How to Separate the Quality of LED Patch LED Lamp Beads?

The LED patch lamp belt is still buying regular manufacturers to have quality packaging. Look at the cleanliness of the LED patch lamp with an overview: adopt the LED patch lamp belt produced by SMT process, the cleanliness of its overview is very good, no impurities and stains can be seen. The LED patch lamp belt produced by the hand welding process, regardless of the cleaning, the city residue with stains and cleaning the traces of the city. Look at the packaging: The regular LED patch lamp belt will be packaged with anti -static roll plates, 5 meters or 10 meters of volume, and then the inside of the packaging is used to use the secret seal of the moisture -proof packaging bag. The LED lamp belt of the robber version takes the receiving roll disk, and there is no anti -static moisture -proof packing bag. Carefully see the scroll disc. Look at the label LED lamp bead model and picture: the regular LED patch lamp belt packaging bag and the cities on the roll plate have print labels, not printing labels. Look at the solder point: The LED lamp band produced by the regular LED patch lamp is the SMT patch process, which is produced with a sacral paste and backwing welding. Therefore, the solder joints on the LED patch lamp are slippery than the force and the amount of weld is not large. The solder joints are arc -shaped from the FPC pad to the LED electrode. Look at the quality of FPC: FPC is divided into copper and pressing copper. The copper foil of the copper plate is protruding. The pressure extension copper is closely intimate and the FPC is integrated, which can be bent freely without showing the phenomenon of pads off. If the copper plate is too bending, the pads will fall off if the bend is too much. If the high crosses during maintenance, the pad will also cause the pad to fall off.
