LED灯珠封装流程是怎样的？

1.LED光源说的5050的意思是指区分LED灯珠的封装料号规格，5050

多想你是俄的唯一 07-27 05:54

长5mm*宽5mm是我们LED封装时区分封装规格的一种常规区分料号型号的一种命名方式。
2.LED光源5050封装料号规格有：SMD5050EMC505
03.led灯带5050是指用5050LED贴片为光源的LED灯具,多是LED灯带的叫法.5050是灯珠型号,指外形大小为5MM*5MM的灯珠贴片.

1.芯片制造；
2.灯珠封装；
3.LED散热与组装；
4.组装驱动器；
5.焊接；
6.老化；
7.测试；
8.安装外罩；
9.QC；
10.标识；
11.包装；
12.入库；

选取好合适大小，发光率，颜色，电压，电流的晶片，LED灯珠封装流程
1：扩晶，采用扩张机将厂商提供的整张LED晶片薄膜均匀扩张，使附着在薄膜表面紧密排列的LED晶粒拉开，便于刺晶。LED灯珠封装流程
2：背胶，将扩好晶的扩晶环放在已刮好银浆层的背胶机面上，背上银浆。点银浆。适用于散装LED芯片。采用点胶机将适量的银浆点在PCB印刷线路板上。LED灯珠封装流程
3：固晶，将备好银浆的扩晶环放入刺晶架中，由操作员在显微镜下将LED晶片用刺晶笔刺在PCB印刷线路板上。LED灯珠封装流程
4：定晶，将刺好晶的PCB印刷线路板放入热循环烘箱中恒温静置一段时间，待银浆固化后取出(不可久置，不然LED芯片镀层会烤黄，即氧化，给邦定造成困难)。假如有LED芯片邦定，则需要以上几个步骤；假如只有IC芯片邦定则取消以上步骤。

也要看灯珠型号的，优欢LED洗墙灯国产灯珠在100以内
