Overview
The C-721 dispensing system is factory-equipped with two or three independently configured substrate
heating stations which provide complete thermal control during all phases of the dispensing process (a
third heating station is optional). Part heater, or tooling temperature, is controlled by the Fluidmove for
Windows NT (FmNT) dispensing software. Two types of part heaters are currently available for the
C-721 system:
• Contact heat tooling
• Impingement heat tooling
Contact Heaters
Contact heat ensures reliable, software-managed substrate heating for fluid dispensing. Contact heat is
preferred for applications in which the tooling must contact the substrate for proper heating to occur, and
for which contact with the heater will not damage the substrate. Asymtek’s two-piece tooling for contact
heating features an interchangeable top plate, custom configured for a variety of substrates that are
transported using standard-width carriers (Figure 15-1). Removable top plates are machined to customer
specifications, and can be replaced as your package requirements change. The heater delivers up to 1,200
watts of power for rapid substrate heating, with vacuum fixturing of parts.
