What Is Dupont PCB?
Dupont PCB is one kind of Printed Circuit Board that has double-sided polyimide, copper-clad, cover lays, bond plays, and prepreg laminate on the board. This laminate is constructed by high heat and pressure. That will provide more protection on Dupont PCB and be useful for high-intensity applications.
What Are The Dupont PCB Laminates?
Dupont laminates are the layer of Polyimide laminates that are established on both sides of the PCB. That’s why this is known as Dupont PCB Laminates. PCBMay offers outstanding Dupont laminates in order to increase the electrical, mechanical, chemical, and thermal properties of PCB.
Which Materials Are Used To Fabricate Dupont PCB?
There are several materials used to fabricate Dupont PCBs. Dupont laminate is fabricated by layering some materials on the PCB materials. Usually, Polyimide and Copper Clad Laminateare construction materials for the Dupont PCB.
Polyimide is a durable and plastic-type PCB laminate material. It has a high heat-resistant capability. For this reason, Polyimide laminate is used on the fiberglass after soaking by resin.
● Copper Clad Laminate
Another popular material to fabricate Dupont Printed Circuit Board is Copper clad. It has high conductivity capacity as well as electrical capacity. That property helps to improve the overall performance and efficiency of the Dupont Printed Circuit Board.
The laminate integration can be different layers and different thicknesses. The combination of both products can make a higher intensity and powerful Dupont PCB.
What Are The Main Features Of Dupont PCB?
It is widely used in advanced technologies and applications for its variety of excellent features. It is placed on the circuit board to increase lifespan and performance efficiency.
Let’s have a look at the entire features of Dupont PCB-

They are free from Halogen. Which makes Dupont PCB more environmentally friendly. It’s a great and special feature of Dupont PCB which makes it more convenient to invent eco-friendly applications.
Halogen-Free Dupont PCB
It has Dielectric Constant property. The Dupont laminates create the platform to hold the copper traces and the circuit components. At the same time, it helps to prevent the chance of shorts between the components acting as an insulator.
These properties affect the high-frequency signal of the Dupont Printed Circuit Board. That is the Dielectric constant property of the Dupont Printed Circuit Board.
Coefficient Of Thermal Expansion(CTE)
Another crucial feature of the Dupont Printed Circuit Board is the Coefficient of Thermal Expansion. It’s an essential step during the thermal cycling step. The coefficient of Thermal Expansion is the amount of contraction of the PCB board that goes along with the temperature change.
While choosing the laminates, it should have a low CTE and also must match the copper layer’s CTE.
What Are The Advantages Of Dupont PCB?
Dupont PCBs have many advantages so they are used in the fabrication of electronic applications. Dupont PCB can construct more small, flat, and simple devices. That makes our life more simple and smooth.

Complex Repair and update
The Dupont laminating process on the PCB is quite complex. Initially, it can be customized. In case of any damage, repairing and updating the circuit is not easy at all.
Hard to Recycle
Though the materials are eco-friend of Dupont PCB, it’s hard to recycle after assembly once.
What Are The Considering Factors For Choosing Dupont PCB?
Choosing the right Dupont PCB based on the application requirements isn’t rocket science. You just have knowledge about some unavoidable factors before picking a Dupont PCB.
The vital consideration factors for choosing Dupont PCB are as follows –
Before choosing a Dupont PCB, first, you should focus on the material of the Dupont PCB.
Mainly you have to be concerned about the PCB laminate manufacturing materials.
It can be made of Polyimide or copper-clad. You should choose the one according to your application’s needs.
Dupont Laminate’s Dimension
The dimension of the PDB laminate should be fit for the application. The right size of laminate will perform better in the applications.
Dupont PCB Dimension
Another important factor is the fabrication process. The fabrication process may vary from company to company. Also, it depends on the layers and prepreg stack up, the variation of applied temperature and pressure.
So far, PCBMay offers customized laminate fabrication processes for its customers.
The Dupont PCBs should have extreme weather-resistant capacity. Also, it has the working ability in different stress situations. Both can ensure a high-performance Printed Circuit Board.
Reliability And Durability
Last but not least, the noteworthy factors are the reliability and the durability of the Dupont PCB. You must choose the durable as well as reliable Dupont Printed Circuit Board. The overall health and performance of electrical devices depend on the durability of Dupont PCB laminates.
What Is The Lamination Process Of Dupont PCB?
Dupont Printed Circuit Board has a layer of Dupont laminates. Which is fabricated by the general Dupont lamination process across solder mask, substrate, and silkscreen. This process has the following steps-
- First, wash the PCB panels. The corrosion, dry film stripping, dry film, anti-foam residues, and even fingerprints are removed in this washing process.
- Next, perform the Micro-etching method. The standardized brown or black oxide treatment is done in this process. The Micro-etching process will decrease the copper thickness.
- Then use epoxy resin which provides better adhesion on the Printed Circuit Board. It also works against problems like delamination.
PCB Epoxy Resin
- In the gluing machine, the inner layers of PCB and prepreg are stacked and then glued together.
- Once glued, the inner layers are connected with the prepreg. Again, rivets are used to complete registration and increase the strength of the Dupont PCB. This strength of inner layers and prepreg which are stack-up will not move during the lamination process.
- The stack-up layers and prepreg are subjected to high pressure and temperature. Where pressure can be over 180 tons/square meter. Again, the temperature is applied based on the PCB materials and datasheet. Usually, 365 degrees Fahrenheit is the ideal temperature for Dupont Printed Circuit Board laminate fabrication.
- After going through high temperatures and pressure, the layers are kept in a cold press system. Then placed under an X-ray machine to unmold them.
- Finally, panels are established to complete the Dupont lamination process on the Dupont Printed Circuit Board.
