Screen Printers

The Solar Power Laboratory has three screen printers, two from MPM and one from AMI. One MPM screen printer is used for experimental pastes, and the other MPM printer is used for routine screen printing of the aluminum back surface field. The AMI printer is used for silver paste printing and is capable of optical alignment for more automated screen printing. In all cases, the maximum wafer size is 156 mm, and all of the printers are capable of operating with both mono and multicrystalline wafers.
