What do manufacturers need to pay attention to when choosing PCB？

When selecting PCBs (Printed Circuit Boards), shared power bank manufacturers need to consider the following aspects to ensure product performance, safety, and competitiveness:

1. Durability and Reliability

   Material and Thickness: Choose high-quality PCB materials, such as FR-4, to ensure durability under high-frequency use and complex environments. Additionally, select appropriate PCB thickness according to the power and size requirements of the power bank.Component Layout: The layout of the components should be reasonable to avoid mutual interference while ensuring good heat dissipation. For components with high heat generation, such as charging management ICs and MOSFETs, adequate space for heat dissipation must be designed.

1. Charging Efficiency and Safety

   Charging Circuit Design: The charging circuit on the PCB should be designed to ensure high and stable charging efficiency. It should also integrate safety features such as overvoltage protection, overcurrent protection, and short-circuit protection to prevent device damage or accidents caused by abnormal charging.Multilayer PCB Design: Using multilayer boards can improve circuit integration, reduce wiring length, and minimize interference, thereby enhancing charging efficiency and stability.

2. Miniaturization and Portability

   Size and Weight: As competition intensifies in the shared power bank market, miniaturization and portability become key selling points. Therefore, the PCB design should be as compact as possible to reduce the overall size and weight of the power bank.Wiring Density: Increasing wiring density can further reduce the size of the PCB, but it is also necessary to ensure clarity and maintainability of the wiring.

   
   

3. Intelligence and Connectivity

   Smart Control Chips: Integrating smart control chips allows for intelligent management of the power bank, such as power display, charging status monitoring, and remote control. These functions impose higher demands on PCB design, requiring compatibility and stability between the chip and surrounding circuits.IoT Technology: With the development of the Internet of Things, more shared power banks are starting to support remote monitoring and management. Therefore, PCB design should take into account the application of IoT technologies, such as integrating wireless communication modules.

   
   

4. Cost Control and Production Efficiency

   Cost Control: While ensuring product performance and quality, reasonable control of PCB costs is an important factor for manufacturers. Costs can be reduced by optimizing the design, and choosing cost-effective materials and components.Production Efficiency: Improving production efficiency can shorten production cycles, lower production costs, and enhance market competitiveness. Therefore, PCB design should consider production efficiency and process requirements, such as simplifying process flows and increasing automation.

   
   

5. Supplier Selection

   Qualifications and Strength: Choosing PCB suppliers with the necessary qualifications and strength can ensure product quality and delivery schedules. Manufacturers should comprehensively evaluate the supplier's qualifications, production capacity, and quality control systems.Service and Support: Good after-sales service and technical support are important factors when selecting suppliers. Manufacturers should ensure that suppliers can provide timely and professional technical support and after-sales services.
