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
In the field of modern electronic manufacturing, the welding process is an important step to realize the functions of electronic equipment. In the welding process, soldering pins, as one of the core tools, undertake multiple functions such as connection, testing, and signal transmission. In the welding process, soldering pins, as one of the core tools,
HDI technology is a cutting-edge PCB (Printed Circuit Board) manufacturing process that offers the significant benefits of high-density layout, high reliability and high integration, with the PCB serving as the cornerstone of electronic component interconnectivity, carrying and solidly connecting all types of electronic assemblies. Through the application of high-density integration HDI technology, can promote the
Allflex PCB, also known as Flexible Printed Circuit Board (FPC), is a type of circuit board that can be completely bent. Folded or curled circuit board. It consists of one or more layers of polyimide film as a substrate, covered with a copper foil layer and a cover film, and the circuit pattern is formed
What is the bend radius of a flexible circuit board? The bending radius of a Flexible Printed Circuit Board (FPC) refers to the fact that when the FPC is bent, the two sides of its centre line are subjected to different types of stress, pressure on the inside and tension on the outside. The magnitude
The stacked construction technique of HDI circuit boards allows multiple circuit layers to be interconnected by means of precisely tuned blind and buried vias, which are significantly smaller in diameter than the through-holes found in conventional PCBs. This fine interconnect mechanism not only reduces board size, but also significantly increases routing density, allowing more electronic
ELIC PCB is one of the HDI products, the full name is every layer interconnection, is the highest end of the HDI products. ELIC boards are commonly stacked for 8 to 14 layers. Any layer interconnection (ALIVH) technology, as the name suggests, is a multi-layer printed circuit board (PCB) can be achieved in any two
Circuit board labels are the PCB (Printed Circuit Board, Printed Circuit Board) technology based on the manufacture of high-frequency RFID tags. PCB tags can be divided into a variety of types according to power, size, frequency and other factors, according to the frequency distinction between ultra-high-frequency PCB anti-metal tags, high-frequency PCB anti-metal tags and so
