Abstract

Embodiments of the present invention provide a multiple head dispensing system having independently controlled dispensing heads. Each of the dispensing heads may be independently controlled to provide simultaneous, asynchronous operation and to allow dispensing of different materials onto substrates. Independent control of the dispensing heads is accomplished under the control of a controller in conjunction with a plurality of gantry systems, each of which positions one of the multiple dispensing heads over a substrate that is to receive dispensing material. In some embodiments, each gantry system utilizes two drive mechanisms, arranged in parallel, that provide movement of the dispensing head over an x-y plane. Multiple conveyor systems are utilized that allow parallel processing of work products in the dispensing system.

Claims9

Dependent claims

A control system for controlling an apparatus that performs at least one operation on at least one substrate, the control system comprising:

a user interface for coupling to a user interface device through which a user of the apparatus can monitor and control operation of the apparatus;
a chassis server including:
a connection system that provides an interface between the chassis server and the user interface;
a message system, that transfers messages between systems within the chassis server;
a chassis management system that controls the apparatus to perform the at least one operation on the at least one workpiece;
a pattern management system that contains at least one recipe defining characteristics of the operation to be performed on the workpiece, and provides messages over the message system to the chassis management system so that the chassis management system controls the apparatus based on the characteristics of the at least one recipe.
