Rogers Corporation will exhibit at DesignCon in Santa Clara, Calif. (booth #609) highlighting some of its high performance circuit materials.

DesignCon is a premiere event for electronic design engineers working on circuit and system levels held at the Santa Clara Convention Center, January 31 – February 1.  

Some of the products being featured:

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.

Radix 3D Printable Dielectrics are proprietary composite materials designed for digital light Processing 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.

Rogers Kappa® 438 laminates are now available in 10 mil. Designed using a glass reinforced hydrocarbon ceramic system that offers superior high frequency performance and low-cost circuit fabrication results in a low loss material which can be fabricated using standard epoxy/glass (FR-4) processes. Kappa 438 laminates also have the UL 94 V-0 flame retardant rating and are lead free solder process compatible. Standard thicknesses include 10, 20, 30, 40, and 60 mil. 

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.

COOLSPAN Thermally & Electrically Conductive Adhesive (TECA) is a thermosetting, epoxy based, silver filled adhesive film used in bonding high power circuit boards and has a storage life of up to 12 months from date of manufacture. COOLSPAN films provide a convenient and reliable approach to bond high power circuit boards, heavy metal back-planes, heat sink coins, and RF module housings. This approach overcomes voiding and flow issues that are problematic for sweat soldering and dispensed adhesive approaches. COOLSPAN TECA films can be tack soldered in a fixture, ensuring accurate registration. This is followed by a tooled thermal cure or PCB press cycle.

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.

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.
