Pros & ConsPros & Cons

- Lead-free solders have a higher melting point requiring higher process temperatures

- Lead-free solders are significantly harder, which can increase the likelihood of cracks instead of plastic deformation, which is typical for lead-containing solders

- Energy consumption

- Costs to upgrade to technology standard


Pros & ConsPros & Cons

+ Health benefits

+Environment

+ Reliability concerns
