4 سال پیش،هیچوقت فکرنمیکردم اینقدر ذایقه ام عوض بشه که زیتون سبز دم دستم باشه و دونه دونه بردارم بخورم.به واقع زیتون جزو چیزایی بود که اصلا دوست نداشتم.مثل همه ی چیزایی که تا 3 سال پیش دوست نداشتم و الان میخورم.
واین مدل تغییرات تنها نمونه ی کوچکی از تغییراتی هستن که در طول زمان برای آدمها ایجاد میشه،بدون اینکه ادم حواسش باشه و اصلا متوجه بشه که چه اتفاقی داره واسش میوفته.

Overview
One of the key concepts in electronics is the printed circuit board or PCB. It's so fundamental that people often forget to explain what a PCB is. This tutorial will breakdown what makes up a PCB and some of the common terms used in the PCB world.
Over the next few pages, we'll discuss the composition of a printed circuit board, cover some terminology, a look at methods of assembly, and discuss briefly the design process behind creating a new PCB.
What's a PCB?
Printed circuit board is the most common name but may also be called "printed wiring boards" or "printed wiring cards". Before the advent of the PCB circuits were constructed through a laborious process of point-to-point wiring. This led to frequent failures at wire junctions and short circuits when wire insulation began
