Our Solderability Test Systems are designed to provide fast, accurate and 

objective measurement of solderability for components, including SMD and 

printed circuit boards The system’s output results are 

expressed in quantitative 

units 

 capillary wetting forces (nM) and wetting meniscus angle (degrees). The 

results directly correspond to the solder wettability of the specimen. The 

Metronelec solderability systems advance the state of the art of solderability 
testing by eliminating the need to use indirect comparisons or subjective 

operator interpretations. 
 
Meets requirement of all international standards: 

IPC/EIA J-STD 002 1 003  
JEDEC MIL 883 L 

IEC 68-2-69 
IEC 68-2-58
