The product follows the reflow temperature curve to test its reflow thermo stability. Lead pads shall be soldered onto the pc board and the force of 9.8 N (1.0 kg) shall be 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 is to be dropped from a height of 75 cm onto a 40 mm thick wooden board 3 times in 3 axis (X, Y, Z) for a total of 9 drops. Evaluation Standard 95% surface of lead pads must be covered with fresh solder. No in interference in operation. Test Condition The part will be subjected to +85°C for 96 hours. The part will be subjected to -40°C for 96 hours The part will be subjected to 10 cycles. One cycle will consist of: Evaluation Standard No damage or cutting off. After the test, the part shall meet specifications without any damage to the appearance and the SPL should be within ±10 dBA of the initial SPL.
