High-Density Interconnect HDI PCB Board
HDI Printed Circuit Boards
High-Density Interconnects (HDI) process technology has continually evolved into China PCB designs since its initial introduction in semiconductor package modules in the late 1980s. Today, drilling laser control depth blind µVias into a variety of laminates, utilizing a variety of copper plating processes, has become the dominant method of HDI fabrication. Topscom's extensive qualification methodology assures the reliability of complex µVia structures in a range of laminates that are thermally robust to multiple PCB SMT assembly reflow cycles. Our Material and HDI development roadmaps are focused on continuous feature size reduction for µVias, which is essential for today's cost-sensitive China PCB design.

Topscom has been a leader in HDI interconnect innovation and mass production for over fifteen years. All of our factories have mass production capacity for µVia-based HDI processing, combined with fine line copper trace formation by semi-additive or subtractive copper plating.

Topscom is one of the first companies to provide volume HDI capability to our global customers. Our continuous investment in developing processes for world-class fine-line µVia technology helps us maintain our position as a leader in sophisticated HDI China PCB manufacturer. We provide complete solutions to our customers by early China PCB design reviews to help eliminate potential cost or yield challenges, shortening NPI and production cycle times, and delivering reliable, high-quality products in the most cost-effective ways.

Every Layer InterConnect ELIC PCB Board
For more than a decade, Topscom has continuously innovated next-generation µVia technologies. As the conventional laser via plating technology reached its limits, the Every Layer Interconnect (ELIC) process flow was developed in Topscom China and Germany R&D Labs. Also know as, Any Layer Technology, Topscom's ELIC process was launched into production in 2006. Innovations in laser µVia drilling, copper plating, direct imaging of resists and masks, and improved registration techniques have helped continually refined Topscom's state-of-the-art mass production facility in Zhuhai, China.

Thermal Management
Thermal challenges are growing concerns with today's designs. From component density issues, reduced thermal paths, and increase power amplification, these present challenges to help dissipate heat within the design of the PCB China. To help minimize these issues, Topscom provides a broad suite of innovative thermal management solutions.

Through the use of embedded heat transfer techniques, Topscom can offer processes for solid-plated µVia arrays, embedded metal structures ("Coins"), both flush mounted or cavity recessed, and surface-attached heat transfer media. These technologies offer a wide range of thermal dissipation within the PCB, and Topscom engineering has industry-leading expertise in thermal solutions.

Thru-Hole Via Farm
Utilizing dense via formations can help improve thermal dissipation from the component side to the backside of the PCB. Topscom can provide increased redundant via structures in both thru-hole, and µVia deigns.

For enhanced heat dissipation in power amplifier boards, network products customers are designing with “COINS” technologies into high ASP 10-16 layer count PCBs. Three different copper COINS technologies have been setup in Topscom China.

In response to new system performance demands in the wireless infrastructure market, Topscom introduced our first inlay Printed Circuit Board (PCB) technology in 2013. In prior product applications, a full panel FR4 material is applied in hybrid stack-up construction with an entire panel core of expensive high frequency yet low loss material, resulting in an expensive finished product.

To reduce total panel cost, Topscom introduced selective semi-finished inlay circuitry using high-frequency laminate, into the overall FR4 laminate panels using 3D structuring. With only a small part of the final China PCB design area specified for high-frequency signal transfer, our inlay innovations reduce the amount of high-frequency laminate and allow integration of our thermal solutions into your final optimized design. A full design guide is available upon request.
