Packaging carrier refers to the plastic carrier widely used in IC, resistance, inductance, capacitance, connector, fuse, switch, relay, connector, oscillator, diode, triode and other SMT electronic components packaging. According to the use of the carrier belt, it can be divided into: IC special carrier belt, transistor special carrier belt, chip LED special carrier belt, chip inductance special carrier belt, integrated SMD carrier belt, chip capacitor special carrier belt, SMT connector special carrier belt, etc. According to the use of the carrier belt, it can be divided into: IC special carrier belt, transistor special carrier belt, chip LED special carrier belt, chip inductance special carrier belt, integrated SMD carrier belt, chip capacitor special carrier belt, SMT connector special carrier belt, etc. According to the material of the belt, it can be divided into PS belt, ABS belt, pet belt, PC belt, hips belt, PE belt, etc. Belt carrying production equipment: belt carrying equipment is also called belt forming machine. At present, there are mainly two types of belt forming machines: roller type and plate type. The difference between the two lies in the difference of the forming die. Production materials of belt: PS, ABS, pet, PC, hips, PE and other plastic materials. Special requirements can be made of metal.

PC material, polycarbonate (polycarbonate), abbreviated as PC, is a colorless and transparent non qualitative thermoplastic material. Its name comes from its internal CO3 group. Chemical properties of PC: polycarbonate is acid and oil resistant. Polycarbonate is not resistant to ultraviolet light and strong alkali. Physical properties of PC: polycarbonate is colorless, transparent, heat-resistant, impact resistant, flame-retardant, and has good mechanical properties at ordinary use temperature. Compared with polymethyl methacrylate, polycarbonate has better impact resistance, high refractive index, and good processability. It has UL94 V-0 flame retardant performance without additives. The disadvantage of PC is poor wear resistance. Some polycarbonate devices for wear-resistant applications require special surface treatment. PS refers to polystyrene, which is a thermoplastic synthetic resin. The largest application field is electronics and electrical industry. PS: belongs to polystyrene, commonly known as hard glue. The Chinese name is general user polystyrene, and the English name is general purpose polystyrene, which is abbreviated as PS in the plastic industry. Main use: used for making lampshade, instrument shell cover, toy, etc. Physical characteristics: easy to burn, continue to burn after leaving the open fire, soften and froth when burning. The flame is orange yellow, which produces thick black smoke carbon beam, and produces special smell of styrene monomer.

1. The flat type belt forming machine is suitable for the belt of more than 12mm, especially for the belt with Ko greater than 4mm; the stability of the plate assembly airborne belt forming is poor, and the P2 and F values are difficult to control, so it is difficult to do precision forming.

2. The roller type belt carrier has a forming system composed of a concave die and a convex die. The precision of the convex die can ensure the precision of belt carrier forming. The current equipment can reach ± 0.05mm, and the imported belt carrier forming machine can reach ± 0.03mm.
