Patent ID: 8257794

Claim:
A discontinuous capillary coating method, comprising: providing at least one capillary tube, at least one capillary tube holder, at least one traversing mechanism, and at least one coating substrate; filling the capillary tube with a coating material and disposing the capillary tube on the capillary tube holder; activating the traversing mechanism to enable the capillary tube to approach and contact the coating substrate, allowing the coating material in the capillary tube to contact the coating substrate, wherein the coating material is capable of wetting the coating substrate; moving the capillary tube holder upward to a specific position, thereby connecting the capillary tube to the coating substrate through a liquid bridge of the coating material; moving the capillary tube holder or coating substrate by the traversing mechanism, wherein a coating operation is performed by capillary action, and a liquid film on the coating substrate is formed; and activating the traversing mechanism to separate the capillary tube from the coating substrate, cutting off the liquid bridge between the coating material and the liquid film, and forming at least one discontinuous liquid film.
