Overview
The MTI EQ-SPC 2 Screen Printer can be used for quickly producing patterns using various paste types. Using the same process as t-shirt screen printing, mask like designs can be produced using similar steps to photolithography: degrease the screen, coat the screen with light sensitive emulsion, and burn (expose) the screen and emulsion to UV light with the mask aligner. The screen can then be used as a mask for pattern transfer with a paste and the screen printer setup. The Cleanroom has developed a process using silver paste for solar cell metal contacts and screen-printed electrodes using the screen printer.Â
