Descripción
IC_Tester es un sistema de instrumentación electrónica diseñado para realizar pruebas automatizadas en circuitos integrados de la serie 74xx. Permite verificar el funcionamiento de compuertas lógicas mediante generación de señales digitales y análisis de respuestas.
El sistema está pensado como un prototipo funcional de bajo costo para validación de ICs.
Características principales
- Prueba automática de compuertas lógicas (PASS / FAIL)
- Generación de señales digitales con microcontrolador
- Comparación contra tablas de verdad
- Monitoreo de corriente en tiempo real (INA219)
- Detección de ICs dañados (pines defectuosos)
- Interfaz en PC para control y visualización
Arquitectura del sistema
El sistema se compone de:
- Arduino Nano: genera señales de prueba y controla el flujo
- PCB personalizada: integra todos los componentes
- Socket ZIF-14: inserción rápida de ICs
- INA219: medición de corriente vía I2C
- Interfaz en PC: comunicación serial (VISA)
Flujo de operación
- Inserción del IC
- Aplicación de entradas digitales
- Lectura de salidas
- Comparación con valores esperados
- Resultado final: PASS / FAIL
Tecnologías utilizadas
- Arduino
- Visual Studio
- LabVIEW (NI-VISA para comunicación serial)
- Diseño de PCB
Hardware (BOM resumido)
- Arduino Nano
- INA219 Current Sensor
- LM7805 (regulador)
- Socket ZIF-14
- Capacitores y resistencias
- PCB personalizada
Resultados
- ICs funcionales →
RESULT: PASS - ICs dañados →
RESULT: FAIL - El sistema identifica correctamente grupos de compuertas defectuosas

Questions
How big is the PCB CircuitAnalyzer PCB?
It measures 69 × 67.4 mm and has 2 copper layers, 1.6 mm thick.
What parts does the PCB CircuitAnalyzer use?
36 parts. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
Where can I download the PCB CircuitAnalyzer KiCad files?
From the EmiFX/IC_Tester repository on GitHub, at the commit this page was made from: the board is src/pcb/PCB_CircuitAnalyzer/PCB_CircuitAnalyzer.kicad_pcb and its schematic src/pcb/PCB_CircuitAnalyzer/PCB_CircuitAnalyzer.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the PCB CircuitAnalyzer design in my own project?
Its repository states no licence, so its author keeps all rights: ask EmiFX before reusing the design.
