Hana ʻia ka substrate o ka papa PCB ponoʻī i nā mea hoʻopili a me nā mea hoʻoheheʻe wela ʻaʻole maʻalahi e piʻo. ʻO nā mea kaapuni liʻiliʻi i hiki ke ʻike ʻia ma ka ʻaoʻao he pā hao keleawe. Ua uhi mua ʻia ka pepa keleawe ma luna o ka papa PCB holoʻokoʻa, akā ua kahakaha ʻia kahi ʻāpana i ka wā o ke kaʻina hana, a ʻo ka hapa i koe i lilo i pūnaewele o NS liʻiliʻi. Kapa ʻia kēia mau laina i nā uea a i ʻole nā ​​ueaea, a hoʻohana ʻia e hoʻolako i nā pilina kaapuni no nā ʻāpana ma ka PCB.

ʻO ka maʻamau ke kala o ka papa PCB he ʻōmaʻomaʻo a ʻeleʻele paha, ʻo ia ke kala o ka mask mask. ʻO ia kahi pale pale pale insulate i hiki ke pale i ka uea keleawe a pale i nā ʻāpana mai ka wili ʻia i kahi hewa. Hoʻohana ʻia nā papa multilayer i kēia manawa ma nā papa makuahine a me nā kāleka kiʻi, e hoʻonui nui nei i ka wahi i hiki ke hoʻopaʻa uila.

Pehea e ʻike ai i ka helu o nā papa o ka papa PCB motherboard
Nā Papa Hana / Nā Hana
Hoʻohana nā papa multilayer i nā papa kuʻikuʻi ʻelua a ʻelua paha, a kau i kahi papa o ka papa insulate ma waena o kēlā me kēia papa o nā papa a kaomi pū iā lākou.

Pehea e ʻike ai i ka helu o nā papa o ka papa PCB motherboard

ʻO ka helu o nā papa o ka papa PCB ʻo ia hoʻi aia kekahi mau papa uila kūʻokoʻa. ʻO ka maʻamau ka helu o nā papa a loaʻa nā ʻaoʻao ʻelua i waho. Loaʻa nā papa PCB maʻamau i kahi hanana o 4 a 8 mau papa. Hiki ke ʻike ʻia ka helu o nā papa o nā papa PCB he nui e ka nānā ʻana i ka ʻoki o ka papa PCB. Akā i ka ʻoiaʻiʻo, ʻaʻole hiki i kekahi ke ʻike maka maikaʻi loa. No laila, e aʻo wau iā ʻoe i kekahi ʻano hana hou ma lalo.

ʻO ke kaapuni kaapuni o ka papa multi-layer ma o ke kanu ʻia ʻana ma o a makapō ma o ka ʻenehana. Hoʻohana ka hapa nui o nā papa makuahine a me nā kāleka hōʻike i 4-layer PCB papa, a hoʻohana kekahi i nā papa PCB 6, 8, a i ʻole 10-layer PCB.

Inā makemake ʻoe e ʻike i ka nui o nā papa o ka PCB, hiki iā ʻoe ke hoʻomaopopo iā ia ma ka nānā ʻana i nā puka, no ka mea, ʻo nā papa 4-layer i hoʻohana ʻia ma ka motherboard a me ka pepa hōʻike he mau hiʻohiʻona ia ma nā papa mua a me ka ʻehā, a ʻo kekahi mau papa ʻē aʻe. hoʻohana (uea lepo). A me ka lako mana). No laila, e like me ka papa papa pālua, e komo ka puka ma waena i ka PCB papa.

Inā kū kekahi mau vias ma mua o ka PCB akā ʻaʻole hiki ke loaʻa ma ka huli, a laila he papa 6/8-layer ia. Inā loaʻa ka like ma o nā puka ma nā ʻaoʻao ʻelua o ka PCB, he papa 4-layer maoli ia.
