Job summary

LONGCHEER TECHNOLOGY (MALAYSIA) SDN. BHD. in Johor seeks an experienced Lead Electrical Failure Analysis engineer to drive root-cause investigations for SiP modules and related products.

You will independently analyze complex failures from R&D pilot builds, mass production, reliability tests and returns. You will work with the PFA team on SEM and FIB analyses, correlate findings with design and packaging, and push corrective actions to improve yield and reliability.

Qualifications

• Minimum three years of hands-on EFA experience in semiconductor packaging/testing, SiP modules or related field.
• Strong understanding of SiP packaging processes and module construction.
• Proven ability to independently investigate and close complex failure cases using EFA techniques.
• Familiar with PFA methods and integrating EFA/PFA findings for root-cause analysis.
• Experience in mass-production yield improvement and systematic failure investigation.
• Strong analytical, problem-solving and cross-functional coordination skills.
• Able to prepare professional FA reports in English and Chinese.
• Capable of supporting customer technical reviews and communicating complex findings clearly.

Responsibilities

• Operate EFA equipment, including oscilloscopes, EMMI, OBIRCH, TDR and I-V/C-V systems.
• Diagnose SiP-related failures such as open/short, leakage, functional and intermittent faults.
• Collaborate with PFA team on SEM, FIB and cross-section analyses.
• Correlate electrical and physical findings to identify root causes affecting design and processes.
• Drive yield improvement by analyzing failure patterns and proposing corrective actions.
• Develop and optimise EFA methodologies, SOPs and failure-case databases.
• Support customer FA audits, quality reviews, and technical discussions.
• Contribute to lab efficiency, capability development and product reliability validation.

Job description

LONGCHEER TECHNOLOGY (MALAYSIA) SDN. BHD. View all jobs

Lead electrical failure analysis for System-in-Package (SiP), wireless and power module products. Manage failure-analysis cases arising from R&D pilot builds, mass-production yield excursions, reliability testing and customer returns. Independently perform failure localization, root-cause analysis, corrective-action verification, FA reporting and case closure.

Key responsibilities

Operate EFA equipment, including oscilloscopes, EMMI, OBIRCH, TDR and I-V/C-V measurement systems

Diagnose SiP-related failures such as open/short circuits, leakage current, functional failures, intermittent faults, solder-joint defects and interconnection failures

Collaborate with the Physical Failure Analysis (PFA) team on SEM, FIB and cross-section analysis

Correlate electrical and physical findings to identify root causes involving product design, component materials, packaging processes and test methods

Drive yield improvement by analysing failure patterns, proposing practical corrective actions and working with Process, PIE, Test and R&D teams

Develop and optimise EFA methodologies, standard operating procedures and failure-case databases

Support customer FA audits, quality reviews, technical discussions and troubleshooting enquiries

Contribute to laboratory efficiency, technical capability development, product reliability validation and quality improvement

About you

Bachelor's degree or above in Microelectronics, Electronic Engineering, Semiconductor Technology, Materials Science, Automation or a related field

Minimum three years of hands-on EFA experience within semiconductor packaging and testing, SiP modules or a related industry

Strong understanding of SiP packaging processes, module construction, basic IC circuitry, FT/WAT testing and common failure mechanisms

Proven ability to independently investigate and close complex failure cases using appropriate EFA techniques

Familiarity with PFA methods and the ability to combine EFA and PFA findings for accurate root-cause determination

Experience in mass-production yield improvement and systematic investigation of batch-related failures

Strong analytical, problem-solving and cross-functional coordination skills

Able to prepare professional FA reports in both English and Chinese

Confident in supporting customer technical reviews and communicating complex findings clearly
