In circuit board design, we are usually very concerned about the quality of the signal, but sometimes we usually limit the research on the signal line, and the power and ground as the ambition of the situation to deal with, although this can make the ques
What is the circuit and load impedance? Whether there is space to place magnetic beads on the PCB board. The first three can be judged by observing the impedance frequency curve provided by the manufacturer.
PCB production process is more complex, it involves a wide range of processes, from simple machining to complex machining, there are ordinary chemical reactions and photochemical electrochemical thermochemistry and other processes, computer-aided design C
From passive components to active components and integrated circuits, all eventually become surface mount devices (SMDS) and can be assembled by pick-up and drop devices. For a long time it was thought that all pin components could eventually be packaged
Whether the edge of the outer frame of the power supply layer in the multi-layer board is reduced, such as the copper foil of the power supply layer is exposed outside the board, which is easy to cause short circuit.
With the development of the electronics industry, the demand for printed boards is getting higher and higher. Printed board design of high density, thin wire, small aperture trend faster and faster, printed board production process is becoming more and mo
In this environment of multi-project concurrency, high technology, rapid change, and limited resources, failures and setbacks are common. As companies are always struggling to meet changing market demands and face various challenges, they need to consider
Customers place orders to PCBA processing plants according to their actual needs and put forward specific requirements. The processing plant will evaluate its capacity to see if it can fulfill the order. If the manufacturer is sure that they can complete
The process does not require specialized technical personnel to operate, operators only need to go through simple training, and in the operation, only need to pay attention to the general chemical reagent operation safety can be. In terms of environmental
Halogen PCB circuit boardHalogen refers to the halogen elements in the periodic table of chemical elements, including fluorine (F), chlorine (CL), bromine (Br), and iodine (1). At present, flame retardant substrates, such as FR4, CEM-3, etc., are mostly b
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.
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
