HENKEL HYSOL FP4650&FP4651 TDS技术资料

今日有网友咨询我FP4651这款产品，之前没有接触过，但是从牌号来看应该是属于HYSOL系列的环氧产品，下载了一下TDS资料，果不其然，而且这款FP4651产品官方显示是“Hysol FP4651 is a low viscosity version of FP4650 for a large array of packages.”，所以顺便也下载了FP4650这款产品的资料来看看。从TDS来看FP4650是2002年就推出的一款型号，而FP4651是2011年推出的一款产品。这款产品从用途来看也是属于高可靠性的环氧包封剂，关于HYSOL系列高可靠性环氧包封剂请参看此文《关于汉高乐泰HYSOL FP系列液态封装材料的应用》，或者以HYSOL为关键字在本站搜索可以找出很多相关的产品。这款产品的填料含量达到82%，也不知道是怎样加进去的，呵呵！另外它的CTE只有15ppm左右，几乎达到EMC的水平，也难怪会具有很高的可靠性了。闲话少说，贴出部分FP4651的TDS内容，大家可以下载附件查看PDF文件：

PRODUCT DESCRIPTION

FP4651 provides the following product characteristics:

Technology	Epoxy
Appearance	Black
Product Benefits	• High purity• Self-leveling• Excellent chemical resistance • High thermal stability • Low thermal expansion • Low viscosity
Components	One-component
Filler content , %ignition	82
Cure	Heat cure
Application	Encapsulant
Typical Applications	Cavity-fill and fine wire pitch applications

FP4651 epoxy encapsulant features very low thermal expansion while retaining syringe dispense capabilities. Its low viscosity and 50 micron maximum particle size gives it improved handling properties over FP4650 for fine wire pitch and cavity-fill applications. It is based on FP4450 resin chemistry, therefore exhibiting excellent chemical resistance and thermal stability properties.
