The microphone under test must be discharged between each ESD exposure without ground.

(contact:±8Kv, air:±15Kv)There is no interference in operation after 10 times exposure.

9.焊接要求(Regarding the Soldering operation)

每个驻极体电容传声器在其麦克风上都有一个FET,这种FET在过热和电流撞击时易损坏，所以对于焊接应遵

循以下操作：

－要求使用25W-35W烙铁，并保持320±10℃的温度范围．

－在每一个端的焊接应在2秒内完成，以防过热．

－禁止单体麦克风焊接．（否则会影响驻极体电容传声器的灵敏度）

－最理想的散热装置按以下设计.

Every ECM contains a FET with microphone body.

This FET easy to damageable from excessive heat andelectrical shock. Proper attention for the soldering work is

required same as followings.

－Recommend to use 25W-35W ceramic soldering iron and apply 320±10℃ temperature range

－Soldering should be accomplished within 2 seconds at each terminal so as not to be overheated.

－Do not make a cavity at the surface of lead lump on the PCB. wiring board.

(Opened cavity will influence to the sensitivity of ECM)

－Optimal design for heat sink pad is same as below.
