Primordial Black Hole (PBH) formation can be enhanced by the presence of strongly coupled scalar and spinor fields during the primeval radiative expansion. We outline that the likelihood of PBH formation exhibits a sudden burst if the spinor field acquires a Higgs mass $m_H$. The typical PBH mass scale then exhibits a specific dependence on $m_H$. For $m_H \sim 100$ eV, and coupling set by $\beta \sim 10$, the possibility to form PBH exhibits a peak between $10^8$ and $10^9 M_\odot$
