1. Mai laminate yana da yanayi mai kyau;

2. Impedance yana da ci gaba;

3. Launin bayanan da ke ƙasa saman farfajiyar ya kamata ya zama cikakkiyar ƙasa ko tushen wuta (yawanci layin na biyu ko layin da zai cike shi);

4. Powerarfin jirgin sama da na ƙasa an haɗa su sosai;

5. Launin siginar yana kusa-kusa yadda ya kamata zuwa layin jirgin sama da yake nuni;

6. Kiyaye tazara tsakanin yadudduka biyu na sigina na kusa kamar yadda ya kamata. The kwatance ne orthogonal;

7. Lawanin tunani guda biyu da ke sama da kasan siginar kasa ce da karfi, yi kokarin takaita tazarar da ke tsakanin layin siginar da layin na kasa;

8. Tazarar siginar banbanci ≤ sau 2 nisan layi;

9. Preregreg tsakanin layin shine ≤3;
