuit, welding resistance, molding procedure afterwards, such technique is that will produce (circuit, welding resistance) stand-off error twice in production, two
Deviation is superimposed, and easily exceeds customer requirement tolerance.
Utility model content
The purpose of this utility model is to provide a kind of welding resistance precision improvement process units, to solve in above-mentioned background technology
The current circuit board resistance welding traditional handicraft proposed is first punching (molding location hole) circuit, welding resistance, molding procedure afterwards, such technique
To will produce (circuit, welding resistance) stand-off error twice, two deviation superpositions, easily asking beyond customer requirement tolerance in production
Topic.
To achieve the above object, the utility model provides the following technical solutions：A kind of welding resistance precision improvement process unit, packet
