1.1 Core-Shell Framework and Bonding Mechanism

(Copper-Coated Steel Fibers)

Copper-coated steel fibers (CCSF) are composite filaments including a high-strength steel core enveloped by a conductive copper layer, creating a metallurgically adhered core-shell architecture.

The steel core, usually low-carbon or stainless-steel, provides mechanical robustness with tensile staminas surpassing 2000 MPa, while the copper layer– normally 2– 10% of the total diameter– imparts exceptional electrical and thermal conductivity.

The user interface between steel and copper is vital for performance; it is engineered via electroplating, electroless deposition, or cladding procedures to make certain solid adhesion and very little interdiffusion under functional stresses.

Electroplating is the most common technique, using accurate thickness control and uniform coverage on constant steel filaments drawn with copper sulfate bathrooms.

Proper surface area pretreatment of the steel, including cleaning, pickling, and activation, makes sure optimum nucleation and bonding of copper crystals, protecting against delamination throughout subsequent processing or service.

In time and at raised temperatures, interdiffusion can develop brittle iron-copper intermetallic phases at the interface, which might compromise adaptability and long-term integrity– an obstacle alleviated by diffusion barriers or fast handling.

1.2 Physical and Functional Characteristic

CCSFs combine the best attributes of both basic steels: the high elastic modulus and fatigue resistance of steel with the remarkable conductivity and oxidation resistance of copper.

Electric conductivity normally varies from 15% to 40% of International Annealed Copper Requirement (IACS), relying on finish thickness and purity, making CCSF significantly more conductive than pure steel fibers (

Currently, industrial silicon carbide power modules still mainly utilize the packaging innovation of this wire-bonded standard silicon IGBT module. They encounter issues such as large high-frequency parasitic specifications, not enough warm dissipation capacity, low-temperature resistance, and not enough insulation toughness, which restrict the use of silicon carbide semiconductors. The display screen of outstanding performance. In order to resolve these issues and completely exploit the substantial prospective benefits of silicon carbide chips, many new packaging innovations and remedies for silicon carbide power modules have emerged over the last few years.

Silicon carbide power component bonding technique

(Figure (a) Wire bonding and (b) Cu Clip power module structure diagram (left) copper wire and (right) copper strip connection process)

Bonding products have developed from gold wire bonding in 2001 to aluminum wire (tape) bonding in 2006, copper cable bonding in 2011, and Cu Clip bonding in 2016. Low-power tools have actually developed from gold wires to copper cables, and the driving force is expense decrease; high-power devices have actually created from aluminum wires (strips) to Cu Clips, and the driving force is to enhance product efficiency. The better the power, the greater the requirements.

Cu Clip is copper strip, copper sheet. Clip Bond, or strip bonding, is a product packaging procedure that uses a strong copper bridge soldered to solder to link chips and pins. Compared with traditional bonding product packaging techniques, Cu Clip technology has the following advantages:

1. The link between the chip and the pins is constructed from copper sheets, which, to a specific degree, changes the common cord bonding technique between the chip and the pins. Consequently, a special bundle resistance value, higher present circulation, and far better thermal conductivity can be obtained.

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

3. The item appearance is completely regular with regular products and is generally made use of in servers, portable computer systems, batteries/drives, graphics cards, motors, power supplies, and other fields.

Cu Clip has two bonding approaches.

All copper sheet bonding technique

Both eviction pad and the Source pad are clip-based. This bonding method is a lot more pricey and intricate, but it can accomplish far better Rdson and much better thermal effects.

Copper sheet plus cord bonding method

The resource pad makes use of a Clip technique, and eviction utilizes a Wire technique. This bonding approach is a little cheaper than the all-copper bonding method, conserving wafer location (suitable to really small gate locations). The procedure is simpler than the all-copper bonding technique and can obtain much better Rdson and much better thermal effect.
