Material Notes:
Alloy especially suited to applications in electronics and electro technology. This doped copper, displays high electrical and thermal conductivity, good mechanical properties and excellent temperature stability. CUPROFOR® is used in the manufacture of high power transistor supports, integrated circuits, electrical contacts and shunts.Applications: ElectronicsHeat sinks for power transistorsCUPROFOR® properties includeThermal conductivity to dissipate heatTemperature resistance permitting Pb/Sn soldering of the chip without loss of mechanical properties Mechanical strength to prevent deformation of heat dissipaters when moulding. CUPROFOR® can play an important part in the manufacture of power transistor heat sinks.For this application, CLAL offer 1/2 hard profile strips (condition TL2) in long length coils which can be delivered :totally or partially Ni coated, with an inlay of Pb/Sn, Ag or other material.Support media for printed circuitsThis application uses the following properties :temperature resistance, thus permitting the soldering of the integrated circuit of the DIE PAD, without loss of hardness in the support mediaOutstanding mechanical properties which guarantees the mechanical strength of the LEADSA high deformation capacity gives suitability to form external LEADS.For this application, CLAL, upon request offer long length tapes : a high standard of geometrical and dimensional accuracya stress relieving treatment to maintain that the LEADS TIPS are coplanar about the DIE PAD.The electro-technical fieldElectrical contactsContact mountsPushbuttonsConductive partsElectrical connections and terminals.Other fieldsHeat exchangersSeals and washersDephasing rings.Information provided by CLAL-MSX
