摘要:
Printheads may be utilized to produce at least one gridline on an upper surface of a target substrate, in particular for producing a pattern for a solar cell structure, wherein the printheads may enable a printing in the forward and an opposite backward direction at the same time to, for example, increase the relative speed the printing procedure and to improve the screen or stencil printing process.

A feedback information generation method for a solder inspection apparatus includes: receiving an input of information on the number of buffers which are disposed between the solder inspection apparatus and a screen printer for printing solder on printed circuit boards and are configured to support the printed circuit boards to be introduced into the solder inspection apparatus so as to put the printed circuit boards on standby; generating feedback information by using the input information and an inspection result of the printed circuit boards by the solder inspection apparatus; and transmitting the feedback information to the screen printer. Feedback information may be generated in consideration of the number of buffers, thereby preventing the feedback information from being excessively generated as well as ensuring the accuracy of the feedback information.

A screen printing apparatus (1) includes a printing execution unit (20A, 20B) that performs screen printing on a substrate (W). At least one substrate support table (10A, 10B) that is provided movably along a specific direction (Y) orthogonal to the conveying direction (X). A table drive mechanism (4A, 5A, 4B, 5B) that moves the substrate support table (10A, 10B) at least between substrate entry and exit positions (EnP1, EnP2, ExP1, ExP2) along a specific direction (Y). The substrate entry and exit positions (EnP1, EnP2, ExP1, ExP2) are set asymmetrically with respect to the specific direction (Y). A printing execution unit drive mechanism (210) is provided to drive the printing execution unit (20A, 20B) along the specific direction (Y). A control unit is provided to control the printing execution unit drive mechanism (210) so that the printing execution unit (20A, 20B) is driven to set the printing position (SP1, SP2) on a substrate conveying path (PH1, PH2) needed for the substrate support table (10A, 10B) to move from the substrate entry position (EnP1, EnP2) to the substrate exit (ExP1, ExP2).
