Automated Microsectioning: An Economic Justification
Introduction
Microsectioning has become a standard requirement of printed wiring board (PWB) quality assurance due to the potential for hidden, subsurface defects, and for process control. In recent years, increasing numbers of PWB customers have begun to require certified vendors to perform statistical sampling of their product. Cost reduction initiatives are the driving forces which have shifted this responsibility to the vendor. Many wiring board manufacturers, however, are unprepared for this shift. Their microsectioning capabilities remain manual in nature, and they are poorly equipped to handle the volume of coupon cross-sectioning necessary to meet their customer’s requirements. Often, all that is needed is a small investment in microsectioning automation, but the perceived costs keep many PWB production houses from taking this critical step. In addition, many are fearful that automation will result in loss of jobs. While it is true that automation will free significant amounts of time for workers to focus on other efforts, it does not eliminate the need for operators altogether. This paper offers a look at manual and automated microsectioning of PWB’s, with the purpose of illustrating the time and cost benefits of automation.

标乐先进的制样技术-Mg及其合金制备
镁合金由于其密度小、强度高、弹性模量大、散热好、消震性好、承受冲击载荷能力比铝合金大等特点,现广泛应用于航空航天、汽车、电子产品等领域。管控镁合金质量的重要手段就是金相检测。但镁合金的硬度低,易氧化,制备金相试样时极易出现划痕,机械抛光后的金相试样表面发乌,缺少镜面光泽,光学显微镜下出现腐蚀坑,从而影响金相观察质量。本期文章主要给大家分享镁合金的金相制备方法。
