Insulectro, a leading supplier of materials for use in the PCB and Printed Electronics industries, is distributing six new products that are virtually without competition in the PCB marketplace.


The products, which range from laminates to drill room materials, symbolize how PCB suppliers are keeping up with the OEM demands of thinner, faster, better.


“What we are seeing coming into the marketplace are materials that are focused on eliminating or reducing certain challenges fabricators have had to put up with, as well as new ones caused by rapidly evolving technology,” commented Insulectro Vice President of Technology Chris Hunrath. “It’s remarkable to have a portfolio of six performance products that are without peer in our industry.”


Vice President of Sales and Product Management Ken Parent agrees with Hunrath. “On one side of the perspective, we are offering Isola’s new laminate Chronon™ with its electrically transparent glass fiber reinforcement that eliminates differential pair skew issues for next generation High Speed Digital designs that operate about 10 GHz. On the other side, we’re introducing LCOA’s new conformal drill layer – Conformat™– that is soft enough to overcome image transfer challenges, yet hard enough to suppress exit side burrs in the drilling process,” Marsh stated. “Both products have been met with unprecedented enthusiasm.”


Hunrath added, “Plus, DuPont’s new Pyralux® HT is a laminate system with a service temperature of 225 degrees C. for flexible and rigid PCB applications. HT allows board shops to fabricate previously impossible designs for automotive, aerospace, oilfield, and other high temperature environments.


“Also taking the heat are two new products from Pacothane – ThermoPad™ and ThermoFilm™ – a press pad and film that utilizes a unique release technology for temperatures up to 300 degrees C. allowing reliable lamination and unmatched conformability of the latest generation of high temperature materials,” he concluded.


Other products include Ormet Sintering Paste which is a Z-axis interconnect paste that forms a metallurgical bond between layers and facilitates both rapid time to market and high complexity boards. Also, a polyimide silver paste is just about to come on the market.


 “Insulectro’s Six Pack Performance Products are very exciting for our customers. They will help shape our industry in the near future,” commented Parent. “OEMs will be delighted to see how these materials can deliver results not before imagined.”

Game Changers

Isola's Chronon™ & Tachyon 100G

Two new products that mix it up in High Speed Digital


Chronon™ laminate and prepreg products have been engineered to mitigate/eliminate skew issues in 40 Gb/s or more designs that require more bandwidth, such as backplanes and line cards.


Chronon materials deliver the necessary thermal robustness for lead-free applications and for electrical (low loss) applications that require tighter control of loss and skew.


In addition, it delivers the necessary thermal robustness for lead-free applications and electrical bandwidth (low loss) for applications that require more stringent signal integrity.


It also has PCB designer-friendly advantages because the Dk and Df ratings are close enough in value that they can be considered constant for all of the specified cores and prepregs.


Chronon is a proprietary high-performance, 192°C glass transition temperature (Tg) system for multilayer Printed Wiring Board (PWB) applications where maximum thermal performance and reliability are required. Chronon products use spread glass and reduced profile copper to mitigate skew in differential pair designs.


The use of ultra-smooth cooper is enabled by very high adhesive bond between the resin and the metal. Chronon has a nominal dielectric constant (Dk) of 3.68 and a very low nominal dissipation factor (Df) of 0.0040. Both are stable between -55°C and +125°C up to 40 GHz.


Chronon laminate materials are available in optimized laminate and prepreg forms in typical thicknesses and standard panel sizes to provide a complete material solution for high-speed digital multilayer backplanes and daughter cards.
