This 2-layer FR4 PCB addresses the needs of industrial automation, sensor networks, and power management applications requiring a balance of compact design and robust performance. С размерами 100×79.69mm и 1.6ММ толщина, the board offers a versatile platform for integrating microcontrollers, communication interfaces, and power components in a space-efficient form factor. Constructed from FR4 material, it ensures stable electrical insulation (Диэлектрическая постоянная εr = 4,5) and mechanical rigidity, suitable for operation in moderate-temperature industrial environments with minimal vibration.
- 2-Layer Stackup:
- Top and bottom signal layers with ground/power planes implemented via copper pours, reducing electromagnetic interference (Эми) for basic signal integrity.
- Split power domains (НАПРИМЕР., 5V/3.3V) separated by isolation traces to minimize cross-talk between analog and digital sections.
- 1Унция (35мкм) Толщина меди:
- Supports up to 8A current in power traces (≥1mm width) for motor drivers or solenoid valves.
- Enables fine-line routing (minimum line/space: 100μm/100μm) for low-speed signals (UART, I2C) and component density.
- Green LPI Solder Mask:
- Standard industrial color for easy visual inspection during assembly and maintenance.
- Chemical resistance against oils, coolants, and cleaning agents common in manufacturing environments.
- Загадочная поверхность отделка:
- 3–5μm nickel layer for corrosion protection; 0.05–0.1μm gold layer ensures reliable solderability for both SMT and DIP components, even after long-term storage.
- SMT+DIP Mixed Assembly:
- Пост: Accommodates 0402 пассивные компоненты, SOIC/SSOP ICs, and 0.5mm pitch QFP packages for high-density integration.
- DIP: Supports through-hole connectors (НАПРИМЕР., 0.1″ headers, терминальные блоки) and relays for robust field wiring in industrial setups.
- Precision Fabrication:
- Laser direct imaging (LDI) for 100μm trace accuracy, ensuring consistent routing across the board.
- Electrolytic copper plating with uniform thickness verification to maintain conductivity.
- Comprehensive Testing:
- 100% automated optical inspection (Аои) to verify solder mask coverage and silkscreen clarity.
- Flying probe testing for electrical continuity (≤0,1o) и изоляция (≥100 МОм) to eliminate open/short circuits.
- Тепловые тестирование (260°C reflow cycles) to ensure solder joint reliability during assembly.
- Standards Compliance:
- Meets IPC-6012 Class 2 standards for industrial electronics.
- RoHS/REACH compliant for lead-free and hazardous substance restrictions.
- Industrial Sensor Modules:
Integrates temperature, влажность, or pressure sensors with analog signal conditioning and wireless communication (НАПРИМЕР., LoRa, BLE).
- Motor Control Units:
Drives low-voltage DC motors in conveyor systems, featuring PWM control, current limiting, and overheat protection.
- Коммуникационные интерфейсы:
Enables protocol conversion (НАПРИМЕР., RS-485 to USB) for legacy industrial equipment integration with modern control systems.
- Power Distribution Panels:
Manages 24V DC power distribution to multiple loads, with circuit protection (fuses, TVS diodes) and status indication LEDs.
