PCB design how to do crystal layout?

Do not wire under the crystal oscillator to ensure that the floor is completely paved, and do not wire within the 300mil range of the crystal oscillator, which can prevent the crystal oscillator from interfering with the performance of other wiring, devic

Four suggestions for PCB design from the point of view of drawing board

t present, in PCBA processing, the introduction of advanced testing equipment for quality control of the production process. In the process of reflow welding, AOI testing equipment is generally used for quality control.Can provide the smallest package 020

Why can't the signal line be changed multiple times in high-speed PCB design?

Our conclusion above is that it's better to go through a bigger hole. At this point, we need to introduce you to two formulas. One is the calculation formula of the parasitic capacitance through the hole: C=1.41εTD2/ (D1-D) The other is the calculation fo

What does a multi-layer PCB look like? High-end PCB board design process

Layout engineers think about it! No longer afraid of not painting!Think about purchasing want to cry, more than 10 times more expensive than ordinary through hole plate! Therefore, only products like the iPhone are willing to use. Other phone brands, no o

High Speed PCB design Ten tips for PCB lamination design

The classic PCB laminated design is almost all even layers, rather than odd layers. Even layers of printed circuit boards have cost advantages, and even layers can avoid board warping more than odd layers.

PCB design layout constraints

The layout of the components should be convenient for signal flow, so that the signal is as consistent as possible. In most cases, the flow direction of the signal is arranged from left to right or from top to bottom, and the components directly connected

Reasons for internal shrinkage design of GND layer and power layer in multi-layer PCB design

the power plane should be inside the PCB, and the upper and lower layers adjacent to him are 0V planes, and the distance between the two 0V flat faces should be at least 20 times the distance between them and the power plane.

What is the meaning of "false eight layers" in PCB design?

This line width is generally satisfied for the conventional design, then we can compare the two layers, you will find that the difference between them is that the core is thinner, and then the pp sheet of one or two layers and five or six layers is also t

Requirements for screen printing design in PCB design

when the customer requires the top bottom to write copper words, line copper word line width: HOZ base copper: character width of more than 8mil, height of more than 45mil; 1OZ base copper: more than 10mil character width; Height above 50mil. At the same

PCB design common wiring rules

Design data output: PCB source files, Gerber files, assembly files, steel mesh files, structural files, etc. After the PCB Layout design is completed, our engineers will conduct mutual inspection, including DFM inspection, QA inspection, EMC inspection. A

PCB process edge function, production method and design

This layer of organic film can make the circuit board before welding to ensure that the inner layer of copper foil will not be oxidized, welding, once heated, this layer of film will evaporate, solder can solder the copper wire and components togethe

PCB base board design principles

in the board frame, to determine the positive and negative, it is best to place all devices on the same side, which is marked with three XXX, as shown in the figure below.

Just upload Gerber files, BOM files and design files, and the KINGFORD team will provide a complete quotation within 24h.
