System and methods for data-driven control of manufacturing processes

Systems and methods for implementing hybrid, closed-loop control that generates control values for processes defined by a limited number of function evaluations and large amounts of process and measurement noise. The described control system is applied to a stencil printing process for applying solder paste to an electronic medium such as a printed circuit board or semiconductor wafer. The control system is defined by a hybrid approach. A first, coarse algorithm is used to rapidly produce the value of a stencil printer control value resulting in a solder paste deposit having a volume within predetermined acceptable limits. After the coarse algorithm no longer produces solder paste deposits closer to a desired volume, a second, more refined estimator is used to fine tune the process. An additional transitional algorithm may be added between the coarse algorithm and refined estimator. The coarse algorithm may be implemented with a constrained-conjugated gradient search, and the refined search may be a implemented using a least-squares affine estimator or a quadratic estimator. The transitional algorithm may be implemented using a block version of a least-squares affine estimator.

Print job assignment method allowing user-prioritization

A method implemented in a print job management apparatus for processing print jobs in a multiple-printer print shop environment is described. Each print job specifies job ticket parameters representing printing requirements. Each received job is processed by comparing the printing requirements of the job with capabilities of the printers. If a printer cannot satisfy all printing requirements of the job, it is eliminated as a candidate printer. Then, from all printers that can satisfy all printing requirements of the job, one printer is selected based on a pre-defined priority preference and the job is submitted to the selected printer. The printer priority preference is created by the operator based on cost and other factors. The operator can also select an alternative execution mode where, among all printers that can satisfy all requirements of the job, the one with minimum wait time is selected.

Date Dec. 19, 1996A method of screen printing on to a hard non-absorbent substrate (1) involves using a screen (10) which has an ink permeable area (B) whose pattern corresponds to whatever is to be printed. The area B is divided into two parts (X and Y). Part X is of normal, maximum, ink carrying capacity and part Y is of reduced ink carrying capacity. The ink carrying capacity of the reduced ink carrying capacity part Yis determined by the extent to which it is coated with ink / impenetrable emulsion (20), the size of the pores (18) in the screen (10) and the type of ink used. The ink carrying capacity of the part Y reduces with distance away from part X. The emulsion coating (20) may be in the form of dots (200), with the dots (200) increasing in diameter with distance away from part X. During printing, the reduced ink carrying capacity part Y is located over the edge region (E) of the substrate (1), and the substrate is printed up to but not on to its edge (6).
