Abstract:
The invention relates to a method for treating surfaces of an electronic card (4) by means of a plasma torch (1), said card (4) comprising a plurality of electronic components (C1a, C1b, C1c, C2a, C2b, C3a) and a plurality of surfaces to be treated, arranged at various heights relative to a reference plane (Ref) of the electronic card (4). At least one region to be treated (Zn) containing the surfaces to be treated is determined, strata (S1, S2, S3) which are parallel to said reference plane (Ref) and each contain at least one surface to be treated are determined, and then a torch movement path is generated such that: the surfaces are treated, stratum by stratum; for each stratum, the torch is exclusively moved in parallel with the reference plane (Ref); during the projection of the plasma flow (2), each treated surface is exclusively placed in the ideal working zone (Pt).
