HDI PCB
HDI PCB (High-density interconnect printed circuit board)is a fast growing part of the PCB industry, nowadays our devices are getting more and more portable, at the same time components inside are getting smaller and more lightweight, but providing better performance, all these requirements are needed to be functional into a smaller area, this is just what an HDI PCB can offer.
Your Leading HDI PCB Supplier in China
In the past, computers used to fill up an entire room, but now, with HDI technology, You can find HDI boards in laptops, cellphones, and watches, as well as other portable consumer electronics such as digital cameras and GPS devices.
HDI PCBs had played an important role in providing us with a more efficient life.
Your Valuable HDI PCB Manufacturer And Supplier
HDI PCBs have higher circuitry density per unit than traditional PCBs. HDI PCB uses a combination of buried vias and blind vias, as well as micro vias, with our state-of-the-art laser drilling machine( Mitsubishi), laser direct imaging ( LDI), we are able to provide you fast delivery services for HDI PCB prototypes.
It covers both basic and advanced aspects about HDI printed circuit boards, from definition, design, benefits, design, applications, and many more.
By the end of this guide, you’ll be an expert in the HDI PCBs.
Why Choose Venture HDI PCB

Microvias achieved High-Density Interconnection What is Microvia?
A Blind structure with a maximum aspect ratio of 1:1, terminating on a target land with a total depth of no more than 0.25mm measured from the structure’s capture land foil to the target land named Microvia .
The Role of Microvias
●Space saving on PCB
●Faster signal transfer
●Low resistance and capacitance
●Reduced weight of final PCB
Mircovias Types we can support
●Blind Microvias
●Buried Microvias
●Stacked Microvias
Tree Types Of HDI PCB structures
In IPC-2226, the structure of HDI is defined by type, and there are three types, as following
●Type 1 :It for Single layer,the Mircrovias in one side or both sides of the core.it used Microvias and the PTH Hole for interconnection.This structure only uses for blind holes .
●Type 2:Same as Type 1 ,Microvias local in one or both sides ,but for interconnection It uses blind holes and buried holes.
●Type 3 :This type with high demanding for factoriers ,because it the most complex .there are contain at least two layers of microvia on one or both sides of the core .it uses blind holes, buried vias, through holes.
Venture can provide professional technology and large-scale HDI PCB products.
HDI PCB Material Requirements
There are three typical material for HDI PCS is Resin-coated-copper(RCC),cost Polyimide film, Polyimide Metallized film and Pure polyimide film.
The Features of HDI material include:
●Small thickness,
●Light weight,
●Flexibility
●Reduced flammability
With the development of HDI technology, HDI PCB materials have to meet more requirements. Venture can provide HDI PCB materials with high heat resistance, good flatness, high dielectric constant, low dielectric loss, low coefficient of thermal expansion, high welding stability.
