A smart door lock is an advanced version of traditional mechanical locks, designed to enhance user safety, identification, and management. These locks are key components in access control systems. There are four types of printed circuit boards (PCBs) used in smart door locks: internal items, external items, switch items, and antenna housings. All of these PCBs are made from FR-4 material and feature a lead-free spray tin surface treatment, a green solder mask, and white silk screen printing. The internal PCB is a four-layer board with blind holes and measures 150mm by 180mm. The external PCBs are similar in size and shape but do not have blind holes.

For the internal printed circuit boards, in addition to assembling the necessary components, springs, coils, and flat components must also be soldered in. This process involves both horizontal welding and angle protection. Once all four types of PCBs have their components assembled, they must be connected with wires. Three types of wires are used: two-needle, three-needle, and ten-needle. Each wire is color-coded to help customers easily identify the ends of the same wire.

To secure the wires, heat shrink tubing is applied over them. It is important to maintain the same distance between the ends of each wire, and the tightness of the heat shrinkable tubing must be just right: if it is too tight, it may damage the wires, while if it is too loose, it will not secure the wires effectively. Finally, the four types of PCBs are connected using the finished wires.
