Current IssueInner Layer Precision & Yields
In this issue, we examine the critical nature of building precisions into your inner layers and assessing their pass/fail status as early as possible. Whether it’s using automation to cut down on handling issues, identifying defects earlier, or replacing an old line...
Engineering Economics
The real cost to manufacture a PCB encompasses everything that goes into making the product: the materials and other value-added supplies, machine and personnel costs, and most importantly, your quality. A hard look at real costs seems wholly appropriate.
Alternate Metallization Processes
Traditional electroless copper and electroless copper immersion gold have been primary PCB plating methods for decades. But alternative plating metals and processes have been introduced over the past few years as miniaturization and advanced packaging continue to develop.

Rogers Corporation to Highlight Next Generation Thin Materials for Millimeter Wave Multilayer Designs at Del Mar 2023
April 19, 2023 | Rogers CorporationEstimated reading time: 3 minutes
Rogers Corporation will exhibit at the Del Mar Electronics & Manufacturing Show April 26 and 27 at the Del Mar Fairgrounds in San Diego, CA (booth #622). High performance circuit materials used in multilayer structures which include a family of thin laminates and bonding materials are being highlighted along with Radix™ 3D Printable Dielectrics.
Highlighted Products:
Recently introduced Radix™ 3D Printable Dielectrics family of products, is the first available material featuring a dielectric constant of 2.8 and low loss characteristics at microwave frequencies. These printable dielectric materials give radio frequency (RF) designers unprecedented design freedom in creating new components, eliminating the need to consider typical manufacturing design constraints.
Radix3D Printable Dielectrics are proprietary composite materials designed for Digital Light Processing (DLP) 3D printing, enabling a scalable, high-resolution printing process for end-use RF dielectric component manufacturing. Rogers Corporation’s first Radix 3D Printable Dielectric material has a targeted dielectric constant of 2.8 and a dissipation factor of 0.0043 at 10 GHz when cured.
CLTE-MW™ laminates now include lower profile and thinner copper foil options to better serve the needs of designers and PCB fabricators producing millimeter wave PCB circuit designs. The new hyper very low profile (HVLP) ED copper cladding reduces insertion loss of transmission lines operating at 77 GHz by about 20% compared to standard ED copper foil. Additionally, the new HVLP copper cladding option is available in 9 µm, 18 µm and 35 µm thicknesses. These additional copper thickness options provide PCB fabricators more flexibility to achieve tight feature tolerances on signal layers, particularly with sequentially laminated designs.
These laminates are well suited for a range of applications including millimeter wave automotive and industrial radar antennas, 5G millimeter wave base stations and backhaul radios, and phased array radar systems.
SpeedWave® 300P Ultra-Low Loss Prepreg. With the increasing need for stackup flexibility in high layer count designs for 5G mmWave, high resolution 77 GHz automotive radar, aerospace & defense and high speed digital designs, SpeedWave 300P prepreg offers a broad range of competitively priced high performance options for the circuit designer. SpeedWave 300P prepreg can be used to bond a variety of Rogers’ materials including XtremeSpeed™ RO1200™, CLTE-MW™, and RO4000® series laminates.
This prepreg system offers a low dielectric constant of 3.0 – 3.3 and a low dissipation factor of 0.0019 – 0.0022 at 10 GHz with stable performance over a broad frequency range. This material is offered in multiple spread and open weave glass styles and resin content combinations to maximize stackup options.
RO4000® Products for Multilayer Structures:
Next generation products designed to meet the existing and emerging needs of advanced millimeter wave multilayer designs. RO4835T™ laminates, offered in a 2.5 mil, 3 mil and 4 mil core thickness, are 3.3 Dk, low loss, spread glass reinforced, ceramic filled thermoset materials designed for inner-layer use in multilayer board designs, and they complement RO4835™ laminates when thinner cores are needed.
RO4450T™ 3.2-3.3 Dk, low loss, spread glass reinforced, ceramic filled bonding materials were designed to complement RO4835T laminates and the existing RO4000 laminate family, and come in 2.5, 3, 3.5, 4, 4.5, 5 or 6 mil thicknesses.
RO4835T laminates and RO4450T bonding materials exhibit excellent Dk control for repeatable electrical performance, a low z-axis expansion for plated through-hole reliability, and are compatible with standard epoxy/glass (FR-4) processes. These materials are an excellent choice for multilayer designs requiring sequential laminations, as fully cured RO4000 products are capable of withstanding multiple lamination cycles. RO4835T laminates and RO4450T bondplys have the UL 94 V-0 flame retardant rating, and are compatible with lead-free processes.
RO3003G2™ high frequency laminates build on Rogers’ industry-leading RO3003™ platform to provide designers with improved insertion loss and reduced Dk variation. The combination of Rogers’ optimized resin and filler content along with the introduction of hyper very low-profile ED copper (HVLP) translates to Dk of 3.00 @ 10 GHz (clamped stripline method) and 3.07 @ 77 GHz (microstrip differential phase length method). RO3003G2 laminates also show very low insertion loss of 1.3dB/inch for 5 mil laminates as measured by the microstrip differential phase length method.

Designers Notebook: Impact of Advanced Semiconductor Packaging on PCB Stackup
01/07/2025 | Vern Solberg -- Column: Designer's NotebookTo accommodate new generations of high I/O semiconductor packaging, printed circuit board fabrication technology has had to undergo significant changes in both the process methods and the criteria for base material selection and construction sequence (stackup). Many of the new high-function multi-core semiconductor package families require more terminals than their predecessors, requiring a significantly narrower terminal pitch. Interconnecting these very fine-pitch, high I/O semiconductors to the PCB is made possible by an intermediate element referred to as an interposer.

At this point, we have a functioning board, but we still need to protect the PCB from environmental effects and document the circuit components. This brings us to the solder mask and legend phase of production.
Global PCB Connections: Following DFM Rules Leads to Better Boards
12/18/2024 | Jerome Larez -- Column: Global PCB ConnectionsAs a PCB field applications engineer, ensuring smooth communication between PCB designers and fabricators is one of my frequent challenges. A critical part of that dialogue is design for manufacturing (DFM). Many designers, even experienced ones, often misunderstand or overlook important DFM considerations. They may confuse design rules with manufacturing minimums, leading to technically feasible designs that are difficult or costly to produce. In this column, I will clarify some common DFM guidelines and help designers understand the difference between “design rules” and “minimums” while sharing best practices that will simplify the production process and ensure the highest quality PCB.
