近日有朋友拿来Epo-Tek 353ND的空产品罐，找我了解此款产品的使用及国产化的情况，最早期接触到光纤方面用胶时就是听说的此款型号，后来通过和国内一些光纤厂商的沟通陆续了解了NTT等一些品牌，详情可参看之前写过的《关于光纤及光学器件封装用胶水初探》，不过这两家产品的用途点是完全不一样的。后来咨询了国内之前做此类产品的厂家，索取了一些样品，打算让朋友去尝试一下。 其实这类产品价格貌似也比较透明，在网上就找到了一个公开的报价页面（点击查看之），与实际了解到的价格相差也不是很离谱。今天有空又在Epoxy Technology, Inc.的官网上找到了TDS和MSDS资料，感兴趣的朋友可以下载参考一下：

Product Description:
EPO-TEK® 353ND is a two component, high temperature epoxy designed for semiconductor, hybrid, fiber optic, and medical applications. It is one of the most popular EPO-TEK® brand products, and is known throughout the world for its performance and reliability. Also available in a single component frozen syringe.
EPO-TEK® 353ND Advantages & Application Notes:
 Reasonable pot-life that allows for low temperature curing to be realized. It has an amber color change upon cure.
 Passes NASA low outgassing standard ASTM E595 with proper cure - http://outgassing.nasa.gov/
 Semiconductor suggested applications: wafer-wafer bonding of CSP; fabrication of MEMs devices; flip chip underfill.
 Hybrid suggested applications: providing near hermetic seals and UHV seals in sensor devices, resisting high temperature packaging
o Down-Hole petrochemical fiber optic sensors, resisting >200°C field conditions
 Fiber optic adhesive designed to meet Telecordia 1221 - suggested applications:
o Sealing fiber into ferrules, transmitting light in the optical pathway from 800- 1550 nm range
o Fiber component packaging; adhesive for active alignment of optics, environmental seal of opto-package, V-groove arrays
 Medical suggested applications:
o Potting fiber optic bundles into ferrules for light guides and endoscopes; capable of resisting several sterilization techniques including ETO, gamma, ION beam, H202 plasma, and >200 autoclave steam cycles; excellent adhesion to surfaces including SST, diamond, titanium, brass, ceramics, glass and most plastics.
o Certified to USP Class VI Biocompatiblility Standards for medical implants; adhesive for catheter devices including stents and guide wires
 Electronics Assembly suggested applications:
o Used as dielectric layer in the fabrication of capacitors; laminating PZT ferroelectrics found in ultrasound or ink-jetting devices
o Impregnating and insulating copper coil windings in motors and inductor coils. Bonding ferrite cores and magnets.
o Structural grade epoxy found in hard-disk drive devices; bonding of SST metals, kapton, and magnets
