| Looking at the full convection reflow oven market, I see two segments, high mass heater ovens (i.e. Electrovert Omniflow,...), and low mass heater ovens (i.e. Heller,...) | Did some of you guys did some testing on both types and what were your find

Thermal mass is the ability of a material to absorb heat energy. * A lot of heat energy is required to change the temperature of high density areas, like a ground plane. They are therefore said to have high thermal mass. * Light weight areas, such as

What is definition of thermal mass?

emmanuel : i agree with Dave , it's easy to have blind hole on the bottom side , of course in this case you'll lose some thermal efficiency ;the second solution is to put on the bottom side between the board and your heatsink a soft thermal interfac

Thanks for all of your suggestions. I ended up borrowing a Pace Worldwide PH100 Preheater, which worked like a charm. I'm in the process of purchasing one for our own shop. I had to place the aluminum pcb directly onto the PH100's ceramic heating pla

The kester better known as KY'd Sn/Cu has more copper intermetallic growth over time, dissolves copper from the board faster so repairing and touchup can damage board. Bridges more than SN100c. Does not thermal cycle well. Has shrink cracks that can

I must be missing something.....why can't you simply attach thermocouples, profile the assembly, and adjust your zones as required to reach the parameters required by your paste and component specifications? Is there a restriction on that process fo

You must thermally profile your circuit boards with a data-logger and thermocouples. Just putting in oven set points and looking at solder joints is not enough. Reference IPC-7530

Get in touch with your paste manufacturer. They should have a data base of different oven types/zones, and can give you "baseline" settings for a medium thermal density board that has been proven to work well with their paste. After that, it sounds

Very interesting question you have here. Guess where all the mass production id? -In China. Brazil is still a market for machines. Besides some automotive, US is not really doing mass production any more.
