LED Strip depends on the quality and attitude of manufacturers have equipment capacity. To produce high quality LED flexible strip must be to improve the management methods and reliable to do to ensure incoming inspection process, using high-precision positioning of the LED SMD placement machine, and then through the wave soldering, welding can be carried out after a good PCB test separator, connecting, testing, aging, plastic closures, aging, packaging and finished products. Step will affect every aspect of LED flexible strip performance and stability, workshop-style hand soldering and packaging out of the soft light strip is not in the anti-static workshop with precision LED SMT package with clean out high quality LED flexible strip of the same led moving light language.
One, LED lights Chip
Is a set of LED industry chain, which is in the upper reaches of the chip wafer cutting and production, which is currently the LED industry’s most technical content of a link. Epitaxial wafers mainly from Japan, Korea, Germany provided, mainland enterprises in Taiwan chip, its epitaxial wafers mainly from Japan and South Korea, the brightness, the light fades is best made in Japan, Taiwan, Guang Jia, the United States and other epitaxial Puri tablets from Japan, which provides chip reputation in the industry are better. Currently, Japan provide external epitaxial crystal factory outside except that it has to start their own cutting, which are bound to Taiwan and the mainland fab pressure. Part of the package, mainly in Taiwan and mainland China, including Taiwan enterprises in the package is a world leader appeared Everlight, Bai Hong, East Bay, a large number of high-quality corporate CMO. After the year 2000 with the blue chips and white craft after another, as well as mobile phones, backlight, lighting and other applications market expansion, ushered in the industrial packaging companies in Taiwan spring.
Second, LED light package
To encapsulate the form, from the initial line 3MM, 5MM, 8MM, 10MM, piranhas. SMD 0805,0603,1206 later development, and now the 1210 (3528), 5050, etc. TOPLED series. So LED strip is developed from the common line to 0805 and 0603,1206, and now the market is the most fiery 5050 series products. It is noteworthy that the brightness of led moving light has a direct correlation with the wafer. Currently chip package has 9MIL, 12MIL, 14MIL and other dimensions, in theory the larger wafers, higher power and brightness, of course, the price is more expensive, the current market many companies employ 5,050 package appearance, but actually using the brightness relatively low small chip, thus resulting in low prices, but the quality is not good, this is the customer irresponsible. When used to carefully identify lamp beads and brightness of the welding process, during which different instruments can be quickly identified.
Three, LED light bar package
LED light bar is divided Flexible LED strips and LED light bar two, the differences are as follows:
1, Flexible LED Strip is done using FPC circuit board assembly to be assembled with SMD LED, the thickness of the product is only a 1MM thickness, does not occupy space; common specifications per meter 30 lights, 48 lights, 60 lights, Different users have different specifications. And it can cut, it can be any extension of luminous unaffected. FPC material is soft and can be bent, folded, winding, can freely move in three-dimensional space and stretch without breaking. Suitable for irregular local and cramped places, but also because you can arbitrarily curved and winding, suitable for use in advertising in any combination of a variety of decorative patterns. FPC itself is worthy of prompt material is also a variety of points, with the formal market above is made of rolled copper dual panel FPC, of course, many enterprises are also blind pursuit of material costs down, take electrolyte made of FPC, FPC electrolyte easy to peel off during welding, Weld, and a direct result of the phenomenon of dead lights, in addition to whether it is from the electrolyte conductivity and flexibility are unable to compete with the rolled copper.
2, led moving light bar is made with hard board PCB circuit board assembly, LED SMD LED useful to be assembled, but also useful for assembly-line LED, depending on the different needs of different components. The advantage of rigid strip is relatively easy to fix, processing and installation are relatively easy; shortcomings can not be bent, not suitable for irregular areas. Rigid Strip with SMD LED per meter 30 lights, 48 lights 60 lights, a good variety of specifications; using DIP LED’s are 18, 24, 36, 48 different specifications, there is also a positive side, the side also known as the Great Wall lights glowing.
