2-layer FR4 TG170 PCB is engineered for applications requiring robust current handling and reliable performance in a cost-effective design, ideal for power supplies, LED drivers, and industrial control modules. Xây dựng từ FR4 TG170 material (glass transition temperature 170°C), the PCB withstands high-temperature environments, making it suitable for components that generate significant heat. Các 1.2độ dày mm balances rigidity with weight, Trong khi 2Oz (70μm) Độ dày đồng on both layers supports high currents (lên đến 15a mỗi dấu vết), minimizing voltage drop and resistive heating.
Được thiết kế trong a 1×4 Định dạng bảng điều khiển, the PCB optimizes production efficiency for mass manufacturing, reducing material waste and lowering costs. Each panel contains four identical boards, streamlining assembly processes for high-volume orders. Các Mặt nạ hàn LPI màu xanh lá cây protects circuitry from moisture and chemical damage, Trong khi Silkscreen trắng provides clear component marking for easy assembly and maintenance. Các Đồng ý (Điện phân Niken Vàng) surface treatment ensures excellent solderability: lớp niken (3Mạnh5μm) Thêm độ bền, và lớp vàng (0.05Cấm0,1mm) ngăn chặn quá trình oxy hóa, maintaining reliable connections over time.
A key feature is POFV (Plated Over Filled Vias) technology, where vias are filled with conductive material and plated to create a smooth, void-free surface. This eliminates the risk of solder wicking or thermal stress failure, critical for components subjected to repeated reflow cycles. POFV also enables via-in-pad designs, allowing tighter component spacing and more efficient routing in dense layouts.
Manufacturing processes prioritize precision and quality:
- Phân tích DFM optimizes panelization for minimal breakage during depaneling.
- Mạ đồng điện phân ensures uniform 2OZ thickness, verified by cross-sectional tests.
- Laser drilling creates vias with ±10μm accuracy before POFV filling.
- 100% Kiểm tra AOI checks solder mask coverage and silkscreen clarity.
- Kiểm tra ứng suất nhiệt confirms reliability at 260°C reflow temperatures.
Engineers will appreciate the PCB’s versatility in both power and signal applications. In consumer electronics, it suits chargers and adapters requiring high-current handling. Trong môi trường công nghiệp, it excels in motor controls and power distribution blocks, where TG170 material ensures stability in warm environments. The 1×4 panel format is ideal for OEMs seeking economies of scale without compromising on performance.
