IC Substrates manufacturer
IC substrates (also known as integrated circuit substrates or printed circuit board substrates) are specialized printed circuit boards (PCBs) that are designed to support and interconnect integrated circuits (ICs). IC substrates are used in a variety of electronic devices, including smartphones, tablets, laptops, and other portable devices, as well as in automotive, military, and aerospace applications.
Committed to Manufacturing Solutions
IC substrates are typically made using advanced manufacturing techniques and materials, such as multilayer construction, laser drilling, and microvias, to support the high-density interconnections and performance requirements of ICs. They may also be designed with advanced thermal management features, such as the use of metal core materials, to dissipate heat generated by the ICs.

Testing Procedures
There are several types of IC substrates available, including organic substrates (made from organic materials such as fiberglass), inorganic substrates (made from inorganic materials such as silicon or ceramics), and flexible substrates (made from flexible materials such as polyimide). The choice of substrate material depends on the specific requirements of the application, including the density and complexity of the ICs, the operating environment, and the required performance and reliability.
IC substrates are typically manufactured by specialized PCB manufacturers that have the capabilities and expertise to produce high-density and high-performance PCBs. To select an IC substrate manufacturer, you should consider factors such as the manufacturer’s reputation and track record in the industry, the range of substrate materials and technologies they offer, and their design and engineering support services. You should also consider the cost and lead time for the substrates, as well as the manufacturer’s quality control and testing processes.

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.
