1.1 本规程涉及电子设备内部不连续性、外来材料、缺失部件、卷曲或断裂导线以及空腔、封装材料或电路板中的缺陷焊点的射线照相检查。本实施规程中提出的要求旨在控制射线照相图像的质量和可重复性，而不是用于控制成像电子设备的可接受性或质量。 1.2 本实践中的某些方面可能需要认可的工程组织和供应商之间的协议，或需要认可的工程组织的具体指导。这些项目应在采购订单、合同或检验技术中说明。 具体应用可能需要部分或全部遵守本惯例。与本规程的偏差应在检验计划中列出，并由认可的工程组织和供应商批准。 1.3 本标准并非旨在解决与其使用相关的所有安全问题（如有）。本标准的用户有责任在使用前制定适当的安全、健康和环境实践，并确定监管限制的适用性。 1.4 本国际标准是根据世界贸易组织技术性贸易壁垒（TBT）委员会发布的《关于制定国际标准、指南和建议的原则的决定》中确立的国际公认标准化原则制定的。 ====意义和用途====== 4.1 本规程规定了在电子元件或设备或两者的射线照相检查中建立质量控制的基本最低要求。本文讨论的注意事项包括图像质量指示器（IQI）特征的定义、IQI成像程序和报告。 4.2 本规程的编写是为了在工程图纸、规范或合同中规定。这不是一个详细的操作程序，必须由详细的检查技术/程序进行补充。

1.1 This practice relates to the radiographic examination of electronic devices for internal discontinuities, extraneous material, missing components, crimped or broken wires, and defective solder joints in cavities, in the encapsulating materials, or the boards. Requirements expressed in this practice are intended to control the quality and repeatability of the radiographic images and are not intended for controlling the acceptability or quality of the electronic devices imaged. 1.2 There are areas in this practice that may require agreement between the cognizant engineering organization and the supplier, or specific direction from the cognizant engineering organization. These items should be addressed in the purchase order, contract, or inspection technique. Specific applications may require adherence to this practice in part or in full. Deviations from this practice shall be enumerated in inspection plan and approved by both cognizant engineering organization and the supplier. 1.3 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use. 1.4 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee. ====== Significance And Use ====== 4.1 This practice establishes the basic minimum requirements for establishing quality control in radiographic examination of electronic components or devices, or both. Considerations addressed herein include definition of image quality indicator (IQI) features, procedures for imaging of IQI, and reporting. 4.2 This practice is written so it can be specified on the engineering drawing, specification, or contract. It is not a detailed how-to procedure and must be supplemented by a detailed examination technique/procedure.
