3. 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 ILJIN Pvt . Ltd

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. ILJIN Pvt.Ltd

7. 2. High volatge tester High voltage transformers  are normally used in  high voltage  labs for  testing purpose . 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. ILJIN Pvt.Ltd

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. ILJIN Pvt.Ltd

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 square metre . 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 ILJIN Pvt.Ltd

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. ILJIN Pvt.Ltd

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. ILJIN Pvt.Ltd

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 ILJIN Pvt.Ltd

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. ILJIN Pvt.Ltd

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. ILJIN Pvt.Ltd

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. ILJIN Pvt.Ltd

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 . ILJIN Pvt.Ltd

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 : All display is ON. Display glow one by one . Display is glow and then hold for few seconds. ILJIN Pvt.Ltd

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 . ILJIN Pvt.Ltd

21. XRF - MACHINE 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.
