One cycle will consist of: evaluation standard The part will be measured after being placed at +25°C for 6 hours. After any tests, the sensitivity should be within ±3dB compared to the initial measurement. MECHANICAL CHARACTERISTICS item test condition soldering heat resistance Soldering iron of 270 ±5°C should be placed on the terminal for 2 ±0.5 seconds. PCB wire pull strength The pull force will be applied to double lead wire: Horizontal 4.9N (0.5kg) for 30 seconds vibration The part will be measured after applying a vibration amplitude of 1.5 mm with 10 to 55 Hz band of vibration frequency to each of the 3 perpendicular directions for 2 hours. drop test The part will be dropped from a height of 1 m onto a 20 mm thick wooden board 3 times in 3 axes (X, Y, Z) for a total of 9 drops. evaluation standard No interference in operation. No damage or cutting off. After any tests, the sensitivity should be within ±3dB compared to the initial measurement.
