Smart lock circuit board - cooperation case

Speaking of smart locks, I believe that everyone is no longer unfamiliar, and all walks of life have lost their presence on the portal. Smart locks are improved on the basis of traditional mechanical locks, they have three advantage, Such as more secure, convenient, and manageable.

we are going to introduce today is one of the PCB boards used in the smart door lock. This is the latest smart lock PCB board designed by the smart lock-manufacturer. Currently still in the proofing and testing section.

Design parameter:

Single panel, physical pins 3000 Pin,density higher than 0.05 (board size / 14 pin-components );6 layers PCB,5 layers single/power(Including surface layer),1 layer GND.

 

Design difficulty:

Dual-mode phone,including two groups baseband circuit,two groups SIM card circuit and other  peripheral circuit,Layout routing is very difficult,Mixed interleaving of various digital analog signals. It is necessary to ensure the quality of all kinds of digital analog signals as well as the distribution of all networks. The structure size and the number of design layers are limited. There is no compromise expansion space. The layout and wiring density is high, and the design is difficult.

 

Solution:  our technician evaluated the customer's requirements, it has achieved the structure size required by the customer. In the case of interleaving of various digital and analog signals, it adopts the processing measures of all analog signals including ground processing, avoiding the high-speed digital signals of the adjacent layer, and maintaining the integrity of the ground plane of the reference layer, so as to ensure the signal quality. The products are delivered to the customers according to the scheduled time limit, which is affirmed by the customers.
