A pcb button is a pushbutton or switch mounted on a circuit board that receives input signals from the user and converts them into electronic signals to control the operation of a device. Circuit board pushbuttons generally consist of a carbon membrane, a keypad, a flexible contact plate, a substrate, and contacts. The carbon film

Plated half holes are similar to plated through-holes, but occupy only half of the vertical space. This design makes them structurally more compact while maintaining good electrical and mechanical connectivity. Through soldering, these half-holes can connect individual PCB modules to the motherboard, providing superior joint access and coaxial alignment over conventional pads. Plated half hole

In the daily maintenance and troubleshooting of electronic equipment and electrical systems, the reliability of the switch, as a key component of the circuit control, directly affects the safety and stability of the entire system. The multimeter, as an essential testing tool for electricians, has become an important ‘tool’ for us to test the performance

Mini Breadboard that is, ‘integrated circuit experiment board’, is a plug-in board, this ‘board’ has a number of small ‘socket (hole)’. When conducting circuit experiments, you can insert the pins and wires of electronic components into the corresponding holes according to the circuit connection requirements, so that they contact with the flexible contact reeds in

In the world of electronics fabrication and repair, the skill of ‘how do you solder wires to a circuit board’ is critical. Whether you are experimenting with simple circuits or assembling complex electronic devices, high quality soldering is the key to stable circuit operation! The cornerstone of a high-quality solder joint is thorough preparation. Please

PCB circuit board infrastructure is equivalent to a building’s foundation and framework, which consists of four main layers: top layer (Top Layer), bottom layer (Bottom Layer), inner layer (Inner Layer) and pad layer (Solder Mask Layer). Top signal layer (Top Layer)This layer as the PCB circuit board ‘front’, mainly for the layout of electronic components.

What is printed circuit board switches​?Printed circuit board switches​ is an electronic component used to control circuit on/off, function selection, etc. It is one of the more common components on circuit boards. A switch consists of a single contact and a number of linked contacts, which can be operated to connect or disconnect multiple sets

In the PCB circuit board printing process, the transformation of a bare board into a finished product with clear circuit graphics requires a series of sophisticated physical and chemical reactions, collectively known as pcb etching. Specifically, the process begins by pre-coating the outer layers of the board with a lead-tin alloy resist layer on the

Photoresist pcb boards are printed circuit boards manufactured using photoresist technology.The photoresist used in Photoresist pcb boards is a light-sensitive material that is usually applied to the surface of the board in the form of a layer of photosensitive resin. In the production process of circuit boards, UV light is projected onto the photoresist, which

Active components are key components in electronic circuits that can be powered from an external source to perform functions such as signal amplification, conversion, and generation. Active high frequency components are usually semiconductor devices such as diodes and transistors that perform active operations such as amplifying, rectifying and converting current. Simply put, active devices are

What is a protoboard?A protoboard, also known as a ProtoType board, is essentially an early sample of a product that is designed to test a design idea and see if it works. While most prototypes are made just to test basic user functionality, PCB prototypes need to be functional in some way, as they are

Crazing pcb is the phenomenon of cracks or breaks in a circuit board, which can lead to impaired functionality or even complete failure of the board. The causes of crazing pcb analysis: In order to prevent crazing pcb, you can take the following measures: Preventing crazing pcb requires a multifaceted approach that includes selecting materials,

Selecting the right PCBA process is a strategic decision that can have a decisive impact on product quality, productivity and cost-effectiveness. In the face of a wide range of process options, it is important to consider several key factors to ensure that the selected process can fit the product requirements, while adapting to production conditions

The tin spraying process, also known as hasl, is a long-established technology for PCB (Printed Circuit Board) surface treatment. The process starts by immersing the PCB in molten solder, which is then applied to the copper surface, followed by the use of a hot air gun to blow away the excess solder material, resulting in

A board electronics with holes is a substrate used for the layout of electronic components and its function is to connect electronic components. It is a design element on a circuit board, which is a hole set up to facilitate the insertion, connection and soldering of circuit board components. The core principle behind the functioning

A circuit board enclosure is a material specifically designed to protect circuit boards from damage or contamination. It also enhances the mechanical strength and thermal resistance of the circuit board, ensuring that it is more robust and trustworthy. Choosing the right enclosure is an integral part of the design process as it directly affects the

A 6 layer pcb stackup structure is a design in which six layers of conductive and non-conductive materials are stacked together during the circuit board manufacturing process to achieve complex circuit connections. This type of structure is commonly used in electronic products that require high-density wiring and multifunctional integration. Common 6 layer pcb stackup: 2.GND-SIG-GND-PWR-SIG-GNDIt
