LED Foam Stick The Quality Of The Foam Belt Is Good Or Bad

 LED foam stick  The quality of the foam belt is good or bad

LED foam rod production because of the low threshold to enter, so the release of this project a lot of people. But experienced people still have the means to identify the regular manufacturers of LED foam belt and cottage version of the LED foam belt (that is, in the rental house by artificial production of products) is from the appearance At first glance. Here to our company products, for example, to talk about how to identify the eyes with LED foam belt quality is good or bad:

Look at the packaging. Regular LED foam strap will be anti-static coil tray packaging, usually 5 meters a volume or 10 meters a roll, and then outside the use of anti-static moisture-proof packaging bags sealed. And the cottage version of the LED foam belt because of cost savings, and the use of recycled coil, and then there is no anti-static moisture-proof packaging bags, carefully read the coil can see the appearance of the label to remove the traces and scratches left.

Look at the label. Regular LED foam straps and rolls are printed on top of the label, rather than the printed label. While the cottage version of the label is printed, while the specifications and parameters are not uniform.

see Attachment. Formal LED foam strap will be attached to the inside of the box with instructions and lamp specifications, but also with LED foam belt connector or deck; and cottage version of the LED foam stick box box is not the Annex, because they are able to save the province.

See solder joints. Formal LED Foam Belt Manufacturers Produced by LED Foam Bars are manufactured using SMT patch processes, using solder paste and reflow soldering processes. As a result, the solder bumps on the LED foam rods are relatively smooth and the amount of solder is not much, and the solder joints are arc-shaped extending from the FPC pads toward the LED electrodes. While the cottage version of the LED foam rods solder joint solder is not uniform, mostly a dot wrapped around the foot, while there will be different levels of tin tip appears, which is a typical phenomenon of manual welding.

See FPC quality. FPC is divided into copper and rolled copper two, copper clad copper foil is protruding, look at the words from the pad and FPC connection to see. And rolling copper is close and FPC as a whole, you can bend any bend without falling off the phenomenon. If you bend over the copper plate will appear off the pad, the maintenance of the temperature is too high will cause the pad off.

Look at the cleanliness of the surface of the LED foam bar. If the use of SMT production process LED foam belt, the surface cleanliness is very good, do not see any impurities and stains. However, if the use of hand-welding process production cottage version of the LED foam belt, the surface no matter how cleaning, will remain stains and cleaning traces, and in the FPC surface will have flux and tin residue residue.

First, the installation instructions and precautions:

1, the installation of the product must be certified professional electrician.

2, from the box when you check out the integrity of the product.

3, the product and flammable materials to ensure that at least 0.2m distance, to ensure that the installation of the zenith has 2 cm high gap, the panel lights can not be all installed in the zenith inside, or the wall of heat, pay attention to low pressure and High-voltage electrical connections are separated.

4, the panel lights on the connection can be from the drilling and the lamp behind the connection can be fixed with a wire clip, to ensure that fixed firmly.

5, to ensure that the lamp power cord has enough length, do not be tension or tangential force. Install the lamp connection to avoid excessive tension, do not make the connection knot. Output wiring should pay attention to distinguish, do not be confused with other lamps.

6, after installation, the panel light low-voltage plug and switch power supply low-voltage plug to connect.

7, non-professional staff shall not be demolished, maintenance, I have the right to unauthorized dismantling, maintenance of the product does not give replacement or warranty service.
