PCB HDI Support
Despite the numerous advantages of HDI technology, fitting a lot of advanced features into a small space presents challenges to the PCB fabrication process. Using a variety of design techniques and materials, designers must carefully plan their designs to ensure the function and manufacturability of their circuit boards before sending them to be fabricated. Changing a design after production has begun is costly, and may require reworking or scrapping existing boards. Therefore, planning your PCB function correctly is important to reduce cost and improve productivity.
The emergence of pcb hdi has made it possible to include high-density packages, such as small-pin and micro BGA, in consumer electronics devices. With the ability to accommodate more components on smaller PCBs, the use of HDI technology is growing in popularity as manufacturers strive to make their electronic devices more compact. This increase in device size requires an increased number of connections to support the functionality of the products.
To achieve these increases in connection density, designers must rely on advanced features such as blind and buried vias, and via-in-pad. Adding these advanced design techniques to a traditional PCB allows them to fit more technology in a smaller area, enabling new and innovative applications.
How Does PCB HDI Support the Integration of Advanced IC Packaging?
The most important factors in designing a successful high-density PCB are to determine the via, through-hole and microvia sizes needed, as well as the number of layers required for routing. You can do this by determining the interface + direction count for the largest IC on your board. Alternatively, you can use the ball pitch of your component to determine the via sizes you will need. The more layers you need, the higher your PCB price will be.
During the manufacturing process, your board manufacturer will use different types of stack-ups, constructions and layers. This will determine the overall density of your board. It is also important to know how to measure your board’s density, as there are many variables that affect this metric. For example, blind vias, skip vias, staggered and stacked vias all contribute to the overall board density.
The type of board you choose will also impact your budget. For example, a 2-n-2 high-density PCB is more expensive than a 1-n-1 high-density board. The amount of material used for the PCB will also affect the overall cost. This is why it’s important to find a reliable supplier with competitive pricing and a quick turnaround time.
The high-density design of your PCB will be more complex than a conventional PCB, and the details can quickly add up to a big bill. To lower your cost, choose a reliable supplier that offers a wide range of services including etching, imaging and laser drilling. In addition, you’ll want to make sure that your supplier uses semiconductor-class 100 clean rooms to prevent defects from improper handling. You’ll also want to keep your production volumes low, as large volumes can drive up costs.
