Board Level Heatsinks

The surface-mount heat sinks is suitable for SMT power semiconductor devices in TO 252, TO 263 packages, etc. Their unique design removes heat indirectly through conduction without making contact with the SMT device like traditional through-hole solutions.

A heat sink is a heat exchanger that enables the transfer of heat generated by a device to surrounding media of lower temperature. By dissipating heat away from the device, its main function is to balance said device’s temperature at optimum levels for it to function as desired. The satmping heatsinks provide for tight integration of the heat sinks, minimize product cost, and enable fast ramp-up to high-volume production.

For power devices like power MOSFET, power BJT and power diode, heat sink is very important to provide heat dissipation. From the name itself, it will absorb the heat of the power device and help control the temperature of the safe zone inside the device.

In various types of switching power supplies, MOS transistors, as key power switching devices, generate a lot of heat when working. MOS heat sinks can ensure that MOS tubes work within a stable temperature range and improve the efficiency and reliability of power supplies.

Aluminum heatsink can effectively transfer the heat generated by TO-220 components to the surface of the heat sink and then dissipate it into the surrounding environment. Compared with some other metal materials, aluminum is relatively low in cost and light in weight, making it suitable for widespread use in electronic devices.

In various power amplifier circuits and power supply circuits, TO-220 packaged power transistors, three-terminal regulators and other components will generate a lot of heat when working. The use of aluminum heat sinks can effectively reduce the temperature of components and ensure the normal operation and stability of the circuit.

Common TO - 220 aluminum heat sinks have flat plate and fin types. Fin type has multiple fins to increase area and efficiency. Flat plate is simple for low - space and small - heat - dissipation cases. The heat sink has mounting holes or slots for fixing TO - 220 components to improve heat transfer.

TO-220 packages are used for high-powered components with 0.1 inch pin spacing and have a metal tab with a hole for mounting to a heatsink. A TO-220 heatsink is used to help dissipate heat from TO-220 packaged chips, such as transistors and regulators, to improve their performance and extend their life.

Nowadays, the inverter power supply is developing towards high power, high reliability, and miniaturization. This leads to a continuous increase in power density. The high temperature from high power density affects most electronic components, causing failures. Thus, thermal design is crucial in inverter design.

Thermal problems are a main reason for electronics failures. A high ambient temperature can greatly shorten the lifespan of electronics. With the rising heat dissipation from microelectronic and high - frequency devices such as IGBT and MOSFET, less space is available for heat dissipation. The Heatsinks to enhance heat dissipation in switch power supplies is very important.
