- greater metallization adhesion can be provided in contact with the molding resin.
- the adhesion can be obtained by various known methods: for example, by increasing the roughness of the copper of the circuit, by increasing the surface roughness (the additional metallization type Ni / Pd / Au (nickel, palladium, gold) will follow this roughness, by plasma before molding, by anchoring points of the molding in conductive portions of the metallizations.
- the above substrate may be unpunched, as illustrated in FIG. 2;
- the external contacts 4 may remain copper (possibly protected from oxidation by organic passivation or other surface treatment prior or subsequent).
- the above substrate can be punched, as illustrated in FIG. 1, with a number of holes greater than those necessary to be metallized, in order to facilitate the subsequent separation of the low adhesion support. of the box, the surface facing vis-à-vis being indeed lower
- the contact pads may be perforated to limit adhesion and to save metallizations and / or to allow electromagnetic permeability in the case where the object also comprises a radiofrequency antenna, for example etched on the support.
- an antenna (not shown) is produced, for example at the same level as the contacts or conductive tracks, in particular at the periphery and / or at the center of the contact areas 4 in a central zone 40.

- the delamination of the housings on the substrate is facilitated because the molding is carried out at high temperature (about 180 ° C.) and the adhesive has been chosen to degrade around this temperature. Ejectors 14 sliding on the upper part DMS of the mold, can maintain this substrate on the lower part of the DMI mold.
