Wave Soldering - Finish and Quality

Finish and Quality

Quality depends on proper temperatures when heating and on properly treated surfaces.

Defect Possible causes Effects
Cracks Mechanical Stress Loss of Conductivity
Cavities Contaminated surface

Lack of flux
Insufficient preheating

 Reduction in strength

Poor conductivity
Wrong solder thickness Wrong solder temperature

Wrong conveyor speed

 Susceptible to stress

Too thin for current load
Undesired bridging between paths
Poor Conductor Contaminated solder Product Failures

Famous quotes containing the words finish and/or quality:

    “To finish a work? To finish a picture? What nonsense! To finish it means to be through with it, to kill it, to rid it of its soul, to give it its final blow ... the coup de grâce for the painter as well as for the picture.”
    —Pablo Picasso (1881–1973)

    “There were never in the world two opinions alike, any more than two hairs or two grains. Their most universal quality is diversity.”
    —Michel de Montaigne (1533–1592)
