Method for generating a jetting program

A computerized method for generating a jetting program for a computer controlled viscous medium jetting machine, and for jetting droplets, where droplet jetting is a non-contact dispensing process using a fluid jet to form and shoot droplets of a viscous medium onto a substrate, comprising the steps of:

• a) obtaining substrate data for a substrate, which is to be provided with deposits and components, wherein each of the deposits is a connected amount of viscous medium applied at a position on a substrate as a result of one or more jetted droplets and each of the deposits is defined by its size in the x and y directions and by its volume;
• b) for each component which is to be placed on the substrate:
• fetching component data for the component from said substrate data;
• and
• selecting a matching predefined deposit pattern, comprising at least one deposit, which matches the number of reception areas of a desired deposit pattern for said component data, wherein the deposit pattern comprises, for the/each deposit, deposit data comprising deposit extension and deposit position;
• and
• if no matching predefined deposit pattern exists, defining a deposit pattern, comprising at least one deposit, for the component data, comprising the step of defining, for the/each deposit, deposit data, which step comprises determining deposit extension and deposit position;
• c) determining a jetting sequence on basis of the deposit patterns;
• comprising the step of converting the deposit patterns to droplet configurations, on basis of the deposit patterns, wherein the step of converting the deposit patterns to droplet configurations comprises automatically determining, without user input other than initiation of the automatic determining operation, how many droplets will be needed to build up a specific deposit, and where within the extension of the specific deposit the droplets should be deposited, and
• d) generating a jetting program on basis of the jetting sequence.

A computerized method for generating data for a droplet deposit jetting program with respect to a computer controlled droplet jetting machine, and for jetting droplets, where droplet jetting is a non-contact dispensing process using a fluid jet to form and shoot droplets of a viscous medium onto a substrate, comprising the steps of:

• a) obtaining substrate data for a substrate, which is to be provided with deposits, each being a connected amount of viscous medium applied at a position on a substrate as a result of one or more jetted droplets and each of the deposits is defined by its size in the x and y directions and by its volume, and components;
• and
• b) for each component which is to be placed on the substrate:
• fetching component data for the component from said substrate data;
• and
• using a computer to select a matching predefined deposit pattern by means of the component data among stored deposit patterns which have previously been defined for different components, the predefined deposit pattern comprising at least one jetted droplet deposit, which matches the number of reception areas of a desired deposit pattern for said component data, wherein the deposit pattern comprises, for the/each deposit, deposit data comprising deposit extension and deposit position;
• and
• if no matching predefined deposit pattern exists, defining a deposit pattern, comprising at least one deposit, for the component data, wherein said defining a deposit pattern comprises at least one of:
• selecting a predefined deposit pattern which is computer adjustable into match, and adjusting the selected deposit pattern into match;
• presenting predefined deposit patterns with an indication of the extent to which they match with said component data;
• and
• receiving input defining a new deposit pattern, comprising, for the/each deposit, deposit data comprising deposit extension and deposit position;
• and
• c) utilizing the deposit data in operation of the droplet jetting machine comprising automatically determining, without user input other than initiation of the automatic determining operation, how many droplets will be needed to build up a deposit and where the droplets are jetted;
• and
• jetting droplets onto the substrate according to the determination of how many droplets will be needed to build up a deposit and where the droplets are jetted.
