Overview

Quasi-S Engineering Service division consists of teams of specialists with vast experiences in the following major roles:

  • Equipment installation, calibration, buy-off, evaluation, trouble shooting and preventive maintenance service.
  • Site measurement includes EMF, noise and vibration elimination.
  • Vacuum Pump preventive and corrective maintenance, UPS installation and battery replacement service and many more.
  • Provide customized solution and tailor to the need in overcoming customers’ problems. Unlike any common engineering services available in the market, we specifically focus only on projects that sync with our expertise.
  • 3D CAD design and drafting services (using latest Autodesk Inventor) to clients
    – For complicated and sophisticated mechanical structures that require in-depth visualisation.
    – For “Reverse Engineering”, mainly for parts that are EOL and no longer available.

Engineering Service Examples

Below are examples of Engineering projects and several drafting assignments we have undertaken. Although the list is exhaustive, due to customer proprietary requirements, the examples shown for our service is limited.

In-situ Heater Stage For Scanned Electron Microscope (SEM)

Quasi-S in-situ heater stage is a high temperature heating module for material handling experiments in combination with microscopic observation. Notably, this SEM sample holder with in-situ heater capabilities for SE imaging. It is designed to allow universal handling of various specimens. The heater can be mounted on the stage of a SEM like a regular sample. A K-type thermocouple allows the measurement of the temperature at the specimens. Consequently, the temperature can be observed and controlled by PID temperature controller.

This in-situ heater stage provides sample heating up to 300⁰C and the system consists of:

  • Heater stage with K type thermocouple, cartridge heater and dovetail base holder
  • Flange with feed through
  • Temperature controller module

Site Measurement Service (Electromagnetic, Vibration & Acoustics)

Quasi-S offers site measurement service using high precision Analysis System. The standard measurement provides data about a proposed site for equipment installation such as a Scanning Electron Microscope and other equipment sensitive to environmental conditions. Specifically, we measure magnetic fields and floor vibrations in X, Y, and Z directions and acoustic levels in units appropriate for direct comparison with the environmental specifications of the equipment to be installed.

Given that the latest equipment on the market requires low levels of magnetic field and magnetic field gradients, we uniquely offer surveys measuring the field simultaneously to obtain this gradient information for both DC and AC fields. We also provide technical solutions and customized designs to cancel or minimize environmental interference affecting your work area and equipment.

Noise Reduction Enclosure Service

Another project successfully undertaken by Quasi-S. This simple, cost effective enclosure not only helps our client to reduce health hazard due to noise generated by over 40 pumps, but the external casing creates neatness in the factory 5S initiative.

Furthermore, with the enclosure Temperature peaked at 49°C and remained constant after 8hrs of continuous operation.
