Owing to the diffusion of the whisker material and the melting of silicon surface into the surface at the contact point, the PN junction is created there (figure 3). Due to the very small value of capacitance at the point contact junction, these junctions are very helpful for working at high frequencies (10 GHz).

High-pressure Die Casting > ENGINEERING

2020/5/7· Long die life, coined with a high level of automation, makes die casting very economical for high-volume production. Thin walls of just 0.4mm are possible. In fact, thinner walls generally improve material properties as the more rapid cooling reduces the size of crystals in the solidifying metal, resulting in a fine grain structure.
