Abstract
A solder paste inspection machine carries out the steps of automatically generating inspection data for solder paste deposits, automatically determining a squeegee direction of travel for said paste deposits. It associates the squeegee direction with the inspection data, and feeds the inspection data back to a solder paste printer with an indication of squeegee direction. The direction is determined from three-dimensional range maps, the direction of squeegee travel being in the direction of upward slope.
Claims12
A solder paste inspection machine comprising a camera for capturing images of a substrate with printed solder paste, and an image processor for analysing the images to generate an indication of quality of the solder paste deposit operation, wherein a squeegee direction identification function automatically determines squeegee direction for paste deposits, and a feedback controller routes feedback to a paste machine, said feedback identifying the squeegee direction used for the deposits.
A method of operation of a solder paste inspection machine comprising the steps of:
- automatically generating inspection data for solder paste deposits, automatically determining a squeegee direction of travel for said paste deposits, and associating said squeegee direction with the inspection data, and feeding the inspection data back to a solder paste printer with an indication of squeegee direction.
