DuPont Launches Pyralux Flexible Circuit Material For FPC & Rigid Flex PCB Products

- Jun 12, 2019-

DuPont's competence in polymer chemistry has actually made its line of Pyralux laminates the industry leader in flexible circuit products for over 30 years. Today, Pyralux flaunts a diverse portfolio made to satisfy the numerous flexible circuit demands of customers in the telecommunications, defense, auto, aerospace, as well as clinical sectors. This year, DuPont remains to expand this profile by launching Pyralux AG-- a brand-new copper-clad laminate that will certainly allow producers to effortlessly transition from models to high volume production.


Pyralux AG is DuPont's initial copper-clad laminate to be used in both sheets as well as rolls with global schedule. This means that a maker will have the ability to construct a prototype in one region and also transfer to commercial manufacturing in an additional area without having to alter products, conserving time and money on requalification. Given that its launch, Pyralux AG has actually already been qualified in many applications in consumer electronics, consisting of sensing units, audio speakers, batteries, as well as cameras for smart devices. Past customer electronic devices, Pyralux AG is likewise ideal for sure clinical and also automotive applications


Pyralux AG is an all-polyimide, double-sided copper-clad laminate that is IPC 4204/11 certified as well as UL 94 V-0 ranked. Typical values for loss tangent and also dielectric consistent are 0.007 and 3.2, specifically, and dimensional stability is within ± 0.07%. It is a drop-in service that is fully suitable with all conventional adaptable circuit construction procedures, including oxide treatment as well as wet-chemical, plated-through-hole desmearing. It is provided with electrodeposited as well as rolled stiff copper in balanced building and constructions that can range in thickness from 7 μm to 35 μm (1 oz/ft2). The dielectric densities vary from half to two mils. The conventional size of a sheet is 18 in. by 24 in. (TD x MD) and a standard roll is 19.7 in. (500 mm) by 328 ft (100 m).

  • Pyralux AG is simply the current addition to DuPont's wide profile of laminates.


  • Pyralux AP is the sector standard in terms of electrical as well as mechanical efficiency and also has held up against the most requiring applications for over three decades; today, it is playing an essential function in the appearance of 5G in advanced telecommunications, military, and aerospace applications, especially in the Rigid Flexible PCB applications.


  • Pyralux LF is a trustworthy, acrylic-based product that is supplied as a copper-clad laminate, coverlay, bondply, and also sheet adhesive


  • For applications needing a UL score, Pyralux FR is a flame-retardant, acrylic-based product that is supplied as a copper-clad laminate, coverlay, bondply, and sheet adhesive

  • Pyralux TK is a fluoropolymer/polyimide compound, double-sided copper-clad laminate that displays the lowest loss features on the marketplace

  • Pyralux HT is a bonding movie with the highest service temperature offered and also low-loss performance when paired with Pyralux AP in high-frequency applications


Beyond Pyralux AG, DuPont has a variety of products that play a crucial function in consumer electronic devices.


  • Pyralux TAH and TAHS are all-polyimide, double- as well as single-sided copper-clad laminates that recently were qualified by a major OEM for their high-frequency antenna application

  • Pyralux HXC is a black coverlay that is the market leader in applications where an attire, matte black appearance is called for

  • Pyralux AC is a single-sided, all-polyimide copper-clad laminate that is excellent for applications calling for thin, light, as well as high-density circuitry together with chip-on-flex accessory


Past the Pyralux product line, DuPont uses Interra, a line of embedded capacitance laminates for rigid printed circuit board, and also Temprion, a line of thermal administration products. Interra slim copper-clad laminates are replacing surface-mount chip capacitors in rigid boards, and inevitably enhancing reliability, reducing expenses, simplifying layouts, as well as decreasing packaging dimensions. Temprion products are films as well as laminates with high thermal conductivities that can dissipate warmth in the toughest problems seen in automobile, protection, and aerospace applications.
