Produced into hot-spot phenomenon.Relative to prior art, merely using price costly and the larger copper of quality, the above-mentioned 4th
Film layer both have good heat dissipation effect, rapidly heat can be lost in air, but with lighter weight, be easily installed casting,
The less expensive advantage of price.Meanwhile, relative to prior art, merely using the aluminium alloy that radiating effect is poor, the above-mentioned 4th
