HDI PCB Basics

What Is High Density Interconnect

When you look for advanced printed circuit boards, you might hear about high density interconnect. HDI lets you put more connections in a small area. HDI PCB technology uses things like microvias, blind vias, and buried vias. Microvias are very small holes made with lasers. They connect different layers inside the board. These features help you fit more parts and lines on your PCB. You can find HDI PCB types in smartphones, tablets, and medical devices.

Designers use HDI to make boards with very thin lines and spaces. Some lines and spaces are as tiny as 50 microns. HDI gives better signal quality and less electrical noise. HDI PCB types often use strong materials like FR4 or Rogers. The number of layers can be from 4 to 30. The copper can be as thin as 18μm. Here is a quick look at some main features:

Why Manufacturer Choice Matters

Picking the right HDI PCB manufacturer is important for your circuit. A good manufacturer uses the best technology and follows strict rules. If you choose the wrong one, your boards might have problems. You could get signal loss or your device might not work. Good manufacturers meet standards like ISO 9001 and UL. They also give strong customer support and fast delivery.

Many industries need high density interconnect PCBs. Medical devices need them for accuracy and safety. Cars use HDI for smart driver systems. Telecom companies need fast and steady signals. When you pick a trusted HDI PCB supplier, your project has a better chance to succeed.

Define HDI PCB Requirements

Technical Specs

First, write down what your HDI PCB needs. The right specs help your board work well. HDI PCBs use special ways to make them, like laser drilling and sequential lamination. These ways help make smaller vias and tighter wiring. Microvias and blind vias are important in HDI PCB design. They help you build small circuits that keep signals strong.

Industry rules give clear goals for HDI PCB design. For example, lines and spaces can be as tiny as 100 microns. Microvias are usually 100 to 150 microns wide. You should also check the number of layers, which is often 4 to 16. Materials like FR-4 or polyimide help with heat and signal quality. Impedance control is needed for fast signals. You also need to handle heat with thermal vias and good plating.

Tip: Always make sure your design specs follow industry rules. This helps your board work well and last longer.

Application & Quantity

You need to say how you will use your HDI PCB and how many you want. What you use it for changes the design, materials, and how it works. For example, medical devices need to be very accurate and steady. Cars need strong materials and safe connections. Electronics for people often need thin boards with lots of layers.

How many boards you need is also important. Small orders may need more design choices. Big orders care more about price and making them fast. Tell your supplier what you need and how many early. This helps them pick the best materials, stack-up, and design for your job.
