2. The Pain Points You’re Facing

High component cost – Traditional suppliers charge 15‑20% premium for low‑volume orders.
Inconsistent quality – 30% of US OEMs report failure rates above 5% due to tolerance drift.
Long lead times – Average 6‑8 weeks from order to delivery, disrupting production schedules.
Limited customization – Off‑the‑shelf networks cannot meet specific impedance or temperature‑range requirements.
Regulatory uncertainty – Lack of CE, FCC, RoHS compliance leads to costly re‑certifications.

Result: Delayed launches, higher total cost of ownership, and lost market share.
