3. INC0MING QUALITY CONTROL
• Incoming quality control (IQC) is the process of controlling the quality of
materials and parts for manufacturing a product before production begins.
With incoming inspection, you can control for quality even before conducting
a first article inspection or a during production inspection.
• Every component is verify with it’s JIR(joint inspection report) in terms of
dimensions and visually with help of sampling process.
• The Sampling plan 105D is used in IQC in which S1/2.5 is used for checking
dimension and S2/.65 is used for checking visually of any component or any
wires

6. 1. LCR
METER• An LCR meter is a type of electronic test equipment used to measure
the inductance (L), capacitance (C), and resistance (R) of an electronic
component[1]. In the simpler versions of this instrument the impedance was
measured internally and converted for display to the corresponding capacitance
or inductance value. Readings should be reasonably accurate if the capacitor or
inductor device under test does not have a significant resistive component of
impedance.

7. 2. HIGH VOLATGE TESTER
• High voltage transformers are normally used in high voltage labs
for testingpurpose. This transformer is subjected to transient voltages and
surges during their normal operation when the insulation under test breaks down.
• High Voltage testing is usually performed to qualify the device to operate safely
during rated electrical conditions, a way to check the effectiveness of its insulation.
The objective sought during the high voltage testing will determine the type and
amount of voltage applied and the acceptable current flow.

8. 3. DIGITAL MICRO OHM METER
• An ohmmeter is an electrical instrument that measures electrical
resistance, the opposition to an electric current. Micro-ohmmeters (micro
ohmmeter or micro ohmmeter) make low resistance measurements.
Megohmmeters (also a trademarked device Megger) measure large values
of resistance.

9. 4. LUX METER
• Lux. The lux (symbol: lx) is the SI derived unit of illuminance and
luminous emittance, measuring luminous flux per unit area. It is equal
to one lumen per squaremetre. In photometry, this is used as a
measure of the intensity, as perceived by the human eye, of light that
hits or passes through a surface.
• Entrance areas and lobbies require this level of light, and it is also
the minimum for a restaurant dining area. 500 lux – Retail spaces
should have this as a minimum light level, as should
general office spaces. This level should be suitable for prolonged
work on computers, machinery and reading

10. 5. PUPPY DIAL
• In various contexts of science, technology, and manufacturing (such
as machining, fabricating, and additive manufacturing), an indicator is
any of various instruments used to accurately measure small
distances and angles, and amplify them to make them more obvious.

11. 6. DIGITAL HEIGHT GAUGE
• A height gauge is a measuring device used for determining
the height of objects, and for marking of items to be worked on.
• Height gauges may also be used to measure the height of an object
by using the underside of the scriber as the datum. The datum may be
permanently fixed or the height gauge may have provision to adjust
the scale, this is done by sliding the scale vertically along the body of
the height gauge by turning a fine feed screw at the top of the gauge;
then with the scriber set to the same level as the base, the scale can
be matched to it. This adjustment allows different scribers or probes to
be used, as well as adjusting for any errors in a damaged or
resharpened probe.

12. 7. PUSH PULL GAUGE
• A force gauge (also force gage) is a small measuring instrument
used across all industries to measure the force during
a push or pull test. Applications exist in research and development,
laboratory, quality, production and field environment.
• Applications
• Spring testing
• Metal wire testing
• Bursting strength testing of cardboards
• Weld force between electrodes
• Gun trigger testing

13. 8. MEASURING PIN GAUGE
• Pin Gauges & Measuring Pin Sets Micro Gauges / Kris. Measuring
pins are used for checking hole diameter, measuring distance between
holes , measuring dovetail, Measuring Over Pin Diameter of
Gears, Measuring width of grove etc
• The PIN GAUGE is the pin shape according to fixed size precisely. The
primary purpose of PIN GAUGE is to measure and inspect the diameter of
samll holes, it also can be used as a test bar for geometric deviations
measurements.

14. 9. DIGITAL VERNIER CALIPER
• The Digital Caliper (sometimes incorrectly called the Digital Vernier
Caliper) is a precision instrument that can be used to measure internal
and external distances extremely accurately.
• Digital calipers are easier to use as the measurement is clearly
displayed and also, by pressing the inch/mm button the distance can
be read as metric or imperial.

15. 10. DIGITAL MICRO
METER
• A micrometer sometimes known as a micrometer screw gauge, is a
device incorporating a calibrated screw widely used for accurate
measurement of components in mechanical engineering and
machining as well as most mechanical trades, along with other
metrological instruments such as dial, Vernier , and digital calipers.
ILJIN PVT.LTD

16. 11. DIGITAL IR TESTER
• Insulation resistance measurement is done using an IR
tester. This is a portable tool that is more or less an
ohmmeter with a built in generator that's used to produce
a high DC voltage. The voltage usually measures at least
500V, and causes a current to flow around the surface of
the insulation.
ILJIN PVT.LTD

17. 12. DIGITAL
MULTIMETER
• A digital multimeter is a test tool used to measure two or more
electrical values—principally voltage (volts), current (amps) and
resistance (ohms). It is a standard diagnostic tool for technicians in
the electrical/electronic industries.

18. 13.GAP
TESTER
• Gap tester is instrument used to identify or check any gap in PCB.
Placing on surface plate and then put gap tester instrument below the
PCB until PCB not lift .

19. 14. DISPLAY FLIM TESTING
JIG
Display Flim Testing JIG is a instrument to check the 7-segment display
by attaching their pins in JIG .
There are 3 modes :
1. All display is ON.
2. Display glow one by one .
3. Display is glow and then hold for few seconds.

20. 15. DIGITAL HUMIDITY AND TEMPERATURE
METER
• A humidity sensor (or hygrometer) senses, measures and reports both
moisture and air temperature. ... Relative humidity becomes an important
factor, when looking for comfort. A sample humidity
sensor. Humidity sensors work by detecting changes that alter electrical
currents or temperature in the air.
• A temperature meter is a device, typically, a thermocouple or RTD, that
provides for temperature measurement through an electrical signal. A
thermocouple (T/C) is made from two dissimilar metals that generate
electrical voltage in direct proportion to changes in temperature.

21. • X-ray fluorescence (XRF) is the emission of characteristic
"secondary" (or fluorescent) X-rays from a material that has been
excited by bombarding with high-energy X-rays or gamma rays.
• XRF (X-ray fluorescence) is a non-destructive analytical technique
used to determine the elemental composition of materials. XRF
analyzers determine the chemistry of a sample by measuring the
fluorescent (or secondary) X-ray emitted from a sample when it is
excited by a primary X-ray source.
