Wear Resistance Coating for High Temperature
Wedge Bonding

Why is thermal stability important in wedge bonding and how does i-TAC® deliver it?

During ultrasonic wedge bonding, the tool faces extreme heat, friction, and vibration. Thermal instability in coatings leads to wear, oxidation, and inconsistent bonding. i-TAC® maintains surface integrity at high temperatures, ensuring stable bonding and extended tool life.

What are the performance improvements with i-TAC® compared with uncoated or conventional coatings?

Compared with uncoated tools or standard PVD and PACVD coatings, i-TAC® offers higher hardness, lower friction, and reliable performance up to 600 °C. These advantages result in longer tool life, fewer process interruptions, improved yield, and lower maintenance cost.

How does i-TAC® help reduce cost and improve yield in production?

i-TAC® minimizes tool wear and keeps friction low during bonding. This reduces downtime, cleaning frequency, and tool replacement, resulting in higher productivity, improved bonding reliability, and better overall manufacturing yield.

Which industries benefit most from i-TAC® coating?

i-TAC® is designed for industries that demand precision bonding and high reliability under thermal stress. It is widely used in semiconductor packaging, engine conponents, power electronics, and microelectronic device manufacturing where consistent bonding quality and tool longevity are critical. Its superior wear resistance and low friction make it ideal for high-volume production lines that operate under elevated temperatures.
