Abstract

PURPOSE: To make the coordinate measurement work simpler and more efficient the programming procedure of an electronic parts mounting machine by indicating parts mounting target marks at the mounting position of each electronic parts by silk printing.
CONSTITUTION: For the printed wiring board used for the programming procedure of an automatic electronic parts mounting machine in a printed wiring board assembling process, electronic parts mounting target marks 4 are indicated at the mounting position of each electronic parts by silk printing. A coordinate measuring tool is first moved to a reference hole 5 which is a coordinate reference and (X, Y) coordinate data are reset to (0, 0) when the programming for the electronic parts mounting machine is performed. Then the coordinate measuring tool is moved to the mounting target mark 4 to the electronic parts to be mounted next and, upon the completion of the movement, the position is registered as mounting coordinate data. The next coordinated are measured in the same way.
