Use of DCB ceramic PCB

A DCB ceramic PCB is a type of circuit board technology used in high-power and high-temperature applications. DCB ceramic PCB is used when a high copper thickness is required (140–350 mm). The copper is bonded to the ceramic substrate on one or both sides using a high-temperature oxidation process. It is designed to provide efficient thermal management and electrical isolation for electronic devices.



DBC is often a two-layer process, where the back of the substrate is a solid and unfeatured sheet of copper and where the top copper layer is structured using chemical etching and is performed to develop the electrical circuit traces.

DCB ceramic PCBs consist of a ceramic substrate that is metalized with a layer of copper, which is directly bonded to the ceramic substrate using various methods such as high-temperature brazing or direct copper laser sintering. This direct bonding ensures excellent thermal conductivity between the copper traces and the ceramic substrate, allowing for effective heat dissipation.

DCB ceramic PCBs have high mechanical strength, mechanically stable shapes that have the highest strength, fine thermal conductivity, and excellent electrical isolation. They come with excellent thermal cycling capabilities up to 50,000 cycles and high reliability that can be etched to various layouts like a normal FR4 PCB.

The advantages of Ceramic PCBs are:

  • It has Higher thermal conductivity.
  • They have a higher thermal expansion coefficient.
  • It comes with a stronger and lower-resistance metal film and an alumina ceramic circuit board.
  • They also have good solderability on the substrate, which is good, and use high temperatures.
  • Comes with good insulation and low high-frequency loss.

DCB ceramic PCBs have a thermal expansion coefficient that is close to that of silicon chips. The best technology provides you with advanced, high-precision printed circuit boards such as heavy copper, mixed layer, high TG, HDI, high frequency, impedance-controlled boards such as Aluminum PCB, Copper PCB, and so on.

Understanding PCB and PCBA

Image
PCB (Printed Circuit Board) and PCBA (Printed Circuit Board Assembly) are two different terms used in the electronic industry. These are two distinct things, which should never be used interchangeably. The difference lies in the functionality of these two units – while PCB is a blank circuitry board, PCBA has all the necessary electronic components for the board to function as intended. A PCB is not functional because it lacks the required components. These are two different aspects of the same process. A PCB provides the bases to build a PCBA. Let’s take a closer look at them. PCB Modern electronic devices use PCBs as their core. They provide mechanical support and electrical connectivity to the components. The boards are made of laminate materials like fiberglass and composite epoxy, with conductive pathways to connect different parts of the board. These pathways are printed onto the board as per the predetermined design of the PCB. An aluminum core PCB features a thin layer of
