In the LED packaging process, gold and copper wires play an important role in LED wire connection. They are responsible for connecting the electrodes on the surface of the chip with the bracket. When the wire is energized, the current enters the chip through the gold or copper wire to drive the chip to emit light. The wire quality is directly related to the performance and life of the LED display.
What is the gold wire encapsulation?
Gold wire encapsulation refers to the LED packaging process uses gold wire as a wire to connect the chip electrode and bracket technology. Gold wire is widely used in high-end LED Display due to its good conductivity and oxidation resistance.
Which LED display using gold wire encapsulation process?
Usually, if your LED displays have high-end, long life and stability requirements, it will use the gold wire encapsulation process, such as: P5, P3, P2.5, P2, P1.667 and other indoor and outdoor LED display. Such as SightLED’s P1.667 LED display:
Our P1.667 small pitch LED display using gold wire encapsulation SMD1010 lamp beads, high brush driver IC. The whole screen resolution of 360,000 points / ㎡, a single cabinet ratio of 4:3. It can be spliced into a 16:9 screen, so you can enjoy the golden ratio.
In addition, the ultra-wide LED screen viewing angle of 170 ° and the picture is uniformly clear and natural. The cabinet is lightweight, easy to install and save transportation costs. The whole cabinet is only 65mm, fashionable die-casting aluminum frame design.
All in all, Gold wire encapsulation LED display is basically used for some large outdoor LED billboards, high-end indoor LED display application.
What is copper wire encapsulation?
The opposite of the gold wire encapsulation, copper wire encapsulation uses copper wire as a conductor to connect the chip and the bracket. Copper wire encapsulation has often used because its cost is much lower than that of gold wire . With the development of technology, the copper wire encapsulation process is also progressing, and gradually overcome some technical difficulties in the early stage. However, compared with gold wire, in term of the oxidation resistance and mechanical properties, there is still a gap.
Which LED display using copper wire encapsulation process?
Copper wire encapsulation process is mostly used for low-end LED display, such as: P1.25, P1.53, P1.66, P1.86, P2.0, P2.5, P3, P4 and other indoor and outdoor LED display. Copper wire encapsulation LED display are basically used for some small indoor display, small billboards and signs etc. These LED display customer have lower budget, while the life and stability requirements are relatively low.
What is the difference between gold and copper wire in LED display?
Cost: Gold wire encapsulation LED display cost is high, mainly because the price of gold wire is expensive. Copper wire encapsulation, on the other hand, has become the preferred choice for many cost-sensitive applications due to its lower cost. The copper wire cost is usually only one-third or even less than the cost of gold wire, which has a significant cost advantage for mass LED displays.
Oxidation resistance: Gold wire has excellent oxidation resistance, which can maintain a stable connection in harsh environments. In contrast, copper wire is more susceptible to oxidization, resulting in poor connection or metal deformation, thus affecting theLED display qualification rate and service life. Therefore, in the high-end or the need for high reliability in the application, the gold wire package is more suitable.
Solder contact: Gold wire encapsulation in the solder contact is excellent, to ensure stable connection between the chip and the bracket. Due to material characteristics, the copper wire may not be easy to tightly combined with the bracket, resulting in crescent cracks or damage to the solder joints and other issues. This not only affects the quality of the secondary welding, but also may increase the risk of reliability in the process of customer use.
Thermal conductivity: Although thermal conductivity is not a direct characteristic of the encapsulated wire, but the thermal conductivity of copper wire is better than gold wire. In high-power LED applications, good thermal conductivity helps to dissipate heat quickly and improve the efficiency and stability of the LED display. However, in most LED display applications, electrical conductivity and oxidation resistance are usually more critical factors.
How to choose gold or copper wire LED display?
When choosing gold or copper wire encapsulation LED displays, it is necessary to make comprehensive considerations based on the actual application and performance requirements. For high-end applications, if you need high reliability and long life, gold wire LED display is a better choice. For lower budget or the low-end market, copper wire LED display are more attractive due to their cost advantages.
Gold wire and copper wire encapsulation LED displays each have their own unique advantages and application. With the continuous progress of technology and cost optimization, these two encapsulation technologies will continue to play an important role in LED display. In the future, with the emergence of new materials and new processes, we are expected to see more innovative LED display solution.
