Parameters suggestion system of solder paste screen printer including method, device employing method, and non-transitory storage

A device for deciding product printing parameters, the device comprising:

• at least one processor;
• and
• a storage device storing one or more programs which when executed by the at least one processor, causes the at least one processor to:
• establish a solder-printing database of a predetermined product, wherein the solder-printing database comprises a plurality of printing parameters of an SPSP for producing the predetermined product and a measuring parameter of an SPI corresponding to each of the plurality of printing parameters;
• train a first prediction model of the predetermined product between printing parameters of the SPSP and measuring parameters of the SPI based on the solder-printing database;
• establish a product database of different product specifications, wherein the product database comprises product sizes, printing parameters of the SPSP, and measuring parameters of the SPI;
• train a second prediction model between product specifications and measuring parameters of the SPI based on the product database of different product specifications;
• estimate specification influences of products with different product specifications based on the second prediction model;
• obtain predicted measurements of the SPI of the products with different product specifications under multiple sets of printing parameters based on the first prediction model and the specification influences of the products with different product specifications;
• establish an objective function based on the predicted measurements of the SPI of the products with different product specifications;
• and
• input a product specification of an objective product and an expectation measuring parameter of the SPI to the objective function to output a printing-suggestion parameter corresponding to the objective product.

A non-transitory storage medium having stored thereon commands that, when executed by a processor of a device, causes the device to perform a method for deciding product printing parameters, the method comprising:

• training a first prediction model of the predetermined product between printing parameters of the SPSP and measuring parameters of the SPI based on the solder-printing database;
• establishing a product database of different product specifications, wherein the product database comprises product sizes, printing parameters of the SPSP, and measuring parameters of the SPI;
• training a second prediction model between product specifications and measuring parameters of the SPI based on the product database of different product specifications;
• estimating specification influences of products with different product specifications based on the second prediction model;
• obtaining predicted measurements of the SPI of the products with different product specifications under multiple sets of printing parameters based on the first prediction model and the specification influences of the products with different product specifications;
• establishing an objective function based on the predicted measurements of the SPI of the products with different product specifications;
• and
• inputting a product specification of an objective product and an expectation measuring parameter of the SPI to the objective function to output a printing-suggestion parameter corresponding to the objective product.
