Since 1975, Tecan has been supplying highly accurate and durable single (for 4 or 5 part stacks) and multi-level (for 2 part stacks) crystal masks to major crystal manufacturers. Finished masks, produced in stainless steel and nickel with optional gold-plating, typically withstand post-deposition cleaning for up to 10 times longer than conventional masks. Tecan also supplies masks with appropriate framing systems, manufactured in aluminium.
