Fu gave her overview of the last eight years with iNEMI along with her opinion of what the most significant changes have been, globally and for the Asia market in particular. She predicts that in the future, the PCB will probably adopt optical architectures instead of copper, because using copper for the trace means that the land space and the property will not satisfy the future high-speed data transport rate.
Final Test Solution of WLCSP Devices
The common back-end process flow for mobile WLCSP devices is a single- or dual-insertion test at wafer probe. Since there is no final test prior to tape and reel, this equipment typically needs to provide a 5-side device inspection to identify potential device damage from sawing. The inspection efforts are quite demanding, with defect recognition requirements in the range of only 10 to only 20 microns, resulting in frequent time and cost intense human interaction and support requirements.

Reliability Assessment of No-clean and Water-soluble Solder Pastes, Part II
Twenty-five years ago, solder paste residues had to be cleaned after reflow due to their corrosive nature: two ways of cleaning were available, either with solvent or by using water, with or without detergent. Now, the assembly world is mainly no-clean: paste formulation is safer in terms of chemical reliability and process costs are reduced without cleaning.
Reflow Profiling on the Electrical Reliability of No-Clean Solder Paste Flux Residues
Optimization of a reflow profile often focuses on mitigating defects such as voiding, tombstoning, graping, and slumping/bridging. But little thought is given to the reflow profile’s effect on the electrical reliability of the no-clean flux residue. Because of the wide variation in size and thermal density of SMT components and PCBs, achieving a reflow profile that equally heats the entire assembly can be challenging and often impossible.

Assembly and the Quest for Solder Alloy-Free Electronics (SAFE)
"As first brush, the title's suggestion that solder can be eliminated from the assembly process may appear absurd. Everyone related in any way to this industry knows solder is the universally accepted way of connecting components to printed circuits in electronic assemblies. Thus, the fact that many knowledgeable people in the industry might scoff at the notion solder can be eliminated comes both without surprise and a certain amount of resignation," writes Joe Fjelstad.
