Introduction to Surface Mount TechnologyABDUL MUNAFF
Surface Mount Technology (SMT) refers to a specific type of electronics assembly where electronic components are attached to the surface of a substrate (typically a printed circuit board).
SMT is a modern alternative to traditional thru-hole technology where components are attached to substrates by leads that passed through holes in the PCB.
Surface Mount components require less space so SMT is helpful in product miniaturization.

This presentation is all about the working of Surface mount technology department of electronics industry. This is my personal experience at iljin electronics pvt. ltd. during my internship.
A printed circuit board (PCB) mechanically supports and electrically connects electronic components using conductive tracks, pads and other features etched from copper sheets laminated onto a non-conductive substrate.
Sorry to say but the college spelling is wrong actually "technology" word is missing. Its by mistake.
A presentation on printed circuit board designing. A brief discussion on pcb fabrication. Basic steps involved in it.

Courier management system project report.pdfKamal Acharya
It is now-a-days very important for the people to send or receive articles like imported furniture, electronic items, gifts, business goods and the like. People depend vastly on different transport systems which mostly use the manual way of receiving and delivering the articles. There is no way to track the articles till they are received and there is no way to let the customer know what happened in transit, once he booked some articles. In such a situation, we need a system which completely computerizes the cargo activities including time to time tracking of the articles sent. This need is fulfilled by Courier Management System software which is online software for the cargo management people that enables them to receive the goods from a source and send them to a required destination and track their status from time to time.

EIA-96 marking method:
a new coding system has appeared on 1% types.
It consists of a three-character code.
A look up table is provided.
The first two digits signify the 3 significant digits of the resistor value,
using the lookup table below.
The third character - a letter - signifies the multiplier for 1% Resistors

Calculating SMD Capacitor Value – EIA 96 Marking Method
EIA-96 marking method:
SMD ceramic capacitors are sometimes marked with a code, consisting of
one or two letters and a digit.
The first letter if present is a manufacturer code (i.e K for Kemet, etc.)
The second letter the mantissa and the digit the exponent (multiplier) of
the capacitance in Pico farad (PF)

Less Than 1000pf = Pf (Pico farad)
More Than 1000pf =Nf (Nan farad)
More Than 1000000pf =Uf (Microfarad)
