Surface mounting condition 5.1 Reflow soldering Recommendable reflow soldering condition is as follows. Note: (1) In automated mounting of the SMD sound transducers on PCB, any bending, expanding and pulling forces or shocks against the SMD sound transducers shall be kept minimum to prevent them from electrical failures and mechanical damages of the devices. (2) In the reflow soldering, too high soldering temperatures and too large temperature Gradient such as rapid heating or cooling may cause electrical failures and mechanical damages of the devices. 5.2 Soldering pattern 江苏华能电子有限公司 JIANG SU HUANENG ELECTRONICS CO.,LTD Specification for Electro-Magnetic Buzzer (SMD Type) Model No.: MLT-1230 Part No. Chenbao Industrial Park, Chenbao Town, Xinghua,Taizhou City,China.
