Our SEM-EBSD detector is dedicated to the microstructural analysis of crystalline materials, especially metals: solder joints for electronic assemblies and additive manufacturing parts (TA6V, AS7, Inconel, stainless steels…). Alternative analyses, by optical inspection, may be performed : grains revelation after chemical etching grain revelation by chemical etching or under polarized light.


Failure analysis: identification of the metallurgical phenomenon that contributed to a damage (thermomechanical wear, growith of fragile IMC…)

R&D: determination of the physical and metallurgical aging mechanisms (recrystallization / grain growth ; granular rotation ; IMC coalescence ; stress relaxation) and their kinetic, depending on thermal profiles


We mostly analyze electronic solder joints, leadfree ( SAC305, AuSn, SnSb...) or leaded (SnPb, SnPbAg). Beyond these materials, SEM-EBSD is useful on various materials: semiconductors, additive manufacturing metals, ceramics.


SEM-EBSD on electronic solder joints

EBSD maps of a SAC solder joint, after microsection :

Granulometry (grain size & shape)
→ recrystallization & grain growth

Grain orientation & texture (MUD)
→ anisotropy

Précipitates, IMC & phase discrimination
→ coalescence of IMC & phase ratio

Permanent strain (intragranular disorientation)
→ mechanical damage
