The screen printer according to replace Printed Circuit Board mask and backup zig simultaneously using this device, and automatically transfers a mask and a method for automatic replacement of backup zig simultaneously

摘要

screen printer of the present invention is a printed circuit board in accordance with the backup jig and replace the mask At the same time relates to a method for automatic replacement of a device at the same time and using the same mask jig and Backup automatic replacement, spare unit and a back mask jig screen by integrating the spare unit is preferably a printed circuit board corresponding to the production of the new printer by ensuring that the corresponding back of the spare fixture on the mask and the mask at the same time, the transition to the production of unwanted waste of time and manpower and therefore without the hassle of replacement by a new printed circuit board in the process of replacing the mask with a separate backup jig This enables rapid and efficient productivity through the shortening of the working time and through it is increased, the rate of change of the process conditions, a quick replacement of the mask and the screen printer with automatic backup jig replacement process is not unreasonable due to the human To replace the device and the backup jig and using the same mask to automatically replace the backup jig, and the mask at the same time according to the replacement printed circuit board in a screen printer capable of minimizing product defects caused due to the replacement, according to the same time as automatically minimize relate to. ;
