用英文介绍SMT操作流程

用英文介绍SMT操作流程

老外来了解你们的SMT工艺，绝不是要学习如何操作，而是要从你的介绍中获得信心，认为你们可以很好地控制流程和产品质量。所以介绍应包含以下内容：工艺流程（流程图FlowChart）、制程失效模式与对策分析（PFMEA）、控制计划（CP）、作业指导书（WI）、统计过程分析（SPC）。如果这些内容都有英语版本最好，准备在手边，你只要提到我们是这样控制的，然后拿出文档给他们看，行家一看就明白了。

写一个英文小短文介绍 CRT 成像过程

The cathode ray tube (CRT) is a vacuum tube containing an electron gun (a source of electrons) and a fluorescent screen, with internal or external means to accelerate and deflect the electron beam, used to create images in the form of light emitted from the fluorescent screen. The image may represent electrical waveforms (oscilloscope), pictures (television, computer monitor), radar targets and others. CRTs have also been used as memory devices, in which case the visible light emitted from the fluoresecent material (if any) is not intended to have significant meaning to a visual observer (though the visible pattern on the tube face may cryptically represent the stored data).

The CRT uses an evacuated glass envelope which is large, deep (i.e. long from front screen face to rear end), fairly heavy, and relatively fragile. As a matter of safety, the face is typically made of thick lead glass so as to be highly shatter-resistant and to block most X-ray emissions, particularly if the CRT is used in a consumer product.
