  1. Patentkrav
    1Ö
    1„ Fremgangsmåde til regenerering af en beskadiget elektronisk indretning ved mindst en renseproces og mindst en tørreproces, hvor renseprocessen omfatter trinene:
    - nedsænkning af en eller flere elektroniske indretninger i en vandig rensevæske i et rensekammer (i),
    - udsættelse af den vandige rensevæske og de en eller liere elektroniske indretninger for ultralydslysering, hvor tørreprocessen omfatter trinet:
    ~ tørring af de en eller tiere elektronikindretninger, hvori torring af de en eller flere elektroniske Indretninger udfores ved periodisk opvarmning af rensekammeret, mens rensekammeret er underkastet reduceret tryk, og hvor rensettinet og tørrettinet udfores i samme rensekammer (1), kendetegnet ved at fyldning af rensekammeret med væske udføres ved at det mindst ene pumpeorgan (6) sætter rensekammeret under et reduceret tryk og derved suger den vandige rensevæske ind i rensekammeret gennem det mindst ene væskemdløbsorgan (7, 14, 25, 31).
