What is Cu clip package? copper pipes

Power chips are linked to exterior circuits via packaging, and their efficiency depends on the assistance of the product packaging. In high-power circumstances, power chips are generally packaged as power components. Chip affiliation refers to the electric link on the top surface of the chip, which is normally light weight aluminum bonding cable in traditional components. ^
Typical power component bundle cross-section

Currently, commercial silicon carbide power components still primarily use the product packaging innovation of this wire-bonded conventional silicon IGBT module. They encounter troubles such as huge high-frequency parasitic specifications, insufficient heat dissipation capacity, low-temperature resistance, and not enough insulation toughness, which restrict using silicon carbide semiconductors. The screen of superb efficiency. In order to address these troubles and fully manipulate the massive potential benefits of silicon carbide chips, numerous new product packaging modern technologies and services for silicon carbide power components have arised in the last few years.

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

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

1. The link between the chip and the pins is made from copper sheets, which, to a specific extent, replaces the common cord bonding method in between the chip and the pins. As a result, an unique bundle resistance value, greater current flow, and far better thermal conductivity can be acquired.

2. The lead pin welding area does not need to be silver-plated, which can fully conserve the expense of silver plating and poor silver plating.

3. The item appearance is totally consistent with typical products and is primarily used in web servers, mobile computer systems, batteries/drives, graphics cards, motors, power materials, and various other fields.

Cu Clip has two bonding techniques.

All copper sheet bonding technique

Both the Gate pad and the Resource pad are clip-based. This bonding technique is a lot more pricey and complicated, yet it can attain much better Rdson and better thermal results.

Copper sheet plus cable bonding approach

The resource pad utilizes a Clip approach, and the Gate uses a Cord method. This bonding technique is slightly less costly than the all-copper bonding method, saving wafer area (relevant to extremely tiny gateway areas). The process is simpler than the all-copper bonding technique and can get better Rdson and far better thermal impact.
