The reliability of electronics in harsh environments

31 May 2023 Manufacturing / Production Technology, Hardware & Services

Aqueous Technologies is offering a webinar titled ‘The proliferation of Electronics into Harsh Environments and the Effects on Reliability.’

Since the evolution of no-clean soldering processes, many assemblers have enjoyed the cost and time savings a no-clean process affords. The proliferation of electronics into harsh environments has, however, highlighted the well-established link between process residues and electro-chemical migration (ECM) caused failures. Higher operational voltages, increased component densities, assembly miniaturisation, and increased reliability expectations increase the relationship between clean assemblies and long-term reliability.

This webinar will detail the relationship between clean assemblies and reliability, and the reasons a historically successful no-clean process is measurably less successful on modern assemblies, especially when products are installed in harsh environments. Factors that affect circuit assembly residue tolerance will be presented as well as residue mitigation processes.

Real-world examples of residue-related failures from the automotive and communications space will be presented, along with the solutions adopted by the manufacturers. Multiple residue-induced failure mechanisms will be reviewed including ECM, conformal coating adhesion, frequency distortion, corrosion, and cosmetic. Additionally, the relationship with reflow profiles and residues will be presented.

Newly updated IPC cleanliness quantification standards will also be presented to answer the age-old question: “how clean is clean?”.

Date: 13 June 2023

Time: 17:00 SAST

Clearing the Static: Electrostatic Discharge
Actum Manufacturing / Production Technology, Hardware & Services
A cordless ESD (Electrostatic Discharge) wrist strap does not work by grounding the person in the same way as a traditional wired wrist strap. Instead, it works by reducing or balancing the static charge on your body so that you are less likely to discharge electricity into sensitive electronic components.
