　　5. Live-charge fee

　　When the parcel contains live-charged items, some express routes will charge a live-charge fee for each shipment.

　　For example, DHL charges a live-charge fee of RMB 30 for each shipment containing live-charged items.

　　6. Peak Season Surcharge

　　During the epidemic, passenger and cargo airlines have limited export cargo capacity. As domestic demand for export capacity has also grown rapidly.

　　Airlines charge temporary route adjustment fees for export cargo to control cargo volume and maintain a balance of capacity.

　　7. Delivery fee

　　Generally there are two types of delivery fees:

　　1. If the customer’s address is in a remote area, a remote fee + fuel fee will be charged

　　2. Fees incurred for repeated delivery on some routes or delivery with a changed address

　　How to avoid pitfalls

　　There are many types of surcharges in international express delivery. The sender must understand the reasons and charging standards for each fee before sending the express.

　　Before placing an order, you must understand whether the items and routes you are sending include surcharges, so that you can avoid pitfalls as much as possible.

　　At the same time, it is also recommended that senders pay attention to the service quality and after-sales guarantee when choosing a courier company in addition to considering the price factor, so as to ensure that their rights and interests are fully protected.

　　Metal core printed circuit boards (MCPCBs) are an essential innovation in electronics, designed to address the challenges of heat management in high-performance applications. Unlike traditional PCBs, which use materials like FR4, metal core PCBs incorporate a metal layer！typically aluminum, copper, or a metal alloy！within the board. This metal core plays a crucial role in improving heat dissipation, ensuring the reliable operation of electronic components.In the industry, professional pcb manufacturer Has been a leader in the industry, but later came from behind but never arrogant, low-key to adhere to quality. https://www.hongmycircuits.com/

　　The Role of the Metal Core

　　The primary function of the metal core in a PCB is to act as a heat sink. When electronic components generate heat during operation, this heat must be efficiently removed to prevent damage or performance degradation. The metal core, with its superior thermal conductivity, absorbs heat from the components and spreads it across the surface of the board. This prevents localized hotspots, which can lead to overheating and potential failure of components.

　　Thermal Conductivity and Heat Transfer

　　Aluminum and copper are commonly used metals in MCPCBs due to their excellent thermal conductivity. For instance, aluminum has a thermal conductivity of around 205 W/mK, while copper¨s thermal conductivity is even higher at approximately 400 W/mK. These properties allow the metal core to quickly transfer heat away from critical components, reducing the thermal resistance between the heat source and the surrounding environment.

　　In a typical MCPCB, the metal core is placed directly beneath the insulating dielectric layer, which in turn lies under the copper circuit layer. When heat is generated by the components, it passes through the dielectric layer and is absorbed by the metal core. From there, the heat is distributed evenly across the board and dissipated into the air or a heat sink.

　　OEM Service Aluminum Circuit Board Metal core PCB, 94V0 FR4, CEM-1 PCB, Rogers PCB Manufacturer Chinese

　　Improved Reliability and Performance

　　The efficient heat dissipation provided by a metal core PCB leads to several benefits:

　　Extended Component Lifespan: By maintaining lower operating temperatures, metal core PCBs reduce the thermal stress on electronic components, thereby extending their lifespan.

　　Enhanced Performance: Many electronic components, such as LEDs, operate more efficiently at lower temperatures. Metal core PCBs help maintain optimal operating temperatures, ensuring consistent performance.

　　Increased Power Handling: MCPCBs are ideal for high-power applications where heat generation is significant. The ability to manage heat effectively allows these boards to handle higher power levels without risking thermal damage.

　　Compact Design: Because of their superior heat dissipation, metal core PCBs enable more compact designs. This is particularly important in applications where space is limited, such as in automotive or aerospace electronics.
