How are aluminum substrates made?

Manufacturing process of aluminum PCB with HASL surface finish: Cutting → Drilling → Circuit → Acid/Alkali Etching → Solder Mask → Silk Screen → HASL → V Cut → PCB Test → FQC → FQA → Packing → Delivery. PCBHERO can provide aluminum core PCBs with the same surface treatment processes (Immersion Gold/Thin/Silver, OSP, etc.) as FR-4 PCBs.

What element destroys aluminum?

Gallium
Small amounts of gallium will destroy anything made of aluminum, including aluminum cans. It also attacks steel and makes it very brittle. It may melt in your hands, but it will not boil unless heated to 4,000 degrees Fahrenheit, the highest range of any element.

What are the three disadvantages of aluminum?

Aluminum has the following disadvantages:
Corrosion: Aluminum is susceptible to corrosion, which can lead to structural damage and failure.
Softness: Compared to other metals, aluminum is relatively soft and can be easily scratched and dented.
Conductivity: Aluminum is a good conductor of heat and electricity.

What materials are similar to FR4?

CEM-1 material is a combination of paper, glass fabric epoxy, and phenolic compounds and is suitable for single-sided PCBs. Offers similar dielectric properties to FR4 within a lower budget. CEM-2 material exhibits a higher glass transition temperature compared to CEM-1 material.

Is aluminum suitable for keyboard plates?

Aluminum is considered a middle ground, offering some flexibility while maintaining a slightly higher pitched, more pronounced bottom-out sound. The Candybar Premium Keyboard has three plate material options: aluminum (shown here in four colors), carbon fiber, and polycarbonate. August 21, 2023

Is it okay to wash the PCB with water?

For many circuit board contaminants, compressed air alone can remove dry contaminants such as dirt and dust. If the stain is stubborn, you can use distilled water and a soft brush or a cleaner such as baking soda to remove the stain without damaging the board itself.pcblink

What is the difference between FR4 and polyimide?

Durability: Although FR4 is strong, its stiffness can pose problems in applications where vibration or heat is a concern. Heat and physical stress reduce the structural integrity of FR4 boards, but polyimide boards have the ability to handle such conditions, especially thanks to their flexibility and tensile strength.

Why is FR4 used for antennas?

FR4 and Roger substrates were used due to their ease of manufacturing. The proposed antenna can operate in three frequency bands ranging from 10 to 40 GHz. A partial ground plane approach is used to increase antenna return loss and bandwidth.
