DPC Ceramic By Substrate Thickness


The DPC Ceramic comes with a substrate thickness of 0.25mm, which means that it can withstand high temperatures without cracking or deforming.


DPC Ceramic with 0.38mm substrate thickness is a ceramic with high thermal conductivity, high hardness and high strength fro better dependability of devices.


We’ve taken our 0.5mm DPC Ceramic and paired it with a 0.5mm substrate thickness for an ultra-durable and long-lasting printed circuit boards.


One of the most commonly used DPC Ceramic in electronic devices, such as mobile phones, computers and other consumer electronics products.


High-quality, high-performance DPC ceramic with a substrate thickness of 1.5mm. Made from a material that is resistant to moisture and corrosion.


The ceramic substrate is made of high quality, highly durable materials that can withstand any type of weather or environment you can throw at it.

Identification of DPC Ceramic

Direct Plated Copper (DPC) ceramic PCBs are the best option for high-speed, high-power applications.

DPC ceramics are made by plating a thin layer of copper on top of the ceramic, followed by a thick top layer of nickel, which forms the outermost layer of the final product. This process is completed in a single step, making these boards much more cost effective than other boards like FR-4 or Rogers sheet metal products.

These products have excellent thermal conductivity due to their low resistivity and high thermal conductivity values. They have much higher current density capability than other ceramic substrates due to their high power handling capabilities.

DPC Ceramic for High-Power Applications

DPC Ceramic for High-Power Applications

Direct Plated Copper (DPC) is a  developed technology that can be applied to high-power PCBs. The DPC process allows for the fabrication of high-power semiconductor devices with increased power density and higher reliability.

The Direct Plated copper ceramic PCB also has a high thermal conductivity and excellent electrical insulation performance. It is suitable for high-power applications such as inverters, power supplies, and electronic components.

In addition, the material is highly stable with good mechanical strength and corrosion resistance. The electrical properties of direct plated copper ceramic are superior to those of other types of dielectrics such as glass epoxy or other ceramics.

How to choose between DBC and DPC?

Choosing between a Direct Plated Copper PCB and a Direct Bond Copper PCB can be difficult, but the decision really comes down to what you want your final product to look like.

A DBC board is made by coating copper onto an epoxy-based board before applying a thin layer of solder. This makes it ideal for prototyping and small-batch production runs because it costs less than other methods, and it’s also easy to work with.

A DPC board is made by applying solder directly onto an epoxy-based board before applying another layer of solder over top of that. This method creates a more durable product with more consistent results than other methods, which makes it great for large-scale production runs or projects where reliability matters.

DPC Ceramic Fabrication

Superior CTE and High Thermal Conductivity

The thermal conductivity of a material is the ability of that material to conduct heat. The higher the thermal conductivity, the better it will be at transferring heat away from a device or system.

DPC ceramic printed circuit boards (PCBs) have superior thermal conductivity compared to other PCBs, which means they can dissipate heat better.

This means that devices using DPC PCBs can run cooler and with less risk of malfunction or damage due to overheating.

The combination of high thermal conductivity and low CTE means that DPC PCBs are an excellent option for devices that need to operate under extreme conditions such as high temperatures or in space where there is little air pressure.

Low Cost and High Performance DPC

DPC ceramic printed circuit boards (PCBs) are an excellent choice for a wide range of applications, because they are both low cost and high performance.

DPC ceramic printed circuit boards are made from ceramic material, which is highly resistant to heat and flame. They also offer the best electrical insulation properties in the industry. As a result, they can be used in applications where other PCBs would be damaged or destroyed by heat or fire.

DPC ceramic printed circuit boards are also very durable and long-lasting, so you don’t have to worry about replacing them too often. This makes them an excellent choice for many different types of electronic devices that require regular use over long periods of time.

OEM & ODM DPC Ceramic Applications


DPC ceramic printed circuit boards are used in high-brightness LED lighting applications. They are a great alternative to glass fiber-reinforced epoxy boards and aluminum boards.

Microwave Devices

DPC ceramic printed circuit boards are a great choice for microwave devices. They have excellent thermal, electrical, and mechanical properties that make them perfect for this type of application.


Ceramic printed circuits boards are used in automobiles for various purposes such as controlling engine functions, monitoring performance, air conditioning and regulating fuel consumption.

Solar Cell Component

DPC ceramic printed circuit boards for Solar Cell Component are the most popular and widely used in the world. They are mainly used in solar cells, space satellites, power generators, and other fields.
