5 FAQs of 140× 190mm 0.38mm 0.5mm 0.635mm Thick Aluminum Nitride Ceramic Plate Aln Substrate

What makes aluminum nitride plates special?
Aluminum nitride plates move heat very well. They beat most other ceramics here. This keeps electronics cool and reliable. They also insulate electricity perfectly. You get both top heat transfer and electrical safety in one material.

Where do people use these plates?
These plates go into things needing serious heat control. Think high-power LED lights. Think power modules for electric cars and trains. They’re also vital in semiconductor tools. They manage heat in tight spaces where metals fail.

Why offer different thicknesses like 0.38mm, 0.5mm, and 0.635mm?
Thickness impacts performance. Thinner plates move heat slightly faster. They also fit into smaller devices. Thicker plates are stronger mechanically. They resist bending and cracking better under stress. Pick the thickness matching your need for heat flow, space, and durability.

Can these plates handle high temperatures?
Yes. Aluminum nitride laughs at heat. It works perfectly fine well over 1000°C. This makes it ideal for furnaces, aerospace sensors, and other extreme heat environments. It won’t melt or weaken like plastics or even some metals.

Are these plates fragile like regular ceramics?
Aluminum nitride is very hard. This hardness resists scratches and wear. But it is still a ceramic. It can crack if hit very hard or bent too much. Handle it carefully during assembly. Once mounted securely, it performs reliably for years. Its toughness is good for demanding industrial jobs.
