Typical Frequency Response Curve FUET-1760 泰州福声电子科技有限公司-----电声产品专业制造商 FUSHENG ELECTRONICS------Acoustic Components Professional Manufacturer 5.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 FUET-1760 泰州福声电子科技有限公司-----电声产品专业制造商 FUSHENG ELECTRONICS------Acoustic Components Professional Manufacturer 6.
