Paste provides the convenience of fluxing and soldering
in one step. It is a mixture of fine grade alloyed solder
powder and a highly active zinc chloride flux vehicle.
It is for non-electronic applications and available in
most common soldering alloys including lead free alloys.
Commercial Solder Paste
has a thickening agent that gives the paste the ability
to cling to surfaces. Typical metal content is 75% by
weight. It is applied by brush, spatula, or syringe type
dispenser. Reflow is accomplished in an oven, by torch,
or by iron.
The highly active
zinc chloride based flux system is appropriate for many
types of industrial solder alloys and base metals. Warm
water is used to clean any residues, especially for critical
metal surfaces. It is not appropriate for sensitive electronic
Considerations - Personal protection should
include eye protection, chemical resistant gloves, and
apron/lab coat. Avoid contact with skin and avoid breathing
fumes. Use in a well ventilated area. Refer to the Material
Safety Data Sheet for more information.
Pastes - Store between 4°
and 25°C. Stir 1 to 2 minutes prior to use. Keep covered
when not in use. Do not use if the paste is dried out.
Dispose of used paste per all appropriate laws and regulations.
