4 Layer HASL Impedance Control Kaumaha Copper PCB
ʻO nā pono a me nā hana o ka PCB keleawe kaumaha
Nā hana:
ʻO ka hoʻohana ʻana i ka PCB keleawe kaumaha ma ka PCB hōʻoia ʻana kokoke i nā wahi āpau, a ʻo kāna kahua noi he ākea loa, me nā ʻano mea like ʻole o ka home, nā huahana kiʻekiʻe-ʻenehana, ka pūʻali koa, ka lāʻau lapaʻau a me nā lako uila.ʻO ka PCB keleawe kaumaha ka hana hoʻonui maikaʻi loa, ke kiʻekiʻe wela, ka haʻahaʻa haʻahaʻa, ka pale ʻana i ka corrosion, i ʻoi aku ka lōʻihi o ka lawelawe ʻana o nā huahana uila, akā no ka hoʻomaʻamaʻa ʻana i ka nui o nā lako uila he kōkua nui.ʻO ka mea nui, ʻo ka pono e holo i ka volta kiʻekiʻe a me kēia manawa o nā huahana uila ka pono o ke keleawe kaumaha.
Pono:
I ka hōʻoia ʻana o ka PCB, ʻoi aku ka ikaika o ka PCB keleawe kaumaha a me ka hiki ke hoʻololi.Eia kekahi, he mea kūpono ia no nā kaʻina hana like ʻole a me nā ʻōnaehana e like me ka pā pā hale, ka ʻano kī paʻa paʻa, ʻōnaehana vertical bite, ʻōnaehana BEM, ʻōnaehana wai ua, a me nā mea ʻē aʻe. .
ʻO ka mānoanoa keleawe i loko ≥4oz hoʻopiha piha
No ka PCB me ka hoʻolālā keleawe keleawe koʻikoʻi, i mea e hōʻoia ai i ka hoʻopiha piha ʻana o ke kāpili, hoʻohana pinepine ʻia ka resin paʻi a i ʻole ka pauka PP.Eia naʻe, loaʻa i kēia hopena nā pilikia o ke kaʻina hana lōʻihi a paʻakikī ke kāohi i ka mānoanoa o ka papa dielectric.Hiki i ka pepa adhesive SP ke hoʻokō i nā hiʻohiʻona o ke kiʻekiʻe o ka glue content a me ka mānoanoa kiʻekiʻe.Loaʻa iā ia nā pōmaikaʻi nui no ka hoʻopiha piha ʻana i ke keleawe keleawe kaumaha a hiki ke hoʻopau pono i ka pilikia o ka hoʻopiha ʻana i ke kopa keleawe kaumaha.
Pono o SP Prepreg
ʻO ka hoʻohana ʻana i ka ʻōnaehana resin pale wela, me ke kūpaʻa wela kiʻekiʻe
Hoʻohana i ka ʻōnaehana hoʻonui haʻahaʻa
ʻO ka ʻike resin kiʻekiʻe kiʻekiʻe a me ka porosity maikaʻi e loaʻa iā ia kahi mana hoʻopihapiha maikaʻi loa
Hoʻopau ke kiko aniani kūikawā i nā kiko koʻikoʻi a hoʻomaikaʻi i ka hilinaʻi.
