High frequency PCB is a kind of PCB used for signal transmission in a variety of applications, including mobile, microwave, RF and high-speed design applications. High frequency boards with high frequency laminates are difficult to manufacture because they need to maintain the heat transfer of the application due to the sensitivity of the signal.

 

Manufacturing high frequency board

According to Rush PCB, all of the above laminates have individual manufacturing problems. In order to obtain the required quality and reliability, the corresponding manufacturing instructions for each material need to be followed for processing, storage, surface treatment, inner layer treatment, drilling, bonding, deburring and electroplating.

Special process is needed to make PCB with HF material. For example, preparation of plated through holes is a critical process, especially for PTFE substrates. The surface of the PTFE is specially prepared to receive the etching process. Therefore, with the correct selection of materials, following the appropriate manufacturing method is also essential for obtaining high-quality plates and working at high frequencies.
