For Rectangular Enameled Copper Wire manufacturers, strictly controlling the quality of the rectangular copper wire in the feeding process is an important responsibility of the IQC of the quality department of the manufacturer. From what aspects can we judge whether the rectangular enameled copper wire is qualified?
The tinned copper flat wire must be silver/brown (bright), and the bare copper flat wire must be reddish brown with bright luster and no dark spots, black or finger marks. When a fingerprint touches a flat copper wire, it will leave a trace in all likelihood. The hand points out the sweat, but the size of the sweat drops, even if people’s eyes can’t see the sweat drops from the fingers, it doesn’t mean there is no. After the copper wire, it is easy to cause the flat copper wire to oxidize, and then turn black or even black.
The thickness tolerance of flat copper wire is generally: 1) thickness 1) 0.035mm or 0.05mm flat enameled wire thickness tolerance is 0.005mm.. 2) 0.1 mm thick flat copper wire thickness tolerance is 0.01 mm.
The ductility of rectangular enameled copper wire is the core research point of rectangular copper wire. It can be called "soft" wire because the rectangular copper wire has sufficient ductility.
