Lead pads will be soldered onto the PCB, the force of 9.8N (1.0kg) is applied behind the part for 10 seconds. The buzzer 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. The part will be dropped from a height of 75 cm onto a 40 mm thick wooden board 3 times in 3 axes (X, Y, Z) for a total of 9 drops. terminal mechanical strength vibration drop test evaluation standard 95% of the lead pad surfaces must be covered with fresh solder (except the edge of the terminal). No interference in operation. No damage or cutting off. After the test, the part will meet specifications without any damage to its appearance. The SPL should be within ±10dB compared with the initial measurement. 20050 SW 112th Ave. Tualatin, Oregon 97062 phone 503.612.2300 fax 503.612.2383 rev.
