PCB lamination is a key process step in the manufacture of multilayer printed circuit boards (PCBs). In this process, multiple thin, pre-processed circuit board layers (including copper foils, insulating substrates, leadframes, etc.) are tightly bonded together under high temperature and pressure with a specific adhesive (usually epoxy) to form a monolithic multilayer structure. The purpose
Agnetic environments and the control of interference with other equipment. ESD protection is the key to ensure that the equipment is not damaged in the electrostatic environment. This article will delve into the role of capacitors in enhancing EMS performance and the key function of resistors in preventing ESD damage. From the perspective of EMS
Static electricity arises from the separation of charges that occurs when two different materials come into contact with each other or are rubbed together, causing an object to become electrically charged as a whole. For example, the constant friction of people wearing clothes, or even the simple act of tearing paper, can trigger the generation
What is pcb panelization?PCB panelization refers to the process of integrating several small PCB boards into one large board by the manufacturer. From the initial stage of PCB design until the final production link, the board assembly operation always plays a pivotal role. It is not only about the quality of the PCB board to
Perforated sheet, as an important industrial material, is widely used in many fields such as construction, electronics, machinery and so on. It is characterized by having evenly distributed holes on the surface, which can not only play the role of aesthetic decoration, but also have practical functions such as air permeability, sound insulation and filtration.
In the PCB manufacturing process, pcb warpage problem has been one of the key factors affecting product quality and productivity. Warped PCB boards are not only difficult to subsequent assembly and soldering, but may also be rejected because they do not meet the specifications, leading to increased production costs and delivery delays. In order to
Circuit board side plating, also known as edge copper plating, refers to copper plating applied to at least one of the side edges of a PCB board that extends from the top to the bottom of the board. This process is designed to enhance the robustness of the PCB connection and reduce the risk of
PCB Copper Layup is the process of filling areas of a PCB board that are not wired or unused spaces with solid copper skins. Copper plays multiple key roles in PCB design including, but not limited to, reducing ground impedance, enhancing interference immunity, connecting to ground to reduce loop area, and promoting heat dissipation. Copper
In the electronics manufacturing industry, fusible PCB, as a special type of printed circuit board, has gradually attracted market attention in recent years.

On a printed circuit board,board pitch refers to the distance between two pins or components,which is usually measured in millimetres. The correct layout of components is essential in the design of a circuit board.A smaller pitch means that the components are closer to each other,which makes the design more compact,but correspondingly more difficult to manufacture.Conversely,if
What is beveler in pcb?The PCB beveling machine is a specialised equipment for chamfering the edges of circuit boards.Beveling of circuit boards refers to a special treatment on the edges or corners of circuit boards, which is usually done by cutting or grinding to make the edges that are originally straight or sharp rounded. This
In the electronics manufacturing industry,wave soldering, as an important connection technology, is widely used in the assembly process of circuit boards.
