1) raising the maximum reflow temperature high enough to reflow the material thoroughly, 2) preventing vibration of assembly during and immediately after reflow, 3) accelerating the cool down rate after reflow , and 4) checking the alloy analysis for high levels of contaminants.

What are the six types of bad solder connections?
Six types of bad solder connections include a cold joint with insufficient wetting (Pin) or insufficient wetting (Pad), a disturbed joint, an overheated joint, too much solder, or not enough solder.
What keeps a solder joint clean?
Sand paper or steel wool to clean it and flux to clean the oil or other surface contaminants so that the solder will stick.
Can silver solder be used on 14k white gold?
Yes, silver solder can be used on any color of gold---however, the joint will be white and will tarnish more rapidly.
Is soft solder a good conductor of electricity?
Yes: flux core solder is. No: acid core solder is not.
Does solder bend?
Yes. solder is very flexible and soft.
What should be prevented prior to the solder cooling in order to to get a good shiny solder joint?
Movement. The components being soldered need to be fixed, stable, and clean to allow the solder joint to solidify and adhere properly. Movement of components will cause a 'dry' joint which will be electrically unreliable and have a dull appearance.

What is a poor solder joint called?
A dry joint
What is a bad solder joint?
A soldered joint that was done poorly.
What type of solution is solder?
Yes. It is a solution indeed
Do soldered joints have too high a resistance?
Soldered joints will have a higher resistance if the joint is not a clean solder joint. Badly soldered joints are classed as a cold solder joint. <<>> ...for what? Application matters here.
What are the characteristics of a good solder connection?
The surface of the solder on the connection you are soldering should be bright and shiny. A cold solder joint will not be shiny, it will have a crinkly look about it. In some cases the joint can be wiggled and it will come apart.
Why solder is not a true solid solution?
Solder is not a true solid because solder is a liquid but during the art of solding it changes into a solid.
What am I doing wrong when I can't get the solder to stick when soldering a copper pipe?
Not cleaning the pipe or joint enough, not using flux, or not heating the pipe or joint enough. You use the blue tip of the flame on the joint and the capillary action sucks the solder into the joint. You have to clean the pipe with sandpaper or steel wool, the joints with a fitting brush on the inside, and use a proper flux and solder.
Why is using much solder problematic with fine jewelry?
use the smallest amount of solder necessary to make a good joint.
Properly made and cooled solder joint will have the solder?
well wetted round both conductors, and will appear shiny and smooth.
What is cold flow?
It is a term used when soldering with a soldering iron. It means that the solder is not completely up to temperature to make a proper joint. A good solder joint is very silvery in colour and shines when it is done right.
