| Characteristic | Requirement | |----------------|-------------| | | Circular or square pad, often with a plated through-hole (PTH) for durability | | Size | Typically 1.0 mm – 1.5 mm diameter (for pogo pins); 0.8 mm minimum for manual probes | | Finish | Gold (ENIG) or tin-lead (HASL) – gold preferred for oxidation resistance | | Accessibility | Placed on the bottom (solder side) or top side, but always on a single layer without solder mask over the pad | | Spacing | Minimum 1.27 mm center-to-center to avoid shorts between adjacent test points | | Annotation | Silkscreen label (e.g., "TP_KMGD_3V3", "GND_KMGD") for identification |
Small, gold-plated or solder-masked copper circles on the surface of the board. kmgd test point
The test point operates on the fly.
Why choose KMGD over other types?
First, it is crucial to clarify that "KMGD" is not a generic electrical term but a specific commonly associated with miniature, surface-mount (SMD) test points manufactured by leading connector and interconnect companies, notably Keystone Electronics Corp. (where "K" often hints at Keystone, and "MG" may refer to a product family or material code). First, it is crucial to clarify that "KMGD"
For most mid-to-high volume production, the KMGD offers the best balance of cost ($0.08–$0.20 each in volume), durability, and ease of use. The KMGD test point is a low-profile, surface-mount
The KMGD test point is a low-profile, surface-mount device designed to provide a durable, accessible contact point for oscilloscope probes, alligator clips, or bed-of-nails test fixtures. Unlike traditional through-hole test loops or large turret terminals, the KMGD sits flush on the PCB surface, making it ideal for high-density circuits where vertical space is at a premium.
