Introducing Closed-loop Nitrogen Control To Solder Reflow
Jan 17, 2023 | David Heller
To achieve higher levels of consistency in PCB output, process engineers are able to maintain tighter controls and reduce process-related defects by using closed-loop process controls. At every stage of assembly, from screen printing through placement to reflow, closed-loop systems help control the variable factors that can have adverse effects on the process....

Vacuum Fluxless Reflow Technology for Fine Pitch First Level Interconnect Bumping Applications

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....

Function and Operational Theory of Condenser Tube Flux Collection System
Jan 17, 2023 | Heller Industries
Heller's new Condenser Tube Flux Recovery System is designed to provide more efficient flux collection than earlier Heller flux collection systems; while providing minimal down time for inspection and cleaning. The entire system easily fits within the rear of the top shell of an 1800-EXL oven. The system utilizes a different set of top shell caps specially designed to provide the best serviceability of both the flux collection system and maintenance of the heater zone blower motors....

Are You Ready for Lead Free
Jan 17, 2023 | Marc Peo & Don DeAngelo
Various international market trends drive electronics manufacturers and their mate- rials and equipment suppliers to develop new assembly techniques to reduce the industry's environmental impact. Two pri- mary forces in this drive are the movements to lead-free assembly and ISO 14000 cer- tification. In response to these factors, reflow technology advances are enabling manufacturers to meet or anticipate the new environmental mandates....
