Wave Soldering-Cleaning-Finish and
quality-circuit board pcb
Some types of flux, called "no-clean" fluxes, do not require cleaning; their residues are benign after the soldering process. Typically no-clean fluxes are especially sensitive to process conditions, which may make them undesirable in some applications. Other kinds of flux, however, require a cleaning stage, in which the PCB is washed with solvents and/or deionized water to remove flux residue.
Finish and quality
Quality depends on proper temperatures when heating and on properly treated surfaces.
|Cracks||Mechanical Stress||Loss of Conductivity|
Lack of flux
|Reduction in strength|
|Wrong solder thickness||Wrong solder temperature|
Wrong conveyor speed
|Susceptible to stress|
Too thin for current load
|Poor Conductor||Contaminated solder||Product Failures|
