Quality Workflow
Controlled from Material Selection to Final Shipment
For solder pallets and electronic fixtures, quality is not only a final inspection step. LH Stone reviews the application, material grade, machining details and inspection criteria before production, then controls critical dimensions and documentation through the order process.
- Material identification and grade confirmation before machining
- Drawing and application review for manufacturability
- In-process checks for critical features and positioning points
- Final dimensional inspection against approved requirements
- SGS/RoHS-oriented documentation and test reports when applicable
