I ka hoʻolālā o PCB, ʻaʻole lawa ka ʻike o nā hoa aloha he nui e pili ana i nā papa ma PCB, keu hoʻi ka novice, maopopo ʻole ke kuleana o kēlā me kēia papa. I kēia manawa, e nānā i ka papa kaha kiʻi AlTIumDesigner, he aha nā ʻokoʻa o kēlā me kēia papa.

1. Pākuʻi hōʻailona

Hoʻokaʻawale ʻia ka papa hōʻailona i TopLayer (TopLayer) a me BottomLayer (BottomLayer), i loaʻa nā pilina uila a hiki ke hoʻokau i nā ʻāpana a me nā kaula.

2. Pākuʻi mīkini

ʻO ka mīkini ka wehewehe o ka helehelena o ka papa PCB holoʻokoʻa. ʻO ke koʻikoʻi ma “Mekanika” ʻaʻole ia he waiwai uila, no laila hiki ke hoʻohana palekana ʻia no ke kiʻi ʻana i nā kinona, ke kaha ʻana i nā ana Mekanika, ke kau ʻana i nā huaʻōlelo, a pēlā aku, me ka hopohopo ʻole e pili ana i nā loli i nā pono uila o ka papa. Hiki ke koho ʻia i kahi kiʻekiʻena o 16 mau papa mechanical.

3. Papa paʻi paʻi

Hoʻohana ʻia ʻo Top Overlay a me Bottom Overlay e wehewehe i nā hua paʻi paʻi ʻo Top a me lalo. ʻO lākou nā hōʻailona kikokikona i paʻi ʻia ma luna o ka papa pale pale solder, e like me ka inoa o ka ʻāpana, ka hōʻailona o nā ʻāpana, nā pinana a me nā kuleana kope, e kōkua ai i ka hoʻopili uila ʻana a me ka nānā hewa ʻana.

4. Pā pala pala pi

Hoʻopili ka waihona Pasta solder i ka papa Paste Top a me ka paina Pasta ma lalo, kahi e pili ana i ka papa Paste papa i hiki iā mākou ke ʻike ma waho, ʻo ia hoʻi, ka ʻāpana e pono ai ke uhi ʻia me ka Paki Palder ma mua o ka hoʻopili ʻana. No laila he mea pono kēia papa i ka lewa wela o ka pad a e hana ana i ke kila kila.

5. kuʻihao kuʻihao kuʻihao

Kāhea ʻia ʻo Solder layer ma ke ʻano he “windowing-out,” me TopSolder a me BottomSolder, kahi hana ʻē aʻe i ka solder paste a kuhikuhi i ka papa e uhi i ka aila ʻōmaʻomaʻo. Māhele ka papa i mea pale ʻole e pale i ke kaapuni pōkole o ka nui o ka solder ma nā hono e pili ana i ka wā o ka hao. Uhi ka pale pale kuʻupuʻu i ka uea kiʻi keleawe a pale i ke kiʻi ʻāpana keleawe mai ka hoʻowīwīwī ʻana i ka lewa, akā hoʻokaʻawale ʻia ke kūlana ma ka hui solder a ʻaʻole uhi i ka hui paʻa.

ʻO ka uhi keleawe keleawe a i ʻole nā ​​uea ka uhi paʻamau o ka aila ʻōmaʻomaʻo, inā pili mākou i ka mālama ʻana i ka papa solder, e pale i ka ʻaila ʻōmaʻomaʻo e uhi, e hōʻike i ke keleawe.

6. ʻeliʻeli

ʻO ka papa drill o DrillGride a me DrillDrawing. Hoʻohana ʻia ka papa drill e hāʻawi i ka ʻike e pili ana i nā lua drill i ke kaʻina hana papa kaapuni (e like me nā pads, e pono ai e ʻeli ʻia ma o nā puka).

7, pāpā pāpā paʻa pāpā i ka papa uila (KeepOutLayer) i hoʻohana ʻia e wehewehe i ka palena o ka pae uila, ma hope o ka wehewehe ʻana i ka papa uila pāpā, i ke kaʻina uila e hiki mai ana, me nā ʻano uila ʻaʻole hiki ke ʻoi aku i ka palena o ka pāpā pāpā pāpā.

8. Pā-maha

Pono nā pads a me nā puka komo i ka papa kaapuni e komo i ka papa kaapuni āpau a hoʻokumu i nā pilina uila me nā papa kiʻi conductive like ʻole, no laila hoʻonohonoho pono ka ʻōnaehana i kahi papa abstract – multi-layer. ʻO ka maʻamau, hoʻonohonoho ʻia nā pads a me nā puka ma nā papa he nui, a inā paʻa kēia papa, ʻaʻole e hōʻike ʻia nā pads a me nā lua.
