Test point


A test point is a location within an electronic circuit that is used to either monitor the state of the circuitry or to inject test signals. Test points have two primary uses:
Test points can be labelled and may include pins for attachment of alligator clips or may have complete connectors for test clips.
Modern miniature surface-mount electronics often simply have a row of unlabelled, tinned solder pads. The device is placed into a test fixture that holds the device securely, and a special surface-contact connector plate is pressed down onto the solder pads to connect them all as a group.
