Apparatus and method of generating control parameter of screen printer

An apparatus for generating a control parameter of a screen printer, the apparatus comprising:

• a memory that stores:
• a simulation model configured to derive predictive inspection information on printed states of a plurality of virtual solder pastes based on a plurality of control parameters of the screen printer;
• and
• at least two algorithms configured to generate a plurality of candidate control parameters for the screen printer;
• a communication circuit configured to receive first inspection information on a plurality of solder pastes, the plurality of solder pastes being printed by the screen printer based on a first control parameter;
• and
• a processor electrically connected to the memory and the communication circuit,
• wherein the processor is configured to:
• obtain first predictive inspection information on a printed state of a first virtual solder paste by applying the first control parameter to the simulation model;
• generate a plurality of first candidate control parameters based on the first predictive inspection information and a first algorithm of the at least two algorithms;
• generate a plurality of second candidate control parameters based on the first predictive inspection information and a second algorithm of the at least two algorithms;
• determine a plurality of second control parameters among the plurality of first candidate control parameters and the plurality of second candidate control parameters based on whether a difference between the first inspection information and the first predictive inspection information is greater than a predetermined threshold value;
• and
• transmit the plurality of second control parameters to the screen printer via the communication circuit.
