In the process of making high-quality mixed-pressure high-frequency PCB, the selection of high-frequency PCB materials is undoubtedly the primary consideration. Rogers series PCB materials such as RT5880, RO3003, RO4350 and RO4003 are all high-performance high-frequency PCB materials widely recognized by the industry. However, simply choosing high-quality PCB materials is not enough to ensure the quality of the final product. The thickness of each layer of PCB materials, the PP sheets used, and the overall stacking thickness all need to be carefully calculated and considered.
The biggest difference of mixed-pressure high-frequency PCB is that the boards with different media are pressed together. The electrical properties of mixed-pressure high-frequency PCB are different, such as dielectric constant and loss factor. Of course, we set the goal clearly. Suppose I use the surface layer to refer to the second layer, or I can fully enjoy the performance brought by the high-speed board. However, mixed-pressure high-frequency PCB will have some difficulties in processing, mainly because the thermal properties of different boards are different, such as tg value, so that when pressing, each place will be heated slightly unevenly, which may increase the warpage. In addition, the laminated board stacking is generally not very symmetrical, which will also increase the warpage.

Multilayer circuit boards are divided into pure pressing and mixed pressing. Pure pressing means that the core boards used in the stacking are exactly the same. Mixed pressing means using different types of core boards for stacking. Pure pressing will be faster because pure pressing is to process the circuits on different layers of core boards together on the same large core board, then cut them and press them together. Mixed pressing requires different types of boards to be processed separately and then pressed together. There are fewer pure pressing processes, so the board making will be faster. Generally, pure pressing uses RF boards for pressing. Mixed pressing is sometimes a mixture of high-frequency boards and FR4 boards. FR4 boards are cheap, so sometimes the cost of mixed high-frequency PCBs is lower.
For high-frequency PCB buyers and designers, how to select high-frequency circuit board manufacturers that truly meet their needs from a lot of complex information is a test. In cooperation with iPCB, what aspects should we collect to make a wise choice?
