hdi pcb manufacturing process
01
Design and Layout: Using advanced blind via pcbB design software, we optimize routing and apply Laser Direct Imaging (LDI) to directly print circuit traces, improving accuracy and production efficiency.

02
Material Selection: We carefully choose low dielectric constant materials such as standard FR4 (IT-158, IT-180), high-performance FR4 (Isola 370HR, Ventec VT-47), eco-friendly FR4 (Shengyi S1000-2M, Kingboard KB-6160), or Rogers laminates (4350B, 4003C). Our large inventory of Rogers materials supports fast delivery for high-frequency and high-performance applications.

03

Laser Drilling: Precision laser drilling machines create microvias with diameters under 0.15 mm, aspect ratios of 1:1, and depths less than 0.25 mm—essential for HDI laser drilling pcb board designs requiring compact interconnections.

04

Sequential Lamination: Through advanced lamination technology, multiple layers are bonded with prepreg under controlled temperature and pressure, ensuring accurate layer-to-layer alignment in HDI printed circuit boards.

05

Plating and Etching: Copper is deposited on hole walls and circuit paths, followed by precise chemical etching to form clean and stable conductor patterns.

06

Surface Treatment: We apply finishes such as OSP, ENIG, or tin immersion to protect copper traces, enhance solderability, and guarantee long-term performance.

As a professional HDI PCB manufacturer in China, WeiYuanDa PCB follows a strict and advanced process to deliver reliable high-density interconnect PCB boards. Each step is carefully controlled to ensure precision, durability, and consistency for global OEMs.

ADVANTAGES OF HIGH-DENSITY INTERCONNECT HDI PCB

High Frequency PCB

High-frequency PCBs, typically operating from 500MHz up to 10GHz, are the foundation of next-generation technologies such as 5G communication, IoT devices, radar systems, and autonomous vehicles. Unlike standard boards, these high frequency printed circuit boards demand advanced materials with low dielectric constant (Dk) and low loss factor (Df) — such as rogers 4350b pcb and PTFE composites — to ensure signal integrity and minimal transmission loss.

As a specialized high frequency pcb manufacturer, WeiYuanDa stands out with in-house engineering, large-scale material stock, and strict RF testing capabilities. Whether you need high-quality PCB prototypes or mass production from a trusted 

microwave pcb manufacturer in China, we deliver precision manufacturing with fast lead times and competitive pricing.

MATERIALS USED IN HIGH-FREQUENCY PCBS

Choosing the right dielectric materials is critical in high-frequency PCB design, as they directly influence signal integrity, impedance control, and thermal reliability. Leading high-frequency PCB manufacturers select materials with a low loss tangent (Df), stable dielectric constant (Dk), and controlled thermal expansion to minimize signal degradation across RF, microwave, and millimeter-wave circuits.

At WeiYuanDa PCB, we work with a wide range of RF-certified laminates to ensure consistent performance from high-quality PCB prototypes to mass production. Below are four commonly used material families for high-frequency circuit boards.

Rogers Laminates

Rogers laminates such as RO4350B, RO3003, and RO3010 are industry benchmarks for advanced RF and microwave designs. They feature stable Dk values (3.0 to 10.2) with extremely low Df (down to 0.0013), enabling excellent signal integrity across broadband frequencies up to 77 GHz. These laminates are widely applied in antenna feed networks, phased array systems, 5G infrastructure, and power amplifiers — making them a preferred choice for high-frequency PCB manufacturers targeting performance-critical applications.

01

Taconic TLX and RF-35

Taconic materials, including TLX and RF-35, are known for their superior thermal stability and minimal moisture absorption. TLX laminates provide low insertion loss and excellent dimensional stability, ideal for multi-GHz RF switches, power amplifiers, and high-speed transmission lines. Meanwhile, RF-35 offers a cost-effective solution with reliable dielectric performance, compatible with standard PCB manufacturing processes. These characteristics make Taconic laminates versatile for both high-frequency circuit board prototyping and full-scale production.

02

Arlon 85N

Arlon 85N is engineered for demanding environments that require both electrical precision and mechanical strength. With a high glass transition temperature (Tg) of 250°C, thermal conductivity of 0.20 W/m·K, and robust peel strength, it ensures reliability in harsh conditions. This material is particularly suited for high-power radar transmitters, aerospace RF modules, and defense-grade systems. For high-frequency PCBs operating in extreme environments, Arlon 85N offers unmatched durability and performance.

Isola IS620 E-Fiberglass

For applications requiring a balance between cost and performance, Isola IS620 E-glass reinforced materials are an excellent option. They provide stable electrical properties up to 10 GHz, offering a practical mid-range alternative between standard FR4 and high-end PTFE systems. Ideal for consumer and telecom products operating under 5 GHz, Isola laminates allow high-frequency PCB factories to deliver cost-efficient yet reliable boards without compromising essential RF performance.
