Nickel gold is a kind of surface treatment technology with large application. Remember: nickel layer is nickel phosphorus alloy layer, which is divided into high phosphorus nickel and middle phosphorus nickel according to phosphorus content.
HDI board technology is characterized by BuildingUpProcess, commonly used resin coated copper foil (RCC), or semi-cured epoxy glass cloth and copper foil lamination is difficult to reach fine lines.
Common impedance pcb circuit boardsDefinition of Impedance: In a circuit with resistance, inductance and capacitance, the hindrance to the current in the circuit is called impedance. Impedance is often represented by Z, which is a complex number. The real
Printed circuit boards are assembled electronic parts1. Printed circuit board (PCB)PCB is the abbreviation of Printed Circuit Board (Printed Circuit Board). Also known as printed circuit board, printed circuit board, because it is made by electronic print
How LED Printed Circuit Boards (PCBs) WorkAs the technology of the world continues to evolve, so does the technology in the field of LEDs, and LED Cases is a field that involves combining two technological approaches in order to come up with other methods
With the rise of the electronic industry, circuit board production and development has become a more and more important part of PCB proofing a circuit board is not simple, easy to say.
ircuit board defect detection includes two parts: solder spot defect detection and component detection. The traditional detection adopts manual detection method, which is easy to miss detection, slow detection speed, long detection time and high cost, and
In the past decade of research on PCB copying board and chip decryption, Hongyunlai reverse R&D engineers have accumulated rich experience in board copying and decryption, and have maintained long-term friendly cooperative relations with many domestic...
At the same time, it must be easily removed by flux quickly in the subsequent welding high temperature for welding. OSP process is simple, low cost, widely used in PCB manufacturers.
In order to suppress the cross talk between the printed circuit board wires, in the design of wiring should be as far as possible to avoid long distance equal wiring, as far as possible to open the distance between lines, signal lines and ground and power
Experienced power developers know that EMI suppression in the PCB design process can save a lot of time for EMI suppression design in the final process to the greatest extent. This article will explain to you the specification steps in PCB EMI design, int
Attention should be paid to the wiring of signal lines under magnetic beads, between pads and those that may come into contact with magnetic beads. Some magnetic beads conduct electricity quite well and may produce unexpected conductive paths.
