Novram
Novram
The industry standard for mechanical strength and electrical insulation. Composed of woven fiberglass cloth impregnated with an epoxy resin binder. Ideal for standard industrial controllers, motherboards, and general-purpose circuitry requiring mechanical stability under diverse ambient environments.
Features a metal base layer (typically aluminum or copper) bonded with a thin, highly thermally conductive dielectric layer and the copper circuit layer. Essential for high-power LED systems, automotive headlights, and power converter components where heat dissipation is critical to prevent thermal breakdown.
Composite Epoxy Materials designed as cost-efficient alternatives to FR-4. CEM-1 uses a paper-based core sandwiched between glass fabric layers, perfect for low-cost, high-volume consumer goods. CEM-3 offers mechanical properties very close to FR-4 but at a reduced material expense.
| Substrate Parameter | FR-4 Grade | CEM-1 / CEM-3 | Metal Core (MCPCB) |
|---|---|---|---|
| Thermal Conductivity (W/m-K) | 0.25 - 0.40 | 0.20 - 0.35 | 1.0 - 4.0+ (Customizable) |
| Glass Transition Temp (Tg) | 130°C - 180°C | 110°C - 130°C | N/A (Metal Base) |
| Dielectric Breakdown (kV) | > 40 | > 35 | > 3.0 (Dielectric Layer limit) |
| Peel Strength (N/mm) | > 1.5 | > 1.2 | > 1.4 |
| Optimal Application Scenarios | General Controllers, Motherboards | Power adapters, low-cost consumer electronics | High-power lighting, automotive electronics, power systems |
Modern vehicles depend heavily on distributed electronic sub-systems, such as gear shifters, climate control panels, and interior ambient LED lights. For these applications, high-durability single-sided MCPCBs provide extreme reliability in high-vibration automotive environments, resisting thermal fatigue over operating ranges from -40°C to +125°C.
Municipal electrical and gas networks deployment demands utility-grade reliability with decades of continuous uptime. Single-sided FR-4 boards are widely used in telemetry modules and power modules due to their electrical separation properties, shielding internal logic units from potential high-voltage grid transients.
In manufacturing sites, electric motors require specialized variable-frequency drives (VFDs) and high-current power switching components. Through-hole single-sided circuits utilizing heavy copper layers (up to 3oz or 4oz) allow high-current loads to flow efficiently without overheating the board material.
Peripheral hardware boards, fan controller boards, and interface cards for high-speed computation (compatible with desktop environments like Intel H311M-G systems or high-bandwidth server memory modules) rely on secondary single-sided controller boards for power routing. These auxiliary boards prevent electromagnetic noise coupling into sensitive data lines.
Moving away from traditional brominated flame retardants to natural, high-Tg bio-resins that significantly reduce environmental footprint during end-of-life recycling without compromising electrical isolation.
Direct Laser Imaging (LDI) eliminates traditional film tools, achieving down to 3 mil trace/space tolerances. Solder mask formulations now include reflective elements for LEDs and high-heat resistance pigments for automotive engines.
Adapting 1/3 oz (12µm) and thinner copper foils to allow ultra-fine track etching for miniaturized IoT nodes, wearable medical trackers, and flexible, light-weight smart labels.
