【技术】一体成型电感的线材选型以及绕线工艺焊接工艺介绍
线材是一体成型电感制备重要的原材料之一,而线圈的绕线工艺又是一体成型电感前道工艺里最重要的环节之一,可以说绕线工艺的好坏直接决定了一家工厂在一体成型电感上能做到多小,多薄的体积;选用合适的线材对其制备产生重要影响,下面就一体成型电感线材的选型向大家做简单介绍。
线材是一体成型电感三大核心原材料之一;线材绕制成的线圈是电感产生电学性能的关键要素之一;是产品重要的填充组成部分。
常见一体成型电感的使用范围按照AEC-Q200无源器件应力测试认证的划分标准如表1:
表1 AEC-Q200无源器件应力测试认证温度表
通过表1可知,电感常见的使用温度范围有两类:-40~+125℃、-50~+150℃(包含自身发热);对所需线材提出了不同温度和特性要求。
漆包铜线是一体成型电感常用线材;根据目前常用主流的线材分类可见下表2:一体成型电感常用线材是漆包圆、扁平铜线。圆铜线,绕法灵活多变、简单易型,结构牢固等优势被优先选用;扁平线,绕法单一、填充率高,寄生电容小、特性优势明显等常用于高性能电感器设计。
表2 漆包线分类表
通过对一体成型线材选用的实践,现总结主要影响因素如下。
产品线材的选型,会影响绕线制程、线圈厚度、产品外观、电学特性等,使用时可根据客户的需求进行合适的考量,如产品的应用电压超过48V;需重点考虑漆皮厚度、耐压、耐磨特性;如产品的尺寸相对较小,重点考虑漆皮自粘性以及接著方式;如要求制程效率高的热风枪;需考虑接著方式、横截面积及漆皮厚度;耐高温要求如-50~150℃,尽量选用200、220级线材,如应用到航空航天等复杂环境下的电感,线材优先选用240级;如线材直接做电极,优先选用可焊性。选用的时候,注意特性、尺寸及制程的密切关联性。
绕线工艺和焊接工艺,在一定的程度上觉得了一体成型电感能达到怎样的工艺水准和良率,长江微电当前在超小型化,超薄化的一体成型电感的线圈工艺,采用了全新的焊接工艺,自研了绕线机和碰焊机,可以解决超小超薄线径的焊接问题,彻底解决了行业线圈的虚焊、炸焊等现象,从而彻底解决了长期困扰行业的线圈虚焊炸焊导致的良率问题,也先行开发了超薄型(厚度达1.0mm)的一体成型电感。
长江微电当前所生产的一体成型电感有:FXL系列,广泛应用于工业领域;FAUL\FAU系列,广泛应用于汽车电子,FWP\FXLB等小型化系列,广泛应用于手持智能设备如、手机、手环、电子手表、SSD固态硬盘、IOT等物联网模块等。
