IQC (Incoming Quality Inspection) for High-Quality PCBs by Omini

At Omini, IQC (Incoming Quality Inspection) is a critical step in ensuring the quality and reliability of printed circuit boards (PCBs). Here’s how we manage this essential process:

1. Comprehensive Material Checks:

• Inspect core materials like CCL (Copper Clad Laminate), copper, dry film, solder mask, and silkscreen for defects or inconsistencies.

2. Defect Prevention and Cost Savings:

• Early detection of material defects prevents production delays, reduces waste, and saves costs for both customers and manufacturers.

3. High Attention to Detail:

• Conduct detailed inspections to minimize defective PCBs, avoiding costly rework and ensuring customer satisfaction.

4. Upholding Quality Standards:

• Verify that all materials meet stringent quality standards, ensuring the final PCBs are reliable and high-performing.

5. Commitment to Customer Success:

• By implementing IQC rigorously, Omini ensures that every PCB is built to the highest standards, delivering exceptional value to our customers.

Omini prioritizes IQC as a foundation for producing premium PCBs, reinforcing our commitment to quality and customer satisfaction.

Comprehensive PCB Inspection Services by Omini

At Omini, we prioritize delivering high-quality PCBs through a robust combination of manual and automated inspection methods. Below are key aspects of our inspection process:

1. Manual Visual Inspection

• Detects defects in base materials, solder masks, and silkscreens undetectable by machines.
• Ensures products meet IPC-A-600 Class 2 or 3 and customer-specific standards.
• Conducted by highly trained personnel with access to precision testing equipment.

2. AOI (Automated Optical Inspection)

• Uses high-resolution cameras to identify defects in copper traces and solder masks.
• Enhances quality control while maintaining production speed and reducing waste.
• Ensures consistent product quality, critical for high-precision PCB designs.

3. FAI (First Article Inspection)

• Verifies initial PCB prototypes meet all customer and industry standards before mass production.
• Prevents costly rework by identifying issues early in manufacturing.
• Guarantees PCBs comply with IPC-A-600 acceptance standards and customer requirements.

4. Micro-Section Inspection

• Examines copper plating, dielectric thickness, and solder mask adherence under a microscope.
• Performed four times during production to ensure proper copper plating thickness and quality.
• Identifies hidden defects, ensuring long-term reliability and durability of PCBs.

Comprehensive PCB Testing by Omini

At Omini, we prioritize delivering high-quality PCBs with rigorous electrical and mechanical testing to ensure performance and reliability. Below are essential testing methods in our PCB production:

1. Electrical Testing for Open/Short Circuits

• Detects defects in PCB traces, preventing performance and safety issues.
• Includes Flying Probe Testing for prototypes and Bed-of-Nails Testing for mass production.
• Ensures precise testing with documented results for future inspections.

2. TDR Impedance Testing

• Critical for high-speed PCB designs like PCI-Express and SATA.
• Identifies impedance discontinuities to maintain signal integrity.
• Provides fast, accurate measurements using Time Domain Reflectometer (TDR) technology.

3. Solderability Testing

• Simulates soldering processes to verify reliable component attachment.
• Detects issues like solder mask peeling or delamination under high temperatures.
• Guarantees smooth SMD and PTH assembly for all PCB designs.

4. Flying Probe vs. Bed-of-Nails Testing

Flying Probe Testing:
• High equipment cost but no fixture required.
• Suitable for prototypes with low test speeds.
• Delivers high reliability for detailed inspections.

Bed-of-Nails Testing:
• Medium equipment cost but requires a fixture.
• Ideal for mass production with high test speeds.
• Ensures high reliability for large-scale testing.
