Defect analysis

External observation
  • Observes defective point
  • Identifies nature of defect
SSEM/EDX analysis
  • Evaluates quality of plating
  • Identifies contaminating element
FT-IR analysis
  • Analyzes contaminating element
  • Identifies contaminating substance
Cross section
observation
  • Evaluates IMC
  • Evaluates crystalline structure
  • Observes defect (eg. head-in-pillow, clutch, tombstone)
X-ray analysis
  • Observes voiding
  • Observes head -in-pillow defects
Simulation
  • Simulates wetting behavior
  • Observe warpage of component and board
  • Suggests recommended reflow conditions
Joint strength test
  • Evaluates shear strength
  • Evaluates pull strength
  • Observes breakage mode
Thermal shock test
  • Evaluates joint durability
  • Observes growth of IMC
SIR test
  • Observes electro-migration in thermo-hygrostat
  • Evaluates voltage applied SIR
  • Evaluates drying at normal temp.

Optimization

We provide assistance for you to achieve the best possible performance in the assembly.
Using conditions may vary from customer to customer, from product to product. We will investigate and narrow down the optimal print conditions, reflow profile, etc. according to your unique environment so you can take full advantage of our soldering materials.
