Amafayela awusizo afaka phakathi i-Gerbers noma i-ODB++, amafayela okubhoboza, i-BOM, i-centroid, imidwebo, amanothi e-stackup, izidingo ze-impedance, amanothi okuhlela i-firmware, izingxenye ezikhethekile, isikhathi esithandwayo sokuhola, kanye nemigomo yokuqinisekisa ehlosiwe.

Ukuphindaphinda kwe-prototype kungenziwa kanjani ngokushesha?

Ukuphindaphinda kuyashesha uma iphakheji yokuklama isiqediwe, izinkinga ze-DFM ziyalungiswa ngaphambi kokukhishwa, izingxenye ezihola isikhathi eside zitholakala kusenesikhathi, ezinye ziyavunyelwa, i-firmware yokuhlola isilungile, futhi ukubuyekezwa ngakunye kunomgomo wokufunda ocacile.
