Application of the Flowers of Sulfur Test to the Turbini Corrosion Coupon
Bibliographic record
Abstract
ABSTRACT With increasing airborne pollution levels in several parts of the world and decreasing spacing of components in electronic assemblies and lead free soldering, the corrosive effects of the pollutants on modern electronics is becoming more apparent. The standard test for this has been the mixed flowing gas test (MFG). This is an expensive, complicated and rare test. There are probably fewer than 25 of these units in all of North America. A simpler test is the flowers of sulfur test (FoS) which subjects the test coupons to the vapor of pure sulfur. This is a test that can be safely performed with a minimum of equipment. In the present work FoS is applied to the Turbini coupon, an adaptation of the Bono coupon. The effects of the sulfur chemicals on coupons of true bare copper and other coupons coated with OSP subjected to different conditions of temperature and humidity are detailed in this paper. Examination of the coupons is done by cross-sectioning and SEM/EDX.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
