Special PCB technologies

LeitOn Special Technologies

Besides our online calculation with mostly standardised printed circuit board types we do offer a wide range of special technologies. Sometimes, these special technologies simply base on standard PCBs and come as an "upgrade" that need special care an manufacturing capabilities. Working with uncommon and special materials in printed circuit board production is one of our strengths. Following, you can find a range of special technologies and projects, starting from stainless-steel multilayers, copper-core heat-sing PCBs, semi-flexible printed circuits, aluminium IMS PCBs and much more . In case you have any questions or requirements that exceed below projects, please do not hesitate to contact us. Challenge us!

  • Rigid-Flexible Printed Circuits

    Rigid-Flexible
    Printed Circuits (RFPCB)

    Rigid-flexible PCBs combine conventional "rigid" circuit boards with flexible parts. A rigid-flexible PCB (RFPCB) can therefore replace several rigid PCBs which otherwise have to be connected with cables and connectors.

  • Pure-FR4-Rigid-Flex

    Pure-FR4-
    Rigid-Flex

    These rigid-flexible PCBs are of "pure" FR4 and do not contain any polyimide. This is advantageous for applications in humid environments because the hygroscpic characteristics are much better than fpr standard RFPCBs.

    Semi-Flexible Printed Circuits

    Semi-Flexible
    Printed Circuits

    With an accurate depth-milling a standard printed circuit board can be prepared for flexible installations. So called "semi-flexible" printed circuits save cables and connectors but are relatively cheap to produce as PCBs.

    Impendance Controlled PCBs

    Impendance Controlled
    PCBs

    Impedance controlled printed circuits are important for high frequencies. Signals may overlap or erase themselv due to reflections, if impedance are ignored. This may lead to spontaneous errors of the application.

    Hoch-Tg Leiterplatten

    High-TG
    PCBs

    High-TG materials are materials that can sustain maximum operating temperatures of around 150°C and more. Such materials have a TG of 170°C. Some polyimide materials can go above 200°C and still operate reliably.

    IMS-Aluminium-PCBs

    IMS-Aluminium-
    PCBs

    Aluminium-PCBs, or IMS (Insulated Metal Substrate) printed circuits offer cost-efficient solution to manage heat for high-performance LED-technology or transistor-electronics. An aluminium base efficiently dissipates heat.

  • Schwarze FR4 Leiterplatten

    Schwarze FR4
    Leiterplatten

    Next to its sheer "cool" look of completely black FR4 materials (also the edges), there is a simple technical use for them: light-sensitive applications where sensors should not be exposed to uncontrolled light sources.

  • 400µm Copper PCBs

    400µm Copper
    PCBs

    Printed circuits with double sided 400µm copper are without doubt the king of high-copper-clad PCBs. Using such massive copper cladding you can operate massive currents. A innovative solder mask-process assures perfect looks.

  • Endless-Snake Flexible Printed Circuits

    Endless-Snake Flexible
    Printed Circuits

    Using a smart „snake“-layout trick and pre-applied 3M double side-adhesive, one can design easy to assemble, meter-long flexible pritned circuits. Such snakes can easily rech 10 meter without having to pay for extra over-size toolings.

  • Half-Open Edges PCBs

    Half-Open Edges
    PCBs

    The higher level of plated edges is the so called half-open technology for printed circuits. Plated drills are cut in half on the outline of the PCB. What looks so simple requires precise and well plannes production steps to assure they hold tight.

  • Copper-Core Heat-Sink-PCBs

    Copper-Core
    Heat-Sink-PCBs

    Into a 4,2mm thick stack-up we have implemented two 1,8mm solid-copper-cores with additional heat-sink-blind-vias. In between, complex signal layers are transporting information. Heat-management and signals on one board.

  • Stainless-Steel Multilayer PCBs

    Stainless-Steel
    Multilayer PCBs

    For perfect shielding of coils in a printed circuit we included a 0,3mm stainless steel plate into a 9-layer-hybrid-multilayer. For stainless steel lamination a range of processes were required in order to make this stack-up hold tight.
