6.  Quality is fitness for use.
 Quality involves meeting customer
need,preferences and exceeding it.
 DEFINATION:-
 Incoming quality control (IQC) is the process of
controlling the quality of materials and parts for
manufacturing a product before production begins.
... Whether you manufacture industrial or consumer
products, component and material quality is a key
determinant of finished product quality

7.  FUNCTION
 To satisfy Quality requirement.
 Verify and maintain desired level of quality in
existing product.
 ROLE
 To determine if the lot is “acceptable”(compliant)
or” not” before keeping it in stock or store room
 To check the desired specification of component
using various tools.
 If product is reject then keep this to hold and
inform vendor for returning process.
 If product is acceptable then store it in fifo order

INSTRUNMENT REQUIRED

11.  Used to measure intensity of light
 Lux stands for S.I unit of light illuminious
 Entrance areas and lobbies require this level of
light and it is also the minimum for a restaurant
dinning area 500 lux-retails spaces should have
this as a minimum light level
as should generel office spaces

12.  measure deck ,clearance,crankshaft thrust.
 used to accurately measure small distances
and angles, and amplify them to make them
more obvious.

14.  mainly used for testing the strength of
component like wire ,cable….etc
 The cablecomponent are stretched for a
certain desired value.

15.  *used for measuring length for small component
 In iqc small component are measured with accuracy
using this tool.
 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.

16.  Economical way to monitor
indoor temperature and humidity,
 At the same time it also have an alarm clock.
 Measures temperatures:-50°C~70°C(-58° F~158° F)
 .Humidity range: 20%~99%RH.

17.  Used for HV cable testing also need to supply
sufficient electric current. ... To limit this current, a
high resistance is connected in series with
transformer.
 Voltage withstand testing is done with a high
voltage source and voltage and current meters. A
single instrument called a "hipot tester" is often
used to perform this test.
 It applies the necessary
voltages to a device and
monitors leakage current.
The current can trip a
fault indicator

18.  known as a micrometer screw gauge, is a device
incorporating a calibrated screw widely used
for accurate measurement of
components[1] in mechanical
engineering and machining as well as most
mechanical trades,

19.  The Digital Micro-
ohmmeter finds application wherever low
resistance values are to be measured.
 It is an asset for electrical and electronic industry
 . It can be used for finding the resistance of
transformer or motor winding. It can be used to
calibrate ammeter shunt wires.

20.  PIN GAUGE. 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 small holes, it also can
be used as a test bar for geometric deviations
measurements.
 * PIN GAUGE with shank is less affected by
temperature

21.  A multi meter or a multi tester, also
known as a VOM(volt-ohm-millimeter)
is an electronic measuring instrument
that combines several measurement
functions in one unit

22.  A feeler gauge is a tool used to measure gap
widths. Feeler gauges are mostly used in
engineering to measure the clearance
between two parts

23.  First of all product invoice will be verified
 product will be stored at particular place
 product sample is verified using the chart
sample size code letter
 Using this chart product is decided
whether ok or NG
 if product is NG then prepare a report and
report to respective vendor
 if product is OK then it is send to the store
room and stored in proper manner and
also in FIFO order
 FIFO refers to first old product is used
after finishing old only new one is used

24.  *in store product are stored under satisfied
condition like humidity and temperature are
maintained.
 *condition for IC room
 Temperature:- MAXIMUM-28’C
 MINIMUM-22’C
 Humidity:- MAXIMUM-60%RH
 MINIMUM-40%RH
 *temperature and humidity are maintained using
AC and humidity stability chamber.
 *Halogen light are used with proper way(light
should not fall directly on Ic) for controlling
temperature and humidity.
 *According to demand component are taken out
from store in FIFO manner.

26.  *Quality is never ending prospect…..
 *increase in quality increase in product
 *Decrease cost and increase profit.
 *Thus quality control an inspection
from an integral part of company’s
management.
