1、 Process characteristics
The manufacturing of 94V0 circuit boards must strictly adhere to the dual requirements of fire prevention and electrical performance, with key processes including:
Substrate selection:
The commonly used substrates are flame-retardant FR-4 (fiberglass cloth+epoxy resin) or composite paper substrates (such as CEM-1), which achieve V-0 grade by adding brominated flame retardants.
The aluminum substrate adopts a structure of "copper layer+insulation layer (PP)+aluminum bottom plate", which balances heat dissipation and flame retardancy.
Key flame retardant process:
Laminated control: High temperature and high pressure pressing ensures uniform resin penetration, avoids delamination, and activates flame retardants.
Surface treatment: optional tin spraying (lead-free), immersion gold, OSP (organic solder mask) or ENIG (chemical nickel gold), all of which must comply with RoHS lead-free standards.
Solder mask coating: Covering with green or black solder mask ink (hardness>5H) to further isolate oxygen and suppress flame spread.
Quality Control:
Combustion test: Strictly verify the self extinguishing time and drips according to UL 94 V-0 standard.
Electrical testing: on-off test (ET), withstand voltage test (≥ 1.6kV/mm) to ensure insulation reliability.
2、 Core advantages
The core value of the 94V0 circuit board lies in safety and environmental adaptability:
High flame retardant safety:
Rapid self extinguishing in the presence of open flames significantly reduces the risk of electronic device fires and meets safety requirements in fields such as home appliances and automobiles.
Stable environmental adaptability:
Temperature resistance: Operating temperature range of -45 ° C~150 ° C (some aluminum substrates can reach 288 ° C), compatible with lead-free soldering process.
Chemical and moisture resistance: Resist chemical corrosion and high humidity in industrial environments, ensuring long-term reliability.
Environmental compliance:
Support RoHS processes such as lead-free tin spraying and gold deposition, restrict harmful substances such as lead and mercury, and comply with European and American environmental directive 69.
Cost effectiveness:
Paper based 94V0 (such as FR-1) has a cost about 30% lower than FR-4, making it suitable for large-scale consumer electronics products
application area
The 94V0 circuit board is widely used in the following scenarios due to its flame retardancy and stability:
Consumer Electronics:
Smartphone chargers and home appliance control boards (such as rice cookers and air conditioning remote controllers) require safety certification.
Industrial equipment:
PLC controller, sensor interface board, resistant to high temperature and oil pollution environment in the factory.
Automotive Electronics:
The in car entertainment system and ECU control unit meet the requirements of vehicle grade vibration and temperature shock.
Medical equipment:
Monitor and portable diagnostic equipment rely on electrical stability and biosafety.
Communication and Energy:
4G/5G base station antenna board (such as Rogers RO4730G3), LED driver power supply, requiring high frequency, low loss or efficient heat dissipation
