ELECTRONICS MECHANIC - CITS

EXERCISE 134: Demonstrate different types of ICs

Objectives

At the end of this exercise you shall be able to
• to demonstrate Introduction of Integrated Circuit (ICs)
• to demonstrate different type of ICs.

Motivations
• an IC can function as an amplifier, oscillator, timer,counter, logic gate, computer memory, etc.

Requirements

Tools/Materials
• IC Chip Remover - 4 Pieces. • CRO - 1 No.
• Pin set - 1 No. • Bread board - 1 No.
• Tool kit - 1 Set. • Connecting wires and probes - 1 No.
• Resister - 1 No.

Procedure

Integrated Circuits

Integrated circuits is nothing but the entire circuit of an electronic circuit is designed and fabricated in semiconductor
material with VLSI(very large Scale Integration) technology as a single module. It is compact in size and consuming
less power. Especially there are three main type IC s in mobile phone.
a PinIC
b PathIC
c MBGA(MicroBallGridArray)/BalltypeIC

Pin IC
The chip is packaged in a plastic holder with pins which will fit the holes on strip board and breadboards.

You can mount and unmount or replace these IC s using SMD rework station. However when you replace like
this IC you must mount all pin to the PCB and do not short circuit. Specially Latest mobile phones have not like
this IC s. But when you training to mount and unmount these Ic s then you will be able to replace chinease phone
display , Switches ... etc.
