HDI PCB Manufacturer
HDI PCB stands for High-Density Interconnect Printed Circuit Board. It is a type of printed circuit board (PCB) that is designed to have a higher component density than traditional PCBs, allowing for smaller and more complex electronic devices. HDI PCBs are manufactured using advanced techniques such as laser drilling and microvias, which allow for smaller interconnections and higher circuit densities.

Testing Procedures
HDI PCBs are used in a variety of applications, including smartphones, tablets, laptops, and other portable electronic devices. They are also used in high-speed communication systems, military and aerospace systems, and medical devices.
- Smaller size: HDI PCBs can be made smaller than traditional PCBs due to their higher component density, making them ideal for use in compact electronic devices.
- Higher performance: HDI PCBs have a lower resistance and capacitance compared to traditional PCBs, which can result in improved performance and reliability.
- Increased flexibility: HDI PCBs can be designed with flexible or rigid-flex materials, allowing for greater design flexibility and the ability to fit into tight spaces.
- Improved heat dissipation: HDI PCBs can be designed with advanced thermal management techniques, such as the use of metal core materials, to improve heat dissipation and reliability.
- Higher reliability: HDI PCBs are less prone to failure due to their advanced manufacturing processes and materials, which can result in a longer lifespan and reduced maintenance costs.
- Customization options: HDI PCBs can be customized to meet the specific needs of different applications, including the use of specialized materials and high-density features such as blind and buried vias.
- Cost-effectiveness: While HDI PCBs may be more expensive upfront, their improved performance and reliability can make them more cost-effective in the long run, particularly in applications where traditional PCBs would not be able to meet the required specifications.

How do I select an HDI PCB manufacturer?
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.
