The selection of PCB surface treatment is not a simple process, and the use and working conditions of the PCB need to be considered. A suitable surface treatment should help meet the application of the PCB circuit as well as the manufacturing process.

PCSPCB one-stop PCBA manufacturers to talk about the number of PCB board on SMT processing what impact? The influence of PCB layer number on SMT processing efficiency and quality.

PCB power routing is a very important part of printed circuit board design. The quality of power wiring directly affects the stability and performance of the circuit. This article will introduce several PCB power wiring skills to help you better deal with power wiring problems when designing PCB.

Thick copper pcb can provide better electrical conductivity and heat dissipation and are suitable for applications with high power and high frequency circuits. Thick copper pcb design precautions.

The principles and techniques of PCB heat dissipation design are introduced to help readers understand how to optimize their PCB design to improve heat dissipation performance and system reliability.

Before a PCB board is put into production and ready for assembly, you must generate a set of documents to assist your manufacturer. These are your PCB design output files, also known as manufacturing files, manufacturing data, assembly files, etc.

Power PCB design is a key link to ensure the efficient and stable operation of electronic equipment. The following is a detailed arrangement of the main points of power PCB design

There are 15 common effects in PCB circuit design: suspension bridge effect, ripple effect, overshock effect, resonance effect, suspension effect, crosstalk effect, reflection effect, shielding effect, thermal expansion effect, ground hole effect, filling effect, temperature drift effect, crystal effect, limited effect, mine effect.

PCB impedance is the combination of capacitance and inductance of the circuit at high frequency operation, although it is also measured in Ω, but it is somewhat different from the resistance as a DC characteristic, the impedance is an AC characteristic, which means that it is related to the frequency, while the resistance is not.

Let's get started with some of the basic PCB design and manufacturing guidelines needed to ensure a successful design. And make sure your board is manufacturable.

PCB lamination needs to be considered from many aspects such as the number of layers, signal type, board thickness, material selection, copper thickness, impedance control, EMI/EMC shielding, thermal management, cost and testability.

Copper is to cover the idle space on the PCB with copper surface, all kinds of PCB design software provide intelligent copper laying function, usually the area of copper will turn red, representing this part of the area is covered with copper.

In PCB design, we often wonder whether the surface of the PCB should be covered with copper? This actually depends on the situation, first we need to understand the advantages and disadvantages of surface copper.

PCB flypin test is the use of 4 to 8 probes to the circuit board for high voltage insulation and low resistance conduction test, testing the open and short circuit of the line. The test stand is a special test fixture for the on-off test of the mass production PCB board. The production cost is higher, but the test efficiency is better, and the return order is free of charge.

Traditional designs strictly distinguish between analog and digital circuits, however, in high-speed digital-analog hybrid circuits, it is better to use multiple grounds and use large area power and ground planes to provide low impedance for power supply decoupling. And how to eliminate the interference between analog signals and digital signals has become one of the key points of hardware design.

With the continuous progress of Internet technology, many board manufacturers now have online pricing of PCB circuit boards. However, the determinants of PCB circuit board quotation mainly include the following aspects
