1. Confirm the antenna plan synchronously in the early stage of the project
in the 4 g During the PCBA research and development stage, it is necessary to synchronize the structural shell and complete machine use scenarios with customers, and confirm the antenna type in advance: built-in FPC antenna, spring antenna, and rod-shaped external antenna. Selection suggestions must be given according to the product structure and use environment, and temporarily select antennas after the motherboard development is completed. This is the most common problem for many engineers, thinking that it doesn't matter to choose after it is developed!
2. The structure reserves antenna clearance to avoid metal blocking
During the structural design stage, a metal-free clearance area is reserved for the antenna, away from lithium batteries, metal brackets, and metal casings; external antenna solutions are preferred for metal casings.
3. During the prototype stage, measure the signal of the whole machine, not just the bare board
The bare board test signal is qualified ≠ the finished machine is qualified. After the prototype is installed with the shell and battery, it simulates the customer's actual use environment for networking, signal strength, and packet loss rate tests to detect problems as soon as possible.
4. Provide antenna matching debugging support
For the complete 4G PCBA solution we output, we can cooperate with customers to complete the antenna debugging and verification of the whole machine, reducing the risk of poor batch signals in later mass production.
We can also provide antenna partners to help customers better optimize and solve signal problems!
For 4G IoT products, PCBA hardware is the foundation, but antennas are the "ears and mouths" of communication products. No matter how good the 4G module and circuit board is, if the antenna is not properly matched, the communication experience of the whole machine will be greatly reduced.
Ningbo Chaojing Electronics provides one-stop services from solution research and development, PCB design, MCU software development, 4G IoT PCBA proofing to mass production. Not only outputs stable and reliable 4G PCBA, combined with more than ten years of hardware solution experience, assists customers in coordinating module, antenna, and structure coordination, reducing the risk of communication failure of the whole machine from the source, and assisting the smooth implementation of mass production of products.
