Test Engineer

Overview

OSI Systems companies have a long history of developing innovative solutions to bring a better quality of life to the world. With more than 30 years of combined experience in the field of optoelectronics our OSI Optoelectronics (OSIO) division is a diversified manufacturer of standard and custom photodiodes and optical sensors for used in aerospace, defense, commercial and medical applications.

We are one of the largest global manufacturers of optoelectronic devices, delivering engineering design support and manufacturing capabilities that include products for use in the defense, aerospace, medical, and industrial markets, among others. We utilize our world-class manufacturing facilities in the U.S., India and Malaysia to continue to put forth excellent engineering solutions aligned with efficient manufacturing to meet high-volume production requirements.

OSI Optoelectronics is seeking a Test Engineer to join the team. This individual will be responsible for developing and implementing wafer probe and final test solutions for bipolar transistor, MOSFET and diode semiconductors. They will design, develop, and troubleshoot test fixtures to execute MIL-STD-750 and MIL-STD-883 Test Methods. In addition, they will perform analysis of lot data to determine Delta parameters and Three Sigma calculations.

• Perform DC and AC bench measurements of semiconductors using various equipment like Lorlin or TESEC semiconductor testers, Spectrum analyzer, Oscilloscope and Pulse generator.
• Documentation of test methodology, operating instructions, qualification protocols, and development of test procedure documents to support standardized testing and training.
• Perform data analysis from lot measurements to evaluate trends, establish baseline performance, calculate delta parameters and three sigma limits, and identify abnormal variation affecting yield, quality, or reliability.
• Design and develop test hardware (e.g., interface boards, sockets, fixtures) and software for DC and AC measurements (e.g., switching time, hfe, leakage).
• Perform and debug test programs, tester hardware, and bench setups for accurate measurements.
• Selection and qualification of vendors for parts and materials to be used in test hardware.
• Work closely with Wafer Fab, Assembly, and Test teams to find solutions to production issues including identifying root causes and implementing corrective actions.
• Support failure analysis and investigation of failed parts and materials.
• Uphold the company’s core values of Integrity, Innovation, Accountability, and Teamwork.
• Demonstrate behavior consistent with the company’s Code of Ethics and Conduct.
• It is the responsibility of every employee to report to their manager or a member of senior management any quality problems or defects in order for corrective action to be implemented and to avoid recurrence of the problem.
• Duties may be modified or assigned at any time to meet the needs of the business.

• Bachelor’s degree in Electronics/Electrical engineering or related field required. Master’s degree is highly desired.
• 1+ years’ experience in testing semiconductors in a production setting in accordance with space, military, or government specifications required.
• Must have strong organizational, communication, and problem-solving skills with the ability to manage multiple priorities in a fast-paced manufacturing environment.
• Must have knowledge of physics of semiconductors, test principles and test parameters definition as they apply to small signal bipolar transistors, Schottky diodes, rectifiers, MOSFET’s, and optocouplers.
• Knowledge of ATE, TESEC ATE systems a plus.
• Knowledge of curve tracers, pulse and waveform generators, various power supplies and miscellaneous measurement equipment required. Knowledge of high frequency test techniques and equipment (up to 5 GHz) preferred.
• Must have proficiency in the set-up, calibration and performance of various dynamic and high frequency parameter testing as it applies to above-listed device types: switching times, safe operating area, noise measurements, etc.
• Familiarity with MIL-PRF-19500, MIL-PRF-38535, MIL-PRF-38534, AEC-Q documents, and…
