Legend Printing- PC Board Fabrication Process

If you’re looking for the most advanced and efficient PCB manufacturing process on the market, look no further than the legend printing-multilayer PCB manufacturing process. This new process is revolutionizing how printed circuit boards are manufactured, offering superior performance and reliability over traditional methods. In this article, we will discuss the benefits of this new process, how it works, and why it’s the best choice for your PCB manufacturing needs.

The legend printing of multilayer PCB is revolutionizing the way printed circuit boards are made. This cutting-edge manufacturing process is making it possible to create circuit boards that are more reliable, cost-effective, and easier to use than ever before. With this process, legend printing can provide customers with superior circuit boards for a wide range of applications.

What Is Legend Printing?

Legend printing is a specialized multilayer PCB manufacturing process that combines the benefits of advanced technologies such as laser direct imaging (LDI) and inkjet printing to produce high-quality printed circuit boards. The process creates layers of fine traces on the Printed Circuit Board, allowing for a high level of detail and accuracy, along with excellent signal integrity.

The key benefits of legend printing include increased resolution, trace widths down to 5 mils or less, a wide variety of solder mask and surface finish options, and minimal time required for prototyping and production. This makes it an ideal choice for high-density designs where reliability and performance are important.

The process starts with laser direct imaging (LDI), which involves a laser beam used to create the desired pattern on the PCB’s surface. Next, an inkjet-printed layer is applied to the board before it is processed through the reflow oven. Finally, a solder mask is applied and cured, providing a protective coating to the finished product.

Legend printing ensures a superior level of quality for multilayer PCBs, giving designers the confidence to push the boundaries in their design requirements. With its combination of advanced technologies, it’s a reliable and cost-effective solution for producing complex electronic components. It also offers quick turnaround times with many fabrication capabilities, including small batch sizes and quick turnarounds. It’s no wonder why many leading companies rely on this cutting-edge technology to get them from concept to market quickly and efficiently. Moreover, if you’re looking for top-notch prototype PCBs, you can’t go wrong with legend printing.

Inkjet printing has many benefits that other processes cannot match. It provides a quick turnaround, allowing projects to go into production quickly, and allows designers to produce from a single-layer board or up to 10-layer boards. It helps make use of acid-free and water-based inks that deliver rich blacks, sharp text, high gloss finishes, and precise graphics. However, these advantages can increase the printing price. Like, an inkjet printer starts at about $10,000 and requires a costly startup investment. When these costs are factored in with maintenance fees, servicing needs, and running costs like ink replacement, this solution could prove to be too pricey for many companies.

The Multilayer PCB Manufacturing Process

Legend printing involves an advanced automated production system to ensure consistent and reliable results for customers. Generally, the process starts with a substrate, which consists of several layers of epoxy resin-bonded copper foil. Manufacturers then use imaging equipment to print the design onto the substrate and etch away the excess copper.

Then, they apply a layer of insulation material over the etched copper layer, followed by the insertion of conductive vias which electrically connect the layers. Finally, a solder mask is applied to protect the board from any accidental damage.

Through a multilayer PCB manufacturing process, you can produce intricate designs with high levels of accuracy and repeatability. This helps to ensure that your product will perform as expected when it reaches its final destination. The versatility of a multilayer PC BOARD manufacturing process also means that you can work on a wide range of different products.

Some industries that use legend printing include automotive, telecommunications, and aerospace applications. Each of these markets demands unique requirements and specifications, but they all require reliability and dependability. To keep up with the demands of each industry, we have developed innovative solutions through our experience in research and development. For example, aircraft are very sensitive structures, so some companies offer low-volume and pre-production testing services using the RISC or a rapid prototyping service. With such a service, you can reduce the lead times for tooling; maintain quality control during assembly, and reduce the risk exposure during the production ramp-up time.

The Benefits Of Legend Printing

The Legend printing-multilayer PCB manufacturing process offers several benefits for businesses looking to create complex circuit boards. By using this process, industries can ensure very high quality and accurate production.

The first benefit of using this process is that it allows for smaller board components. By using a multilayer system, more complex circuits are easy to create on smaller boards. This makes the boards easier to package and transport, saving the companies time and money.

Moreover, by using the legend printing-multilayer PCB manufacturing process, businesses can produce boards with superior electrical performance. This process can achieve high levels of precision and accuracy, leading to fewer errors and better overall performance.

Finally, this process allows for faster turnaround times. By utilizing multiple layers of production, businesses can quickly assemble complex circuits and get their products to market faster. This ensures that companies remain competitive in their industries and are able to capitalize on market trends quickly.

Overall, the Legend printing-multilayer PCB manufacturing process is an excellent option for businesses looking to maximize efficiency and quality when creating complex circuit boards. By utilizing this process, you are confident that your products are of the highest quality and are produced as quickly as possible.

Engineers also use advanced testing and inspection techniques to ensure that every product is up to high standards of quality and performance. By hiring a good printing company, you can trust that your multilayer PCB will be delivered on time and meet all of your requirements.

What To Consider While Making Legend Prints

You have to consider a few things during legend printing, be it new or some modifications, such as:

• Texts should have the same orientation in the entire board, like reference designator, part numbers, brand details, etc. You should arrange the text from top to bottom.
• Manufacturers often have to deal with overlapping texts that need editing. You can avoid it by moving the reference designator to the right side.
• Though you can add legend printing on both sides of the board, it becomes expensive. So, you can reduce the cost by using only one side.
• Markings should have standard shapes and colors to have readable and low-cost printing.
• You can reduce printing faults through measurements. Keeping the space a few mils can reduce the errors.
• Avoid placing text in four directions as it can make repair complex.
• The text should not overlap the holes or vias, or it will lose its significance.
• Try not to write the text on the fast signal paths, as it can cause dielectric loss, affecting the impedance level.

Legend printing involves different text styles, depending on the circuit board manufacturer and customers. Designers should check the styles before sending the Gerber files to fabricators.
