Hi Everyone Does anyone has any insight regarding the void formation in the solderbumps during wafer bumping by electroplating. Someone told me that it could be mainly coz of the alloy concentration being incorrect. Any suggestions, corrective action

Heller Industries announced today that they have entered into a joint development agreement with International Business Machines Corporation (NYSE: IBM), to collaborate on the development of fluxless mass reflow furnace equipment and process for high volume manufacturing. The fluxless process utilizes gas phase formic acid to replace standard fluxing agents, and eliminates the need for pre-reflow fluxing and post-reflow flux cleanup steps.

Heterogeneous integration has become an important performance enabler as high-performance computing (HPC) demands continue to rise. The focus to enable heterogeneous integration scaling is to push interconnect density limit with increased bandwidth and improved power efficiency. Many different advanced packaging architectures have been deployed to increase I/O wire / area density for higher data bandwidth requirements, and to enable more effective die disaggregation. Embedded Multi-die Interconnect Bridge (EMIB) technology is an advanced, cost-effective approach to in-package high density interconnect of heterogeneous chips, providing high density I/O, and controlled electrical interconnect paths between multiple dice in a package. In emerging architectures, it is required to scale down the EMIB die bump pitch in order to further increase the die-to-die (D2D) communication bandwidth. Aa a result, bump pitch scaling poses significant challenges in the plated solder bump reflow process, e.g., bump height / coplanarity control, solder wicking control, and bump void control. It's crucial to ensure a high-quality solder bump reflow process to meet the final product reliability requirements. In this paper, a combined formic acid based fluxless and vacuum assisted reflow process is developed for fine pitch plated solder bumping application. A high-volume production (HVM) ready tool has been developed for this process.

Traditionally most flip chips were designed with large bumps on a coarse pitch. However, as the trend towards smaller, more compact assemblies continues the sizes of semiconductor packages are forced to stay in line. New designs are incorporating smaller bump diameters on increasingly aggressive pitches, and in many cases decreasing the total IO count. With fewer and smaller bumps to distribute the load of the placement force it is becoming increasingly vital for equipment manufacturers to meet the challenge in offering low force placement solutions. One such solution will be presented in the following discussion. Also presented will be ways to minimize the initial impact spike that flip chips experience upon placement.
