元器件和BOM基本认识

1、PCBA基本常识1.什么叫BOM：（简单的说就是物料清单）采用计算机辅助企业生产管理，首先要使计算机能够读出企业所制造的产品构成和所有要涉及的物料，为了便于计算机识别，必须把用图示表达的产品结构转化成某种数据格式，这种以数据格式来描述产品结构的文件就是物料清单，即是BOM。它是定义产品结构的技术文件，因此，它又称为产品结构表或产品结构树。在某些工业领域，可能称为“配方”、“要素表”或其它名称。CommentlanufaclurerManufac-Lurer1PartMurriherManufKfairer2Manuf-arQliurer2PartNumberPartDescriptionQua

5、电子器件可分为12个大类，可归纳为真空电子器件和半导体器件两大块。3）电子仪器：是指检测、分析、测试电子产品性能、质量、安全的装置。大体可以概括为电子测量仪器、电子分析仪器和应用仪器三大块，有光学电子仪器、电子元件测量仪器、动态分析仪器等24种细分类。4）电子工业专用设备：是指在电子工业生产中，为某种电子产品的某一工艺过程而专门设计制造的设备，它是根据电子产品分类来进行分类的，如集成电路专用设备、电子元件专用设备。共有十余类UMJVITILUIUjii继电器:变压器:电感:w.1I0插件二极管:集成电路/IC1插件三极管:贴片二极管:贴片三极管:i*itMPw鬥泌寰ihwh,勺nJLt”rtx
