corrosive flux वाक्य

In electronics non-corrosive fluxes are often used.
In high humidity, even non-corrosive flux might remain slightly active, therefore the flux may be removed to reduce corrosion over time.
The use of ultrasonic soldering is expanding, since it is clean and flux-less in combination with active solders being specified for joining assemblies where either corrosive flux can be trapped or otherwise disrupt operation or contaminate clean production environments or there are dissimilar materials / metals / ceramic / glasses being joined.
