LED Lamp Beads Bubble

The golden line purity content of the golden lines when encapsulated LED lamp beads is more than 99.99%. The gold with such materials is produced by brushed process. In addition to the gold elements containing 99.99%, this type of gold also contains 1%as follows as follows Other trace elements. One of the components of the LED lamp beads packaging is the golden line, and the golden line is a bridge of the connected glowing chip and the welding point. How to distinguish the purity of the golden line after all? The identification of the LED gold wire can use the ICP purity detection method, the mechanical function detection method, and the EDS identity detection method to determine the purity of the LED gold wire. Use the ICP purity detection method to identify the purity level of the golden line. First, look at the outer outer outer outer of the LED lamp beads, and the first look at the appearance of the golden line should not have 5%scratch, concave pits, scratches, cracks, protrusion, discounts, and other defects that reduce the service life of the device. In the process of pulling the golden line, the appearance defects of the appearance of the silk material will cause the current density to plus the New Year's Eve, which will easily be abandoned by the damage part. At the same time. Secondly, the appearance of the golden line should be no oil pollution, rust, dust and other adhesives. These will reduce the bonding strength between the golden line and the LED lamp chip, the golden line and the bracket. Second, there is a diameter error between the dedicated golden line and the differential grid line of LED lamp beads. 1 gram of gold can pull out the gold wire with a length of 26.37m and a diameter of 50 m (2 mil). , Golden line of 25 m (1 mil) in diameter. The length of the golden line is fixed. If the diameter of the golden line is half of the original, the resistance of the measured gold thread to the end is a quarter of a quarter. For the providers of the golden line, the thinner the diameter of the golden line, the lower the cost. In the environment where the price is stable, the MM profit of LED lamp beads will be higher. For the LED lamp bead customers who use the golden wire, the golden wire that reduces the ingredients on the diameter of the purchasing diameter will exist in the harm of rising gold wire resistance and decreased fuse current. 1.0mil's golden line life must be shorter than the golden line of 1.2mil, but the simple test of the packaging factory cannot be tested. It must be used to detect the diameter of the golden line with a detailed instrument. Third, the dedicated gold wire of LED lamp beads is made of brushed from the material with a golden purity of 99.99%or more. Through a reasonable alloy component with a reasonable design, the gold silk has a tensile force and a high bond intensity, good ballistic, and vibration breaks. Low -rate strength. The Department of Alloy Silk Shipping shall be a high -purity synergy wire with a purity of more than 99.99%. The total amount of trace elements (AG/CU/Si/CA/Mg) is connected to 0.01 as follows, with the characteristics of conjunctivation of gold, and the characteristics of conjunctive gold are characterized. Make the hard -to -study function detection, that is, the detection of the tensile load loading and the extension of the golden line can be a good golden line that can be assigned when the resin packaging. At the same time, the broken force of the golden line and the extension of the extension of the quality of the leading key are related to the harmful effect. The key filament with a high break rate and the extension rate is more conducive to the key combination. Too soft golden silk will cause: vycly drooping; spherical shape; the neck of the ball is easily tightened; golden line is easy to break. Too hard golden silk will cause: Paling the chip electrode or extension; Golden ball's neck breaks; formation of alloy is hard; arched wire arcs. Use chemical identity inspection -EDS identity testing method to identify the type of material: gold, silver lines, golden bag and silver alloy lines, copper lines, aluminum lines. The golden line has long -term guidelines, good thermal conductivity, anti -corrosion resistance, good toughness, and excellent chemical invisibility, but the price of the gold thread is expensive, and the packaging cost is too high.
