Disclosed is a flux composition for a lead-free solder, which is characterized by containing components derived from rosins.
Also disclosed is a method for cleaning a solder flux.
Epoxy flux surrounds the individual solder masses.
Because of this, the formed solder thus obtained contains a flux remaining in a slight amount.
Also disclosed is a lead-free solder composition which contains the flux composition and a lead-free solder alloy.
The ball solder and the solder alloy used for the cream solder have a eutectic composition.
A component with inadequate flux for reliable soldering can be rejected.
Solder (28) is secured within the cavity, and flux (30) is secured within the cavity (20) in contact with the solder (28).
Also, a diverging guide wall is provided at an outflow opening of the casing to stabilize the flow of solder.
A composition, a method, and a system for a solder flux are disclosed herein.
Disclosed is a flux composition for a lead-free solder, which is characterized by containing components derived from rosins.
An optoelectronic device is disposed within the enclosed volume and a wick stop for preventing solder flow is provided.
An epoxy material different in composition from the epoxy flux surrounds the epoxy flux on the individual solder masses.
An oxidation-prevention layer is formed on the oxidation-reduced region by deposition of a flux on the oxidation-reduced region, application of a solder to the flux, and blowing of a heated gas by the solder.
Improved product strength, flow and brazing characteristics
