2 Layer i ka ehī hapalua puka PCB 14146

ʻO ka lua hapa metala (ʻeleu) kahi puka ma hope o ka lua ma hope o ka ʻeli ʻana ʻelua, ke ʻano o ke ʻano, a paʻa hope i ka lua metala (ʻeleu) hapalua, ʻōlelo wale ʻia ua ʻoki ʻia ka lua o ka pā i ka hapalua, ke kaʻina o ka papa semi-metallic hole. he hana makua loa.

Pehea e kaohi ai i ka maikaʻi o ka huahana ma hope o ka hoʻokumu ʻana i ka lua semi-metallic hole ma ka lihi o ka pā. E like me ka puka o ka paia keleawe prickle, residual kahi hana paʻakikī. ʻO kahi lālani piha o nā lua semi-metallized ma ka lihi o ia mau papa PCB, i hōʻike ʻia e kahi puka liʻiliʻi, hoʻohana nui ʻia ma ka papa, ma ke ʻano he subplate o kahi papa haku, kahi e hoʻopili ʻia ai nā puka semi-metallized i nā pine o ka ka papa haku a me nā ʻāpana.

Inā he mau keleawe keleawe i loko o ka lua semi-metallized, ke paʻa pono ka mea hana, e alakaʻi ia i ka wāwae wili, paʻa pono ʻole ia, ʻo ia ke kumu no ke alahaka ma waena o nā pine pōkole ʻelua. ʻO ka ʻeli ʻana a me ka wili pū ʻana, ke kuhikuhi o ka huli ʻana o ka SPINDLE i ka uaki, e pale ana i ka hoʻonui ʻia o ka papa metallization i ka wā o ka hana ʻana a me ka hoʻokaʻawale ʻana o ka papa metallization mai ka paia o ka lua, a me ka hōʻoia ʻana ʻaʻole e hana ʻia nā koʻi keleawe a me nā koena ma hope o ka hana ʻana. . E ʻoi aku ka nui ma mua o ka gong kosong.
