In flexible printed circuit (FPC) manufacturing, polyimide (PI) and SH260 are two dominant substrate materials. As an ISO 9001/IATF 16949/ISO 13485 certified manufacturer, STHL breaks down their key differences:

1. Thermal Resistance

• PI:
Long-term: 260°C | Short-term: 300°C (ideal for high-temp reflow)

• SH260:

Long-term: 220°C | Short-term: 250°C (more cost-effective)

2. Mechanical Properties

→ PI:

Bend cycles >1 million (best for dynamic applications)

→ SH260:

Higher rigidity (suited for static installations)

3. Application Recommendations

✓ Automotive/Aerospace: PI (high-temp & vibration resistance)

✓ Consumer Electronics/Medical: SH260 (balanced cost-performance)
