Known Good Die
Known Good Die describes a tested integrated circuit (die) , in the microelectronics. The dice (plural) are qualified by the chip manufacturer on a wafer to be error free, before being
IMDS
Description:IMDS stands for "International Material Data System". IMDS (www.mdsystem.com) was developed by automobile manufacturers to collect the composition of the materials&nbs
Layer
Description:Layer (deutsch Lage) stands for a plane of a printed circuit board. Speaking about material, the number of layers is mostly related to the copper layers. But within a PCB layout pro
Outer layers
The outer copper layers / conductive patterns of printed circuit boards are refered as outer layers (named top and bottom). A printed circuit board has one (single-sided PCB) or two (two
Inner layers
Description:The (copper) layers of a multilayer circuit board which are located between the outer layers (top / bottom). Laminates and copper of different thickness can be combined
Ground plane
Description:The ground plane is usually a relatively large area of copper on circuit boards, in multilayer PCBs typically in the inner layers. It serves as electrical ground, shielding o
Netlist
Description:The netlist contains the electrical connections between the components on the circuit board, and is usually held in textual format (see EDIF).In printed circuit board production a
E-Test
The E-test is used for testing the circuit board for short circuits or open connections (compared to the netlist). For the E-test, two methods are common:
