The actual solder joint occurs BETWEEN the part and the pad. Adding more solder on top will add strength slightly, just by being in the way when you pull on it sideways. A weak joint with a weeks worth of solder on it will still be weak. Solder is

We all know that purity of nitrogen is critical for selective soldering. When it comes to wave solder- how much or what percentage reduction in oxygen is enough to make a difference in 1) at least reducing dross buildup and 2) being anble to cut ba

While the only way this thread could look more like a stealth advert is if it has the word 'advertisement' blinking at us, I'll play along. Questions are: * Have you asked the supplier Fantron Technologies [sales@fantron.com] what they suggest? * Wh

Why do you want to increase the strength of the solder connection? Our experience shows that a proper solder connection has more strength than the strength of the pad to the laminate.

Yes, your strength of the joint is in the intermetallic, and not additional solder. Solder ain't like duct tape, where the more you put, the better it'll hold.

I believe you hit the nail on the head. I just needed to hear it from another person. Glue is a good option. I'll give that a try.

Let�s say I want to increase the shear strength of a solder joint. Does a lot of solder around a joint create more strength? Why not just absolutely bury the component lead in solder. My initial thought is that it doesn�t increase strength, but I don

Boomerang, You said you are new to this so, First question. Are the components placed correctly with no offset pre-reflow? If the answer is yes then it's happening in the oven. Most likely cause is pcb design. If the answer is no then you have a pla

Intermetalic Layer (IL). A compound formed at the interface of two different metals, whose atoms have an extremely high natural attraction for each other, so high, that they do not bond to other elements by any other means. Also, intermetalic compo

Hey Bob, Boy, you are lucky to have a laboratory, and now colorful pix!!! The only silver IMC that you will see are: * Ag6Sn, much less likely at 'normal' soldering temperatures * Ag3Sn, much more likely Allowable silver concentration: * Below 2%
