DaveP, once you shut down the oven, the moisture will start and move into the oven unless you can completely seal the oven after you turn it off. Therefore, keep the components into the oven, don't work. However, if the oven is continously on until

Good day, J-STD-033A: 4.1.2.2 Moisture Sensitivity Levels 5-5a For moisture sensitivity Levels 5 and 5a with floor life exposure not greater than 8 hours, a minimum desiccating period of 10X the exposure time is required to dry the SMD packages en

Ian, First, I baked the parts at 125C for 48 hours and check the weight Second, I soaked the parts above 30C and 60% for 96 hours and check the weight Calculate the weight gain, suppose only moisture add to the parts during soaking, say a Third, dry

Hello all, I have been tasked with bringing my company up to spec with J-STD-033, yes lucky me! My question is this: While I was searching the Web for suitable suppliers of dry cabinets I came across a company advertising a humidity control system f

Okay... to follow-up on my scenario. Would it be cheaper to get a resealer with dessicants and humidity indicators or a baking oven, or both. Is there a moisture controlled storage cabinet (ideally 3'x6'x1' or in that vicinity)? Would be interested

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

I used to bake parts before. After I discovered the drying cabinets, that is not a concern anymore. I strongly recommend you to get one of these and try it. It dries them out pretty quick and keeps very low humidity all the time. No heat applied.

Our shop doesn't have a humidity controlled environment. We reflow our SMT board production at the end of the day. That means some boards can soak in 8 hours worth of humidity before reflow with the obvious negative consequences. What has come to mi

A baking oven over 100 C will be at zero humidity. Do you really need to store pcbs/devices at 200 C...this will surely harm some products ? IPC 33B01 allows storage of MSDs in a dry cabinet at less then 5%.....these can operate at room temp or 40 /
