SN100C Features & Benefits

Why Use SN100C?

Features and Benefits

 

Metallurgical

SN100C is the only Pb-free solder that, like Sn-37pb, behaves like a eutectic:

                        • Sharp melting point
                          • High fluidity
                            • Fillets have bright smooth surface similar in appearance to Sn63-37Pb
                              • No shrinkage cracks
                                • Good performance in wave soldering
                                  • Ni stabilizes the Cu6Sn5 inter-metallic for greater reliability

                Appearance of SN100C matches that of Sn63-Pb37

                The SN100C Advantages

                The Ni in SN100C incorporates in the inter-metallic Cu-Sn stabilizing to room temperature the close-packed hexagonal form of this phase so that the inter-facial layer does not crack as a result of the volume increase associated with that change. The suppression of growth of the inter-metallic layer is another consequence of the Ni stabilization.

                Resistance to Vibration

                • SN100C outperforms Sn63PB37 and SAC alloys in severe vibration testing

                 

                 

                Impact Resistance of Joints to BGA Packages

                Shear Impact

                One of the main issues facing the IC packaging industry

                 

                Summary
