Laser and Electrochemical Studies of Metallizations in Electronic Devices.

Abstract

Environmental and corrosion behavior of Pb-Sn electrodeposits was studied by electrochemical polarization techniques and SEM. Experiments with D.I. water containing .001 to .1 MC1(-) showed that for a given deposit, the corrosion rate increases with C1(-) concentration and decreases with deposit thickness in the 2-25 micro range. The mode of corrosion was associated with preferred dissolution of lead. Deposits were also irradiated with Nd-Yag pulse laser at 530mm and 2x10 to the 8th power -2. 10 to the 9th power watt/sq. cm power density and the treated zones were examined. Keywords: Tin, Lead, Electrochemical, Polarization, Laser, Treatment.
