A chip scale package implements solder bars to form a connection between a chip and a trace, formed in a substrate, such as another chip or PCB. Solder bars are formed by depositing one or more solder layers into the socket, or optionally, depositing a base metal layer into the socket ...
扇入式晶圆级封装FIWLP:全称Fan-inWafer-levelpackaging,又称WLCSP(Wafer-levelChipScalePackage),也就是传统的晶圆级封装,切割晶粒在最后进行,适用于低引脚数的集成电路。随着集成电路信号输出的引脚数目的增加,焊锡球的尺寸也就变得越来越严格,PCB对集成电路封装后尺寸以及信号输出接脚位数的调整需求得不到满足,因此衍...

晶圆级晶片尺寸封装(WLCSP,Wafer Level Chip Scale Package)工艺主要采用激光切割法。采用激光切割可以减少剥落和裂纹等现象,从而获得更优质的芯片,但晶圆厚度为100μm以上时,生产率将大打折扣。所以,多用在厚度不到100μm(相对较薄)的晶圆上。激光切割是通过在晶圆的划片槽上施加高能量的激光来切割硅。但使用传统...
