What can I use to solder a heat sensitive
component on to my circuit board?
With the shift to lead free soldering, heat sensitive
components will become more of an issue. Components
will distort or become permanently damaged if the
soldering process exceeds its maximum reflow
temperature. Plastics, for example, are susceptible to
either degrade or melt at high temperatures. Both these
can degrade or destroy the function of the component.
As lead-free solders require a higher reflow temperature
than tin/lead, a wide variety of components may be
unsuitable for use unless component manufacturers
have modified these parts to increase their maximum
reflow temperature.
Cold soldering
For low volume production and maintenance,
using Silver Conductive Epoxy
makes the most economical sense.
Lead-free solders are different to tin/lead in several ways, the main differences being:
Higher melting point – typically 30 - 40°C higher
Inferior wetting properties, mid-chip solder balls
Higher surface tension – increased risk of tombstoning and bridging
(see page 2 for more on tombstoning and bridging)

This two part silver epoxy offers high electrical conductivity
and strong conductive bonding. Use in place of traditional
soldering on heat sensitive components. Good for repairing
defective traces and creating jumpers on boards. Can be
used as an effective heat sink adhesive. This Conductive
Silver Epoxy comes in two 7g syringes.

soldering after all other components have been
attached. These soldering techniques do not heat
components to as high a temperatures as SMT but
require space around the component.

requires significant circuit design changes.
