Component Specifications

Definition
A Test Point Array is a systematic configuration of exposed conductive pads or pins on an Interface PCB, designed to facilitate electrical testing, debugging, and validation of circuit functionality. It provides accessible contact points for test probes, enabling measurements of voltage, current, signal integrity, and continuity without direct soldering or invasive methods.
Working Principle
The Test Point Array operates by providing low-resistance, stable electrical connections to specific nodes in the circuit. During testing, probes contact these points to measure electrical parameters, allowing verification of design specifications, fault isolation, and performance assessment without disrupting the PCB's operational integrity.
Materials
Copper alloy (e.g., C11000) with surface finish: Electroless Nickel Immersion Gold (ENIG) or Hot Air Solder Leveling (HASL), substrate: FR-4 epoxy laminate.
Technical Parameters
  • Pitch 2.54 mm
  • Diameter 1.0 mm
  • Resistance < 10 mΩ
  • Current Rating 1 A
  • Voltage Rating 50 V
  • Operating Temperature -40°C to 85°C
Standards
ISO 9001, IPC-A-610, IEC 61188-5-2
