Abstract

This work analyzed the corrosion failure of a printed circuit board (PCB) exposed to atmosphere of the island of Martinique (located in the Caribbean Sea). This island suffered from the stranding of sargassum algae, which decompose and release toxic gases such as hydrogen sulfide (H₂S). The morphology and properties of the corrosion products were determined using visual inspection, Scanning Electron Microscopy (SEM) and energy-dispersive X-ray spectroscopy (EDS). Sulfur species were observed in corrosion products, demonstrating the impact of sargassum stranding on air corrosivity. RFID silver corrosion sensors were installed to study the corrosion rate in Martinique. X-ray diffraction (XRD) analysis of the sensors confirmed the impact of hydrogen sulfide on corrosion.

马尾藻分解产生的H2S对印刷电路板的腐蚀失效分析

本工作分析了一块印刷电路板（PCB）暴露在马提尼克岛（位于加勒比海）大气中的腐蚀失效。这个岛遭受了马尾藻搁浅的痛苦，马尾藻分解并释放出硫化氢（H2S）等有毒气体。采用目视检查、扫描电镜（SEM）和能谱分析（EDS）对腐蚀产物的形貌和性能进行了测定。在腐蚀产物中观察到硫的种类，表明马尾藻搁浅对空气腐蚀性的影响。安装了RFID银腐蚀传感器来研究马提尼克岛的腐蚀速率。传感器的x射线衍射（XRD）分析证实了硫化氢对腐蚀的影响。

期刊介绍： Microelectronics Reliability, is dedicated to disseminating the latest research results and related information on the reliability of microelectronic devices, circuits and systems, from materials, process and manufacturing, to design, testing and operation. The coverage of the journal includes the following topics: measurement, understanding and analysis; evaluation and prediction; modelling and simulation; methodologies and mitigation. Papers which combine reliability with other important areas of microelectronics engineering, such as design, fabrication, integration, testing, and field operation will also be welcome, and practical papers reporting case studies in the field and specific application domains are particularly encouraged. Most accepted papers will be published as Research Papers, describing significant advances and completed work. Papers reviewing important developing topics of general interest may be accepted for publication as Review Papers. Urgent communications of a more preliminary nature and short reports on completed practical work of current interest may be considered for publication as Research Notes. All contributions are subject to peer review by leading experts in the field.
