subject: Led Tube Identification With The Quality Of The 6 Points [print this page] Led Tube with the production because the threshold into the low, so many people who launched this project. But those who have experience or a way to identify, regular production of Led Tube manufacturers and cottage with a version of Led Tube with (ie within the rental depends on the products produced by manual operation) is a glance from the appearance out. Here's to our Hong Electronics Co., Ltd., Dongguan light products, for example, talk about how to identify Led Tube by eye with the quality of the good or bad:
1, see spot. With formal Led Tube Led Tube manufacturer with production is the use of SMT chip technology, solder paste and reflow process with the production. Therefore, Led Tube belt with smooth solder joints and solder volume is not more cylindrical arc-shaped solder pad from the FPC to the LED at the electrode extension. The cottage version of Led Tube solder joints with the amount of non-uniform, mostly a dot wrap welding foot, and have different levels of tin tip appeared, which is a typical phenomenon of manual welding.
2, see FPC quality. FPC copper and rolled copper sub-deposited two, Bonded Copper of copper foil is projecting, and look with the FPC, then the connection from the pad at the seen. Copper is the calendar closely, and FPC as a single entity, and can bend and will not appear any pad off phenomenon. Bonded Copper will appear if the pad bending too much off, when the temperature is too high maintenance can also cause the pad off.
3, see Led Tube with surface cleanliness. If the use of SMT technology, the Led Tube with, the surface cleanliness is very good, do not see any impurities and dirt. However, if hand-welding technology, the cottage version of Led Tube zone, no matter how clean the surface, there will be residual traces of dirt and cleaning, while the surface of the FPC will be flux residue and solder residue.
4, look at packaging. Led Tube will be a regular with paper trays with anti-static packaging, usually 5 meters a roll or a roll of 10 meters, and then use anti-static moisture out and then seal bag. The cottage version of the Led Tube with because of cost savings, while the use of recycled paper trays, and then there is no proof anti-static bags, look carefully to see the appearance of paper trays with clear labels and scratch marks left behind.
5, see label. Led Tube with regular paper trays bags and above will have a printed label, not the printed labels. The cottage version of the label is printed, while the specifications and parameters are not uniform.
6, see annex. Led Tube with regular there in the box with lights attached instructions and specifications, while also equipped with a connector Led Tube or deck; and cottage version of the Led Tube with a box where there is no such attachment because They are able to save the province.
Understand these points, I believe that friends are when purchasing Led Tube with not only care about price.
