Platinized Anodes for Semiconductor Industries:-
Tiaano Platinised Titanium Anodes and Platinised Niobium anodes are most suitable for Semiconductor / electronics Industries for plating of precious metals like gold, platinum, nickel, rhodium, silver and copper. This process called electroplating. Also known as electrodeposition, this process deposits a thin layer of metal on the surface of a work piece referred to as the substrate. Semiconductors are the foundation of the electronics industry. These partially conductive products include transistors, chips and other electronic control parts, and are integral to electronic equipment from mobile phones to cars and robots.
Platinum Plating on Semiconductors:-
Platinum is an extremely rare and expensive material, even more expensive than gold. However, platinum is an exceptionally smooth-surfaced and durable material that protects against corrosion. Manufactures primarily used it as a protective coating on low-voltage, low-energy contacts.
How does plating on semiconductors using Platinized Anodes?
- ➦ The plating metal is connected to the positively charged electrode of an electrical circuit. This electrode is called the anode (Platinum Plated Titanium / Niobium Anodes)
- ➦ The work piece, or substrate, is placed at the negatively charged electrode, called the cathode.
- ➦ Both the plating metal and the substrate are immersed in an electrolytic solution called a bath.
- ➦ After submersion, a DC current is supplied to the anode (Platinum Plated Anode), oxidizing the atoms of the plating metal and dissolving them into the bath. At the cathode, the negative charge reduces the atoms, causing them to plate the substrate.
This general process describes most electroplating. However, semiconductor electroplating is much smaller in scale than the average electroplating processes. The chips in question are often less than an inch in diameter, and the circuits inside them consist of miniscule wires. Any errors, such as breakage or the addition of dust particles to the semiconductor, can result in a defective product. As a result, semiconductor electroplating involves a few extra precautions and considerations in order to ensure the quality of the finished product.
