The following are key considerations to keep in mind when processing RF antenna PCBs, covering all aspects from material selection to specific process requirements: 1. PCB Substrate Selection This is the most critical foundation; if the wrong material is chosen, subsequent processes cannot compensate for it. 1. Low Loss High-Frequency Materials: It is essential to … Read more
The Importance of Depth Control for Countersunk Holes A countersunk hole is a common PCB hole structure, with a larger diameter at the top and a smaller diameter at the bottom, forming a funnel-like shape. This structure is primarily used for screw fastening, allowing the screw head to be fully embedded within the PCB, preventing … Read more
Continuing from the previous article, the material combination of the stacked boards is sent into the laminator through the reflow line, thus entering the lamination process. Basic Knowledge The lamination process involves stacking copper foil, prepreg (PP), and the inner layer substrate with pre-made patterns in a specific order, and bonding them into a single … Read more
Breakthroughs in Processing Challenges of PTFE Materials for Microwave Circuit BoardsIntroductionWith the rapid development of high-frequency applications such as 5G communications, radar systems, and satellite navigation, the design and manufacturing of microwave circuit boards face higher demands. Among them, polytetrafluoroethylene (PTFE) materials have become the preferred substrate for high-frequency circuit boards due to their excellent … Read more
