Knowledge of carrier tape forming machine:

(1) The flat carrier tape forming machine is suitable for belts with a thickness of more than 12mm, especially those with a Ko greater than 4mm; The forming stability of panel airborne belt is poor, and it is difficult to control P2 and F values, so it is difficult to make precision forming.

(2) The roller carrier tape has a forming system composed of a female die and a male die. The precision of the male 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.

Carrier tape refers to the plastic carrier widely used in the packaging of SMT electronic components such as IC, resistance, inductance, capacitance, connector, led, fuse, switch, relay, connector, oscillator, diode and triode.

Physical properties of PC: polycarbonate is colorless and transparent, heat resistant, impact resistant and flame retardant. It has good mechanical properties at ordinary service temperature. Compared with polymethylmethacrylate, polycarbonate has good impact resistance, high refractive index and good processability. It has UL94 V-0 flame retardant 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, a thermoplastic synthetic resin.

PS: polystyrene, commonly known as hard glue.

PC material, namely polycarbonate, abbreviated as PC, is a colorless, transparent and amorphous thermoplastic material. Its name comes from its internal CO3 group.

PC chemical properties, polycarbonate acid resistance, oil resistance; Polycarbonate is not resistant to ultraviolet light and strong alkali.
