Top 8 HDI PCB Manufacturers in the World

High-Density Interconnect Printed Circuit Board (HDI PCB) refers to the type of circuit board that offers improved properties than the conventional boards do. With the introduction of the HDI technology into consumer electronics optimization, these devices now have improved spacing.

One of the advantages to using a HDI PCB is the higher wiring density. Besides, one can leverage the circuit board to incorporate or add more components into the Printed Circuit Board (PCB).

Today, there are hundreds of HDI PCB manufacturers offering this type of circuit board design in different parts of the world. We have curated a list of the top eight (8) HDI PCB manufacturers, as well as pointed out the reasons why they are different from the other manufacturers.

1. Rayming PCB & Assembly

Also known as Rayming Technology or RayPCB, this is one of the HDI PCB manufacturers you can trust. Located in Shenzhen, China, we offer a wide range of HDI PCB services.

One core area we focus on is the stackup, which plays an important role in how the circuit board is optimized to function. For emphasis, RayPCB uses the following HDI PCB stackup or structure:

1+N+1, 2+N+2, 3+N+3, 4+N+4 and any layer in R&D.

Here is a breakdown of the RayPCB HDI PCB stackup:

  • 1+N+1: this means that the Printed Circuit Board (PCB) we fabricate will have only one build-up of the High-Density Interconnect (HDI) layers.
  • 2+2+2: just like the above, this refers to the number of build-ups of the HDI layers the PCB has. In this case, it is two (2).
  • 3+N+3: this type of HDI PCB has three build-ups of the HDI layers.
  • Any Layer HDI PCB: this refers to the HDI PCB that has all the layers of the Printed Circuit Board (PCB0 as High-Density Interconnect (HDI) layers. We use this HDI PCB stackup because it allows for the flexible interconnection of the conductors on any layer of the PCB. The interconnection is made with the any layer via – the copper-filled or populated stacked microvia structures.

RayPCB’s HDI PCB Capabilities

The following are some of the reasons why HDI PCB consumers prefer having RayPCB to handle the fabrication:

  • Multiple HDI PCB Design Technologies: there are different design processes used when fabricating the HDI PCB. RayPCB maximizes as many of these as possible. For example, we are experts at using the following HDI PCB technologies: tiny circuit, microvia manufacturing, and the through-hole metallization processes.
  • Specialized Fabrication Typologies: different types of HDI PCBs exist. RayPCB helps you to fabricate these circuit boards, as per the target applications. The following are some of the HDI PCB types we fabricate: Multilayer HDI PCB, Flexible HDI PCB, Rigid-Flexible HDI PCB, and Rigid HDI PCB.
  • Several Material Options: we also use different kinds of materials when manufacturing the HDI PCB. The following are some of the supported materials: First Generation Microvias, High-Temperature FR4, and Halogen-free materials.

2. PCBcart

PCBcart is a full-service PCB fabrication and assembly service provider in China. The company believes that PCB consumers, including those ordering for the HDI PCB, should get value for their investments.

That informs the reason behind the manufacturer’s dedication to making in-house checks, raising the standards of the HDI PCB, while offering an excellent customer service.

HDI PCB Capabilities

We were able to verify that PCBcart specializes in offering the following HDI PCB services:

  • Competitive Pricing: besides the improved design of the HDI PCB, the manufacturer also pays attention to the market yearnings. PCBcart understands that not all consumers may afford to make bulk purchases of the circuit board, hence, the decision to wave the Minimum Order Quantity (MOQ). Interestingly, you get to enjoy competitive pricing no matter how many HDI PCBs you are ordering for.
  • Multi-Layer Capabilities: PCBcart promises to fabricate different layers of the HDI PCB, up to 24 layers. These fabrications are done in addition to offering the HDI PCB in different structures.
  • HDI PCB Fabrication Process: the manufacturer deploys different HDI PCB techniques. These include the popular via in pad, flex-rigid combination and the buried capacitor. The buried capacitor technique is exclusively used for the prototypes of HDI PCBs measuring less than 1 meter square.
  • Materials Used: PCBcart uses different kinds of materials, such as the FR4 and Rogers lamination combination, FR4 standard Tg 140˚C, and the FR4 High Tg 170˚C.
  • HDI PCB Surface Finishes: the following are examples of the surface finishes used by PCBcart: Organic Solderability Preservatives (OSP), Immersion Silver, Lead Free HASL, Immersion Tin, Hot Air Solder Leveling (HASL), and the Electroless Nickel/Immersion Gold (ENIG). A majority of these surface finishes are RoHS-compliant.
  • Production Capabilities: PCBcart has a variety of HDI PCB production capabilities. For example, the company has a flexible build time of 2 days and 5 weeks maximum. It also engages in HDI PCB prototyping, mass production and small-middle batch production of the HDI PCBs using the blind vias, blind/buried stacked vias and the blind/buried staggered vias micro vias typologies.
