HANDLING CHIP COMPONENTS 1-1
PCS 104 437
© WARNING
All ICs and many other semiconductors are susceptible to
electrostatic discharges (ESD). Careless handling during
repair can reduce life drastically.
When repairing, make sure that you are connected with the
same potential as the mass of the set via a wristband with
resistance. Keep components and tools at this potential.
f ATTENTION
Tous les IC et beaucoup d ´autres semi-conducteurs sont
sensibles aux d écharges statiques (ESD). Leur long évite
pourrait être consid érablement écourt ée par le fait qu ´aucune
précaution n ést prise à leur manipulation.
Lors de r éparations, s ´assurer de bien être reli é au m ême
potentiel que la masse de l ´appareil et enfileer le bracelet
serti d ´une r ésistance de s écurit é.
Veiller à ce que les composants ainsi que les outils que l ´on
utilise soient également à ce potentiel.
d WARNUNG
Alle ICs und viele andere Halbleiter sind empfindlich
gegen über elektrostatischen Entladungen (ESD).
Unsorgf ältige Behandlung im Reparaturfall kann die
Lebensdauer drastisch reduzieren.
Sorgen Sie daf ür, da ß Sie im Reparaturfall über ein Puls-
armband mit Widerstand mit dem Massepotential des
Gerätes verbunden sind.
Halten Sie Bauteile und Hilfsmittel ebenfalls auf diesem
Potential.
ñ WAARSCHUWING
Alle IC ´s en vele andere halfgeleiders zijn gevoelig voor
electrostatische ontladingen (ESD).
Onzorgvuldig behandelen tijdens reparatie kan de levensduur
drastisch doen vermindern. Zorg ervoor dat u tijdens reparat ie
via een polsband met weerstand verbonden bent met hetzelfde
potentiaal als de massa van het apparaat.
Houd componenten en hulpmiddelen ook op ditzelfde potentiaal .
i AVVERTIMENTO
Tutti IC e parecchi semi-conduttori sono sensibili alle scar iche
statiche (ESD).
La loro longevit à potrebbe essere fortemente ridatta in caso di
non osservazione della pi ù grande cauzione alla loro
manipolazione. Durante le riparationi occorre quindi essere
collegato allo stesso potenziale che quello della massa
delápparecchio tramite un braccialetto a resistenza.
Assicurarsi che i componenti e anche gli utensili con quali si
lavora siano anche a questo potenziale.
©
Safety regulations require that the set be restored to its
original condition and that parts which are identical with
those specified be used.

After servicing and before returning the set to customer
perform a leakage current measurement test from all
exposed metal parts to earth ground, to assure no
shock hazard exists.
The leakage current must not exceed 0.5mA.
