Interdigital electrodes are the hyperfine circuits obtained by electrochemical processing, the line width and spacing are greater than or equal to 3μm. They are used as core components of sensors, surface acoustic wave filters, microwave RF and other electrical signal transmission devices. They are also widely used in mobile communications, medical testing, environmental monitoring and other important areas.
Line width>3 μm
Line spacing >3 μm
Metal layer thickness >1 μm
Temperature resistance test: -20~150℃
Metal layer: Ni, Cu, Au, Ni-P, Au-Sn
Substrate: Aluminium Oxide, Aluminium Nitride, glass, silicon wafers, piezoelectric ceramics, microwave dielectric ceramics, plastic films.
With techniques from Sun Yat-sen University Electronic Packaging Electrochemistry Lab, our processing accuracy(line width and spacing) can reach 3μm.
