Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for treating electronic card surfaces with plasma to minimize surface tension are inefficient, leading to adherence defects in protective layers or binders, resulting in suboptimal card quality.
Innovation Solution

Engineering Contradiction Analysis
1Reliability
If plasma torch projection is used to treat card surfaces, then surface tension is minimized and adherence is improved, but treatment uniformity across multiple surfaces at various heights deteriorates
Solution Approach 1:
The space above the card is segmented into multiple strata (first stratum, second stratum, etc.) based on height levels. Each stratum contains specific surfaces at particular heights, allowing the plasma torch to treat surfaces in organized layers, ensuring uniform treatment across complex 3D geometries
Solution Approach 2:
The plasma torch follows a dynamically generated trajectory that adapts to the card's surface topology. The trajectory ensures the torch remains within an ideal working range distance from each surface while moving systematically through all strata, maintaining consistent treatment quality across surfaces at varying heights
2Area of stationary object
If conventional plasma treatment is applied to all surfaces, then treatment coverage is achieved, but adherence defects occur due to inconsistent surface tension
Solution Approach 1:
The system uses a predetermined ideal working range as a feedback criterion to control plasma torch positioning. The trajectory generation ensures the torch continuously maintains distance within this optimal range from each surface being treated, preventing adherence defects by ensuring consistent treatment parameters across all covered areas
Solution Approach 2:
The treatment approach adapts to local surface characteristics by determining specific strata for different height levels. Each stratum receives tailored treatment through the trajectory control system, ensuring that local variations in surface position do not compromise overall adherence quality

AI summary
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).
