The amount of times the tin/lead solder can be melted and solidified is unlimited and the heat cycles do not affect the solder characteristics. The only reason for changing the solder pot is when impurities are at or over the maximum levels.

I would second the hot melt glue method. You do have to teach the importance of "more is not always better" and there will be learning curve, but it's a lot better at securing big clunky electrolytics than RTV. It's also a lot cheaper than chipbonder

Does the solder melt when 'hit' with a soldering iron [and maybe a little flux]? If so, what is the appearance of the solder flow? What causes the green tint in the picture you provided?

Good morning, This isn�t very strange. Bottom side components are prone to tombstoning more than topside ones. Try to reduce oven�s bottom heaters temperature slightly to prevent solder paste melting on bottom side. This can help. BR, Pavel

Your best bet would be to browse through you current solder suppliers catalog and pick your alloy. Most of them have a list of alloys and their melting points as well as what form they can be supplied in.

Technically speaking, most likely yes it will work, unless possibly it is a BGA. There are issues surrounding BGA's. Here are some of the general issues: On any type of component, if the Pbfree solder you are using contains bismuth, then the Pb in

I had something similar a while back it looked like fibreglass insulation in my case (was using no clean flux not water based), i took some and melted it with a soldering iron and it reacted like flux. and i tried disolving it with acetone.

Slain, A melting point of 300C would be a little too high for the components and tinny boards. I just heard they will market the watches as Swiss "army" watches which makes them exempt.

Hi, One other thing, and it's weird to be replying to myself, but what's the melting point of tin? Will the wave do that ok? I guess so, if you guys have done it, but just wondering about it. Regards, Grant

Russ, I believe the concern over solders with bismuth in them was that if you did happen to get a little Pb in your solder joint, you could create an alloy that could melt at around 100 degrees C, and that's not all that warm. At least, that's what
