MacDermid Alpha Releases Microfab TS-650: Tin Silver Bump Metallization for WLP

Estimated reading time: 1 minute

MacDermid Alpha Electronics Solutions, announces the release of the MICROFAB TS-650 process, a high-speed tin-silver bump metallization for bump, pillar and capping in wafer level packaging. The TS-650 provides a highly smooth and uniform deposit for coplanarity at the package to substrate interface. The lead-free tin-silver top layer applied by the process provides excellent morphology before and after the assembly reflow. Customers combining the TS-650 with MacDermid Alpha‘s market leading copper pillar for FO-WLP technologies will achieve better process consistency and higher production speeds.

Eric Gongora, Director of Strategic Marketing for Semiconductor Solutions, noted, “We are excited to add TS-650 to our MICROFAB family of chemistries. This allows our customers to plate their copper pillar stack with an optimally matched copper, nickel, and tin-silver plating scheme. No supplier offers the comprehensive portfolio of industry leading chemistries, innovative manufacturing processes and collaborative chemistry development—from front end to back end in the electronics supply chain.“
