) cancels out of the equation. This means the "test point" where an object stops depends only on its initial velocity and the coefficient of friction, not how heavy it is. Alternative Technical References
Ideally, all KMGD test points are placed on the bottom of the PCB. This allows the testing fixture to be simpler and less expensive, as it only needs to probe one side. KMGD vs. Traditional Vias kmgd test point
A typical KMGD test point consists of:
A: These are often typos of each other. The correct official prefix is usually KMG (e.g., 5015 KMG). Always verify with the manufacturer’s datasheet. ) cancels out of the equation
To maximize the effectiveness of a KMGD test point, designers must follow specific layout rules: This allows the testing fixture to be simpler
is the board showing (e.g., not charging, not booting, or no USB data)? Do you have access to a multimeter oscilloscope
Standard test points are usually around 0.8mm to 1.0mm in diameter. For high-density boards, "micro-test points" may be used. Spacing (pitch) is critical to prevent the test probes from shorting against adjacent components.
