Reliability Testing

Engent utilizes state-of-the-art electronic product testing equipment to ensure maximum product reliability and performance. Our equipment tests for shock, vibration, temperature, and acceleration, and is capable of qualification and cycling testing.

Our industry best equipment includes, but is not limited to:

  • Liquid thermal shock chamber
  • Air thermal shock chamber
  • Highly accelerated stress test (HAST) chamber
  • Accelerated stress test system (HALT)
  • Industrial oven
  • AGREE Chamber
  • Electrodynamic vibration system

Our electronic product testing services provide validation that every product we deliver will perform successfully under realistic, expected conditions.

Engent’s reliability testing includes:

  • New package and assembly qualification (Level I and II)
  • Product-level testing

Engent maintain full compliance with the rules and regulations set forth by the United States Consumer Product Safety Commission. Our teams possess extensive experience in electronic product testing, and are dedicated to contributing to advancements that mature industry technologies.

Packaging and Process Technology Selection and Qualification

  • Semiconductor wafer solder bumping technologies specification (evaporation, electroplating, stencil printing)
  • Under bump metalization specification (sputtering, evaporation, electroless plating)

Advanced Assembly Technology Success Story

When an OEM needed very quick-turn assembly of a new board using consigned material, they found that their EMS provider’s high-volume lines were running with no open capacity.

Advanced Assembly Technology Solution:

Engent set up, assembled and delivered the boards – ahead of schedule. Of more significance is the early determination during first article inspection of a thin HASL finish on the boards, which would have resulted in poor solderability. New boards were obtained and the total solution of process knowledge, capability, and customer support allowed this product to be delivered on time.
