[KEEP BEST] Product Testing Services: Ensuring Uncompromised Quality

At [KEEP BEST], we recognize that rigorous testing is the cornerstone of delivering reliable PCB and PCBA products. Our comprehensive testing protocols adhere strictly to IPC standards, guaranteeing that every product leaving our facility meets the highest quality benchmarks. With a commitment to excellence, we offer a one-year free repair warranty for any non-PCB external factor-related issues encountered during standard product use. Below is an in-depth overview of our advanced testing capabilities, including specialized programming tests.

Advanced Testing Technologies

AOI Automatic Optical Inspection

Leveraging optical principles combined with image analysis, computer technology, and automatic control systems, our AOI inspection efficiently identifies production-related defects on PCBs. This technology accurately screens out defective products, preventing faulty PCBs from reaching clients or proceeding to subsequent processes. It effectively detects issues such as soldering defects, component misplacement, and surface anomalies, ensuring only quality-assured boards move forward.

FAI First Article Inspection System

Our FAI system features high-precision 10-level sorting with PASS/FAIL indication and voice broadcast functionality. Equipped with serial and parallel equivalent mode selection, automatic function range adjustment, and simultaneous L-RDC testing, it streamlines the first article confirmation process. The one-key screen capture and data recording functions generate detailed first article reports, significantly enhancing verification efficiency and preventing errors at the initial production stage.

ICT (In-Circuit Test)

Based on the customer-provided PCB test plan, our ICT testing includes test points, programs, custom test fixtures, and predefined steps. This method simulates circuit input and output to measure whether electrical values meet specified standards, ensuring the functionality and connectivity of components and traces on the PCB.

X-Ray Inspection

Utilizing X-Ray technology, our inspection equipment penetrates materials of varying densities to generate contrast images, enabling non-destructive evaluation of ultra-fine pitch and high-density PCB internal structures. This allows us to detect hidden issues such as solder bridges, missing components, misalignments, and open circuits without compromising the PCB, ensuring thorough quality control.

3D Solder Paste Inspection (SPI)

Our SPI system effectively evaluates the volume, area, height, XY offset, and shape of solder paste printed on PCBA. It promptly identifies defects like missing paste, insufficient/t excessive solder, solder bridging, misalignment, shape irregularities, and board surface contamination, eliminating potential issues before assembly.

Plug-in Online Visual Inspection

Employing AOI technology, this inspection method targets the DIP (Through-Hole) process, accurately screening out defects such as wrong components, missing parts, reverse placement, extra components, and misalignments. It prevents defective PCBA from being delivered to clients or entering subsequent production stages, maintaining process integrity.

X-Ray Coating Thickness Gauge

This multifunctional instrument conducts comprehensive and precise detection and analysis of coatings, enabling us to verify surface finish thickness and quality. It plays a critical role in enhancing product reliability and optimizing production efficiency.

High and Low Temperature Tester

With a temperature range of -70°C to 150°C and humidity adjustment from 20% to 98%, our tester performs thermal shock and environmental reliability tests. It evaluates the performance of electronic components, automotive parts, aerospace materials, and more under extreme temperature and humidity conditions, ensuring product durability in diverse applications.

PCBA Function Test

Our full-function coverage test ensures every PCBA product delivers reliable and stable performance. It verifies all specified functions, from signal transmission to component operation, to meet customer requirements and application standards.

Oscilloscope Testing

Equipped with a 4-channel, 200Mhz/1G sampling rate high-precision digital oscilloscope, we conduct detailed signal analysis for product R&D, equipment debugging, and maintenance. This tool helps identify and resolve signal integrity issues, ensuring optimal circuit performance.

Programming and Burn-In Testing

On-line and Off-line Program Programming

We offer automated and manual programming services for various memory chips, including EPROM, EEPROM, NOR FLASH, SPROM, and NAND FLASH. Our programming solutions inject precise functionality into components, ensuring they operate as intended in final products. Whether for prototype development or mass production, we guarantee accurate and efficient program implantation.

FCT (Functional Circuit Test)

Aligned with the customer’s test plan, our FCT testing utilizes custom fixtures, programs, and test steps to simulate real-world circuit operation. It measures input and output parameters to verify that all functional specifications are met, providing comprehensive validation for PCB and PCBA functionality.

Commitment to Quality Assurance

At [KEEP BEST], our testing processes are designed to minimize risks and maximize product reliability. By combining advanced equipment, industry-standard methodologies, and a team of skilled professionals, we ensure that every product undergoes thorough evaluation before delivery. Our goal is to provide clients with confidence in the quality, performance, and longevity of their PCB and PCBA solutions, supporting their success in competitive markets.
