Description
Technical field
The present invention relates to a kind of technical field of solder(ing) paste, the more particularly to solder(ing) paste applied to signal distributor welding
And its preparation method.
Background technology
The surface mounting technology (Surface Mount Technology, abbreviation SMT) started in 1970s, be
Refer to the printed solder paste on printed circuit board pad, and Surface Mount Component be placed with the pad for being printed with solder(ing) paste,
According to specific reflux temperature curve（Generally total weld interval was at 5 ~ 6 minutes）Heater circuit plate, allows solder(ing) paste to melt, and it is closed
Solder joint is formed between component and printed circuit board and realize the metallurgical technology connected after golden composition cooled and solidified.
Solder(ing) paste is accompanied by a kind of novel welding material that SMT arises at the historic moment.Solder(ing) paste by solder powder, scaling powder and
The lotion of other additives mixeds.Solder(ing) paste has certain viscosity at normal temperatures, will can be bonded at both at the beginning of electronic component
Positioning is put, under welding temperature, with the volatilization of solvent and portions additive, will be by weldering component and printed circuit pad solder
Formed together permanently connected.
Maturation because of solder(ing) paste in SMT industries is used, production signal distributor enterprise for economization workman, reduce cost,
Improve efficiency, improve product quality so as to which solder(ing) paste to be applied to the welding of signal distributor, be different from SMT welding techniques, believe
The technique of number distributor is that solder(ing) paste is equably put to the shell that is coated onto and need to weld using point gum machine before welding, and coating is completed
Afterwards, the firing equipment by temperature higher than 500 DEG C is close to 1 ~ 2 centimetre of solder(ing) paste, by the effect of air heat transfer, general to require
Welding process was completed in 5 ~ 8 seconds.
Solder(ing) paste applied to signal distributor welding other conventional SMT that compare are compared with solder(ing) paste, during spot printing
Require to adapt to higher heating-up temperature in the bad phenomenon of layering, welding process it is required that occurring without under the impact of continuous atmospheric pressure,
The time of welding also requires that and completed in 5 ~ 8 seconds, because long weld interval can cause signal distributor to electroplate outside layer surface
The damage of sight and the circuit board function defect of shell parcel, while also requiring that the wettability of solder(ing) paste is strong during welding, because letter
The top layer of number distributor is electroless nickel layer, and nickel easily forms one layer of fine and close oxide-film in atmosphere, and this layer oxide film needs
Solder(ing) paste possesses very strong deoxidation ability.Require that residual is fewer and easily cleans after welding, to reach outside final products
See requirement attractive in appearance.
The requirement welded for above-mentioned signal distributor, if simply will SMT is applied to solder(ing) paste on the market at present
The welding of signal distributor, just occurs that the layering in above mentioned problem is bad, and dry joint and missing solder rate are high, and residual also compares many, and
And do not allow easy cleaning.Do not reach enterprise economization workman, save cost, improve the requirement of production effect and production quality.
Therefore, welding for signal distributor, it is necessary to specially adjusted to solder(ing) paste, patent
201010586234.0 ］ a kind of preparation method of spot coating type high-temperature solder(ing) paste is proposed, is welded for point coating type, when solving spot printing
The bad phenomenon being easily layered, while it is also ensured that being resistant to 340 DEG C of high temperature above reflow solderings when welding, residual is few after welding
Do not sinter, easily cleaning.But the alloy solder powder used in the patent is limited only to Sn5Pb92.5Ag2.5, solder powder
Sn5Pb92.5Ag2.5 is because leaded, and environmental pollution is serious, and weld interval when also not accounting for signal distributor welding
It is short, deoxidation ability strong requirement during welding.So tin cream that the patent is researched and developed and can guarantee that suitable for signal distributor
Welding needs.
The amount of solder(ing) paste used in signal distributor increasingly increases with the demand for development of manufacturing enterprise, but at present on the market simultaneously
Not exclusively for the tin cream product and related invention patent of signal distributor welding, so that specially exploitation is applied to signal distribution
The solder(ing) paste of device welding is excellent to be important.
In view of this, the present inventor proposes following technical proposals.
The content of the invention
The purpose of the present invention is to solve the above problems, providing a kind of solder(ing) paste for being used in particular for signal distributor welding
And preparation method thereof.The solder(ing) paste can occur without layering bad phenomenon when using point gum machine spot printing solder(ing) paste, can equably apply
Cloth removed solder powder completely in specified welding region in 5 ~ 8 seconds, and the oxide-film of electroplating surface layer prevents dry joint and missing solder
Bad generation, postwelding residual is few, is easily cleaned using environment-friendly cleaning agent.Reach the need with number distributor manufacturing enterprise
Ask.
What the purpose of the present invention was mainly realized by following technical scheme.
