I'll answer the easy part. If you put low temperature trays in the oven at 120C, they will warp and partially melt. I have seen it more often with reels of LEDs. Someone is told to bake them before use so the put them in the batch oven and the next

Hello, we use an oven to dry our MSL components after the floor lifes expires. The oven works at 40°C / 0.1% RH. The plan is to upgrade the oven from 40°C to 60°C to shorten the duration of the process. I have found a number of articles mentioning

You can have a dry cabinet with or without heater. They use desiccants to take the humidity out from the parts. As you can imagine it will be a lengthy process. The ones with heater can do 40C, which will be preferred for plastic and paper tapes. I w

I agree with Evtimov that sticking with the J-Std-033 is preferable to creating your own procedure at a different temp, especially if you need to pass an audit since the auditors will compare your process to the J-Std. My understanding is that oxida

KA, Joshua makes a good point. A wave solder fixture will allow you to process your double-sided boards without having to add the epoxy step. The one time fixed cost of a fixture is quickly offset by the time that you save by not gluing your SMT.

Sure KA, it's done every day. Be sure that the components to be used on the bottom can take the maximum heat of the wave and the delta T of entering the wave. Depending how complex the bottom side is you will get better results with attention paid

If I understand what you're saying, you are reaching reflow temp's on the top side while soldering bottom side components. You might want to run a glass gauge plate over the wave and make sure your contact pattern isn't too large. If your PCB is in c
