SA-FL21 Printed Circuit Board

SA-FL21 Printed Circuit Board 

Product Details Introduction

SA-FL21 is a rigid PCB specifically designed for JRC brand industrial grade alarm systems. It uses a 6-layer high TG FR-4 substrate and precision manufacturing technology, and is suitable for harsh scenarios such as ships and industrial control. Its core features are as follows:

1. 6-layer high-density wiring structure

Adopting a 6-layer stacked design with a minimum line width/spacing of 3.0mil, high-density component layout is achieved through precise stacking configuration to meet the complex circuit interconnection requirements of alarm systems.

2. Precise impedance and signal control

The impedance tolerance is precisely controlled within ± 5%, the signal transmission loss is low, and it can stably carry high-frequency alarm signals, avoiding false triggering caused by signal interference.

3. High end substrates and surface technology

Using high TG FR-4 substrate, combined with chemical gold deposition process (gold layer 0.1 μ m, nickel layer 2-3 μ m), 1oz copper foil thickness, excellent corrosion resistance and weldability.

4. Tolerant to harsh and wide temperature environments

The working temperature range is -40 ℃~+85 ℃, which can withstand extreme temperature conditions such as ships and outdoor environments, and meet the 24-hour continuous operation requirements of industrial grade equipment.

5. Strengthen security protection design

The flame retardant rating of the substrate reaches 94V-0 level, with a compliant safety distance design and insulation resistance of ≥ 10 ¹⁰ Ω, effectively preventing short circuit and fire risks and ensuring system safety.
