IEC 61189 PCB Solder Joint NVH Durability Testing
The International Electrotechnical Commission (IEC) standard IEC 61189 is a comprehensive guide for the testing and certification of printed circuit boards (PCBs). One crucial aspect covered by this standard pertains to the durability and reliability of solder joints, particularly in environments where noise, vibration, and harshness (NVH) are significant factors. This service focuses on ensuring that PCBs can withstand these environmental stressors without compromising performance or integrity.
IEC 61189 specifies a series of tests designed to evaluate the robustness of solder joints under NVH conditions. The test parameters include vibration frequency, amplitude, and duration as well as sound pressure levels, all of which are critical in automotive applications where NVH is paramount for passenger comfort and vehicle safety.
The process begins with precise specimen preparation, ensuring that each PCB is representative of the production batch it comes from. This involves cleaning components and boards to remove any contaminants that could affect test results. Once prepared, the PCBs undergo a series of mechanical and acoustic tests designed to simulate real-world conditions they will face in automotive environments.
Testing typically includes immersion in water or salt spray for corrosion resistance testing followed by exposure to vibration and sound pressure levels to assess NVH durability. The use of advanced instrumentation ensures that every parameter is measured accurately, providing a detailed report on the solder joint's performance under these conditions. This data helps manufacturers identify potential weaknesses early in the development process.
Compliance with IEC 61189 not only enhances product reliability but also supports broader goals such as reducing warranty costs and improving customer satisfaction by ensuring products meet high standards of quality right from the start.
| Environmental Factor | Test Parameter | Test Duration | Expected Outcome |
|---|---|---|---|
| Vibration Frequency | 5 Hz to 1 kHz | 30 minutes | Evaluation of solder joint durability under vibration. |
| Sound Pressure Level | 85 dB to 120 dB | 1 hour | Determination of sound insulation properties of PCBs. |
| Vibration Amplitude | 1 mm peak-to-peak | 30 minutes | Evaluation of solder joint resistance to mechanical shocks. |
By adhering strictly to IEC 61189, our laboratory ensures that all tests are conducted under controlled conditions that replicate actual usage scenarios. This approach guarantees accurate assessment of PCBs' ability to withstand NVH-related stressors effectively.
