What is Cu clip package? copper per ounce


Power chips are linked to outside circuits with product packaging, and their performance depends on the support of the product packaging. In high-power situations, power chips are typically packaged as power components. Chip interconnection describes the electrical link on the top surface area of the chip, which is generally aluminum bonding wire in standard components. ^

At present, industrial silicon carbide power components still primarily make use of the packaging modern technology of this wire-bonded standard silicon IGBT component. They face issues such as big high-frequency parasitic criteria, inadequate warmth dissipation capability, low-temperature resistance, and insufficient insulation toughness, which restrict making use of silicon carbide semiconductors. The display screen of exceptional performance. In order to resolve these troubles and completely make use of the big potential benefits of silicon carbide chips, many new packaging innovations and services for silicon carbide power components have emerged recently.

Bonding products have created from gold cord bonding in 2001 to light weight aluminum cord (tape) bonding in 2006, copper cord bonding in 2011, and Cu Clip bonding in 2016. Low-power tools have actually developed from gold cords to copper wires, and the driving force is price reduction; high-power tools have actually developed from aluminum wires (strips) to Cu Clips, and the driving force is to boost item efficiency. The higher the power, the greater the requirements.

Cu Clip is copper strip, copper sheet. Clip Bond, or strip bonding, is a product packaging procedure that makes use of a strong copper bridge soldered to solder to attach chips and pins. Compared to traditional bonding product packaging approaches, Cu Clip technology has the following advantages:

1. The connection in between the chip and the pins is constructed from copper sheets, which, to a particular level, replaces the typical cable bonding technique between the chip and the pins. Therefore, a special plan resistance worth, higher present flow, and far better thermal conductivity can be obtained.

2. The lead pin welding location does not require to be silver-plated, which can totally conserve the expense of silver plating and poor silver plating.

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

Cu Clip has 2 bonding methods.

All copper sheet bonding method

Both the Gate pad and the Source pad are clip-based. This bonding technique is much more costly and complicated, yet it can accomplish much better Rdson and much better thermal results.

Copper sheet plus cord bonding technique

The resource pad utilizes a Clip approach, and the Gate makes use of a Cord approach. This bonding method is somewhat cheaper than the all-copper bonding approach, conserving wafer area (appropriate to really small gateway locations). The procedure is less complex than the all-copper bonding method and can obtain much better Rdson and much better thermal result.
