INTRODUCTION:- Instrumentation Ltd is a Public Sector unit . it is Undertaking Ministry of Heavy Industries.
It is set up in kota April,1964.
it is based on C-DOT (Centre for Development of Telematics) Tech.
It has a Plant HQ at Kota with another plant at Palakkad, Kerala.
International office in Malaysia, Iran.

PCB CENTRE:-
Gurukul Institute of Engineering & Technology, Kota
» Instrumentation Limited 's Electronic assemblies plant at Kota assemble & test the PCBs. » It is spread over 20,000 square feet.
» PTH and SMT Techniques are used for assembling.
» The unit has fully automatic programmable Pick & Place machine.
EQUIPMENTS ARE USED FOR ASSEMBLING AND MANUFACTURING OF PCB:-
Gurukul Institute of Engineering & Technology, Kota
1.) BACKING MACHINE
2.) CUTTER AND BENDER MACHINE
3.) WAVE SOLDRING MACHINE 4.) PICK AND PLACE MACHINE
WHAT IS PCB? Type 1 – Single Sided PCB
Type 2 – Double sided PCB
Type 3 – Multilayered PCB
PCB, is used to mechanically support and electrically connect electronic components using conductive tracks.
» It is like a microwave oven.
» Used for testing the PCB for any type of defects(bending,breaking ,removal of copper tracks ) by heating.
»Heating of the PCB done at 200-300 C.
BACKING MACHINE:-

THERE ARE TWO TECHNIQUES FOR MANUFACTURING THE PCB »»
(1)Platted Through Hole Technique(PTH)
(2) Surface Mount Technique(SMT)
TWO TECHNIQUES
Gurukul Institute of Engineering & Technology, Kota
PLATTED THROUGH HOLE TECHNIQUE ( PTH):
» In PTH technique components are Mounted on PCB by DRILLED hole.
» For mounting the components wave-soldering machine is used for soldering through hole components .

FLUXING ZONE
PRE-HEATING ZONE
SOLDERING ZONE
In Surface mount technology (SMT) the components are mounted directly onto the surface of Printed circuit board(PCB).
High-speed designs may require SMT technology.
In this technique large no. of small components are mounted.
SURFACE-MOUNT TECHNOLOGY(SMT):

CONCLUSIONTraining from INSTRUMENTATION LIMITED, kota ,is a tremendous experience for me.
During my training session I get lot of knowledge from I.L.
I get knowledge about manufacturing of PCB,UPS,RSR,SBC etc. I also did practical that was the great experience for me. Gurukul Institute of Engineering & Technology, Kota
