<p>In the mfr. of appts. for the electrolytic treatment of the bases of electronic components (transistors, integrated circuits etc.) the mounting is such that it ensures the passage of the cathode current to the point to be coated. Specifically the appts. comprises a number of assemblies which may vary depending on the use. Pref. the appts: comprises a metal support to which is fixed a spring which makes the contact with the base to be coated, a pliable plastic conductor (I) and an outer coating of non-conducting material. Appts. does not need any fine adjustment for its efficient working and the points of contact need not be defined in advance. (I) can be easily changed to comply with the current need. (I) may be renovated by demetallisation.</p> |
