The buzzer follows the reflow temperature curve to test its reflow thermo stability. 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. evaluation standard 95% of the lead pad surfaces must be covered with fresh solder (except the edge of the terminal). No interference in operation. soldering heat resistance terminal mechanical strength 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. vibration drop test 20050 SW 112th Ave. Tualatin, Oregon 97062 phone 503.612.2300 fax 503.612.2383 phone fax rev. page date A 3 of 5 01/07/2008 PART NUMBER: CT-1205 DESCRIPTION: magnetic buzzer ENVIRONMENT TEST item high temp. test low temp. test thermal shock test condition After being placed in a chamber at +85°C for 96 hours.
