Patent ID: 7931933

Claim:
A method of providing a substrate with solder paste, comprising the steps of: applying solder paste dots onto said substrate at a plurality of locations; inspecting the results of said application at more than one of the plurality of locations; determining errors of the application based on said inspection, and for an error determined for a position of an application, recording error parameters comprising the size of the solder paste dot, the dot position and/or the dot shape, said step of determining errors further comprising the steps of: estimating for each of the determined errors the time required for performing corrective action using the error parameters for a respective error; calculating the overall time required for corrective action of all determined errors; and evaluating the error parameters of each of the determined errors to decide whether corrective action shall be performed; and if it is decided that corrections shall be performed to said substrate: correcting at least some of said errors by jetting of additional solder paste on said substrate; and transferring said substrate to a component mounting machine.
