How to make your PCB design better

Posted on March 06, 2019 by G

Many people think that the work of PCB Layout is very boring. Every day, thousands of wires are routed to the board, and various packages are repeated, and the work of pulling the wires is repeated. However, designers must make trade-offs between various design rules, taking into account performance, cost, process and other aspects, but also notice that the layout of the board is neat and tidy, not as simple as it seems, and requires more wisdom. Let's talk about developing some good work habits during design, which will make your design more reasonable, easier to produce, and better.

Common problems and solutions in high speed PCB design

Posted on February 27, 2019 by G

Although the high-speed simulation tools and interconnect tools at this stage can help designers solve some of the problems, high-speed PCB design also requires the accumulation of experience and in-depth communication between the industry.

Use of high speed PCB vias

Posted on February 27, 2019 by G

The via design consists of a pad and a pad area around the hole and an inner electrically isolated area. The parasitic inductance, parasitic capacitance, etc. of the vias affect the high-speed signals passing through the vias. The size of the vias and the pads connected to them have a direct effect on the properties of the vias.

Characteristic impedance of PCB in high speed design

Posted on February 19, 2019 by G

In high-speed designs, the characteristic impedance of the controllable impedance plates and lines is one of the most important and common problems. First, let's look at the definition of a transmission line: a transmission line consists of two conductors of a certain length, one for transmitting signals and the other for receiving signals (remember that the "loop" replaces the concept of "ground"). In a multi-layer board, each line is part of the transmission line and the adjacent reference plane can be used as a second line or loop. The key to a line becoming a "perfect" transmission line is to keep its characteristic impedance constant throughout the line.

Design performance requirements for PCB multi-layer

Posted on October 27, 2025 by G

The design performance of multi-layer boards is mostly similar to single-panel or double-panel, which is to avoid avoiding too many circuits to fill too small space, resulting in impractical tolerances, high inner layer capacity, and possibly even dangerous products. Quality safety. Therefore, the performance specification should consider the complete evaluation of the thermal shock, insulation resistance, welding resistance, etc. of the inner layer. The following sections describe important factors that should be considered in the design of multilayer boards.

Signal integrity and characteristic impedance of the device

Posted on November 13, 2025 by G

Signal integrity issues can cause problems when you struggle to stabilize the various signals on the board. The IBIS model is an easy way to solve these problems. You can use the IBIS model to extract some important variables for signal integrity calculations and finding solutions for PCB design. The various values you extract from the IBIS model are an integral part of signal integrity design calculations.

Signal Integrity Research: What is Signal Integrity?

Posted on October 14, 2025 by G

If you find that the design experience accumulated in the previous low-speed era does not seem to work now, the same design, no problem before, but now can not work, then congratulations, you have encountered the core problem in hardware design: signal integrity . It is a good thing for you to meet one day earlier.In the past low-speed era, the signal rise time is longer when the level jumps, usually a few ns. Interconnects between devices do not affect the functionality of the circuit, and there is no need to care about signal integrity issues. But in today's high-speed era, with the increase in IC output switching speed, many are in the picosecond level, and almost all designs have encountered signal integrity problems regardless of the signal period. In addition, the pursuit of low power makes the core voltage lower and lower, 1.2v core voltage is already very common. Therefore, the noise margin that the system can tolerate is getting smaller and smaller, which makes the signal integrity problem more prominent.

PCB through hole (Via) introduction

Posted on January 24, 2019 by G

Via is one of the important components of a multi-layer PCB. The cost of drilling is usually 30% to 40% of the cost of PCB board. Simply put, each hole in the PCB can be called a via. From the perspective of function, the vias can be divided into two categories:
