Yes, on request we can supply your IMS printed circuit boards with UL certificate (UL94 / V-0). Please select this free option in the calculator for metal core PCBs.
At high frequencies, conductor tracks must be considered as components, as they influence the signal behaviour. Defined impedances (characteristic impedance), a homogeneous layer structure and…
We process specially developed HF materials such as Rogers (RO4000, RO3000), PTFE or Megtron 6. These are characterised by a constant dielectric constant (εr), a very low dissipation factor (Df) ,…
The impedance (characteristic impedance) must match the transmitter and receiver components exactly, otherwise signal reflections, losses and distortions will occur. We calculate the required…
Yes, in many cases a customised FR4 structure is sufficient for the outer layers. For higher demands hybrid buildups (also sandwich structures) with a combination of HF materials (e.g. Rogers) and…
You calculate and order directly via our circuit board calculator. Select the impedance check option there and send us your specifications regarding impedance and layer structure with the data. Every…
The Tg value (glass transition temperature) is the temperature at which the base material changes from a glassy-brittle to a soft-elastic state. From a Tg of 170 °C, we speak of high-Tg material.…
No. The Tg value is not a permanently permissible application temperature. If it is exceeded, the resin matrix will decompose and delamination may occur. The following applies as a guideline for…
The CTE-z value describes the thermal expansion in the thickness (z-axis). A low CTE-z value - as is usual with high-Tg PCBs - is crucial for the reliability of the vias under thermal stress. It…
Yes, indirectly. CAF (Conductive Anodic Filament) refers to the unwanted growth of conductive filaments along glass fibres. Many high-Tg materials (such as ISOLA IS410 or 370HR) are explicitly…
