1. Look at the package. The LED carrier tape produced by regular led carrier tape manufacturers is produced by SMT patch process and heat sealing and return sealing process. Therefore, the surface of the LED carrier belt is relatively smooth and there are not many particles, and the solder joint extends from the rubber disc to the LED carrier belt in an arc shape. The surface packaging of the fake led carrier tape is uneven, mostly a dot wraps the carrier tape, and there will be different degrees of tin tips, which is a typical phenomenon of pasting.

2. Look at the color of the carrier tape. The sealing tape is divided into black anti-static and transparent non-static. The anti-static sealing bag is convex. If you look closely, you can see from the connection between the upper tape and the rubber disc. The sealing belt is closely connected with the carrier belt, which can be bent arbitrarily without cracking and falling off. If the carrier belt is bent too much, it will crack, and too high temperature during maintenance will also cause the sealing belt to fall off.
