STANDARDS
IPC-1782: The New Dawn of Electronics Traceability

Traceability is thought of as expensive, complex, unreliable, incomplete, a threat to business and different for everyone. Can a new standard for electronics overcome those hurdles?
by Michael Ford

COVER STORY
Was RoHS Worth It?

The EU’s Restriction on Hazardous Substances reached its ten-year anniversary in 2016, but not everyone was celebrating. A decade after the controversial mandate to ban lead went into effect, the R&D experts and administrators on the front line of the switch reflect on what was learned.

COATINGS
Conformal Coating Challenges:Detection, Rework and Failure Analysis, Part II

Understanding coating chemistry dictates the removal strategy. Here, the authors investigate the challenges of conformal coating removal and a design of experiments to enable rework and failure analysis. Special cases where conventional detection of the conformal coating fails are also addressed.

PCBA CLEANING
Field Performance of pH Neutral Cleaning Agents, Part II

The second of a two-part series presenting three case studies on material compatibility and field cleaning performance of alternatives to alkaline cleaning agents. Each user had a different paste/flux vehicle and material compatibility constraints.Yet, based on the results, pH neutral cleaning agents can meet stringent cleaning requirements.

PCBA CLEANING
Field Performance of pH neutral Cleaning Agents

Since their introduction, pH neutral formulations have proven to be capable not only of removing these difficult post-reflow residues from complex board geometries, but do so without affecting material compatibility of sensitive components and at low concentration levels. Part one of a series on material compatibility and field cleaning performance of alternatives to alkaline cleaning agents.

IPC Material Declarations: Sufficient for Automotive Electronics?
IMDS and IPC-1752A are different tools for reporting materials data, created by separate industries for different purposes. Suppliers of automotive electronics are obligated to use both, but should they?
