What is the recommended incoming inspection procedure for RF components before assembly?
RF Component Incoming Inspection
Incoming inspection is the first line of defense against assembly failures. For RF modules with assembly costs of $500-5000+: investing $10-50 in incoming inspection per component is always justified by the prevention of costly rework and scrap.

|---|---|---|---|
| Performance | High | Medium | Low |
| Cost | High | Low | Medium |
| Complexity | High | Low | Medium |
| Bandwidth | Narrow | Wide | Moderate |
| Typical Use | Lab/military | Consumer | Industrial |

- Performance verification: confirm specifications against the application requirements before finalizing the design
- Environmental factors: temperature range, humidity, and vibration affect long-term reliability and parameter drift
- Cost vs. performance: evaluate whether the application demands premium components or standard commercial grades
- Interface compatibility: verify impedance, connector type, and mechanical form factor match the system architecture

Frequently Asked Questions
What about counterfeit components?
Counterfeit RF components are a significant risk, especially for: obsolete parts (no longer manufactured by the original manufacturer), parts purchased from non-authorized distributors, and high-value components (GaN PAs, precision attenuators). Detection methods: compare the markings (font, logo, date code format) to known-good samples from the authorized manufacturer. X-ray inspection reveals internal construction differences. Decapsulation (destructive) reveals the die and wire bonds for comparison to the authentic design. Buy from authorized distributors whenever possible. If purchasing from the secondary market: require Certificates of Conformance and perform enhanced incoming inspection.
How do I handle ESD-sensitive components?
All semiconductor components (MMICs, transistors, diodes) and most IC packages are ESD-sensitive. Handle in an ESD-safe environment: grounded workbench with ESD mat, wrist strap connected to the ground point, ionized air blower to neutralize static charges on non-conductive materials, and ESD-safe packaging (conductive bags, trays). Open component packages only at the ESD workstation. Never place ESD-sensitive components on non-conductive surfaces (plastic bags, paper). Verify the ESD protection daily using a wrist strap tester and a surface resistivity meter.
What records must I keep?
For AS9100/ISO 9001 compliance: maintain records of: supplier qualification (approved supplier list with periodic audit results), incoming inspection results (pass/fail data, measurement data for sampled units), lot traceability (link each component in the assembled module to its incoming lot number), non-conformance reports (NCRs) for any component that fails incoming inspection (including disposition: return to supplier, use-as-is, or scrap), and corrective action reports (CARs) for suppliers with recurring quality issues. Retention period: typically 7-10 years for commercial, indefinite for military/space.
