High density interconnect (HDI) is a technology that is becoming prevalent in PCB design and integration into electronic products of all kinds. HDI is a technology that provides for a much denser construction on a board by the ability to place increasingly smaller components in closer proximity, which also results in shorter paths between components. The evolution of high density PCB technology has given engineers greater design freedom and flexibility than ever before.

HDI PCBs are finding their way into a growing number of products:

•      Smartphones and Computers  – intelligent mobile phones ,tablet computers and other wearable devices are taking full advantage of smaller profiles, reduced weight, and increased functionality, made possible through the integration of HDI circuits.

•      Communications devices and Medical equipment – smaller space requirements and light weight are ideal for such applications. Diagnostic and monitoring equipment has become more reliable and expanded with technical features that aid medical teams with patient treatment, powered by HDI PCBs and advanced software.

HDI PCBs Benefits

HDI boards utilize buried or blind vias, or a combination, and may also incorporate micro vias with an incredibly small diameter. This facilitates the incorporation of more technology in less space, with fewer layers. Multi-layer HDI boards are also in common use, with many layers being accommodated through various construction methods utilizing blind, buried, stacked, and staggered vias.

With smaller components and blind via and via in pad technology, components may be placed closer together, resulting in faster signal transmission rates while also reducing crossing delays and signal loss. These are key considerations that generate improved performance of HDI PCBs.

HDI boards are preferred for applications where space, performance, reliability, and weight are concerns. This makes them more suitable for nearly every application related to electronics, consumer products, computers, and aeronautics.

Multi-layer HDI boards can provide strong interconnection of stacked vias, resulting in high levels of reliability, even in more extreme environments.

HDI PCBs Considerations

Although the benefits of HDI are considerable, there are drawbacks to the technology, as well.

Specialized processing and equipment required to manufacture HDI boards is expensive. Such equipment includes laser drills, laser direct imaging processes, and other specialized fabrication equipment and materials. This need for specialized equipment and operator training is partially accountable for the higher cost of HDI fabrication.

Attention to detail is critical in the design and manufacturing of HDI printed circuit boards. This requires expertise and experience.

Many fabricators have not made the investment or transition to laser direct imaging (LDI) for board fabrication. In the case of HDI boards, the tight tolerances for finer lines and tighter spacing make LDI an important consideration in quality results. While contact imaging is still widely used in PCB manufacturing, LDI is much more preferable for HDI boards, although the expense for the equipment can be considerable.

HDI PCBs Quality

Over the course of a decade in business, PCBAStore has established a hard-earned reputation for manufacturing PCBs of the highest quality. Our custom PCB manufacturing capabilities enable you to get the finest quality HDI PCBs at competitive prices without min order quantity requirement. Our team run design for manufacture check on your custom PCB file and consult with you to ensure it is ready for manufacturing and that your boards will meet your performance requirements. We also have an on-site quality control department to verify the finished product meet your high quality standards.

We're capable of manufacturing HDI PCB up to 40 layers in various structures.

For HDI PCB production price, please send your PCB file (Gerber format of file preferred) & requirements to [email protected], we'll quote ASAP.

When we design an electronic project, usually we will need to make some samples to test to make sure our design is right, then we can increase the production quantity to get a good price and have a good sale on market.

Problems come out now, for low quantity production will have much higher unit cost compare to the batch production, it will need us to invest much money at the beginning and bare much risk too.

As we all know, China is a manufacturer center of electronic products, especially in Shenzhen.

We have a project at the beginning in 2018, at that time, I try to find a PCB supplier in Shenzhen to supply us one turn-key service.

Below is some information I get from PCBASTORE sales Peter Lee, we will be happy to share their information here:PCBASTORE founded 12 years yet, has rich experience in PCB industry，during our long terms cooperation with our customer, we find many customers will meet below trouble: MOQ requirement, high set up SMT charge, many extra parts required then actual need parts quantity, which leading the sample cost to be very high.

To help customer to finish low quantity order, PCBASTORE builds professional Team to do low quantity PCB order for most start-up companies.

With the rapid development of the market economy and technological innovation, the rise of the electronic product industry has become an inevitable trend of social development and has been widely applied and become a leading industry.

Before manufacturing your PCB (printed circuit board) board, you need to finish your schematic diagram and PCB design and convert the PCB file into Gerber file, if you need PCB assembly service, also you need to complete the BOM list.

Secondly, find the manufacturers of PCB.

Since the globe is flooded with too many PCB services providers, it's a hard job to settle on a long-term PCB fabricator.Though PCB manufacturing and assembly contain so many links that should be carefully inspected one by one, the process mainly centers on Products (quality, industries, and cost), Capabilities and Service.

Send your PCB file or Gerber file to them for inquiry, then indicate the quantity you need and technological requirements of the board, such as the type and specification of the material, surface technology (such as  OSP, HASL-with lead, HASL-Lead free, immersion gold, etc.

), the color of characters and solder mask, etc.
