A High-Frequency PCB Requires the Use of Specialized Materials

Special materials are required to achieve the high frequency provided by this type of printed circuit board – any changes in the Er value of these materials can affect the impedance of the board. Many PCB designers turn to Rogers dielectric material for its lower dielectric loss, reduced signal loss, lower cost of circuit fabrication and better suitability for fast-turnaround prototyping applications.

Apart from choosing the appropriate PCB material and determining the correct the value of the Er, designers should take parameter such as conductor width and spacing, substrate constant into consideration. These parameters must be exactly specified and implemented with the highest level of process control.

If you’re in a fast-moving industry, you need to know about high density interconnect printed circuit boards. If your company isn’t using them now, they probably will be soon. If they aren’t, you can be sure your competitors are using them, so you need to learn about HDI PCBs and their benefits fast.

High density interconnect PCBs are a way of making more room on your printed circuit board to make them more efficient and allow for faster transmission. It’s relatively easy for most enterprising companies that are using printed circuit boards to see how this can benefit them.

High density interconnect (HDI) PCBs represent one of the fastest-growing segments of the printed circuit board market. Because of its higher circuitry density, the HDI PCB design can incorporate finer lines and spaces, smaller vias and capture pads, and higher connection pad densities. A high-density PCB features blind and buried vias and often contains microvias that are .006 in diameter or even less.

Key HDI PCB Benefits

The evolution of high-density PCB technology has given engineers greater design freedom and flexibility than ever before. Designers using HDI high density interconnect methods now can place more components on both sides of the raw PCB if desired. In essence, an HDI PCB gives designers more space to work with, while allowing them to place smaller components even closer together. This means that a high-density interconnect PCB ultimately results in faster signal transmission along with enhanced signal quality.

HDI PCB is widely used to reduce the weight and overall dimensions of products, as well as to enhance the electrical performance of the device. The high-density PCB is regularly found in mobile phones, touch-screen devices, laptop computers, digital cameras and 4G network communications. The HDI PCB is also prominently featured in medical devices, as well as various electronic aircraft parts and components. The possibilities for high-density interconnect PCB technology seem almost limitless.

HDI PCB Applications

HDI PCBs are appropriate for a wide range of industries. As mentioned above, you’ll find them in all types of digital devices, like smartphones and tablets, where miniaturization is key to the effective application of the product. You can also find high-density interconnect PCBs in automobiles, aircraft and other vehicles that rely on electronics.

One of the most critical areas where the high-density PCB is making huge inroads is in the medical arena. Medical devices frequently need small packages with high transmission rates that only HDI PCBs can supply. For example, an implant needs to be small enough to fit in the human body, but any electronics involved in that implant absolutely must efficiently allow for high-speed signal transmission. Here, the HDI PCB indeed is a godsend. HDI PCBs can also be useful in other medical equipment, like emergency room monitors, CT scans and much more.

Prototype PCB Service vs. Standard PCB Service

Use PCB Prototype service when you want:

• Boards for Design Review or Preproduction Quality Testing

Our PCB prototype service is the perfect way to make sure there are no errors in your design before moving into mass production.

• Rapid PCB Turnaround

Rapid PCB prototyping means you get your boards fast.

• Boards with Eight or Fewer Layers

Because we are trying to get your boards back to you as fast as possible, we offer rapid PCB prototyping for boards with no more than eight layers.

• FR-4 Boards

Your printed circuit board prototype will come on standard FR-4 material.

• Quality Standard IPC1 Boards

Use Standard PCB service if you need:

• Boards for Full Production

Once you know that your design works, you can contact us for standard PCB service for full production for use in your applications.

• Slightly Longer Turnaround Time

Since these are the boards you will actually be using, it takes a little longer to make sure we get everything just right. However, now that you have tested the design, you can go right into your projects once you get your boards.

Boards with Up to 9-32 Layers

We have much more flexibility with materials and layers once we have the time to develop your full boards.

• FR-4, Aluminum, Flex or Other Special Types of Boards
• Quality Standard IPC2 Boards

What Are the Benefits of Circuit Board Prototyping?

We recommend you PCB prototyping service for function testing of new products prior to making a commitment to a full-production run. Benefits of developing PCB board prototype include:

• Rapidly test and correct designs if there is any mistake

After waiting over a week for your full boards, you’ll be eager to get them going in your applications. When you test your design beforehand with PCB prototypes, you can do just that.

• Potentially detect any design flaw in the early stages of your projects

The time to find out mistakes in your design is not when you have a full production run in your warehouse. PCB prototyping service allows you to spot any design problem in a few days, make adjustments and perfect the design before ordering your full run.

• Order low-quantity production runs featuring a MOQ of only five boards if necessary

Save money and reduce risks by putting off your big orders until you know you have the type of boards you want.

• Benefit from lower production tolerances

It offers a clear indication of how well your PCB will perform.

Once your proto boards have demonstrated their ability to meet your quality and performance requirements, you are ready for a full production run. Then we will transition from PCB prototype board service to Standard PCB service, which provides tighter production tolerances and more advanced options, including a free Design for Manufacture (DFM) check that is capable of detecting potential issues that could reduce the quality of your PCB.

While it may be tempting to simply order your full printed circuit boards and decide you’ll deal with all design flaws that arise as they come, it’s rarely the most efficient solution. You may get the boards out sooner, but if something goes wrong, it could prove to be a lot costlier and more time-consuming than taking an extra few days to test a prototype.

Save Time and Money in the Long Run With PCB Rapid Prototyping Services from HighqualityPCB

PCB prototyping is the best practice method used world-wide to verify the quality of a design before proceeding. In the past, some companies may not have had time to develop a prototype PCB, wait for the assembler to put that PCB prototype together and then test it. However, thanks to the rapid PCB prototyping offered by HighqualityPCB, this is no longer an issue. You can send in your prototyping PCB board design and have a fast PCB prototype in a week or less, giving you plenty of time to test your PCB proto board to fully prepare for your regular production run.
