COVID-19 IMPACT

Bonding Wires Industry Had a Negative Effect Due to Supply Chain Disruption During COVID-19 Pandemic

The global COVID-19 pandemic came in a fashion that was unprecedented and remarkable; however, the market has experienced lower-than-expected demand on every continent when benchmarked to pre-pandemic rates. The asymmetric growth in CAGR is due to the growth and demand of the market returning towards pre-pandemic levels.

The pandemic had a massive impact on supply chains, particularly in semiconductor and electronics. Supply chain disruptions regarding manufacturing and the decrease of factory operations had a large impact on the production of integrated circuits, which dampened the demand for bonding wires in the short run. When demand headed back toward pre-pandemic numbers, consumer electronics, medical devices, and automotive sectors saw demand revive with the rise in digitalization experienced post-pandemic. The rise in work-from-home setups was a significant contributor to the growth in laptops, smartphones, and routers, all of which have integrated circuits and ICM components made with bonding wires.

LATEST TREND

Shift Toward Fine-Pitch Bonding and Microelectronics Applications

The increasing use of fine-pitch bonding wires for advanced packaging in high-density ICs is driving this sector of the market. As chips shrink and chip power increases, micro-bonding capability is increasingly necessary. Advanced bonding materials that are available today (such as silver alloys, palladium-coated copper, ultra-thin gold wires) improve electrical conductivity, reduce bonding resistance, and provide corrosion resistance, among other properties. Most of these developments in wire bonding technology exist to complement and enable the high-speed data transfer taking place in many applications, especially for 5G infrastructure and automotive radar. In addition, hybrid bonding (the combination of wire bonding technology with flip-chip technology) is becoming a growth area to address the size and performance limitations of measuring size of modern electronics.

BONDING WIRES MARKET SEGMENTATION

BY TYPE

• Gold Bonding Wires: Historically gold has been the dominant choice for bonding wire materials. Gold wires have established reliability and superior bond stability. Because of the high and fluctuating cost of gold, substitution has occurred in high-volume use scenarios; yet gold will remain a material of choice for mission-critical types of applications, as in aerospace electronics and avionics, and defence and military applications.

• Copper Bonding Wires: Copper has emerged to provide the cost-effective alternative to gold and copper is appreciated for its excellent electrical conductivity. Copper is widely used as bonding wire in and for IC Memory Devices, LEDs, and automotive electronics. Bonding copper wire also requires advanced surface treatment to protect the wires from oxidation.

• Silver Bonding Wires: Silver is gaining traction and is recognized for its high conductivity and resistance to oxidation and is used in power electronics and RF devices; although, still primarily in niche applications, it is anticipated that use of silver will grow in certain low-resistance applications.

• Aluminium Bonding Wires: Used quite commonly for power devices, and discrete components, aluminium is widely available, cheap, mechanically useful, and has good thermal conductivity making it especially appropriate for high-current applications.

BY APPLICATION

• Integrated Circuits (ICs): The largest segment of the bonding wire segment with bonding wires interconnecting chip pads to lead frames or substrates. It is the most critical bonding wire applications for memory, logic, and analog chips.

• Transistors: Power transistors and RF transistors rely on bonding wires to maintain stable current transfer in high temperature environments.

• Diodes: Use implantable signal and power diodes where reliable interconnections are vitally important for device stability.

• Others: Includes applications with sensors, MEMs devices, and LED packages.

MARKET DYNAMICS

DRIVING FACTORS

High Growth in Semiconductor Demand Across Industries

The continued proliferation of semiconductor information technology in consumer electronics, automotive vehicles, and IoT devices fuels the demand for bonding wires. Shortly to become mainstream, advanced technologies such as AI, 5G, and autonomous vehicles necessitate vast quantities of advanced microchips, thereby contributing to a significantly increased demand for bonding wire in packaging and interconnect applications.

Emerging Technologies Focused on Wire Materials and Bonding Technologies

Continuous advancements in wire materials such as Pd coated copper and Ag-alloys offer enhanced performance with natural high-frequency and high-temperature performance advantages. Characteristically, significant developments in bonding techniques, particularly ultrasonic and thermosonic bonding, match well with these materials and support continued wiring and packaging module miniaturization that will not sacrifice reliability.

RESTRAINING FACTORS

Raw Material Pricing Volatility

The impact of raw material fluctuations, particularly with respect to manufacturing metals, specifically gold, silver, and copper, can significantly affect manufacturing cost structures and profits. OEMs must manage the challenge of gold costs and decisions about whether to pursue other alternatives that drive costs lower but diminish reliability in high-reliability applications.

OPPORTUNITY

Growth in Electric Vehicles (EVs) and Electronics in Automobiles

The transition to EVs and the increase in electronic content per vehicle has created an additional outlet for bonding wires, especially for power module and battery management systems. Considering heat and vibration characteristics along with the need for long- term performance in small package size electronics, wire bonding provides reliable interconnections.

CHALLENGE

Miniaturization and Thermal Management in Advanced Chips

The trend for smaller and faster chips makes it more difficult to bond the chip, as ultra-fine wires and tight tolerances will be required. When wiring the part, thermal stress and the reliability of the bond are a major concern, particularly as the wire loops get tighter and the bonding pads shrink in size.
