2 Layer HASL FR4 Half Hole PCB

ʻO ka hapalua metala (groove) he puka ma hope o ka lua ma hope o ka lua o ka hoʻoheheʻe ʻana, ke kaʻina hana, a hoʻopaʻa hope i ka lua metala (groove) hapalua, ʻōlelo wale ʻia ʻo ka ʻaoʻao o ka pā metala i ʻoki ʻia i ka hapalua, ka ʻaoʻao o ka pā semi-metallic puka kaʻina. he hana oo loa.

Pehea e hoʻomalu ai i ka maikaʻi o ka huahana ma hope o ka hana ʻana i ka lua semi-metallic ma ka lihi o ka pā.E like me ka hole wall copper prickle, koena he hana paʻakikī.He lālani piha o nā puka semi-metala ma ka ʻaoʻao o ia mau papa PCB, i hōʻike ʻia e kahi puka liʻiliʻi, i hoʻohana nui ʻia ma ka papa, ma ke ʻano he subplate o ka master plate, kahi e hoʻopaʻa ʻia ai nā lua semi-metala i nā pine o ka papa haku a me nā ʻāpana.

Inā he keleawe spines i loko o ka semi-metala lua, i ka wa a ka mea hana kuʻihao, e alakai i ka kuʻi wāwae 'aʻole paʻa, virtual kuʻihao, koʻikoʻi e kumu alahaka ma waena o nā pine ʻelua pōkole kaapuni.ʻO ka wili ʻana a me ka wili ʻana, ʻo ke kuhikuhi ʻana o ka rotation o ka SPINDLE ma ke ʻano uaki, e pale ana i ka hoʻonui ʻia ʻana 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 spine keleawe a me nā koena ma hope o ka hana ʻana. .E ʻoi aku ka nui ma mua o ka ʻāpana gong.
