    I received some of the board material in question, and while it is
    interesting it doesn't seem useful for anything I am building at the

    Like you, my immediate thoughts are that it might be work for
    mounting LEDs on a pre-stressed, curved surface, or the narrower
    strips might serve for 'whiskers' on a robot of some sort.

    But the stuff *is* really expensive, especially the narrow strips.

    I have bought a good bit of 0.014 in double sided 1 oz copper FR4
    board from 'abcfab' on eBay. The descriptions are a bit sketchy but
    the product seems quite good and arrives reasonably quickly. I have
    also purchased 0.030 in. and 0.060 in. board stock, as well as some
    unlaminated 0.014 in. base material for experiments.

    This source sells a variety of stock from 0.014 in. to 0.125 in. and
    Cu copper weights up to 5 and 6 oz/in (sq).

    I have also purchased unlaminated Kapton Polyimide in a variety of
    thicknesses from 'PaperStreetPlastics'. I have been quite satisfied
    by the quality and service from this source as well. I have used this
    stuff for experimentation with flexible circuits using conductive
    paints and/or inks. I've tried silver, cu, and carbon, so far.
    Polyimide's's main claim to fame is that it is flexible and can
    withstand solder temperatures.his material requires high resistance against repeated bending and suitability for the compact, high parts mounting density PCBs in small electronic devices, such as cellular phones, digital cameras, and notebook PCs. This material enables high density and 3D interconnection by laminating thin films that have superior resistance against heat, chemicals and flexural stress on copper clad.

    Rigid-flex circuit boards are those consisting of a combination of flexible and rigid circuit board areas and are always processed in a single delivery panel.

    The rigid circuit board areas serve as the solid base to which components, control elements and connectors are added; they are joined together by the continous flexible circuitry. 
    These flexible connections make it possible to position and connect component-bearing rigid circuit boards functionally in difficult spatial configurations, thus saving space.

    Rigid-flex technology will open up for evermore applications through standardization of materials and processes, especially considering the aspects of system costs and testability / reliability. FLEX &RIGID-FLEX CAPABILITIES

    Flexible Printed Circuit Technology
    DuPont™ Kapton® polyimide film has been used in the electronics industry for over 40 years. Kapton® has excellent dielectric strength, thermal stability, chemical resistance, flexibility, and dimensional stability. While Kapton® is widely used in electrical applications such as insulation for field coils, motor and generator liners, as well as wire and cable insulation, it is particularly well suited for use as a dielectric substrate for flexible copper clad laminate. In fact, flexible circuit laminate is the largest single end use for Kapton® today. Kapton® HN is the primary dielectric core for adhesive based flexible circuits.
    Adhesive Based Flex Circuit Laminate
    Adhesive based flexible laminates are comprised of Kapton® film coated with adhesive on one or both sides and subsequently laminated to copper. There are two kinds of adhesive used in flex, epoxy and acrylic. They each have positive and negative attributes that may make one or the other more suitable for a specific end use. In some applications like actuator circuits for hard disk drives, the adhesive actually performs the critical function of keeping the copper in the "neutral axis". This enables the flex to bend many millions of cycles without failure. However, both acrylic and epoxy adhesives have inferior mechanical and electrical properties as compared to the Kapton® core. In certain applications, the presence of an adhesive layer actually inhibits the use of flexible circuits. Therefore, a solution was needed to eliminate the adhesive layer from the substrate.
    Adhesiveless Flex Circuit Laminate
    In response to this challenge, DuPont developed an all-polyimide laminate that incorporates a bondable polyimide adhesive at the surface to secure the copper foil. This laminate, named DuPont™ Pyralux® AP, opened the door to many new applications for flexible circuits. One example is high layer count rigid-flex boards. In this application, the adhesives’ high coefficient of thermal expansion (CTE) in the Z-axis created reliability problems when exposing the board to thermal cycling. The introduction of Pyralux® AP allowed the design and fabrication of rigid flex and multi-layer flex circuits with much higher layer counts and hole densities.
    Also, with a maximum operating temperature (MOT) of 180C, compared to 105C for typical adhesive based laminates, many higher temperature applications became feasible. Its superior chemical resistance enabled the use of flex circuits in much harsher environments, such as that found in "under-the-hood" automotive applications. Probably most important, though, is the improvement in electrical properties. Adhesive based laminate systems have higher loss tangents and dielectric constants (Dk) and consequently, very high signal attenuation, especially at high frequencies. Pyralux® AP has a lower Dk that remains stable well into the Gigahertz range. Further, because it is available in a thickness of up to 20 mils, Pyralux® AP is ideal for circuitry requiring impedance control.
    As the need for adhesiveless-based laminates began to emerge in the consumer market, DuPont developed an all-polyimide cast-on-copper laminate called DuPont™ Pyralux® AC. This laminate is produced in roll form, thus allowing roll-to-roll flex fabrication for high volume manufacturing. Additionally, this material is available in dielectrics as low as 20 um, allowing for increased flexibility, thinner form factors and lighter weight, all of which are key to the consumer electronics market.

