The history of circuit boards dates back to mid-1930s, when an Austrian engineer Paul Eisler invented the PCB while designing a radio set. As explained above, a printed circuit board is a board made of one or more layers of insulating material (fiberglass, ceramic, highly heat-resistant plastic or any other dielectric material) with conductive pathways etched with metal such as copper. For a perfect and reliable circuit board design, good knowledge and understanding of PCB layout techniques and basic understanding of circuit operation is needed. A circuit diagram is a diagram showing and explaining how and where electronic components will be mounted to achieve the target product.
Learn and understand all the common symbols and abbreviations for electronic components to be used on the diagram. Mounting electronic components on the circuit board and getting it ready for use is what is called circuit board assembly.

Reported comments and users are reviewed by Autoblog staff 24 hours a day, seven days a week to determine whether they violate Community Guideline. IPC 2221A generic standard on printed board design provides rules for manufacturing circuit boards and quality guidelines.
It has to be noted that IPC and other standards will provide information on how to properly route the board. While designing a printed circuit board prototype, one must take proper care of the substrate material based of type of soldering technology and components to be used.

So that signals flow from left to right (inputs and controls should be on the left, outputs on the right).
A Circuit board assembly process may use through-hole assembly technology or surface mount technology (SMT) or a mix to both.
This website provides basic electronics tutorial for beginners, students, teachers, electrical and electronics professionals.
Accounts are penalized for Community Guidelines violations and serious or repeated violations can lead to account termination. A substrate or board may have only one single layer (single-layer circuit board) or more than one layer (multilayer circuit board). After this, the use and application of circuit boards because commercial in electronics industry. Once all electronic components are soldered on the circuit board and the board is ready for use, it is called printed circuit assembly (PCA) or printed circuit board assembly (PCBA). These information and guidelines is applicable for all types of circuit boards including single-layer and multilayer PCBs and information includes substrate information, material properties, criteria for surface plating, conductor thickness, component placement, dimensioning and tolerance rules and more.
The width of the traces of the circuit board (circuit conductors) should be chosen wisely based on expected maximum temperature rise at the rated current and acceptable impedance.
Once the circuit board is assembled with components it is ready for testing and finally to be assembled with the product. In this basic electronics tutorial website you will find tutorials on electronic circuits, analog and digital electronics, electricity, static electricity, solar energy, electronic components and parts, soldering and desoldering and more.

A conductive metal such as copper is used to make conductive pathway or traces to facilitate flow of electricity. Other points to keep in mind with circuit board design are CTE, cost and dielectric properties.
But it is not guaranteed that a circuit board assembly will give 100% zero defect production.
The basic electronics tutorials are also offered in PDF, video and PowerPoint ppt for free download. Once these conductive traces are etched on the substrate, it is termed as “printed circuit board”. The designer needs to carefully balance the constraints of cost with reliability and performance needs. The purpose of this site is to give students and beginners studying Electronics, good Basic Electronics Tutorials and information to help gain knowledge and proper understanding of the subject of Electronics. Again the technology used to solder these components on the circuit board can be through-hole technology or surface mount technology.
Soldering material may include solder in the form of solder wire, solder paste, solder balls for BGA (ball grid array) and solder flux.
