Test Engineer (PCBA)

Role & responsibilities

Test Engineering & Optimization

• Develop, validate, and maintain ICT (InCircuit Test), FCT (Functional Circuit Test), and Boundary Scan (BScan/JTAG) test programs for PCBA.
• Define optimal test strategies combining ICT, BScan, and FCT to maximize coverage and minimize escapes.
• Support test fixture development, probe optimization, and overall test coverage improvement.
• Optimize test programs to improve First Pass Yield (FPY) while reducing false failures and retest rates.

Statistical Analysis & Drift Monitoring

• Monitor component parameter drift and behavioral changes over time using production and test data.
• Perform histogram analysis, distribution studies, trend monitoring, Cp/Cpk, and statistical correlation analysis.
• Identify shifts caused by component aging, supplier variation, and manufacturing process drift.
• Refine ICT/FCT/BScan test limits, algorithms, and guardbands based on statistical evidence.
• Establish datadriven criteria to clearly differentiate normal process variation from true failure conditions.

Failure Analysis & Root Cause

• Perform indepth electrical and functional failure analysis on PCBA defects.
• Debug issues related to components, solder joints, assembly process, design margins, and test coverage gaps.
• Apply systematic root cause methodologies such as 5Why, Fishbone, Pareto, and correlation analysis.
• Drive corrective and preventive actions with design, process, quality, and supplier teams.

Automation & Programming

• Develop and enhance test programs, analysis scripts, and automation tools using:
• VB.NET
• Python
• C++
• Automate test data collection, report generation, statistical analysis, and failure trend monitoring.
• Support integration of test systems with MES, databases, and cloud platforms where applicable.

Electronics & Debug

• Strong foundation in analog and digital electronics.
• Ability to read and interpret schematics, layouts, BOMs, and test specifications.
• Handson experience debugging PCBAlevel electrical and functional issues.

PCBA Assembly Process Knowledge

• Strong understanding of SMT, THT, reflow soldering, wave soldering, and typical assembly defects.
• Ability to correlate assembly process variation with test behavior and failures.

Preferred candidate profile

• Bachelors degree in Electronics Engineering, or related field with 2+ years of experience in PCBA trsting..
• Strong proficiency in advanced statistical analysis
• Proficiency in programming languages and software tools used for test development (e.g., LabVIEW, VB.net, Python, C/C++).
• Knowledge of Boundary scan technology.
• Knowledge on microcontrollers and its basics.
• Proven experience in in-circuit testing and electronic test engineering.
• Familiarity with in-circuit testing equipment, such as flying probe testers and bed-of-nails testers.
• Strong understanding of electronic components, circuit board design, and manufacturing processes.
• Knowledge on board level programming and communication protocols (JTAG, SPI, Serial – USB and RS232, Ethernet, GPIB)
• Excellent problem-solving skills and attention to detail.
• Effective communication and collaboration abilities.
• Proven team player, high on collaboration with partners.
