• RohS/REACH compliance: Mandatory for products sold in the EU and other regulated markets.
• IATF 16949 or ISO 13485: Required for automotive and medical device applications, respectively.

While not all suppliers list certifications upfront, consistent on-time delivery rates above 98%, documented DFM (Design for Manufacturability) reviews, and first-article inspection reports are strong indicators of process discipline.

2. Production Capacity and Responsiveness

Operational responsiveness directly impacts your time-to-market. Key performance indicators (KPIs) to assess include:

• Response time ≤2 hours: Fast communication reflects organizational agility.
• On-time delivery rate ≥98%: Demonstrates logistical reliability.
• Minimum monthly capacity >50,000 units: Ensures scalability for growing demand.
• In-house capabilities: Look for full-service offerings including SMT, DIP, conformal coating, and functional testing.

Suppliers offering real-time order tracking, weekly production updates, and transparent factory audits provide greater visibility and risk mitigation.

3. Customization and Transaction Security

Modern electronics often require tailored solutions. Confirm whether the supplier supports:

• Custom material selection (e.g., FR-4, Rogers, polyimide)
• Color-coded silkscreen, custom labels, and branded packaging
• Test jig design and integration
• Gerber file optimization and BOM validation services

Reorder rate—a metric reflecting customer retention—is a powerful proxy for satisfaction. Rates above 60% suggest consistent service quality and trust. Always request pre-production samples and use secure payment methods such as Trade Assurance to protect transactions.
