导电或绝缘
The AlN mounts can be metallised with the option of making the mount conducting or insulating. For conductive AlN, metallisation is deposited onto at least two of the side walls as well as the top and bottom surfaces. The thickness of the side wall metallisation is tailored depending on the electrical load to be carried.
Metallisations
Various metallisation schemes can be applied, the standard is TiW/Ni/Au.
The Au, Ni layer thicknesses depend on the application. The gold is primarily used to provide the electrical conductivity on the sidewalls and is nominally 0.2 µm thick on the faces and a total of 0.3~0.5 µm thick on the walls. To ensure the gold is properly covered the nickel barrier layer is usually also specified at 0.1µm on the faces. Generally for gold wire bonding 0.5µm minimum of gold is required. A standard specification for the top and bottom faces would be:

Soldering only required 0.1TiW / 0.1Ni  / 0.2Au     

Au wire bonding required 0.1TiW / 0.2Ni / 0.5Au

Pre-deposited AuSn

可以在顶面和底面中的一个或两个上施加薄的真空沉积的AuSn层。标准合金比率标称为75Au / 25Sn,通常为~3.5-5.5微米厚。合金比例也可以根据具体应用进行调整。
