A Full Suite of Testing Services for Superior Product Reliability

SisTech Manufacturing offers a comprehensive range of testing and inspection services to guarantee the quality and functionality of your printed circuit board assemblies (PCBAs). We understand that in today’s demanding industries, like aerospace and defense — sectors we actively serve — failure is not an option. We utilize advanced equipment and rigorous procedures to build-in quality at every step of the manufacturing process, minimizing rework, eliminating escapes, and ensuring mission success. Our services include:

Precision Defect Identification with Mirtec 2D and 3D AOI

High-Speed, Accurate Inspection

SisTech utilizes Mirtec 2D and 3D Automated Optical Inspection(AOI) machines for high-speed, accurate inspection of components and solder joints. Our systems, located at our Bend, OR facility, are calibrated to identify even the slightest deviations from your design specifications. This rapid and precise inspection is critical for maintaining high throughput without sacrificing quality. Every assembly will receive an AOI inspection multiple times throughout the production process.

3D AOI: The Next Level of Precision

Our 3D AOI technology provides detailed height measurements and image comparison capabilities, enabling us to identify subtle defects that 2D systems may miss, such as lifted leads, insufficient solder, and component coplanarity issues. This is particularly important for complex assemblies with fine-pitch components. The added dimension of analysis significantly enhances our defect detection capabilities.

Adherence to IPC-A-610 Standards

AOI ensures that all components are correctly placed and soldered according to IPC-A-610 standards, a globally recognized benchmark for electronics assembly quality. Our commitment to these standards reflects our dedication to providing world-class manufacturing services. We can confidently serve customers across the Pacific Northwest and beyond, knowing our processes meet the highest industry requirements.

Unparalleled Defect Detection with Nordson DAGE X-Ray

Unveiling Hidden Flaws with Advanced Technology

Our Nordson DAGE Automatic X-ray system with X-Plane CT Scan technology provides unparalleled visibility into your PCBAs. This allows us to detect hidden defects such as solder voids, shorts, opens, and component misalignment, even within complex, multi-layered boards and BGA components. For industries where even microscopic flaws can have significant consequences, this level of inspection is essential.

X-Plane CT Scanning: A Deeper Dive

The X-Plane CT Scan capability goes beyond traditional X-ray, providing detailed cross-sectional views of your assembly and components. This allows our technicians in Bend, OR, to analyze solder joints and component placement with unprecedented accuracy, ensuring the integrity of even the most intricate designs.

Ensuring Long-Term Reliability

X-ray inspection is crucial for ensuring the long-term reliability of high-density assemblies, particularly for applications in demanding environments. We proactively identify potential weak points that could lead to failure over time, preventing costly problems down the line.

Verifying Performance and Functionality

Real-World Simulation for Optimal Performance

Functional testing verifies that your PCBA performs as intended in its final application. We closely follow test procedures based on your specifications to simulate real-world operating conditions. This ensures that the assembled product meets all performance requirements before it leaves our facility in Bend, OR. This step is crucial to ensuring that the final product functions flawlessly in its intended environment.

Tailored Testing for Your Specific Needs

We understand that every product is unique. Our team works closely with you to understand your specific testing requirements and develop a customized plan that addresses your individual needs. This tailored approach ensures comprehensive testing coverage.

Beyond Pass/Fail: Identifying Performance Issues

Functional testing can identify issues that may not be detectable through visual or automated inspection alone. We go beyond simply checking for functionality; we analyze performance characteristics to ensure optimal operation. This proactive approach helps to prevent potential problems and improve overall product quality.

Comprehensive Component-Level Testing

Custom Test Fixtures: Pinpointing Component Failures

Bed of nails testing is a powerful method for verifying the individual functionality of components and circuits on your PCBA. If you are desiring more than technician-conducted functional testing, we can work with partners to have a custom test equipment fixture manufactured to test each component against its expected parameters, identifying any faulty or out-of-tolerance parts. This extensive process provides a high level of fault coverage and helps ensure that every component is functioning correctly.

Ensuring Individual Component Reliability

A custom test fixture or JTAG testing isolates and identifies some of the smallest system or component-level defects, preventing them from impacting the overall performance of your assembly. This is particularly vital for complex boards with hundreds or thousands of components.

Maximizing Fault Coverage

These processes provide a high degree of certainty that your PCBA is free from component-level defects. Meticulous testing helps to minimize the risk of field failures and ensure long-term product reliability.

Rigorous Visual and Quality Checks

The Human Element: Expert Visual Inspection

In addition to our automated testing, SisTech performs thorough visual inspections at various stages of the assembly process. Our IPC-A-610, IPC 7711/7721, and J-STD-001 certified inspectors, based in Bend, OR, have decades of experience. They meticulously examine every assembly for any visible defects, ensuring adherence to industry standards and customer specifications. This human expertise complements our automated systems, providing an extra layer of quality assurance.

Lot Tracking and Traceability: Complete Accountability

When requested, we can perform lot tracking and traceability for all assemblies, providing a complete audit trail from component sourcing to final testing. This allows quick identification and addressing of any potential issues between batches, and provides customers with full transparency throughout the manufacturing process. This is especially valuable for clients in regulated industries, such as aerospace, medical, and defense.

Multi-Stage Inspection for Maximum Confidence

Our visual inspections are conducted at multiple points in the production process, ensuring that any potential issues are identified and corrected as early as possible. This proactive approach minimizes rework and ensures the highest possible quality.
