Hi Ju Yong, The PCB are dry in an airseal cabinet(Staging Chamber) before IR Oven. The bubbles show at around body and solder joint area. You mean the moisture will create bubbles ? Able to advice the humidity and temperature that you are using in

WE USE 3 chamber OF Mc-DRY(MODEL NAME). THE MACHINE CAN REMOVE HUMIDITY FROM PARTS IN THE GENERAL PERIPHERAL TEMPERATURE (MAY BE 25-30;CENTIGRADE). AND IT'S CONVENIENT FOR MAN TO PUT OR TAKE OUT COMPANENT FROM CHAMBER BECAUSE THERE IS NO HOT AIR AN

You are correct. For the 70 deg. C drying temperature to be effective, the relative humidity must be as near to zero as possible. A pulling a vacuum on the chamber is an inexprensive and reliable way to accomplish this. Contrary to some claims, our e

Fractured parts that we've seen at reflow in the past are related to trapped moisture in the part, out-gassing at temp, and fracturing the part. I have seen this on ceramic resonators in the past; don't know why this type of part seems prone to this
