INTRODUCTION
“INSTRUMENTATION LTD, KOTA” is a govt. of India enterprises established in Kota
(Raj.) in 1966-67 with the prime objective of attaining self-reliance in the field of
contract & automation for the process industry.
The major products that IL presently manufacturing are: -
1) Process control Instruments
2) Control Valves
3) Railway Signaling System
4) Sets of Telecommunication
5) Microprocessor Based Recorders
6) Digital switching system
7) Rural Automatic Exchange
8) Main Automatic Exchange
9) Panels
10)Defense Products
Today, IL is supplying these control Equipments to various sectors of the industries viz.
power, steel fertilizer, chemical, petrochemical, refineries, cement, paper textiles,
space, oil, gas, the turn over target is more than 150 cores.
Advantage of SMT
SMT allows production of more reliable assemblies, increased board density, and
reduced weight, volume and cost. Considerable cost saving can also be realized
through a reduction in material as well as the labor costs associated with automated
assembly.
Pick and mount machine:-
This machine is very important it is only one machine at IL , Kota in Rajasthan. This
machine is very costly (6 crores Rs. /-) It picks up small component. With the help of
programming we put in the computer and mount on the PCB. This machine mount
small Component on the PCB at first after this we solder the PCB. After this we solder
the PCB component after this we take out card and test it. When any component short
then we check it manually and remove difficulties and after we give to testing after
testing we clean the card and lequer.
.Issue of Kits:
During the assembly of PCB’s several operations are required initially various
components which are required for the purpose of assembly are received from the
store, in the form of kit then following process are made on the PCB’s before final
clearance and dispatch to the testing and repairing center.
Numbering:-
The purpose of numbering the PCB’s is to lay down the procedure for identification &
traceability of the products. The PCB’s are identified at the initial stages and higher
stages by providing the serial no. on them which is of 10 digit code.
. Baking: -
Before proceeding to the various operations, the baking operation is done due to
following : -
During soldering the card passes through temperature range in
pre-heating and soldering chamber. If baking is not done prior to soldering the card
may be distorted at high temperature. During baking the card becomes dry & it can
bear thermal shocks during soldering.
The baking is done in a furnace at 1200c. The baking erent cards.
· It is 1 hour in use of simple layer.
· 4 Hour in case of 2-4 layers.
· 8 Hour for above 4 layers.
4 .Mechanical Assembly:-
Although we are using the electronic components in assembly. But some
components are assembled fastened by mechanical tools fasters. Components which
are mechanically assembled are connectors, injectors, switches etc
