●Over 20 minutes elapsed after the current temperature reaches the preset temperature of the heater,
dummy dispensing teach should be performed.
●Confirm ejection before dummy dispensing teaching (more than 10 seconds).
●As for the reconfirmation of dummy dispensing, be sure to confirm more than 10 points.

Solutions to defective adhesive-dispensing
■When stringiness (part of an adhesive forming filaments) occurs
Lower the adhesive viscosity and raise the set nozzle temperature so as to improve adhesive flow control
and fluidity.
(Set on the adhesive library editor)
Adjust the head height position so that the XY travel starts after the flow of adhesive stops.
(Set in the dispensing condition setting)
Lower the nozzle rising speed. (Set in the dispensing condition setting)
■When adhesive splatters
Raise the adhesive viscosity and lower the set temperature of the temperature control unit so as to
prevent adhesive from splattering.
(Set on the adhesive library editor)
Lower the nozzle rising speed. (Set in the dispensing condition setting)
■Others
Decrease the nozzle lowering speed so as to reduce damages to a PCB and components on its
reverse side.
(Set in the dispensing condition setting)
●The setting is configured with NPM-DGS. (→[NPM-DGS] Operating instruction)
