The Imprinter 02 is a system for bonding. Three different types of Polymer bonds can be done: PMMA, SU8 and BCB (more information here). It not is possible to mechanically align the wafers. It is also possible to process pieces.

The user manual, quality control procedure and results, user APV(s), and contact information can be found in LabManager.
