It can be seen that the H-plate configuration has the highest heat transfer for any given test point
. The H-plate also has the highest pressure drop since it has the most restrictive chevron angle.
For ICT, MDA and BST, the typical requirements are as follows: one test point
per net, all test points
on the bottom of the PCB, and maximize test point
The use of laptops, instead of dataloggers, gives technicians the ability to look up any history that is associated with test points
which in turn significantly decreases the time spent trouble-shooting problems.
Efficiency measures the percentage of tests executed correctly--not whether the software being tested passed or failed the test--and is calculated by dividing test points
on condition by total test points
Canceling the limit that there is only one test point
in a region, we propose an adaptive method of test point
This jig is based on a short, coplanar line, with in and out SMA connectors, having a test point
footprint in its center.
The reader must now make the assessment that is critical to any review of test points
: are they representative?
The software should be able to export a DfT report showing all net names with respective test point
x-y locations, which can be of great use to the test engineer when creating a fixture.
* Have a test point
for all electrical nodes, including unused IC pins.
