GLOSSARY OF TECHNICAL TERMS
This glossary contains explanation of certain terms used throughout this Prospectus in connection with our Group and business. The terminologies and their meanings may not correspond to the standard industry meanings usage of these terms.
Ampere : A unit of measurement for electric current
Automated Testing Equipment or ATE : An apparatus which performs tests on electronics and semiconductor products
Bushing : A fixed or removable cylindrical lining added to an opening to constrain, guide, or reduce abrasion
CNC : A machine incorporated with computer numerical controls, automatic tool
changers, tool magazines and coolant systems, used in a milling/tapping
process to remove unwanted materials from the workpiece or to make
holes in the workpiece
Computer-Aided Design or CAD : A computer technology/software for design and design documentation. CAD software replaces manual drafting with an automated process
Contact/Probe pins : A tiny object used to establish a connection between two (2) PCBs
Conversion kits : A collection of precision fixtures which allows a test handler to
accommodate different device sizes and types
Coordinate­ : A machine used in to accurately measure the physical geometrical
Measuring or CMM Machine characteristics of an object
Deburring : A process to remove unwanted excess material and smoothen rough edges or ridges of an object (usually a metal)
Decibel or dB : A unit of measurement for the ratio of intensity or power
Device Under Test or : Any electronic device or assembly under test to determine the
DUT performance and proficiency
Dowel pins : Objects engineered to tight tolerance limits, which are inserted into holes (either wider or narrower than the pin) for use as precise locating or
alignment devices
Engineering plastics : A group of plastic materials that are used in applications generally requiring higher performance in terms of heat resistance, chemical
resistance, impact fire retardancy or mechanical strength, compared to
the more widely used commodity plastics (such as polystyrene, polyvinyl
chloride (“PVC”), polypropylene and polyethylene)
Ferrous : A material which contains iron that are primarily used for their tensile
strength and durability. Examples of ferrous materials include mild steel,
carbon steel, stainless steel, cast iron and wrought iron
Gigahertz or GHz : A unit of measurement for alternating current or electromagnetic wave frequencies equal to one (1) billion hertz
Grinding machine : A machine that performs very light cutting using abrasive wheel to remove material from the workpiece

GLOSSARY OF TECHNICAL TERMS (cont’d)
Hand lids : A device used during the setup of manual test to secure a DUT in place
Heat sink : A device which keepsdissipation of heat a hot component cool by assisting in the
Integrated Circuit IC or : A set of semiconductor devices on a thin semiconductor material, which is usually silicon plate (i.e. chip) of
Leads/balls of an IC : Parts of an IC package which conducts electrical signals between the IC and the PCB on which the IC is placed. These parts may take the form of pins or tiny balls of solder
MasterCam : A computer-aided manufacturing software program to produce mechanical drawings of parts, create three (3)-dimensional wire frame models and guide CNC machines tools in the manufacture of parts
Metrology : A science of measurement which includes all theoretical and practical measurement to validate data obtained from measuring equipment in terms of accuracy and precision
Micro milling machine : A machine incorporated with CNC controls, used in a milling/tapping process to remove materials from smaller workpiece or to make holes in smaller workpiece
Micron : A unit of measurement for one millionth of a metre
Milling : A machining process of cutting to remove material from the surface of the workpiece
Modular components : Components composed of separate components that can be connected together or separated
Outsourced Semiconductor Assembly and Test Companies or OSAT : Companies that specialise in assembly, testing and packaging services for semiconductor
Precision engineering parts : Parts which are engineered to have exceptionally tight tolerance, reusable and remain stable while being used
Printed Circuit Board or PCB : An object which mechanically supports and electrically connects electronic components using conductive trace, pads and other features etched from copper sheets laminated onto a non-conductive substrate
Radio RF Frequency or : A frequency in which radio waves may be transmitted
RF connector : A RF connector is an electrical connector which is typically used with coaxial cables, and is designed to perform in high frequency, high power, low loss or extreme temperature situations. These connectors are usually used in wireless telecommunications applications
SolidWorks : A CAD software program for three (3)-dimensional product design and engineering
Stiffeners : A device used to dock a PCB in place to ensure that it is in alignment with the test handler and/or tester during the testing of IC packages/wafers

Tapping : A process of cutting or forming a surface inside a hole which acts as a
nut, so that bolts can be screwed into the holes
Test sockets : A device which is placed on a PCB and are configured to receive and protect the leads/balls of an IC
Tool presetter : A device that accurately measures the tools to assure that they are precisely set in the tool holders in the machine
Wafers : A thin slice of semiconductor material, such as crystalline silicon, used in the fabrication of IC
