Stack-up Design in PCB

In general, PCB stack-up design mainly follows two rules:1. Each trace layer must have an adjacent reference layer (power or ground layer);2. Maintain a minimum distance between the adjacent main power layer and the ground layer to provide a large coupling capacitance; The following is an example to explain the stack-up from two-layer board to eight-layer board:I. Stack-up of single-sided PCB boards and double-sided PCB boardsFor two-layer boards, the problem of lamination is no longer due to th...

Impedance Matching in HDI PCB Design

Impedance matchingImpedance matching means that when source is transmitted, the load impedance must be equal to the characteristic impedance of the transmission line. At this situation, the transmission will not reflect, which indicates that all source is absorbed by the load. Conversely, there is source loss during transmission. In HDI PCB design, impedance matching is related to the quality of the signal.When do PCB traces need impedance matching?It does not mainly decided by the frequency, bu...

Important Processes of Rigid-Flex PCB Manufacturing

Introduction:Flexible printed circuit boards are used in a wide range of applications, almost all types of electronic products are involved, and the emergence of rigid-flex PCBs for the complex electronic packaging interconnection provides a better way to produce perhaps the most complex interconnection structure of the PCB products. The rigid-flex PCB includes two technologies what are the flexible printed circuit board technology and the rigid printed circuit board technology. For example, by ...

7 Tips in Designing PCB

1. Flexible application of via designFor high-voltage, high-current, high-power, and high-heat components, the layout of components should be as loose as possible when designing printed boards. The size of the component pads and the pad spacing of each solder pin can also be designed bigger. If the number of circuit components and the size of the printed board allow, you can also design some vias in the space between the pads of the components and the copper foil of the printed board according t...

Embedding of Passive Components into Flex PCB

Introduction:Miniaturization and multi-function of products are the main driving force for the development of electronic industry. Printed circuit board is the most common electronic assembly platform. These include rigid or flexible polymer substrates and ceramic substrates for metal wiring. Typically, various components and subsystems are mounted on the board surface. However, in order to reduce the number of components on the surface of the printed circuit board, researchers are constantly st...

Semi-Flex PCB

Introduction:Traditional rigid-flex PCB materials include rigid materials and flexible materials. The current production method is usually to carry on the pattern plating for the rigid substrates and flexible substrates, and then laminating the rigid substrates and flexible substrates together by using the adhesion agent. The materials of the adhesion agent are usually made of non-flowing prepregs. Flexible materials are expensive and costly to make. At present, the cost of multilayer rigid-flex...

How does Arduino detonate the world of open-source hardware makers?

In addition to having a strong hands-on ability and a passionate heart, Maker also has a must-have skill – “Arduino Board”. From grotesque hardware gadgets to tens of millions of dollars in commercial products Pebble smartwatches and Makerbot 3D printers start with such an inconspicuous Arduino board. "Fifty years ago, people who wrote the software needed to wear a white apron to know everything about semiconductors. Now? Even my mother can program."

How to achieve PCB automatic routing efficiently?

1. Determine the number of layers of the PCBBoard size and the number of routing layers need to be determined early in the design process. If the design requires the use of high-density ball grid array (BGA) components, the minimum number of routing layers required for routing these devices must be considered. The number of routing layers and the stack-up method directly affect the routing and impedance of the printed routing. The size of the board helps determine the stacking and line width to ...
