SMD-Series

This catalogue of coilformers contains information on all our products of the SMD-Series (Surface Mounted Devices)

Miniature electronic components, surface mountable, are used in ever increasing numbers in many areas of electronics. The requirements are: smallest dimensions, high temperature rating and fast solderability.

We supply coilformers in high quality thermoplastics, exactly to meet your production requirements ans product specification.

Wherever high-temperature soldering processes are used in connection with SMD-series coilformers, we recommend irradiated cross-linked plastics. This ensures that the mechanical properties - in particular those of gfr-polyamides - are maintained and breakages are reduced. For this reason NORWE offers all plastics components of the SMD-series in irradiated cross-linked materials.

In the short term, the cross-linked materials can be exposed to very high temperatures. Apart from improved aspects in production there may be interesting cost advantages, and a discussion with us could be useful.

Should you need further assistance we look forward to hearing from you.

Our extensive range of modular tooling allows almost unlimited constructional changes to meet customers specification, often by simple changes of tool inserts.

In addition the modular tooling system allows extremely short tooling times and can be very cost effective.

EE-SMD Coilformers (fm)
