VERFAHREN ZUR HERSTELLUNG KONTAKTLOSER CHIPKARTEN SOWIE ZUR HERSTELLUNG VON ELEKTRISCHEN EINHEITEN, BESTEHEND AUS CHIPS MIT KONTAKTELEMENTEN

摘要

The invention relates to a method for production of electrical units comprising chips with contact elements, whereby said contact elements are suitable for making electrically conductive connections with the contact terminals of external electrical components. Said contact element connections with the chips are made before said chips are released from the grouping into rows and columns as defined on the wafer. Said contact element comprises a metallised plastic or metallic foil to be brought into contact with the chips.
