Your Biggest Pain Points
- Escalating component costs: 2025‑2026 data shows a 12% YoY rise in transformer prices for US OEMs.
- Inconsistent quality & certification gaps: Failed CE/FCC audits cost an average of $45k per batch.
- Long lead times: Typical Asian suppliers need 6‑8 weeks, delaying product launches.
- Limited customization: One‑size‑fits‑all designs force you to redesign PCBs.
- Supply‑chain opacity: No real‑time tracking leads to stock‑outs and production downtime.
