1、pcba生产工艺流程如下：SMT贴片加工环节：锡膏搅拌→锡膏印刷→SPI→贴装→回流焊接→AOI→返修。DIP插件加工环节：插件→波峰焊接→剪脚→后焊加工→洗板→品检。 2、PCBA是英文Printed Circuit Board Assembly 的简称，也就是说PCB空板经过SMT上件，或经过DIP插件的 ...

元器件成本占 PCBA 总成本的 40%-60%，一个小数点的误差就可能造成万元级损失。在电子产品设计中，精准估算 PCBA 成本是判断 ...

SMT（Surface Mount Technology，表面贴装技术）是现代电子制造中不可或缺的一项技术，而PCB和PCBA则是这项技术的两大核心要素。 那么，什么是PCB和PCBA？它们在SMT中又扮演着怎样的角色？本文将从专业的角度，以简洁、详实的语言，带您一探究竟。 我们来了解PCB。

随着清洁能源的日益兴起，光伏发电系统在全球范围内得到了广泛应用。在光伏发电系统中，光伏逆变器扮演着将光伏组件产生的直流电转换为交流电的重要角色，而PCBA（Printed Circuit Board Assembly，即印刷电路板组装）技术则在这一转换过程中提供了关键的硬件 ...
