Film ThicknessThe key blessings of thick film power resistors over Wirewound ar smaller size, ar accessible at considerably lower price (including tooling cost), have lower inductance and improved thermal management. Thick film resistors ar thus smaller, have a quicker frequency response and ar higher suited to heat sinking applications. Thick film technology additionally delivers higher resistance values and better voltage rating than Wirewound resistors.
The major advantage of thick film technology in high power applications is that the high thermal physical phenomenon of the ceramic (Alumina) substrate creating it ideal for applications wherever high power dissipation is needed in an exceedingly little space. The substrate material suggests that it's a wonderful match with the atomic number 13 material in heat sinks and is with chemicals inert and automatically stable.Film Thickness
Conclusion
Although Wirewound resistors do supply higher exactitude (improved tolerance), higher stability and lower values it's typically at the expense of abundant larger footprint and better inductance than constant thick film device. Any Wirewound resistance is essentially a coil of wire (an inductor) and though selection of fabric will limit the impact of the high inductance it remains a significant disadvantage.Film Thickness

The situation that coating film?s thickness can be controlled at a predetermined value is called as the film thickness controllability.
ReplyDeleteBecause the vacuum sputterin?s discharge current and target current can be controlled separately, so by controlling the target current can control the film thickness.
