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

Cure Schedule

Recommended Cure 30 minutes @ 165°C

 

Use suggested cure conditions as general guidelines. Other cure conditions may yield satisfactory results. With all fast cure systems, the minimum required time for cure depends on the rate of heating. Conditions where a hot plate or heat sink is used are optimum for fastest cure. Cure rates depend on the mass of material to be heated and intimate contact with the heat source.

4. Stir with a large spatula to check for lumps.

5. Cold storage will minimize filler settling.

6. Part B may form a crust if exposed to moist air for an extended period of time. Keep in a well sealed container. For best results, do not use Part B which contains this crust caused by moisture contamination.

7. Thorough mechanical mixing of Part A and Part B together is required for best results. Hand mixing alone is not recommended.

 

Not for product specifications

DESCRIPTION

Hysol® FP4322 is a high purity liquid epoxy encapsulant designed for semiconductor encapsulation. It is a high flow material which requires a cavity or flow control barrier to prevent excessive flow. Hysol FP4322 is suitable for encapsulation of bare chips mounted to plastic substrates as well as potting of small hybrid circuit modules. Spot encapsulation of bare chips on ceramic substrates is not suggested in most cases.

TYPICAL APPLICATIONS

Shelf life at room temperature is approximately 2 days. Product may be stored at –40°C for greater than 6 months. Frozen packages must be thawed before use. Warm at room temperature until no longer cool to the touch (normally 20-60 minutes). Do not thaw in an oven or water bath. For best results FP4322 should be dispensed onto a substrate warmed to approximately 90°C. This will help minimize air entrapment under bonding wire.

GENERAL INFORMATION

For safe handling information on this product, consult the Material Safety Data Sheet, (MSDS).

This product is not recommended for use in pure oxygen and/or oxygen rich systems and should not be selected as a sealant for chlorine or their strong oxidizing materials

 

Cure Schedule

Recommended Cure 2-3 hours @ 170°C or

3-6 hours @ 150°C

Alternate Cure 1 hour @ 125°C plus

(Low Stress) 4 hours @ 150°C

(Designed for packages which are effected by high levels of stress.)

A two-step cure will minimize stress and warpage on large substrates. Curing below 140°C is not recommended. User should gel devices immediately after dispensing to prevent moisture degradation of ultimate cure properties. Use suggested cure schedules as general guidelines; other cure schedules may yield satisfactory results.

  Henkel Loctite Hysol FP4322 TDS (22.7 KB, 117 次)

PRODUCT DESCRIPTION

Hysol® OS2800 is a fast curing, water-white epoxy casting system designed specifically for the encapsulation of seven segment displays. This new system will cure rapidly at temperature above 100°C and can be colored by the addition of specific dye concentrates, AC7113 red, AC7044 green and AC7112 yellow. AC7117 is recommended as a standard diffusant for OS2800.

Cure Schedule

(Recommended for optimum properties)

Recommended Cure 4 hours @ 105°C

Note: Larger parts may require 2 hours @ 85°C pre-cure to minimize exotherm. If exotherm temperature exceeds 140°C, severe yellowing will occur. Typical cured properties were determined using the recommended cure schedule. Some differences in properties may occur with the alternate or other cure schedules.
