The Perfect Solder Joint

The perfect solder joint is a wonder to behold, and indicates a proper connection that will give years of sterling service. Since Leads Direct specialises in leads and cables of all types, we will choose a Jack connection as used in instrument leads (used for electric guitars, basses, keyboards, etc.) for our examples.

A quality solder joint uses the mimum amount of solder necessary – no more than that required to to seal the area between the elements. A large ball of solder indicates a poor joint and can actually degrade the quality of the connection. A good joint will look smooth and shiny rather than dull.

This is how a good solder connection should look – clean, shiny, and just the right amount of solder.

 

A bad solder connection – there is too much solder which clearly uneven, and has sharp points in places. The look of this joint suggests that it may have been overheated.

 

 

An even worse solder connection – note the uneven texture, and the flux remaining on the joint.
