igbt module in the silk is silver wire, golden ferry and transparent silicone. According to the relevant information, GBT is an insulated gate bipolar transistor, which is a composite fully controlled voltage driven power semiconductor device composed of BJT(bipolar triode) and MOS(insulated gate type field effect tube). It has the advantages of high input impedance of MOSFET and low on-voltage drop of GTR.
IGBT power module is voltage type control, input impedance is large, drive power is small, control circuit is simple, switching loss is small, on-off speed is fast, high working frequency, component capacity is large and so on. The essence is a composite power device, which integrates the advantages of bipolar power transistor and power MOSFET. And because of advanced processing technology to make it pass state saturation voltage low, high switching frequency (up to 20khz), these two very significant characteristics, Siemens has recently launched low saturation voltage drop (2.2v) npt-IGBT performance is better, successively Toshiba, Fuji, ir, MOTOROLA has also been developing new varieties.
Not silver wire, but copper wire. IGBT module wire is mainly used copper wire rather than silver wire, the reason is that silver wire is expensive, and copper wire has a good balance in terms of conductivity and cost, so it is widely used.
In addition, the oxidation resistance of silver wire is not as good as that of copper wire, which is easy to produce surface oxidation layer and affect the electrical conductivity.
IGBT module is a switching device used in the field of power electronics, its main purpose is to control high-power current, complete the conversion, amplification, regulation and other functions.
In the IGBT module, the wire is a very important part, which directly affects its conductive performance and service life. Copper wire has a good balance in terms of conductivity and cost, and is a good wire material. At the same time, keeping the wire in good contact and preventing loosening can better protect the safety and reliability of the IGBT module and reduce the failure rate.
The wire inside the IGBT module is generally made of highly conductive metal materials, such as gold, silver, copper, etc.
Although sterling silver wire may be used in some high-end products, in most products, silver alloy or copper-silver alloy wire is generally used.
3 In addition to the choice of wire material itself, the cross-sectional area, length, and layout of the wire will also affect the performance and stability of the IGBT module. Therefore, various factors need to be considered comprehensively in the design and production to achieve the best results.
It is not silver because in the IGBT module, the wire is usually made of high-quality copper materials, which is because copper has excellent electrical conductivity and mechanical strength, and the price is relatively low. In addition, although silver has better electrical conductivity than copper, its price is higher and it is easy to oxidize, which will affect the performance and service life of the wire. Further extension, in addition to the selection of wire materials, the design and manufacturing of IGBT modules also need to take into account various factors, such as temperature control, material selection, component matching, etc., which will directly affect the performance and reliability of the module.
Therefore, the manufacture of IGBT modules is a complex and meticulous work that requires rigorous testing and verification before it can be put into use.
Not silver wire, but copper wire.
Because the conductive performance of silver wire is better, but the cost is higher, and the conductive ability of copper wire is also very good, and the cost is relatively low, so in the manufacture of IGBT modules, copper wire is generally used for wire production.
In addition, the length of the wire of the IGBT module will also affect its performance, and the length of the wire is generally shortened as far as possible to reduce the resistance and improve the efficiency and reliability of the module.
Normally, the wire used in IGBT modules is copper wire, not silver wire. Copper is a good conductive material and is widely used in electronic components because of its good electrical conductivity, good thermal stability, high mechanical strength, and is relatively inexpensive.

Although silver is a better conducting material, its cost is relatively high. In terms of process and manufacturing costs, silver is relatively rarely used in electronic components, and is generally only used in high-end products.

The possible use of silver wire in IGBT modules is that some manufacturers use silver wire wires to improve performance in specific products or application scenarios. But this is relatively rare and requires specific product specifications to determine.
1 Not necessarily silver.
2 The wires in the IGBT module may be made of a variety of materials, including copper, aluminum, silver, etc. Copper, aluminum and other wires have a lower cost than silver wires, but their electrical conductivity is slightly lower than silver wires, so silver wires are still used in some cases.
3 In addition, the corrosion resistance and reliability of silver wire is high, which is suitable for some occasions where the wire is strictly required.
In the manufacture of electronic components, silver wires are also commonly used for small components such as microwire connections.
It's not a silver wire. The wires in IGBT modules are usually made of materials such as copper, rather than silver.
Although silver wires are very widely used in the electronics industry, copper wires have better electrical conductivity and higher heat resistance, which can provide more stable current transmission. In the electronics industry, the choice of wire material is very important, because different materials have different physical and electrical properties. Silver wire has excellent electrical conductivity and good oxidation resistance, and is often used in high-value electronic products, such as transistors, busy roads, contacts, high-end lenses, etc. Copper wire is more common, suitable for most low-end electronic products, such as televisions, computers, mobile phones, etc. Of course, the choice of wire material for different applications will also be affected by factors such as cost, processing difficulty, and wire contact area.
It's not silver,
IGBT module inside the round wire silver wire is made of aluminum, the plate is made of pottery, by IGBT (insulated gate bipolar transistor chip) and FWD (continuous current diode chip) through a specific circuit bridge package of modular semiconductor products; The packaged IGBT module is directly applied to inverter, UPS uninterruptible power supply and other equipment.

Yes, the wire in the igbt module is silver wire.
The igbt module is covered with external components and internal components, the external components are composed of plastic shells and metal connectors, and the internal components are composed of silver wire and transparent silicone.
The internal connection wire of the imported igbt is silver.
Because the internal connection of the imported igbt needs to be changed in color, and it can be distinguished by the terminal posts, it is silver.
1 is not silver 2 Because wires are usually made with copper or aluminum, rather than silver, which conducts electricity better but costs more and is not suitable for mass production. Copper and aluminum wires are usually sufficient to meet the needs, and the cost is relatively low, and the use of silver will increase the cost of manufacturing. At the same time, the choice of material used for the wire also depends on factors such as the current and voltage it is subjected to.
On this issue, the wire inside the IGBT module is generally copper wire, because copper has good electrical and thermal conductivity, and is more economical and practical than silver. Although silver wires have better electrical conductivity, they are more expensive and are usually only used in special applications.
Not silver wire, but copper wire. Because the cost of silver wire is too high, it is not suitable for large-scale production, and copper wire has good electrical conductivity and plasticity, and can withstand high temperature and high pressure environment, so in the manufacture of IGBT modules, the use of copper wire is more common.
In the electronics manufacturing industry, copper wire is also often used in the manufacture and connection of circuit boards, integrated circuits, etc.

Silver is aluminum, not silver. It seems that the price of copper is relatively expensive recently, and it is estimated that the bad module is worth a hundred dollars according to the catty. There was also the idea of collecting IGBT waste and then extracting copper.
