context_page_description: Chip on board is a method of circuit board manufacturing in which the integrated circuits are wired, bonded directly to a printed circuit board, and covered by a blob of epoxy. By eliminating the packaging of individual semiconductor devices, the completed product can be more compact, lighter, and less costly. In some cases, COB construction improves the operation of radio frequency systems by reducing the inductance and capacitance of integrated circuit leads.
  COB effectively merges two levels of electronic packaging: level 1 and level 2, and may be referred to as "level 1.5".

In some cases, COB construction improves the operation of radio frequency systems by reducing the inductance and capacitance of integrated circuit leads. 
  COB effectively merges two levels of electronic packaging: level 1 (components) and level 2 (wiring boards), and may be referred to as "level 1.5".
