LED Package wires classification
LED Package wires are the wire electrical connection to connect these led chip to the external pins. once this wire has a problem, the LED is damaged, So as there are many different prices in the market, how many types of wires are used for led packages?
The LED Packages has 4 types of quality: gold wires, silver wires, copper wires, and alloy wires.
It is Top quality among wires in the high-end package field. it features stable performance, high price. gold is generally used to ensure a stable connection for oxidation resistance.
The alloy wires are the replacement of gold wires in the led industry. In recent years, gold prices are constantly rising, Led package wire using is also increasing. At the same time, Led product prices are reduced. therefore, cheaper alternative–alloy wire are coming out. The main component of the wire is a single crystal of silver, the content is generally 90% -99%. it consists of a lot of silver on the basis of gold and other components for a variety of elements.
1, the price is cheaper, lower than the gold price, higher than the copper price,
3, weldability is better while welding;
3, install immature in the old-fashioned wire device applications to
4, easy to oxidation.
it is better storage than copper wires, (copper wire need to be sealed, and the short life for storage; silver wire without sealing, storage of up to 6 to 12 months)Features:1, it is relatively soft, machine parameter adjustment is not large;
2, lower than the current price of gold wire, higher than copper wires.
3, no need gas protection;
4 silver wire gold wire tension is not so strong, but the light decay is better than gold silver because silver is not extinction.
1, low prices, the cost is only 1 / 3-1 / 10 of gold wires, has great potential to reduce costs.
2, relatively high stiffness copper-gold wire makes it more suitable for fine-wire bonding.
3, copper is easily oxidized, unstable bonding process,
4, copper hardness, yield strength and other physical parameters higher than gold and aluminum.
