Description
Technical field
The present invention relates to the industries of chemical materials, relate in particular to a kind of high activity scaling powder.
Background technology
Scaling powder is typically with rosin mixture as main component, is the auxiliary material for ensureing welding process and being smoothed out
Material.Welding is the main processes in electronic assemblies, and scaling powder is the auxiliary material used when welding, and the main function of scaling powder is
It removes solder and by the oxide on weldering base material surface, metal surface is made to reach necessary cleannes.Surface when it prevents from welding
Re-oxidation reduces solder surface tension, improves welding performance.The quality of scaling powder performance, directly influences electronic product
Quality.
In recent decades, during electronic product produces soldering process, although generally using scaling powder solderability good, at
This is low, but postwelding residue is high.Its residue contains halide ion, and electrical insulation properties decline and short circuit etc. can gradually be caused to be asked
Topic, will solve the problems, such as this, it is necessary to clean to the rosin resin system film of flux residue in electronics printed board.So not only
Production cost can be increased, and the cleaning agent for cleaning rosin resin system welding assisted agent residuals is mainly fluorine chlorine compound.This chemical combination
Object is the loss substance of atmospheric ozone layer, the row for belonging to disabling and being eliminated.The technique for still having many companies to continue to use at present is to belong to
In the aforementioned technique cleaned again with cleaning agent using rosin resin system scaling powder scolding tin, less efficient and high expensive.This helps weldering
Agent has electronic component certain corrosivity, directly influences the quality of electronic product, when welding, at high temperature due to rosin
Volatilization, smell is very big, influences the health of operating personnel, after welding, lower rosin residue is left on printed wiring board, is also wanted
Cleaning, increases process.Once someone invented NCF no-clean scaling powders, but because containing camphor in its component, smell when welding
It is very big, the trace of fluxing agent is still had after welding, which belongs to inflammable thing again, and transport is highly difficult and of high cost, sale
Price so that this scaling powder cannot be by wide popularization and application.
