The Registration Sweet Spot
Registration is underrated and underappreciated. The key is to ensure proper registration from layer to layer across the entire printed circuit board. It’s a holistic process requiring anticipation, prediction, precise attention at each step, and detailed data tracking and monitoring.

Ventec Launches Dk 3.48 Ceramic-Filled Hydrocarbon Thermoset MaterialMay 15, 2018 | Ventec International Group Co., Ltd.
Estimated reading time: 1 minute
Ventec International Group Co., Ltd. has added to its extensive signal integrity laminate and prepreg range with the launch of tec-speed 20.0, a ceramic-filled hydrocarbon thermoset material designed for high frequency applications. tec-speed 20.0 combines unrivalled high-frequency performance (Dk 3.48 / Df 0.0037), superior loss characteristics and the highest reliability with fast availability and efficient delivery through Ventec’s fully controlled and managed global supply chain and technical support-network.
No More Compromises - Performance, Price and Availability
The tec-speed 20.0 (VT-870) is designed for the world's most demanding high frequency Printed Circuit Board applications such as cellular base station antennas, power amplifiers, LNB for broadcast satellites, automotive radar and RFID. With tec-speed 20.0, Ventec has responded to customer demands for a high-performance, reliable and cost-efficient high frequency material that also has a fast and efficient global delivery promise and dependable technical support.
The tec-speed 20.0 is a high-frequency laminate designed to preserve signal integrity up to high-GHz frequencies and has extremely low 3.48 dielectric constant (Dk) and 0.0037 dissipation factor (Df). By minimizing insertion losses, tec-speed 20.0 provides greater freedom to optimize copper trace widths, spacing, and PCB thickness.
Tested according to IPC-TM-650 specifications, the industry’s gold standard, tec-speed 20.0 is UL approved, reliable and durable, offering outstanding thermal performance. High glass transition temperature (Tg), high peel strength, and low CTE ensure structural integrity and reliability, in process and hardworking applications.
Now, tec-speed 20.0 is available as laminate or prepreg (VT-870PP), as standard with HTE copper foil or with HVLP (Hyper Very Low Profile) foil to attenuate passive intermodulation (PIM) effects.
The tec-speed 20.0 ceramic-filled hydrocarbon thermoset material is manufactured by Ventec using strict quality-controlled processes that are certified to AS9100 Revision D, ISO/TS16949 and ISO 9001:2015, and, like all Ventec products, is backed by a fully controlled and managed global supply chain, sales- and support-network.

The "Global Copper Clad Laminates Market (by Type, Application, Reinforcement Material, & Region): Insights and Forecast with Potential Impact of COVID-19 (2023-2028)" report has been added to ResearchAndMarkets.com's offering.
The SCHMID Group, a global solution provider for the high-tech electronics, photovoltaics, glass and energy systems industries, will be exhibiting at productronica in Munich from November 14 – 17, 2023.
The topic of intrinsic copper structure has been largely neglected in discussions regarding the PCB fabrication quality control process. At face value, this seems especially strange considering that copper has been the primary conductor in all wiring boards and substrates since they were first invented. IPC and other standards almost exclusively address copper thickness with some mild attention being paid to surface structure for signal loss-mitigation/coarse properties.
At PCB West, I sat down for an interview with John Andresakis, the director of business development for Quantic Ohmega. I asked John to update us on the company’s newest materials, trends in advanced materials, and the integration of Ticer Technologies, which Quantic acquired in 2021. As John explains, much of the excitement in materials focuses on laminates with lower and lower dielectric constants.
Printed circuit board (PCB) reliability testing is generally performed by exposing the board to various mechanical, electrical, and/or thermal stimuli delineated by IPC standards, and then evaluating any resulting failure modes. Thermal shock testing is one type of reliability test that involves repeatedly exposing the PCB test board to a 288°C pot of molten solder for a specific time (typically 10 seconds) and measuring the number of cycles it takes for a board’s copper layer to separate from the organic dielectric layer. If there is no delamination, fabricators can rest assured that the board will perform within expected temperature tolerances in the real world.
