We have been using nitrogen in our reflow ovens for many years to reduce oxidation on our solder joints. Management is concerned about the high cost of nitrogen and have suggested we use hydrogen instead. I'm not sure if this is a good idea, but we

As you know there will be a lot of residues(such as rosin) left especialy on the peak zone and cooling zone of reflow oven after reflow soldering in a time. who use one kind of effective liquor or effective method to clean the residues ?

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?

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

Reach out to me Don, I build this type of tooling on a daily basis. these are known as Pallet carrier trays, custom Matrix trays, etc, etc... Very common in this day & age. ETM SOLDER PALLET DUDE.

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

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

In our reflow oven it has pins which move at the predetermined speed to move the pcb through the various zones in the oven. The forward row of pins is fixed along the front of the oven. The rear set of pins is adjustable per the width of the pcb. We

Today's regular Sn-Pb paste chemistries are designed to run at higher peak temperatures ensuring that your lead-free alloys will coalesce with your regular Sn-Pb solder. That being said, it is do-able to solder both types in one oven. Generally, wit
