Description
技术领域
本发明涉及一种LED芯片的封装工艺。
背景技术
在LED灯的制作过程中,需要对LED芯片进行封装。封装后的LED芯片有单面(顶面)发光和多面发光等类型,对于多面发光的LED芯片需要对其四侧面和顶面进行荧光胶涂覆,但是同时涂覆五个发光面,在压平固化过程,容易出现荧光粉向四侧底部沉降的情况,导致出光不均,光效弱,底部出现黄边的情况,严重影响产品质量。
发明内容
为克服现有技术的不足,本发明提出一种LED芯片的封装工艺,可改善LED芯片的荧光胶层出现荧光粉沉降的情况。
本发明提出一种LED芯片的封装工艺,包括以下步骤:
S1、提供载体,以及排布在所述载体上的LED芯片的矩阵阵列,相邻的所述LED芯片之间具有间隙;
S2、采用防沉降荧光胶填充所述间隙,所述防沉降荧光胶控制在与LED芯片的顶面平齐的厚度,烘干固化所述防沉降荧光胶;
S3、于所述LED芯片的矩阵阵列上涂覆速干型荧光胶,以覆盖在LED芯片的顶面,烘干固化所述速干型荧光胶;
S4、在固化后的速干型荧光胶上复合AB胶保护膜;
S5、切割所述LED芯片的矩阵阵列,得到LED芯片封装件。
作为本发明的优选方案,步骤S2的烘干固化的条件为100-120℃的温度下,预热0.15-0.20小时,然后升温至125-150℃,烘干固化2.5-3.5小时。
作为本发明的优选方案,步骤S3的烘干固化条件为在138-150℃的温度下,烘干固化0.8-1.5小时。
作为本发明的优选方案,所述烘干固化操作在加热模具内进行,所述加热模具包括上模和下模。
作为本发明的优选方案,步骤S2防沉降荧光胶控制在与LED芯片的顶面平齐的厚度为通过以下操作进行:在LED芯片的矩阵阵列上涂覆所述防沉降荧光胶,通过第一压板压在防沉降荧光胶上使其流动填充所述间隙,且不超过LED芯片的顶面。
作为本发明的优选方案,所述速干型荧光胶涂覆后,通过第二压板压平后再进行固化。
作为本发明的优选方案,所述防沉降荧光胶由85~115重量份的AB胶、76~83重量份的荧光粉、0.3~0.8重量份的防沉降粉、1~3重量份的扩散粉混合制得。
作为本发明的优选方案,所述防沉降粉包括纳米硅酸铝、超细硅酸钙和气相二氧化硅,所述纳米硅酸铝、超细硅酸钙和气相二氧化硅的用量比为1:2:4。
作为本发明的优选方案,所述速干型荧光胶由85~115重量份的AB胶、76~83重量份的荧光粉和150~280重量份的稀释剂混合制得。
作为本发明的优选方案,所述稀释剂为二甲苯。
与现有技术对比,本发明的优异性体现在:
本发明的LED芯片的封装工艺为先在LED芯片的四侧涂覆荧光胶,固化烘干后,再涂覆顶面的荧光胶进行封装,可减少顶侧荧光胶的荧光粉在固化前向侧面转移造成过量加速沉降的情况。且本发明封装LED芯片侧面采用的荧光胶为防沉降荧光胶,由85~115重量份的AB胶、76~83重量份的荧光粉、0.3~0.8重量份的防沉降粉、1~3重量份的扩散粉混合制得;防沉降粉包括纳米硅酸铝、超细硅酸钙和气相二氧化硅,所述纳米硅酸铝、超细硅酸钙和气相二氧化硅的用量比为1:2:4。通过对各种防沉降剂进行粗细级配搭配,并将各个组分的加入比例调整到最佳,能达到稳定的防沉降效果,减少荧光粉向LED芯片底部转移,出现黄边的情况。此外,本发明封装LED芯片顶面采用的是速干型荧光胶,有助于荧光粉均匀分散并快速固化定型,有助于提高出光效率,且烘干过程稀释剂挥发,固化后的膜层不含稀释剂,不影响荧光粉的含量。
