(4) PI Polyimide Carrier Tape (Special)
Ultra high temperature resistance of 200 ℃+, expensive price
Applications: Military chips, high-temperature power devices, vehicle power ICs, aerospace electronics small batch packaging.
2、 Classified by molding process
1. Embossed carrier tape (vacuum forming/mold embossing, plastic specific)
The depth and shape of the cavity can be customized, and large/irregular components are preferred
Scenario: IC, connector, shielding shell, LED beads, special-shaped hardware terminals (12~88mm full width).
2. Stamping carrier tape (punched through/semi transparent, paper tape+thin PE)
Fixed cavity, limited depth, only thin small parts
Scenario: Chip resistor capacitor, micro diode, all series with 8mm standard narrowband.
3、 Classified by anti-static level (mandatory differentiation for precision components)
Insulation type (>10 ¹¹Ω): no anti-static, ordinary resistance and capacitance, low-cost plug-in small parts, non sensitive components
Dissipative anti-static (10 ⁶~10 ¹⁰ Ω, most commonly used): chips, LEDs, MOSFETs, crystal oscillators, consumer/car universal models
Conductive type (10 ³~10 ⁵ Ω): ultra-high precision IC, BGA, power devices, military/automotive grade chips, produced in a strong electrostatic environment
4、 According to width specifications (standard JEDEC size)
4/8mm: 0201/0402 Resistive capacitance, micro diode (maximum usage, paper tape+PS tape)
12/16mm：SOT、 Small LED, small inductor (PS/PET)
24/32/44/56/72/88mm：SOP、QFN、 Connectors, shielding covers, large inductors (mainly PC)
