Aluminum PCB Manufacturer
An aluminum PCB, also known as an aluminum-based printed circuit board, is a type of printed circuit board (PCB) that uses an aluminum base material instead of the traditional FR-4 glass fiber-reinforced epoxy resin. Aluminum PCBs are typically used in applications where high thermal conductivity and/or electromagnetic interference (EMI) shielding is required.
Aluminum PCB Manufacturing Solutions
Aluminum PCBs are printed Circuit Boards which contain a thin layer of conductive dielectric material. They are also known as Aluminum Clad, Aluminum base, MCPCB (Metal Clad Printed Circuit Board), IMS (Insulated Metal Substrate), Thermally Conductive PCBs etc.The aluminum base material of an aluminum PCB is a good conductor of heat, which makes it effective at dissipating heat generated by electronic components. This can be particularly useful in applications where the PCB is subjected to high temperatures or high power densities, such as in LED lighting and power electronics. Aluminum PCBs can also be used in applications where EMI shielding is required, as the aluminum base material can effectively block the transmission of electromagnetic radiation.

Testing Procedures
There are several advantages to using aluminum PCBs (printed circuit boards) in electronic devices and systems. Some of the main benefits include:
One of the main advantages of aluminum PCBs is their ability to dissipate heat effectively, which can improve the performance and lifespan of electronic components. They are also more durable and have a longer lifespan compared to traditional PCBs, as they are not prone to warping or delamination. However, they are generally more expensive to manufacture than traditional PCBs, as the production process is more complex.
There are several advantages to using aluminum PCBs (printed circuit boards) in electronic devices and systems. Some of the main benefits include:
- Thermal management: Aluminum is a good heat conductor, so aluminum PCBs can effectively dissipate heat from electronic components, which can improve their performance and extend their lifespan.
- Weight reduction: Aluminum is lighter than traditional PCB materials, such as FR-4, which can help reduce the overall weight of electronic devices and systems.
- Durability: Aluminum PCBs are more resistant to physical damage and environmental factors, such as moisture and corrosion, than traditional PCB materials. This makes them suitable for use in rugged or harsh environments.
- Cost effectiveness: Aluminum PCBs can be more cost-effective than traditional PCB materials in some cases, especially for high-volume production runs.
- Electromagnetic interference (EMI) shielding: Aluminum PCBs can be used to effectively shield electronic components from EMI, which can improve the reliability and performance of electronic devices and systems.
aluminum PCBs offer a combination of performance, durability, and cost-effectiveness that make them a good choice for many electronic applications.

The received assembled PCB's worked flawlessly. The placement of the parts is excellent. I had a very good contact with Mis wang the WINOW engineer who took care of our project. She asked the right questions to make sure the project was finished correctly. We had a very pleasant communication, fast and to the point.
This board is needed to charge the lipo batteries of my robotic platform (rover). First time order with excellent communications throughout the ordering, manufacturing progress and up to delivery tracking. Very good price especially the first order with a discount credit.
Boards arrived yesterday and got started on assembly. Excellent, solder wetting, clean line
definition, via drill holes exactly in the middle of via lands.
Please pass my thanks back to one and all who made such excellent boards.
