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. No damage or cutting off. Vibration Drop Test 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. Environment Test Item High temp. test Low temp. test Thermal shock 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 Temp./Humidity cycle The part shall be subjected to 10 cycles. One cycle will last for 24 hours and consist of: After the test, the part shall meet specifications without any damage to the appearance or performance and the SPL should be within ±10 dBA of the initial SPL.
