Even the cost for ALN will be more expensive than the AIO203, ALN has the high conductivity and the expansion coefficient matching Si, which makes the customers still choose it as the material for their products, Here you can see the details for the ALN material and the Ceramic capability for FX PCB.



What is the COB PCB

COB (Chip on Board) PCB is a type of integrated circuit packaging technology that involves mounting bare semiconductor chips directly onto a circuit board. This technology has gained immense popularity in recent times due to its numerous advantages over traditional SMD (Surface Mount Device) assembly techniques.

COB technology results in a compact and reliable PCB design that saves space, reduces power consumption, and enhances the overall performance of electronic devices. The process involves placing the semiconductor chips directly on the circuit board, which eliminates the need for bonding wires and reduces the number of components required to build the PCB. This is achieved by using a special encapsulation technique that connects the chip to the board while protecting it from external factors such as moisture, dust, and mechanical stress.

What are the advantages of COB PCB?

COB PCB technology offers several advantages over traditional SMD techniques.

Firstly, it increases the thermal performance of the device as heat dissipation is better facilitated. This allows faster data processing and reduces the risk of failure due to overheating.

Secondly, it enhances the reliability of the device by reducing the number of components required and eliminating the need for wires, which are prone to damage and breakage.

Thirdly, it improves the accuracy and precision of the device due to the absence of wire bonding, resulting in fewer signal losses and improved signal integrity.

COB PCB technology has become the preferred option for various electronic applications such as mobile devices, automotive electronics, and lighting applications. Due to its advantages, it has also become an essential part of the Internet of Things (IoT) technology, where space, reliability, and performance are critical requirements.


Summing up, COB PCB technology has revolutionized the electronic industry, providing numerous advantages over traditional SMD assembly techniques. Its compact size, reduced power consumption, enhanced thermal performance, improved reliability, and increased accuracy have made it a preferred choice of designers for various electronic applications.
