PRODUCT DESCRIPTION
C502 provides the following product characteristics:
C502 cored solder wire has been specially formulated to
complement no clean wave and reflow soldering processes.
C502 is also well suited for soldering applications requiring
high melting temperature alloys.
TYPICAL PROPERTIES
Solder Cored Wire
ALLOYS:
The alloys used in C502 cored solder wires conform to the
purity requirements of the common national and international
standards.
FLUX:
C502 solid flux is based on modified rosin and carefully
selected activators. In practice they exhibit a mild rosin odor
and leave a small quantity of clear residue.
DIRECTIONS FOR USE
Soldering with C502 does not require any special methods or
deviation from standard hand soldering practices.

Cleaning:
C502 flux cored solder wire has been formulated to leave
amber flux residues and resist spitting and fuming. In most
industrial and consumer electronics applications, cleaning will
not be required. The product may, therefore, be used to
complement a no-clean wave soldering or reflow process or to
allow repairs to cleaned boards without the need for a second
cleaning process. In high-reliability applications, the residues
should be removed.
Should cleaning be required, this is best achieved using
SC-01™ cleaner.
