Hello friends, I hope all of you are fine. In today’s tutorial, we are gonna have a look at PCB Invention and History. The PCB stands for printed circuit board, PCB is a thin chip created by compound epoxy, glass-fiber, or laminated different substances. There are many current-carrying ways are designed on the chip, which is used different components like resistor, capacitors, a transistor with each other and current flows to these components through printed ways paths.
PCB is used in different electronic instruments, projects or devices like mobiles, laptops, computers, etc. Nowadays almost every circuit of any device is created on the PCB. In computers, all components used in computer’s motherboard are assembled on printed circuit board. Before PCB to connect different components wire wrap and one point to other point assembling were famous but these days they are no using. PCB (printed circuit board) needs further enterprise struggle to design the circuitry, but production and its construction are automatic. Special CAD (computer-aided design) software is offered printed on the board. Production of circuitries with PCB (printed circuit board) is inexpensive and quicker than with other cabling techniques, as apparatuses are riding and connect in one process. Huge quantity of PCB (printed circuit board) can be produced at the same time. PCB (printed circuit board) can also be created by hand in less amounts, with abridged assistance.
Here i further want to mentined that if you are working at electronic board and need PCB you must have to contact PCB supplier. I want to resolve your query about that and there is best PCB supplier that is JLCPCB who ffering PCB boards in very high quality and reasonable prices.
JLCPCB is the China based PCB supplier that is offering different services related to PCB and their products all over the world. It was established in 2006 and has five working factories in China. There are almost ten lac customers they have with that almost twenty thousand orders they are dealing with all over the world. It is the largest PCB prototyping service provider in Asia and they have the capacity of six twenty thousand productions of one layer double layer and multiple layer PCB boards. JLCPCB regularly driven to become more efficient and reduce costs
In today’s post, we will have a look at its construction, uses, types, and other related terms. So let’s get started with what is PCB (Printed Circuit Board).
What is PCB (Printed Circuit Board)?
- PCB board is the basic component of electronic products and services that is used for providing physical support and different wires connected on the board for making circuits and project layouts. The composition of the PCB board is fiberglass, composite epoxy, and some other composite material.
- PCB board is a device that is compatible and connects components in all types of industrial projects.
- Project components are configured with the use of tracks and pads for conductive materials like etched copper, and they are configured with the non-conductive substrate that is in the form of epoxy and fiberglass.
- Different components connected on boards are resistors, capacitors, etc., and make a strong connection with soldering on the board.
- Some advanced PCB designs also come with components that are configured on substrate sheets.
- • A commonly used substrate sheet is FR4, glass-reinforced epoxy laminate sheeting.
History of PCB
- Before the use of PCB board circuits were created by making connections of wire for project requirements.
- The framework was configured with metallic frame and different components joined on that structure through insulating materials and a connection point was made with metal.
- Older circuits were larger size and has high weight and difficult to handle and mange also their creation cost was higher.
How PCB Was Invented
- When the PCB was not invented, there was the common use of point-to-point assembly processes. This process was not very effective and reliable.
- With the passage of time and the requirement of more advanced and reliable circuit construction technical staff, though, to make PCB boards.
- So in the 1920s, engineers and technicians used the wood for board creation and holed made on the board through the use of the drill. Over the surface of the board, flat brass wires are used for circuit creation.
- These boards were used in radios and gramophones.
- • The first PCB board was practically invented in 1936 by Austrian designer Paul Eisler.
- This first PCB was used in the radio network for circuit creation, and then it was used by the USA military. After that, it has become very common and is now used in everything from small-sized calculator boards to larger circuit electronic devices.
PCB Applications
- PCB board is part of different electronic devices like radios and mobile phones.
- The computer circuits, like motherboards, come with PCBs, such as tablets, laptops, etc.
- It is also used for DVD circuits, TVs, LEDs, etc.
- The devices used at homes, like microwaves, ovens, and clocks, are made on PCB boards.
- Industrial machine circuits are also made on these boards, so they are considered as building blocks.
- Flow meters and temperature meters also use PCBs.
- • X-ray machines, CT scans, and other medical devices made on PCBs
