Hello everyone! I hope you all will be absolutely fine and having fun. Today, I am going to give you detailed discussion on Introduction to LM2904. LM 2904 consists of two builtin amplifiers. These amplifiers have high gain and they are internally frequency compensated. These amplifiers are designed for the operation from a single power supply for a large range of voltages. We can also operate them from multiply power supplies as well.
LM-2904 operates on 3.3V power supply, it is the most common power supply in digital systems. LM 2904 is also available in small sizes i.e. they are available in the latest technology DSBGA. LM-2904 has a lot unique features in comparison to the other standard amplifiers. These features include large DC voltage ga ...
I remember the first time I handed off a PCB project without thinking hard enough about the assembly process. The board came back looking fine. Then we started testing. Footprint mismatch on a critical power IC. Wrong polarity on an electrolytic cap. Two components missing entirely. Three weeks of schedule gone. The factory had done exactly what we asked them to do. The problem was what we asked for.That experience taught me something most engineering programs never cover. The assembly model you choose matters as much as the circuit design itself. And turnkey PCB assembly is one of those decisions that gets made too casually, too often.What Turnkey PCB Assembly Actually Means
The word turnkey gets used loosely in manufacturing. In PCB assembly it ha ...
Hello knowledge seekers! welcome to an overview of thin film transistors. I hope you are doing well. Thin film transistors are crucial components of digital display. These transistors have radically transformed our devices and the lifestyle of digital display electronic users. These are the mainstay of major aspects of our lives, from our daily life devices to the big industries, security, medical equipment, and many other departments. These transistors are the driving force behind the success of flat panel displays and most probably, the displays you are reading this article on, such as laptops, mobile screens, monitors, LCDs, etc., using thin film transistors.Today, the motto of this long article is the exploration of thin film transistors. We’ll embark on the foundational introduction o ...
To understand this section, we must know a little history. The history of the development of printed circuits is not as old as that of the industrial revolution, around 1950 is when the first PCBs began to be commercialized, however, in the early 1900s it was when the first attempts at PCB designs emerged.
The human being had the need to have electrical equipment that had a reduced size, before this the search began to replace the complex and extensive cable connections with electronic components.
It was on March 2, 1925, that Charles Ducas first filed a patent that included creating an electrical path directly on an insulating surface.
Technology has advanced and electronics are not left behind, as can be seen in the previous image, the first pr ...
Hello everyone, I hope you all are doing great. Today, we are going to share the 9th chapter in the PCB learning series, where we will have a look at the difference between Through-hole and Surface-mount technology.In our previous lectures, we studied both THT and SMT methods separately and have seen that both are used for components mounting on the PCB board. So, today, we will have a look at the difference between the two techniques. So, let's get started without wasting any time.
Through-Hole vs Surface-Mount
Let us know have a look at these differences and get to know the way forward when it comes to the process of component selection whether SMT or DIP.
Definition - THT vs SMT
THT stands for through-hole technology.
In Through-hole technology, components are mounted by ...
Hello everyone! I hope you all will be absolutely fine and having fun. Today, I am going to give you a detailed Introduction to BC547. It is an NPN bipolar junction transistor (BJT), mainly used for switching and current amplification.
Its maximum current gain is around 800. So, let's have a detailed overview of BC 547.
Introduction to BC547
BC547 is a 3-Terminal NPN Bipolar Junction Transistor(BJT), mostly used for switching purposes and current amplification.
BC547 Pins(Terminals) from left to right are called:
Collector.
Base.
Emitter.
Depending on the voltage applied at Base Terminal, BC547 can operate in two states, named:
Forward Biased.
Reverse Biased.
BC547 as Reverse Bias ...

Hi readers! I hope you are well and finding some thrilling advancement. In the high-speed electronic world where accuracy cannot be compromised and error is unthinkable, the Flying Probe Test is the unsung hero of PCB integrity. Today, the topic of our discourse is the Flying Probe Test and its use in PCB Fabrication.
In the complex realm of contemporary electronics, the dependability of a printed circuit board (PCB) can either make or destroy a product. With devices shrinking in size, speeding up in performance, and becoming increasingly feature-dense, the need for unflinching quality and accuracy in PCB manufacturing has grown stronger. Getting each trace, via, and connection perfectly manufactured is no longer a choice; it's a necessity. That's where Flying Probe Testing (FPT) comes in ...
Hello readers, I hope you are all doing great. Welcome to the 2nd lecture of Section 5(ESP32 Sensors) in the ESP32 Programming Series. In the previous tutorial, we discussed the built-in ESP32 Hall Effect Sensor. In this tutorial, we will discuss another inbuilt sensor of the ESP32 i.e. Capacitive Touch Sensor.
ESP32 Board has 10 built-in capacitive touch pins, which generate an electrical signal when someone touches these pins. These ESP32 touch pins are normally used to wake up the board from deep sleep mode. These touch pins are also used to replace the normal mechanical buttons with touch pads, improving the presentation of the IoT projects.
Here's the video demonstration of the ESP32 Capacitive Touch Sensor:
Before going forward, let's first understand how this touch sens ...
Contemporary engineering facilities are dependent on stable transference of loads involved between steel structures and concrete foundations. This connection is ensured by two important parts that include foundation bolts and embedded concrete plates. These elements play a crucial role in structural stability, proper alignment and durability in civil, mechanical and industrial engineering activities.
This paper describes the operation of FastenMetal Foundation Bolts and embedded concrete plates in the engineering systems and the reason why they cannot be ignored when it comes to the foundation and structural design.
What Are Foundation Bolts?
Foundation bolts, also called anchor bolts are fastening elements, which are used to hold structural e ...
