Advantages of Metal Core PCB

Metal-based copper-clad laminates were born and developed in response to the rapid advancement of production and manufacturing technology in the electronics industry. As early as the early fifties, Japanese thick film research experts put forward the idea of this process design. It was not until 1969 that the manufacturing technology was practically applied. Metal core pcb The copper substrate […]

Corroded copper on PCB manufacturing

The process from the light board to show the line graphics is a more complex physical and chemical reaction process, now the typical process of PCB processing using the “graphic plating method”, the need to retain the line graphics to protect, and then the next step in the etching. corroded copper The practice is to pre-plate a layer […]

What is Copper Balancing?

PCB fabrication is the process of building a physical PCB from a PCB design according to a set of specifications. Understanding the design specifications is very important because it affects the manufacturability, performance, and production yield of the PCB. PCB refers to printed circuits board, printing wiring board(PWB). One of the important design specifications to follow is “balanced copper” in PCB […]

Soldermask in PCB production

PCB solder mask layer, refers to the printed circuit board to be on the part of the green ink. Soldermask windowed position is not on the ink, exposed copper to do surface treatment after welding components position, not windowed position are printed on the ink to prevent line oxidation, leakage. PCB solder mask open window for three reasons1. […]

PCB Etching Process and Precautions

PCB etching process is an essential part of the production of PCB, it is through a chemical reaction that will not cover the copper layer corrosion, thus forming the circuit board on the line required. PCB printed circuit factors affect the characteristics of the etching solution, a choice of etching solution etching solution selection is very important, it is so […]

Development and Processes of IC Carrier PCB

IC carrier board has a new technology in recent years, as a high-end PCB board, with high density, high precision, miniaturization, and thin features. IC carrier board is also called packaging substrate, in the field of high-level packaging, IC carrier board has replaced the traditional lead frame, and become an indispensable part of the chip package, not only for the […]

PCB: Plated Vias

Plating sealing holes is a commonly used manufacturing process for printed circuit boards, used to fill and seal through-holes (vias) to enhance conductivity and protection. In the printed circuit board manufacturing process, the vias are used to connect the different circuit layers. The purpose of plating to seal vias is to enhance conductivity and provide […]

PCB Solder Mask

Solder mask(solder resist) is used to provide media and mechanical shielding during and after the soldering process. Solder masks are used to provide dielectric and mechanical shielding during and after the soldering process. The material of the solder resist can be liquid or dry. Colors of PCB Solder maskPCB solder mask can be displayed in […]

Development prospect of IC carrier boards

IC carrier board, also known as packaging substrate, connects and transfers the bare chip (DIE) and the signal carrier between the PCB, which can be understood as a high-end PCB product. IC carrier board compared to the PCB has higher technical requirements. IC carrier board From the development of HDI (High-Density Interconnect) technology, from the […]

What is FPCB?

Flexible circuit boards are highly reliable, excellent flexible printed circuit boards made of polyimide or polyester film as a base material. Abbreviated as flexible board or FPC, it is characterized by high wiring density, lightweight, and thin thickness. It is mainly used in cell phones, notebook computers, PDAs, digital cameras, LCMs, and other products. Production […]

PCB Drilling Dimensions

Via is one of the most important parts of a multilayer PCB, and the cost of drilling usually accounts for 30% to 40% of the cost of PCB fabrication. From the design point of view, a via is mainly composed of two parts, one is the middle of the drill hole (drill hole), and the […]
