High flame retardancy: the core guarantee of safety
Testing standards:
Vertical burning test: the sample burns for 10 seconds in the, and the self-extinguishing time after the removal of the fire source ≤ 10 seconds, and there is no burning drips to ignite the cotton wool.
Comparison with other grades: V-1 (self-extinguishing time ≤ 30 seconds), V-2 (allowing drips to ignite wool).
Application scenarios:
Automotive electronics (such as ECU control module), industrial power equipment, household appliances (air conditioners, washing machines) other fields with strict fire protection requirements.
Stable electrical performance;
High insulation strength:
Surface resistivity ≥10⁶ MΩ (remains stable in humid and hot environments), the risk of electric leakage.
Arc resistance:
Withstand voltage ≥1000V/mm (1mm thickness), suitable for high-voltage (such as power modules, charging piles).
Dielectric constant (Dk):
Typical value 4.5~5.5 (1MHz, meeting the needs of most low-frequency to medium-frequency circuits.
Mechanical strength and high-temperature resistance
Bending strength:
FR-4 substrate (V-0 grade) has a bending strength ≥30 MPa, superior to low-end materials such as CEM-1 (250 MPa).
Welding temperature resistance:
Glass temperature (Tg) ≥130℃, supports lead-free welding processes (peak temperature 260℃).
Coefficient of thermal expansionCTE):
CTE ≤14 ppm/℃ on X/Y axes (≤50 ppm/℃ on Z axis), reducing the risk cracking in the walls of holes at high temperatures.
