Quality & Certifications

Quality at US Micro Products is embedded in every stage of our process from design through delivery. When your display goes into a surgical instrument, a cockpit panel, or an industrial controller, the quality of that display directly affects the safety and performance of the end product. We engineer and inspect accordingly.

Our philosophy has always been performance over price. We compete on reliability, consistency, and engineering support as much as cost. Every display we ship is expected to meet the specifications we committed to, backed by testing and documentation customers can rely on for critical applications.

ISO 9001 Certification

US Micro Products maintains ISO 9001 certification for our quality management system. This certification covers our complete operation: design, sourcing, manufacturing oversight, inspection, testing, and delivery of custom display solutions.

Our QMS provides:

Document control — All specifications, drawings, procedures, and work instructions are revision-controlled and accessible
Change management — Engineering changes follow a formal ECN process with impact assessment, customer notification, and validation
Corrective and preventive action (CAPA) — Systematic root cause analysis and corrective action for any quality escape or process deviation
Management review — Regular review of quality metrics, customer feedback, and continuous improvement initiatives
Internal audits — Scheduled audits verify compliance and identify improvement opportunities

Incoming Inspection and Testing

Every display shipment undergoes incoming inspection before it ships to our customers:

Visual inspection — Cosmetic quality, pixel defects, polarizer condition, connector integrity, and labeling verification
Dimensional verification — Critical mechanical dimensions checked against drawing specifications
Electrical testing — Power consumption, interface signal integrity, backlight performance, and touch sensor functionality
Optical measurement — Brightness, contrast ratio, color coordinates, and viewing angle verification on sampling plans appropriate to order volume and application criticality
Environmental screening — For high-reliability applications, displays undergo thermal cycling, humidity exposure, or vibration screening per customer specifications

Industry-Specific Quality Standards

Military and Defense (MIL-STD)

Defense display applications demand the highest reliability and environmental performance. Our quality processes support:

MIL-STD-810 — Environmental testing methods for temperature, humidity, altitude, vibration, and shock
MIL-STD-461 — EMI/EMC testing requirements for military electronic equipment
MIL-STD-883 — Test methods for microelectronics applicable to COB and wire-bonded display assemblies
ITAR compliance — We understand the export control requirements for defense display programs and manage our supply chain accordingly

We work with defense OEMs including Lockheed Martin and Honeywell to ensure that display components meet the specific qualification requirements of their programs.

Medical Devices (FDA Considerations)

US Micro Products is a display component supplier, not a medical device manufacturer. However, we design our quality processes to support our medical device OEM customers' regulatory requirements:

Design documentation — Complete material specifications, test reports, and traceability records compatible with FDA Design Controls (21 CFR 820)
Supplier qualification — Our ISO 9001 QMS and documentation practices support medical device companies' supplier qualification requirements
Component traceability — Full lot traceability from raw materials through finished display assembly
Change notification — Formal notification process for any material, process, or supplier change that could affect form, fit, or function
Long lifecycle support — Medical device lifecycles of 7–15+ years require proactive obsolescence management. See our EOL parts program.

Automotive Quality

Automotive display applications require reliability under extreme thermal, vibration, and lifecycle conditions. Our quality processes address:

AEC-Q qualification — Support for component-level qualification testing per Automotive Electronics Council standards
PPAP — Production Part Approval Process documentation for automotive OEM supplier qualification
FMEA — Failure Mode and Effects Analysis as part of our design process for automotive display projects
Extended temperature validation — Testing across -40°C to +85°C (or wider) operating temperature ranges per automotive specifications

Traceability

Every display assembly we ship is traceable. Our traceability system links each unit to:

Display panel manufacturer and lot number
Component lot numbers (backlight LEDs, touch sensors, cover glass, FPCs)
Inspection records and test data
Production date and operator records
Shipping and delivery records

This traceability supports warranty resolution, field failure analysis, and regulatory compliance for industries that require it.

Continuous Improvement

We track quality metrics including:

First-pass yield rates
Customer return rates and RMA analysis
On-time delivery performance
Supplier quality scorecards
Corrective action effectiveness

These metrics drive our continuous improvement program and are reviewed regularly by management. When we identify a trend or a process gap, we address it systematically — not reactively.
