DROPLET DEPOSITION APPARATUS

摘要

Droplet deposition apparatus comprises a fluid chamber comprising an actuato r actuable by electrical signals to effect ejection of droplets from the fluid chamber, a drive circuit for supplying the electrica l signals; and a conduit for supplying droplet fluid to said fluid chamber, the drive circuit being in substantial thermal contact with the conduit so as to transfer a substantial part of the heat generated in the drive circuit to the droplet fluid.
