WebSep 15, 2014 · From C4 to micro-bump: Adapting lead free solder electroplating processes to next-gen advanced packaging applications Abstract: SnAg solder is the industry standard for lead-free wafer bumping. WebSolder wettability (SW) of oxidized-nickel (ON) with liquid lead-free solder (LFS) (96.5Sn–3.5Ag) is notably improved by Ar–H2 plasmas from 0 % wetting of nickel substrate oxidized in air gases at 200 °C for 2 h to 100 % wetting of ON substrate treated by Ar–H2 plasmas at certain plasma settings. The SW of ON substrates with LFS is dependent on …

http://www.msed.nist.gov/solder/NIST_LeadfreeSolder_v4.pdf WebThere are many different ways to put solder bumps on the wafer/die as reported in Ref. 60. If one accounts for cost, surface-mount technology (SMT) experience, material availability, and processing flexibility, microball mounting and paste printing are the two best methods to bump lead-free solders on the wafer/die.
WebJCET is experienced in a wide range of wafer bump alloys and processes, including printed bump, ball drop and plated technology with eutectic, lead free and copper pillar alloys. Our wafer bumping offering includes wafer bump and redistribution for 200mm and 300mm wafer sizes for full turnkey advanced flip chip and wafer level packaging solutions. WebJan 1, 2014 · Solder bumping is one of the key technologies for flip chip connection. Flip chip connection has been moving forward to its further downsizing and higher integration with new technologies, such as Cu pillar, micro bump and Through Silicon Via (TSV). Unlike some methods like solder printing and ball mounting, electroplating is a very promising …
