Ceramic semiconductor materials are made up of a range of compounds which mainly include metal oxides, nitrides and carbides. Among the common ceramic semiconductor materials, zinc oxide (ZnO), barium titanate (BaTiO3) and silicon nitride (Si3N4) occupy an important position. These materials are made by sintering ceramic raw materials under high temperature conditions. As a result
A circuit diagram is a pictorial representation of the connections of a circuit using graphical symbols and lines. It is a combination of specific symbols and lines that clearly shows how the electronic components Q are connected, where the current flows, and how the circuit works. Circuit diagrams can be divided into different types such
Active RF circuits are RF circuits that require an external power source to function properly. Such circuits usually contain components such as amplifiers, mixers, and voltage-controlled oscillators, and are capable of increasing the gain of the signal, modulating the frequency and amplitude of the signal, and are highly resistant to interference. Compared to passive circuits,

The hard drive printed circuit board is a key component of a hard disc. It consists of one or more layers of glass fibre substrates stacked on top of each other and covered with various electronic components, such as integrated circuits, connectors, capacitors, and so on. In the operation of a hard disc, the circuit
SMT high temperature soldering technology is a soldering method that uses peak soldering temperatures in excess of 220°C in the SMT (or Surface Mount Technology) process. This technique is typically implemented in the 245 to 247°C temperature range to ensure that the solder paste and the BGA (ball grid array) solder balls are able to
A cold solder joint is a soldering phenomenon that occurs when the required minimum wetting temperature between the brazing material and the base metal is not reached, or when the metallurgical reaction fails to proceed adequately despite the fact that wetting occurs in some localised areas. When this phenomenon occurs, it means that there is
PCBA (Printed Circuit Board Assembly) test fixture plays a vital role in the electronics manufacturing industry. Its main function is to provide physical support and electrical connection for the test link of PCBA, so as to ensure the efficiency and accuracy of the test. Whether it is consumer electronics, automotive electronics, or medical equipment, this
DIP package assembly, also known as Dual In-line Package (DIP), is an assembly method that requires the pins of an electronic component to be inserted into a through-hole of a printed circuit board (PCB), and then secured using soldering techniques such as wave soldering. The DIP package process is particularly suitable for larger electronic components
A phone circuit board is a key component used for the connection and assembly of circuits inside a mobile phone. It is usually a thin board made of insulating material covered with a conductive layer that is used to connect and support the various electronic components inside a mobile phone, such as processors, memory, sensors,
The use of teflon pcb laminate has increased dramatically recently. There are many reasons for this change. One of the reasons is the rapid development of the electronics industry and the increasing demand for high-frequency boards.What is teflon pcb laminateTeflon is a chemical substance that can be simply called polytetrafluoroethylene or PTFE. It is widely
PCB backdrill, also known as controlled depth drilling, is simply the process of drilling a hole from the back side of an already manufactured multilayer circuit board. However, this is not just playing, but to accurately trim some of the through-holes (we also call it PTH holes, that is, plated through-holes) in those unwanted ‘little
In the mass production of printed circuit boards (PCBs), manufacturers often combine multiple individual boards into one large board, a process known as boardmixing, where multiple small boards are combined into one large board. The aim is to feed these boards more efficiently into the automated machines of the SMT (surface mount technology) production line,
A pcb microscope is a microscope specifically designed to observe printed circuit boards (pcbs). In the modern electronics industry, pcb microscopes play a key role in helping engineers and technicians inspect and analyze tiny and delicate circuit structures in electronic devices. As a pcb manufacturer, efficient and reliable pcb quality control (QC), rework, failure analysis,
Hot plate for pcb soldering is an advanced soldering technique that is primarily used to securely attach electronic components to printed circuit boards (PCBs). This method utilises the heating function of the hot plate to provide uniform temperature control, thus ensuring an efficient and stable soldering process. The hot plate for pcb soldering process achieves
Parasitic resistances are resistances that are not intentionally designed into a circuit, but are created due to circuit layout or component characteristics, for example. They are usually unavoidable and affect the performance and stability of the circuit. Parasitic resistors have the following characteristics: Parasitic resistors are often considered the ‘enemy’ of circuit design due to
