We have a board that uses a solder pad for one of the contacts of a button battery and had no problems when we were washing the boards. We are now using a no-clean flux and find that on a bunch of boards there is a coating of flux covering the pad s

Some no-cleans will pool flux on the top of the solder joint which acts like an insulator. I normally do not paste "contact" pads. You can have your board house HASL them if you need the extra bump on the pad.

I assume that you're talking about wanting to solder to metal tabs that are spot welded to the battery terminal. These tabs are not meant to be soldered. The metal was special selected for welding. In the old days, you could buy plumbing flux at th

Can anyone advise on the risks involved in using a (previously soldered) component, in this case an 'SOIC8', as pick-up area for subsequent pick/place operation of sub-assy to larger motherboard ? The sub-assy in question would be a small outline(25

If the tab is Sn plated, you can solder to it as long as your iron has enough power (watts). If you continue to have trouble then it probably isn't Sn plated.

First, don't exceed the maximum temperature of the battery, say 85*C [I don't know your specifics] Second, don't short the terminals of the battery. Third, the best way to wave solder a battery is: * Insert an insulating tab between the battery an

No we have a battery spring that is soldered directly to a PCB (standard tin plated copper PCB). The Battery spring supplier (and I have no confirmation he makes them or buys them) claims they are tin plated. When trying to solder to them it is very

Hello all. We have been having some problems soldering to what we believe is a nickel plated spring steel battery terminal to a PCB. We have tried scrapping , then tinning, dipping and still have problems. Are there any special fluxes or pre-treats t

thank you so much for the info, wished I would have known previously, however I found the motherboard manual online, and located the Dallas CMOS chip soldered to the board. Found a lot of youtube fixes online. Dremel tool and some soldering, added an

We are doing hand soldering for the 'BATTERY LITHIUM COIN CELL 3V CR 2032 but now we want do the soldering through wave soldering process ,for avoiding the shortckt only one pin will get solder through wave process and other pin will be soldered manu
