What is Chip On Board Technology (COB)?

COB technology simplifies electronic device assembly by placing the microchip directly onto the circuit board. This direct bonding can be achieved through wire bonding or solder bumps. For a deeper understanding of COB’s basics, Electronics Hub offers a comprehensive guide that breaks down the technology and its application.

A Short History of COB

COB technology emerged in the late 20th century as the electronics manufacturing industry sought compact, efficient circuit integration methods. The evolution from surface mount technology (SMT) and through-hole technology (THT) to COB represents a significant leap in manufacturing. Historical insights and the technological progression are well-documented in IEEE’s electronic library.

The Role of COB in Electronics

From LED displays to automotive applications, COB technology has broadened the horizons of electronics manufacturing. Its influence on LED technology, for example, has led to devices that are not only brighter but also more energy-efficient. ScienceDirect publishes research articles detailing COB technology’s impact on the LED industry and beyond.

The Benefits of COB

COB technology brings several advantages to electronic devices, including reduced size and improved thermal management. For those interested in the technicalities of how COB enhances device performance and longevity, the American Society of Mechanical Engineers (ASME) provides resources and papers on thermal management solutions in electronic packaging.


COB technology is at the forefront of driving the electronics industry towards more integrated, efficient, and sustainable solutions. As we advance, the role of COB in fostering innovations in IoT and AI is undeniable.
