Dear All,
These are 5 terms which are uncertain this morning, please give us your hand. : )
Thanks and regards

Back-Bared Land 背裸连接盘 22.0071
A land in flexible printed wiring that has a portion of the side normally bonded to the base dielectric material exposed by a clearance hole. (See Figure B-2.)
挠性印制线路中的连接盘,其边缘的一部分通过隔离孔与暴露的绝缘基材料连接。(见图B-2.)
Backdriving 后部驱动 92.0074
An in-circuit testing technique that drives digital circuitry outputs to a given logic level, by supplying pulses of sufficient electrical current magnitude in parallel with the outputs, in order to overdrive the logic state conditions of the next digital device inputs.
提供与输出并行的足够电流量脉冲驱动数字电路输出至给定逻辑电平,以便加速进入下一个逻辑元件输入的逻辑状态条件的一种在线测试技术。
Background (Artwork) 底层(底片) 22.0076
The nonfunctional area of a phototool.
底片上非功能性区域。
Backward Crosstalk 反向串扰 21.1332
Noise induced into a quiet line, as seen at the end of the quiet line that is closest to the signal source, because the quiet line has been placed next to an active line. (See also "Forward Crosstalk.")
在离信号源最近的无噪音导线末端感应进入的噪声,因为它被放置在工作线路的后面。(又见“前向串扰”。)
Balanced Transmission Line 平衡传输线 21.1333
A transmission line that has distributed inductance, capacitance, resistance, and conductance elements that are equally distributed between its conductors.
一种分布着电感、电容、 电阻和电导元件, 在导线之间平衡分布的传输线。
