(25. 8. 2017) New laminates Kappa™ 438 and CLTE-MW™ from ROGERS (Nové plátované materiály od ROGERS)

Kappa™ 438 lamináty

Byly vyvinuty pro návrháře PCBs jako lepší a spolehlivější alternativa FR-4 materiálů. Jedná se o sklem vyztužené uhlovodíkové keramické materiály nabízející vynikající vysokofrekvenční vlastnosti a nízkonákladovou výrobu obvodů, které mohou být vyrobeny použitím standartního procesu epoxid / sklo (proces jako u FR-4).

Kappa lamináty překonávají výkonostní omezení FR-4 materiálu a poskytují optimální kombinaci ceny, výkonnosti a životnosti. Jedná se o nízkoztrátové materiály, s vynikající tolerancí dielektrické konstanty, těsnou kontrolou (tolerancí) tlouštky a jsou zkonstruovány pro vynikající a opakovatelnou výkonnost.

CLTE-MW™ lamináty

Keramicky plněné, sklem vyztužené PTFE kompozity. Vyvinuty za cílem poskytnout cenově efektivní, ale též vysoce výkonné řešení pro návrháře PCBs. Tento plátovaný materiál je vhodný pro aplikace, kde dominantní roli hraje omezení tloušťky v důsledku fyzických nebo elektrických omezení. Sedm dostupných tlouštěk v rozmezí 3 mils až 10 mils zajistí ideální rozestup signál – zem pro dnešní technologie 5G, či další návrhy z oblasti milimetrových vln. CLTE-MW laminát je též k dispozici v několika variantách měděných fólií.

CLTE-MW lamináty jsou vyztužené rozptýleným sklem, které spolu s vysokým plněním pomáhají minimalizovat vysokofrekvenční účinky vazby skla na šíření elektromagnetických vln. Vyztužení skleněným vláknem též poskytuje vynikající rozměrovou stabilitu.

Kappa™ 438 Laminates

Kappa 438 thermoset laminates were developed for wireless circuit designers looking for a better performing and more reliable alternative to FR-4 laminates. These laminates were designed using a glass reinforced hydrocarbon ceramic system that offers superior high frequency performance and low cost circuit fabrication resulting in a low loss material which can be fabricated using standard epoxy/glass (FR-4) processes.

Wireless circuit designers can now enjoy a true breakthrough with Kappa 438 laminates because they feature the performance of mid-tier circuit materials that exceed performance limitations of FR-4, and provide the optimum blend of price, performance and durability. Kappa 438 Laminates have low loss, excellent dielectric constant (Dk) tolerance, and tight thickness control and are engineered for outstanding, repeatable wireless performance. Kappa 438 laminates have a low Z axis CTE and High Tg for improved design flexibility, PTH reliability, and automated assembly compatibility, and can be fabricated using standard epoxy/glass (FR-4) processes. These laminates are compatible with conventional bondplies and lead free solder processes, and have the UL 94 V-0 flame retardant rating. A design Dk of 4.38 tailored to FR-4 industry standard norms facilitates ease of converting existing FR-4 designs where better electrical performance is needed.

CLTE-MW™ Laminates

CLTE-MW™ laminates are ceramic filled, woven glass reinforced PTFE composites. CLTE-MW laminates were developed to provide a cost effective, high performance material for the circuit designer. This unique laminate system is well suited for applications that have limitations in thickness due to either physical or electrical constraints. The seven available thickness options from 3 mils to 10 mils ensure that ideal signal to ground spacing exists for today’s 5G and other millimeter wave designs. In addition, a variety of copper foil options are available including rolled, reverse treated ED, and standard ED. Resistive foil and metal plate options are also available upon request.

The CLTE-MW laminates are reinforced with spread glass, which along with a high filler loading help minimize the high frequency glass weave effects on electromagnetic wave propagation. The woven glass reinforcement also provides excellent dimensional stability. Other key features of the laminate include low z-axis CTE (30ppm/°C) for excellent plated through hole reliability, a low loss tangent of 0.0015 at 10 GHz to enable low loss designs, and low moisture absorption of 0.03% to ensure stable performance in a range of operating environments. Thermal conductivity of 0.42 W/(m.K) enables heat dissipation in aggressive designs along with a high dielectric strength of 630 V/mil to ensure good z-axis insulation between conductor layers. The UL94 V-0 flammability rating enables the use of CLTE-MW laminates in commercial applications.

CLTE-MW laminates are well suited for a range of applications including Amplifiers, Antennas, Baluns, Couplers and Filters. Applicable markets range from Commercial and Consumer to Defense and Aerospace.
