Smart Metering FAQ
Common insights into metering accuracy, hardware security, and grid connectivity.
How do you ensure measurement accuracy over a 15-year lifecycle?
Accuracy drift is often caused by thermal cycles and oxidation. We utilize high-stability, low-thermal-expansion laminates and premium surface finishes like OSP or ENIG to prevent pad corrosion. Additionally, our soldering processes for metering shunts are strictly controlled to ensure zero resistance drift.
Are your PCBs resistant to high-voltage surges and EMC interference?
Yes. We specialize in layout strategies for high-voltage isolation and noise decoupling. Our boards are designed to pass rigorous IEC/EN electromagnetic compatibility (EMC) tests, ensuring data remains accurate even in "noisy" industrial utility environments.
Do you support integrated wireless modules for remote reading?
Absolutely. We provide RF-optimized PCB fabrication for AMR/AMI systems using NB-IoT, LoRa, Sigfox, and GPRS. We ensure the antenna performance is maximized through precision impedance control on RF-feed lines.
What anti-tampering features can be implemented at the PCB level?
We can implement specialized "tamper grids" or mesh layers within the PCB stack-up. These active circuits detect if the board is being drilled or accessed. We also support layouts for light/magnetic sensors that trigger an immediate memory wipe if the meter casing is opened.
