How China HDI PCB Manufacturer In Shenzhen Design HDI PCB (2020 Guide)?

How HDI Technology is Beneficial for Modern-Day Technology?

With the starting of the 21st century the technology race had started.

With every passing day, HDI PCB became more and more elegant and advanced.

Hence, today we are standing in a world which totally depends on this technology.

Everything, whether it belongs to kitchens or offices, we depend on this modern technology.

Furthermore, the development of this technology totally relies on PCBs.

The industry of PCB has made changes because of the advancements in modern electronics.

So, all these requirements led the manufacturers to design HDI PCBs.

When manufacturing high density interconnect (HDI) MPPs, a number of functional features are taken into account:

  • The track density is increased by reducing the overall width of the conductors and the gaps between them;
  • A variety of layered multilevel vias are applied, including blind and blind holes;
  • Dielectrics of the ultrafine type RCC are used.

Drivers for the HDI Board Industry

Among the main factors is the need to simultaneously increase the number of leads of complex components, interlayer connections and reduce the total dielectric area.

Reducing the number of output components, as well as body miniaturization are other factors influencing the relevance of the development of HDI technology.

Application area

  • Highly sophisticated mobile devices
  • Special military systems
  • Compact surveillance/tracking systems
  • Highly sophisticated multimedia devices
  • Portable Medical Sensors and Detectors

Design capabilities

High-density PPMs consist of a certain number of sequentially alternating conductive patterns and dielectric layers.

The main difference between HDI and conventional multilayer PCBs is the use of ultra-thin foil and foil material with a small dielectric thickness.

The average width of the conductors in the plate is 0.1 mm.

As a result, it is possible to produce various elements of high-resolution topology.

In some MPP models, dielectric materials based on unreinforced (fiberglass) epoxy resins are used in the manufacture. Such PCBs are called RCC (Resin Coated Copper Foil).

Materials

When creating a high-density MPP, depending on the required technical characteristics and operating nuances, glass fiber laminate is used:

  • FR4 140 ˚glass transition temperature –  foil thickness 18-140 microns.
  • FR4 170 ˚glass transition temperature –, whose foil thickness is 18-105 microns.
  • FR4 Halogen Free –  with 35-micron foil, etc.

Features of HDI Production Technology

HDI boards are often made by layer-by-layer growth and/or pairwise pressing.

What is the reason for this? This is due to the fact that there is a need to create two different types of vias in the board structure:

  • Buried– between the inner and outer layers (Buried);
  • Blind– between the inner layers (Blind).

In terms of production equipment, modern high-density MPCs are created using lasers.

At the same time, laser drilling of the outer, inner layers contributes to the formation of blind laser micro-holes, which are sequentially covered with the following layers and turn into blind holes. If paired pressing occurs, holes are drilled and plated.

The use of combined and subtractive methods became possible after the development of technologies for the production of thin foil.

As a result, lining dielectrics with thin foil (5-12 microns) has significantly reduced prices for HDI boards.

Basically, HDI PCBs are a highly advanced form of this industry.

And, China HDI PCB manufacturers in Shenzhen are essential for sleek and stylish electronic designs.

And they are creating these high-tech products for all the modern technology needs.

You can easily solve your professional problems anywhere and anytime using these latest.

It does not matter where you are in the office or home you have always connected to your official meeting.

You can handle your business dealings even during the flight. All these modern electronic developments have become possible because of the HDI PCBs.

Hence, HDI technology is core and very advantageous for modern electronic devices.

What is HDI PCB?

HDI PCB boards are today’s rapidly growing technologies in the PCB industry.

Actually, HDI PCBs are higher circuitry density circuit boards in comparison to traditional PCBs.

HDI stands for High-Density Interconnect. They are PCBs with an extra number of interconnections.

But they occupy minimal space.

As a result, it causes miniaturization of the circuit boards.

In China HDI PCB manufacturer in Shenzhen place all the components extremely close, it remarkably reduces the space.

But it does not affect the functionality of HDI PCBs.

Moreover, when we describe more clearly about HDI PCBs, then actually it is a PCB which have an average of 120 to 160 pins per square inch.

The design of HDI in fact integrates versatile routing and placement of dense components.

In an HDI design, manufacturers reduce the copper drill.

Dancer circuitry has actually developed with the implementation of,

Additionally, this latest technology of HDI has made popular the technology of Microvia.

All and all, the HDI technology in PCBs actually have,

  • Minor vias
  • Lines
  • Capture pads
  • Density of higher connection pad.

This technology is extremely beneficial to maximize the performance of electrical appliances.

Moreover, it is also really helpful in order to reduce the size and weight of electronic devices.

Hence, HDI PCBs are an ideal choice for costly laminated boards and high-layer count.

Building Purposes of These Innovative and Non-Conventional HDI Boards?

China HDI PCB manufacturers in Shenzhen are producing high-tech PCBs for the latest and sleek design devices.

Additionally, for the perfect manufacturing of HDI PCBs manufacturers actually needs highly exceptional procedures and equipment like,

  • Laser direct imaging
  • Sequential lamination cycles.

Additionally, HDI PCB boards consist,

  • Tighter spacing
  • Thinner lines
  • Tighter annular ring.

This high technology PCBs also use materials with the extra slim specialty.

PCB manufacturers need serious investment and additional time in manufacturing equipment and processes for the effective, successful production of HDI boards.

Why HDI PCB Have Been Developed?

PCB manufacturers had first developed for the purpose order to provide high performance and computational power in just a small envelope.

Manufacturers actually wanted to provide powerful telecommunications to their customers.

Moreover, they also desired to discover extra complex electronic circuitry in the much smaller and denser package.

So, PCB manufacturers developed these HD PCBs to meet all the above needs and demands.

In fact, China HDI PCB manufacturers in Shenzhen are also producing this most wanted latest technology of HDI PCBs.

But another important key driver in the evolution of HDI PCB was trended in the technology of integrated circuits (IC).

Basically, this resin-coated copper had actually developed particularly in order to,

  • Longer drill times
  • Assistant with poor hole quality
  • Allow for thinner PCBs.

In fact, resin-coated copper also has the ability to ultra-thin copper foil and has an ultra-low profile.

This is an ideal material that has chemically primed and treated for the finest and thinnest line and spacing technology.

Implementation of dry resist to laminate yet makes use of heated roll method to apply the resist to the basic material.

However, this has known as an old technology process.

But manufacturers still recommend preheating the material to a desirable temperature before the lamination process for creating HDI boards.
