With the rapid development of consumer electronics, the size of chargers is becoming smaller and the power is increasing. From 18W to 65W, and now to the common 100W or even 240W PD fast charging, while chargers continue to break through their limits, they also bring a serious challenge – heat dissipation.
If the heat cannot be exported in a timely manner, key components such as MOS tubes, transformers, inductors, capacitors, etc. inside the charger will face high temperature pressure, resulting in:
life shortening
Reduced efficiency
Increased safety hazards
Therefore, the selection of thermal management materials has become a key factor in the reliability of consumer electronic chargers.
Customer pain points and challenges
Customer requirements:
High heat generation under high power density
The charger is compact in size and tightly stacked internally, making it difficult to quickly dissipate heat.
Materials that balance thermal conductivity and flame retardancy
Require UL94 V-0 flame retardant and 2.0 W/mK thermal conductivity.
Complex assembly process
Traditional thermal conductive silicone grease is prone to splashing, and thermal conductive sheets have problems such as poor adhesion and excessive stress, which affect production efficiency and product consistency.
Cost sensitive
The consumer electronics industry is fiercely competitive, and customers need to balance performance and cost to avoid excessive increase in BOM costs.
