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 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 […]
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 […]
Conformal coating is a specially formulated coating, used to protect circuit boards and related equipment from the erosion of the bad environment, also known as “circuit board protection coating”. Conformal coating has good resistance to high and low temperatures; it’s curing into a transparent protective film, with superior insulation, moisture, leakage, shock, dust, corrosion, anti-aging, […]
PCBs used in harsh and extreme environments mean that they need to operate under extreme temperatures, humidity, constant vibration, strong shocks, and other conditions that can affect reliability and their normal performance. Due to the differences in environmental requirements across industries and applications, in the medical industry, this could mean conditions such as high temperatures, […]
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 […]
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 […]
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 […]
Impedance control, the conductor in the circuit board will be a variety of signal transmission, to improve its transmission rate and must improve its frequency, the line itself, if due to etching, the thickness of the laminated layer, the width of the conductor and other factors that will cause impedance worth of change, so that […]
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 […]
FFC connector is a flexible flat cable connector, it is a PET insulation material and extremely thin tinned flat copper wire, through a high-tech automated equipment production line pressed together into a new type of data cable, with a soft, free-to-bend and fold, thin thickness, small size, simple connection, easy disassembly, easy to solve the […]
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 […]
