The underlying logic is that high-end computing will become a scarce future resource, and only those who build their own supply chains will survive. However, the market has reacted strongly—every company announcing huge spending has seen its stock price drop immediately, with higher investments correlating to steeper declines.

This is not just a problem for companies without a clear AI strategy (like Meta). Even firms with mature cloud businesses and clear monetization paths, such as Microsoft and Amazon, are facing pressure. Expenditures reaching hundreds of billions of dollars are testing investor patience.

While Wall Street’s nervousness may not alter the tech giants’ strategic direction, they will increasingly need to downplay the true cost of their AI ambitions. Behind this computing power contest lies the ultimate between technological innovation and capital’s patience.

Roger Luo said:The current AI computing power race has transcended mere technology, evolving into a capital-intensive strategic game. While giants are betting that computing power equals dominance, they must guard against the potential pitfalls of heavy-asset models—capital efficiency traps and innovation stagnation.

Currently, commercial silicon carbide power components still mostly utilize the product packaging modern technology of this wire-bonded typical silicon IGBT component. They face troubles such as huge high-frequency parasitical specifications, not enough heat dissipation capability, low-temperature resistance, and inadequate insulation stamina, which restrict using silicon carbide semiconductors. The display screen of outstanding efficiency. In order to resolve these troubles and totally manipulate the significant possible advantages of silicon carbide chips, numerous new product packaging modern technologies and remedies for silicon carbide power modules have emerged over the last few years.

Silicon carbide power component bonding method

Bonding materials have actually created from gold wire bonding in 2001 to light weight aluminum wire (tape) bonding in 2006, copper wire bonding in 2011, and Cu Clip bonding in 2016. Low-power tools have actually created from gold cables to copper cords, and the driving force is expense reduction; high-power tools have actually established from light weight aluminum cords (strips) to Cu Clips, and the driving pressure is to enhance item performance. The greater the power, the greater the needs.

Cu Clip is copper strip, copper sheet. Clip Bond, or strip bonding, is a product packaging procedure that utilizes a strong copper bridge soldered to solder to link chips and pins. Compared to typical bonding packaging techniques, Cu Clip innovation has the following benefits:

1. The connection in between the chip and the pins is constructed from copper sheets, which, to a specific extent, changes the basic cable bonding method between the chip and the pins. For that reason, an unique bundle resistance worth, higher existing flow, and far better thermal conductivity can be gotten.

2. The lead pin welding area does not need to be silver-plated, which can completely save the expense of silver plating and inadequate silver plating.

3. The product look is completely consistent with regular products and is generally utilized in web servers, portable computer systems, batteries/drives, graphics cards, electric motors, power products, and various other fields.

Cu Clip has 2 bonding techniques.

All copper sheet bonding technique

Both eviction pad and the Source pad are clip-based. This bonding technique is extra costly and complex, yet it can achieve much better Rdson and much better thermal impacts.
