Hello! Don, I heard from SMT factory that the fixture for oven they use is durostone material, I don't if durostone is correct name translated, it is synthetic stone made of carbon fiber sheet. Best Regards Clare PCB Connect China

Since the inductor is electro-magnetic, that means the device is composite of coil and ferrite metal. The inductor inside the reflow oven meets with blower motors which close to the inductor and generate magnetic field. With such conditions, Lawren

I have some large ROHS SMT inductors that are moving during the reflow process. I have tried adding extra solder, gluing and doing both. I don't know what else to try, any suggestions?

We just use scrap PCBs for Oven carriers. You could probably contact your board house and as for just sheets of FR4 to use. I've also used a binder clip at each corner to lift a board off of the mesh belt in a pinch.

Hello! Don, Yes, if the carrier is steel/stainless, it would be very hot when it comes out from oven. I heard that durostone (synthetic stone) carrier can meet your requirement, it can stand high temperature with low thermal transmission. So when it

If the board is just not reaching the temps you need, you could place them in an oven to "preheat" them. When I was building a rather thick board with a copper core I had to do this. Since we were only doing small runs it was feasible, I don't know y

I use BioAct SC-10 and it seems to work pretty well. The best bet is to contact your solder paste manufacturer and ask them for a recommended cleaning solvent for the flux residues... Regards, Justin
