Lead-free or die

 

 
Lead-alloy solder will soon be banned from most electronics sold in Europe. Assemblers and PCB makers are learning how to cope. studied how lead-free solders would work with its surface-mounted components. One study concerned a leadframe finish comprised of four layers of nickel and palladium. TI had previously used a thin layer of lead to protect the underlying pure nickel layer from oxidation. Use of a lead-free finish changed the contact angle of solder. At top is an artist's depiction of an SOIC lead cross section finished with tin-lead. Below is an SOIC finished with nickel-palladium. Both cases use Castin lead-free solder paste. TI says the higher contact angle proved to be only a cosmetic issue and didn't change the mechanical strength or reliability of the joints. An example developed by the National Electronics Manufacturing Center of Excellence depicts the diference in wetting properties of leaded and lead-free solder as defined by contact
