2.5.5.5 Stripline Test for Permittivity and Loss Tangent(Dielectric Constant
and Dissipation
Factor) at X-Band
译文:2.1 IPC
IPC-TM-650 测试验方法
以下是对2.1 IPC 的补充:
IPC-TM-650 测试验方法:
2.5.5.5 在X波段下电容率和损耗角正切(介电常数和损耗因数)的带状线测试验
原文:3.8.3.1 Laminate Visual Properties
Replace the paragraph with the following:
The specimen shall be tested in accordance with Table 3-1for laminates.
Unless otherwise specified, the working area of the specimen shall be examined
with normal or corrected20/20 (also termed 6/6 or 1.0) vision. The worst
50mm x 50 mm [1.97 in x 1.97 in] shall be examined at 10X magnification.
Visual inspection may be carried out under ambient temperature and humidity
conditions.
The specimen shall be tested in accordance with Table 3-2 for prepregs.
Prepreg visual inspection is conducted with normal or corrected 20/20 (also
termed 6/6 or 1.0) vision.
Conductive anodic filament (CAF) growth resistance is recognized as a significant
material attribute. IPC-9691, a CAF user’s guideline, provides information
about CAF and how the test method should be utilized. Requirements for
CAF will be considered as a specification sheet element at such time that
by using TM 2.6.25 the performance level requirements are developed. Until
then, the performance level requirements shall be as agreed upon between
user and supplier.
翻译为试验:理由是:
陈培良:查GB/T 20000.1—2002《标准化工作指南 第1部分:标准化和相关活动的通用词汇》的2.13.1
test 为“试验”,2.13.1 testing 为“测试”,2.13.2 test method
为“试验方法”。因此,不赞成将test译为“测试”。
GB/T 20000.1—2002《标准化工作指南 第1部分:标准化和相关活动的通用词汇》是修改采用ISO/IEC指南2:1996《标准化和相关活动的通用词汇》(ISO/IEC
Guide2:1996, Standardization and related activities - General vocabulary,
MOD)的。本部分由中国标准研究中心提出,由国家标准化管理委员会标准化原理与方法直属工作组(CSBTS/WG3)归口。本部分起草单位:中国标准研究中心、中国合格评定国家认可中心、中国电子技术标准化研究所。
