Earth Leakage Circuit Breaker (ELCB) PCB Ass’y
COBON TECH supplies complete PCB Ass'ys that combine its proprietary COB (Chip-on-Board)-based leakage current detection circuit with carefully selected electronic components. Customers can directly integrate the PCB Ass'y into their products without the need for separate circuit development, reducing development time and improving productivity. In addition, consistent quality and stable leakage current detection performance can be ensured.
COB(Chip-on-Board)
This solution integrates the core leakage current detection circuit into a single compact module by directly wire bonding semiconductor chips in wafer form onto a PCB and applying epoxy molding. By integrating the core detection circuit using COB technology, it enables product miniaturization and cost reduction, while a simplified production process provides high productivity and excellent quality reliability. In addition, minimizing the number of key components reduces the possibility of defects and helps maintain stable performance.
It is mainly applied to leakage current detection circuits in Earth Leakage Circuit Breakers (ELCBs), Earth Leakage Relays (ELRs), and various electrical and electronic devices. By quickly detecting leakage current, it plays a key role in protection systems designed to prevent fires and electric shock accidents.
