In the process of learning electronics, we often see Printed Circuit Boards (PCBs) and Integrated Circuits (ICs). Many people find it difficult to distinguish between these two concepts. In fact, they are not that complicated. Today, let’s clarify the differences between PCBs and integrated circuits. What is PCB? A PCB (Printed Circuit Board) is an … Read more
Rx is a resistor, there are many resistors in the circuit diagram, numbered sequentially, R1, R2… Cx is a non-polar capacitor, anti-interference capacitor at the power input terminal. IC is an integrated circuit module. Ux is an IC (integrated circuit component). Tx is a test point (for factory testing). Spk1 is a Speaker (buzzer, horn). … Read more
In our daily work and life, we often use various electronic or electrical products, such as computers, mobile phones, televisions, refrigerators, washing machines, etc.If we take these products apart, we will see a green board like the one below.Sometimes it can be blue or black.Everyone knows that this green board is called a circuit board. … Read more

On September 12, 1958, Jack Kilby from Texas Instruments successfully integrated five components, including germanium transistors, to create the world’s first germanium integrated circuit. The following July, Robert Norton Noyce from Fairchild Semiconductor invented the world’s first silicon integrated circuit based on silicon planar technology. Jack Kilby (left) and Robert Noyce (right) As we all … Read more
Source: Semiconductor Industry Observation (ID: icbank) Authors: By Pavan H Vora, Ronak Lad (Einfochips Pvt. Ltd.) In 1958, Texas Instruments (TI) manufactured the first integrated circuit trigger using two transistors. Today’s chips contain over tens of billions of transistors. Memory that once supported an entire company’s accounting system has now transformed into a smartphone that … Read more
First, let’s explain what tape-out is; it is not the same as mass production. Tape-out, in English, is called Tape Out, is the process of converting a designed integrated circuit (IC) layout into an actual physical chip. It is like an assembly line, manufacturing chips through a series of process steps. Chip design companies hand … Read more
