Containing almost 1 million Z-axis nickel fibers per square cm, NTP thermoplastic films are as electrically conductive as solder and have a lower total thermal resistance than silver filled adhesives.
btechcorp introduces the NTP series of Z-axis electrically and thermally conductive thermoplastic film adhesives. Containing almost 1 million Z-axis nickel fibers per cm2, NTP films are as electrically conductive as solder and have a lower total thermal resistance than silver filled adhesives.
NTP provides solar cell to bus bar Z-axis
electrical and mechanical connections and is
laminated at the same time as the solar panel
assembly, thus saving the extra process steps
needed for soldering. High lap shear and peel
strength and its very low modulus allow it to absorb
much higher CTE and bending stress than solder.
Since NTP strongly bonds to plastic and all metal
substrates, it has excellent mechanical as well as
electrical properties for Z-axis connection of printed plastic circuits. Very high
X-Y electrical insulation means that NTP can be used for circuits with as little as 200 micron spacing between pads.
The NTP series uses three different thermoplastic resins to offer application flexibility in bonding temperature and thermal cycling capability. Bonding temperature options are 125°C, 150°and 185°C. Thermal cycling capability ranges from -50°C to +90°, +130°C and +160°C.
