Table 3:

Validated uses of each board with the cutting methods described.

Preparation Method	Wide Board	ZIF	Flex Array
Nd:YAG	Impedance, SEM, acute ePhys	Impedance, SEM, acute/chronic ePhys	Impedance, SEM, acute/chronic ePhys
Blowtorch	Impedance, SEM, acute ePhys	Impedance, SEM, acute/chronic ePhys	Impedance, SEM, acute/chronic ePhys
UV Laser	Not yet validated	Impedance, SEM, acute/chronic ePhys	Not Viable

All cutting methods included electrodeposition of PEDOT:pTS. ‘Not Viable’ indicates that a form factor of the design prevents this tip treatment from being tested at this time (i.e., fiber pitch). Abbreviations: Neodymium-doped yttrium aluminum garnet; SEM = scanning electron microscopy; ePhys = electrophysiology; ZIF = zero insertion force.
