Whatare the characteristics and applications of aluminum substrate?
Of all themetal core PCBs commonly used in smt placement factories, aluminum core PCBsare the most common type. The substrate consists of an aluminum core andstandard FR4. It has a thermal overlay for efficient heat dissipation whilecooling the component and improving the overall performance of the product. Itis currently considered as a solution for high power and tight toleranceapplications.
Advantages of aluminum substrate
1.Environmentally friendly: Aluminum is non-toxic and recyclable. The use ofaluminum manufacturing is also beneficial to save energy because it is easy toassemble. For smt SMD factory, the use of this metal helps to maintain thehealth of our planet.
2.heat dissipation: high temperature can cause serious damage to electronicproducts, so it is wise to use materials that help dissipate heat. Aluminum canactually transfer heat away from important components, thus minimizing theharmful effects it may have on the board.
3.Higher durability: Aluminum provides products with strength and durability thatceramic or fiberglass bases cannot provide. Aluminum is a strong base material,smt patch manufacturer can reduce accidental breakage during manufacturing,handling and daily use.
4.lightweight: smt patch in due to its incredible durability, aluminum is asurprisingly lightweight metal. Aluminum adds strength and flexibility withoutadding any additional weight.
Applicationsof aluminum substrate
1,audio equipment: input and output amplifiers, balanced amplifiers, audio amplifiers,preamplifiers, power amplifiers.
2、Power supply: switching regulator, DC/AC converter, SW regulator,etc.
3、Communication electronic equipment: high frequency amplifier,filtering appliance, transmitting circuit
4、Office automation equipment: motor drive, etc.
5、Automotive: electronic regulator, ignition, power controller, etc.
6、Computer: CPU board, floppy disk drive, power supply equipment, etc.
7、Power module: inverter, solid state relay, rectifier bridge
8,lamps and lighting: as the advocate of energy-saving lamps, a variety ofcolorful energy-saving LED lamps are popular in the market, and aluminum pcbfor LED lamps are beginning to be used on a large scale.
Storage conditions
AluminumPCBs are usually stored in a dark, dry environment. Most aluminum PCBs aresusceptible to moisture, yellowing and blackening. They should generally beused within 48 hours after opening the vacuum package.
