ʻO ka PCB multilayerka mea nui i haku ʻia me ka foil keleawe, prepreg, a me ka papa kumu. ʻElua ʻano o nā hale lamination, ʻo ia hoʻi, ke ʻano lamination o ka pahu keleawe a me ka papa kumu a me ke ʻano lamination o ka papa kumu a me ka papa kumu. ʻOi aku ka maikaʻi o ka pahu keleawe a me ka papa hana lamination, a hiki ke hoʻohana ʻia ka papa hana lamination no nā papa kūikawā (e like me Rogess44350, etc.) nā papa multi-layer a me nā papa kūkulu hybrid.
1. Hoʻolālā i nā koi no ka paʻi ʻana i ka hale I mea e hōʻemi ai i ka warpage o ka PCB, pono e hoʻokō ka ʻōnaehana lamination PCB i nā koi symmetry, ʻo ia hoʻi, ka mānoanoa o ke keleawe keleawe, ke ʻano a me ka mānoanoa o ka papa dielectric, ke ʻano hoʻohālike. (papa kaapuni, papa mokulele), ka lamination, etc. pili i ka PCB vertical Centrosymmetric,
2.Conductor keleawe mānoanoa
(1) ʻO ka mānoanoa o ke keleawe conductor i hōʻike ʻia ma ke kaha kiʻi ʻo ka mānoanoa o ke keleawe i hoʻopau ʻia, ʻo ia hoʻi, ʻo ka mānoanoa o ka papa o waho o ke keleawe ka mānoanoa o ka pahu keleawe lalo a me ka mānoanoa o ka papa electroplating, a me ka mānoanoa. o ka papa keleawe o loko ka mānoanoa o ka papa o loko o ka pahu keleawe lalo. Ma ke kaha kiʻi, hōʻailona ʻia ka mānoanoa keleawe o waho ma ke ʻano he "copper foil mānoanoa + plating, a ʻo ka mānoanoa keleawe o loko i kaha ʻia ʻo "copper foil mānoanoa".
(2) Pono e hoʻohana like me ka hoʻohana ʻana i ka 2OZ a ma luna o ke keleawe mānoanoa o lalo.
E hōʻalo i ka waiho ʻana iā lākou ma nā papa L2 a me Ln-2 e like me ka mea hiki, ʻo ia hoʻi, nā papa lua o waho o ka ʻili o luna a me lalo, i pale aku i nā ʻili PCB ʻaʻole like ʻole a wrinkled.
3. Nā koi no ke kaomi ʻana i ka hale
ʻO ke kaʻina hana lamination kahi hana nui i ka hana PCB. ʻOi aku ka nui o nā laminations, ʻoi aku ka maikaʻi o ka pololei o ka alignment o nā lua a me ka disk, a ʻoi aku ka koʻikoʻi o ka deformation o ka PCB, ʻoi aku ka nui o ka asymmetrically laminated. Loaʻa i ka lamination nā koi no ka hoʻopaʻa ʻana, e like me ka mānoanoa keleawe a me ka mānoanoa dielectric pono e kūlike.
