Mechanical Shock Drop the resonator randomly onto a concrete floor from the height of 30cm for 3 times. It Http://www.shoulder.cn Page: 3 SHOULDER ELECTRONICS LIMITED shall fulfill the specification requirements. 2). Vibration Subject the resonator to the vibration for 1 hour each in the X.Y. and Z-axes with the amplitude of 1.5 mm, 10 to 55 Hz. It shall fulfill the specification requirements. 3). Resistance To Solder Heat Dip the resonator terminals no closer than 1.5mm into solder bath at 350 ±10℃ for 3± 0.5s Or dip the resonator terminals no closer than 1.5mm into solder bath at 200 +5℃ for 10+1s,then leave the resonator into room condition for 1 hour. It shall meet the specification requirements. 4). Solderability Dip the resonator terminals into the solder bath at 230 +5℃ for 3+0.5s.More than 95% of the terminal surface of the resonator shall be covered with fresh solder. 5).Pulling Test Weight along with the direction of lead without any shock 1kg for 10sec.The resonator shall show no evidence of damage and shall satisfy all the initial electric characteristics. 6). Bending Test Lead shall be subject to withstand against 90º bending at its stem. This operation shall be done toward both directions, and each operation shall take 3sec.The resonator shall show no evidence of damage and shall satisfy all the initial electric characteristics.
