At LinInno, product quality is not just about performance — it’s about consistency, reliability, and attention to detail. While there are many advanced testing methods available, one of the most practical and essential quality control steps we rely on is visual inspection.

Visual inspection allows us to identify surface-level and structural defects before products are shipped, ensuring that every connector meets our standards for appearance and build integrity.

✅  What Is Visual Inspection?

Visual inspection involves carefully examining each connector — either individually or in batches — to detect any external or assembly-related defects. This inspection is typically performed by trained technicians and/or automated imaging systems under good lighting or magnification.

✅ What Do We Look For?

During visual inspection, our team checks for:

• Deformation or cracks in the plastic housing or terminals
• Bent, missing, or misaligned pins
• Flashing or burrs from the molding process
• Incomplete insertions or poor terminal seating
• Surface contamination, such as dust, oil, oxidation, or scratches
• Color and marking accuracy for identification and assembly alignment
• Damage from packaging, handling, or ESD

These issues, while often cosmetic, can impact performance or cause assembly problems on the customer’s production line. That’s why they’re caught and addressed before shipping.

✅  Why Visual Inspection Matters

• It ensures mechanical compatibility — helping customers avoid mating issues or faulty connections.
• It helps maintain consistent appearance and brand quality.
• It serves as the final check before delivery, reinforcing trust and satisfaction.

In high-volume manufacturing, even minor visual defects can cause downtime, rework, or failure. That’s why we treat visual quality control as a core part of our quality assurance process.

✅  Final Check Before Shipment

Before packaging and shipment, each batch undergoes final visual inspection as part of our outgoing quality control (OQC). Products that don’t meet our visual criteria are reprocessed or rejected — ensuring only the best connectors leave our facility.

At LinInno, we believe that quality is seen in the details. Visual inspection is more than just a step — it’s a standard.
