锡焊装置的气氛形成方法和气氛形成装置
摘要：
本发明提供一种可在锡焊装置内形成稳定氧浓度的气氛的气氛形成方法。按特定的比例使空气与N2气混合，形成特定氧浓度的空气/N2混合气体(步骤1)，将该特定氧浓度的空气/N2混合气体定量供给到锡焊装置内(步骤2)。由于将该特定氧浓度的空气/N2混合气体定量供给到锡焊装置内，所以，不使用检测锡焊装置内的氧浓度的设备(氧浓度计)，即可按特定低氧浓度使锡焊装置内的氧浓度稳定地控制。
摘要（英）：

The invention provides an atmosphere forming method for forming the atmosphere having a stable oxygen concentration in a tin soldering device. Air is mixed with N2 according to a determined radio to generate an air/N2 mixture having a special oxygen concentration (step 1); the air/N2 mixture having a special oxygen concentration is supplying to the tin soldering device in a definite amount (step 2). Then the oxygen concentration in the tin soldering device can be stably controlled based on the special lower oxygen concentration without using a detector (oxygen concentration meter) for detecting the oxygen concentration of the soldering device, because of supplying the air/N2 mixture having a special oxygen concentration to the tin soldering device in a definite amount.
