Requirements | Reasons of the Requirements | Characteristics of SUMIKASUPER LCP | ||||
Compact size and low weight | For power saving and high sensitivity |
|
||||
Reading signals accurately | If resonation occurs at less than the operating frequency ( - 20 kHz), the signal can not be read. The resonant frequency of low specific gravity and high modulus material is high. |
|
||||
Low cost | Can be mass-produced through injection molding.As dip soldering can be performed during the assembly process (350 - 400 °C x several seconds), the process of inserting metal terminals is no longer required as cost. |
