In a galaxy not too long ago, people used PWBs with circuitry on only one  
side. These were often cleaned using cleaning equipment fitted with with  
rotating brushes that cleaned just one side of the populated soldered PWA.  Hence, 
if one just soldered on one side and just cleaned one side, then just  tested 
one side. 
 
Yes, it may be old technology, but their may be legacy hardware around that  
still uses such designs.