    Flexible and Rigid-Flexible PCBs

    Flexible and rigid-flexible printed circuit board
    Flexible and rigid-flexible printed circuit boards usually cause difficulties in handling. To fix the boards on a work surface can cause some problems. To make the handling easier almost all LPKF systems can be equipped with a vacuum table. Reason to equip the circuit board plotter with a vacuum table is not only a safer positioning of the material, it is also to make the handling of the machine faster and more simple.

    Since the base material of flexible printed circuit boards is always softer, HF tools are primarily used for the milling process. Another advantage of the HF tools is that they do not penetrate deeply into the material. Structuring a flexible printed circuit board is based on the same milling process of rigid base materials.

    With rigid-flexible printed circuit boards, flexible PCB’s are connected together with rigid PCB’s. The production of rigid-flexible printed circuit boards is similar to the production of multilayer boards. The rigid PCB’s are structured in a panel, the area where the flexible portion is to be inserted remains unstructured in the panel, and is covered with a protective foil. The flexible PCB is then pressed upon the already structured rigid areas. Finally, the unstructured area beneath the flexible printed circuit board is milled away.

    For manufacturing rigid-flexible boards, standard LPKF systems can be used. Flexible and rigid-flexible PCBs are easily manufactured in your own electronics lab by plotters of the LPKF ProtoMat S-Series and H-Series.

    Flexible and Rigid-Flexible Board Examples
    Polyimide can also be used as a laminate core in non-flex circuit applications. Recently DuPont leveraged its extensive dispersion technology to fill polyimides with organic and inorganic materials in order to achieve enhanced and/or unique properties. DuPont™ Interra™ HK laminates use this technology for the purpose of embedding planar capacitance in printed circuit boards. Because polyimide film does not contain any woven fabric reinforcement, there is no concern for conductive anodic filaments (CAF), no matter how thin the dielectric.
    Another product that takes advantage of dispersion technology in polyimides is DuPont TC. For this material, thermally conductive fillers are used to enhance the transfer of heat through the laminate without significant loss in dielectric strength. Applications include heating and cooling elements for thermoelectric modules as well as insulated metal and direct bond substrates.
    Polyimide laminate technology has been the foundation of the flex circuit industry for many years. With the introduction of adhesiveless laminates, the possible uses for flex circuits have greatly expanded. With the development of filled polyimide technology, DuPont is continuing to lay the groundwork for the continued use of polyimide laminates well into the future in new and exciting applications in a broad range of markets.

    The trick to developing good inks seems to be to design a mechanism
    for applying the desired conductive material in a form that retains
    flexibility, adhesion, and good conductivity. There are a lot of
    issues that determine the final conductivity of the deposited material.

    Though it is hardly an original thought, what I would really like to
    be able to do is apply conductive, resistive, and suitable dialectric
    materials using an inkjet process on a variety of appropriate
    substrate materials. The goal would be to create all of the 'glue'
    components - bypass caps, resistors, traces and pads to minimize the
    fabrication cost and/or effort for one off prototypes.
