Now let’s learn about another 3 common rules: 3W/4W/10W Rule, Overlap of Power and Ground Planes Rule, and 1/4 Wavelength Rule.

Today we will start to learn about the principles and tips for high-frequency-speed PCB routing. Let’s start from 3 common rules: 1.PCB Design Routing Basics 2.5-5 Principle 3.20H Principle

Now we will learn about the last role of red ink test in PCB——Detecting PCB Surface Cleanliness.

Here is our new product with black solder mask and immersion gold technique, it will be sent to our customer in Europe

Today we will continue to learn about the influence of red ink test in PCB manufacture. Detecting Solder Joint Integrity. Detecting Solderability.

Today we are going to talk about a testing method in PCB manufacture: Red Ink test.

Now I will show you 3 figures below, to help you better understand the difference between DRC and DFM.

Today, we send out a new kind of product, which is used in industrial control equipment.

This table above is the difference and compare between DRC and DFM, we could see more clearly in this table.

In this article, let’s continue to introduce the second check: DFM check.

In the PCB design and manufacturing industry, after engineering designers complete the PCB design, they need to conduct a series of checks to ensure the correctness and manufacture ability of the design. These checks are crucial to ensure that the PCB design meets specific specifications and manufacturing requirements.

Today We have a new product which is design for high-speed server, it also use HDI and immersion gold technique.
