Accurate controlled impedance
measurements require a testing probe with high
resolution, read our paper on
High Resolution
Testing of Complex Printed Wiring Boards
and find out why!!! |

TDR test systems
are regularly used to measure interconnect loss on
PWBs and widely documented. IBC has developed a
simple methodology to determine interconnect loss
in a high volume production environment. Several
studies have been conducted which demonstrate the
ability of this test methodology to discern
various loss values within different structures
and between different materials (see
PWB Production Test Methodology to Determine
Material Loss Properties.pdf). |
