Current IssueFueling the Workforce Pipeline
We take a hard look at fueling the workforce pipeline, specifically at the early introduction of manufacturing concepts and business to young people in this issue of PCB007 Magazine.
Inner Layer Precision & Yields
In this issue, we examine the critical nature of building precisions into your inner layers and assessing their pass/fail status as early as possible. Whether it’s using automation to cut down on handling issues, identifying defects earlier, or replacing an old line...
Engineering Economics
The real cost to manufacture a PCB encompasses everything that goes into making the product: the materials and other value-added supplies, machine and personnel costs, and most importantly, your quality. A hard look at real costs seems wholly appropriate.

iNEMI LTS Tech Topic Series: Electromigration in Tin-Bismuth Planar Solder Joints
October 10, 2023 | iNEMIEstimated reading time: 1 minute
iNEMI is launching a series of webinars focused on low temperature solder (LTS). This first webinar in the series will share information from Phase 1 of iNEMI’s Electromigration in SnBi Solder for Second-Level Interconnect project, which is determining the effects of joint height, temperature, current density and PCB finishes on reliability over a product’s life.
The low melting temperature (138°C) of SnBi alloys make it attractive for assembling high-density microelectronic packaging, which is prone to warpage. However, bismuth (Bi) has a high propensity for electromigration and segregation at the anode under high current density conditions, leading to potentially brittle solder joints with high electrical resistance with time in field.
The Phase 1 project team used a planar geometry solder joint test vehicle to study electromigration in low temperature solders such as SnBi. The novelty of their approach is that the planar solder joints bridging copper traces on printed circuit boards allow the metallurgical and electromigration phenomena to be directly and non-destructively observed while monitoring the resistance changes in the solder joints. This webinar will share the team’s observations and analysis of experiment results plus talk about next steps.
