Many friends have sent me private messages asking for a hands-on demonstration. Coincidentally, there is a smart lock project where the card reading distance is only about 3mm, and the reading distance needs to be optimized. This debugging record documents the thinking process during debugging, and comments and corrections are welcome.

How to Meet PCB Stackup Requirements

2026-05-14

In PCB design services, communicating requirements with manufacturers and suppliers is the top priority. Requests sometimes lose context because correct information is not provided, sufficient information is not listed, or no information is provided at all. Although experienced PCB designers can take steps to specify all elements they want to see in a PCB stackup, the manufacturer will ultimately make the decision, striving to balance available materials with processing capabilities and yield.
