Frequently Asked Questions
The 94V-0 rating refers to the UL 94 flammability standard. It indicates that the material is flame-retardant and will stop burning within 10 seconds on a vertical specimen, ensuring maximum safety for electronic devices.
FR-4 is used across nearly all electronic sectors, including automotive (engine control), aerospace (avionics), medical (ECG monitors), industrial automation (robot sensors), and consumer electronics (smartphones).
FR-4 has a relatively high dielectric constant, which can lead to signal attenuation at frequencies above several GHz. For extreme high-frequency or RF applications, specialized substrates like Rogers are often recommended.
Common finishes include LF-HASL (Lead-Free Hot Air Solder Leveling), ENIG (Electroless Nickel Immersion Gold), OSP (Organic Solderability Preservatives), and ENEPIG, depending on the required solderability and oxidation resistance.
FR-4 can absorb atmospheric moisture, which may alter its electrical properties. In harsh environments, this can lead to delamination or dielectric loss; therefore, strict humidity control during storage and processing is essential.
Yes, FR-4 is fully compatible with lead-free soldering and is compliant with RoHS standards, making it an environmentally friendly choice for modern electronic manufacturing.
