Advantages |
Disadvantages |
| Low Cost: Aluminum is a metal that can be found in a variety of climates, so it is easy to mine and refine. Therefore, the costs of doing so are significantly lower than other metals. In turn, this means that manufacturing products with these metals are less expensive as well. | High cost. |
| Environmentally Friendly: Aluminum is non-toxic and recyclable. Manufacturing with aluminum is also conducive to conserving energy due to its ease of assembly. For printed circuit board suppliers, using this metal helps maintain the health of our planet. | The current mainstream can only do single aluminum PCB, it is difficult to do double sided aluminum PCB. |
| Heat Dissipation: High temperatures can cause severe damage to electronics, so it is wise to use a material that can help dissipate heat. Aluminum can actually transfer heat away from vital components, thus minimizing the harmful effect it could have on the circuit board. | The product will be more easily to have matter in electrical strength and pressure. |
| Higher Durability: Aluminum provides strength and durability to a product that ceramic or fiberglass bases cannot. Aluminum is a sturdy base material that can reduce accidental breakage during manufacturing, handling, and everyday use. | Aluminum is susceptible to more rapid attacks by halide ions, of which chloride (CL -) is the most frequently encountered. |
| Lightweight: For its incredible durability, aluminum is a surprisingly lightweight metal. Aluminum adds strength and resilience without adding on any additional weight. |
