4 Layer ENIG FR4 Kaumaha PCB
PCB keleawe kaumaha
Hiki ke hana ʻia nā papa PCB keleawe kaumaha ma o ka hui pū ʻana o ʻelua kaʻina hana nui, electroplating a me etching.ʻOkoʻa me nā PCBS ʻē aʻe, ua hana ʻia ke kaapuni me kahi ʻāpana lahilahi o ka foil keleawe.
Hoʻopili ʻia nā PCB keleawe kaumaha me FR4 a i ʻole nā mea epoxy-based.ʻO ka awelika kaumaha o nā PCB keleawe kaumaha he 4 auneke (140μm), ʻoi aku ka maikaʻi ma mua o kekahi PCB keleawe maʻamau.
ʻO ka mānoanoa keleawe hou aʻe e hiki ai i ka papa ke alakaʻi i nā au kiʻekiʻe, e loaʻa i ka puʻu wela maikaʻi, a hiki i ka hoʻololi paʻakikī i kahi ākea.ʻO nā mea maikaʻi ʻē aʻe e pili ana i ka hoʻonui ʻana i ka ikaika mechanical ma nā wahi hoʻohui, ka hiki ke hana i ka nui o nā huahana liʻiliʻi ma o ka hoʻohui ʻana i nā kaupaona he nui i ka papa hoʻokahi o ke kaapuni, a me ka hiki ke hoʻohana i nā mea kūikawā me ka liʻiliʻi liʻiliʻi o ka hemahema kaapuni.
Nā pōmaikaʻi o ke keleawe keleawe kaumaha PCB
ʻO ka hana ʻana i nā PCB keleawe kaumaha e pili ana i ka hoʻohana ʻana i ka plating a i ʻole etching, no ka mea e hoʻonui i ka mānoanoa o ka PCB keleawe ma nā paia ʻaoʻao a me nā lua plating.Eia kekahi, hoʻopili ʻia nā PCBS keleawe kaumaha i ka wā hana PCB.Kōkua kēia i ka mānoanoa o ka pā PTH ma ka PCB.ʻO kekahi mau hiʻohiʻona o ka PCBS keleawe mānoanoa i ʻokoʻa mai nā PCBS ʻē aʻe:
Kaumaha keleawe:
ʻO kēia ka mea nui o ka PCB keleawe kaumaha.E pili ana ia i ke kaumaha o ke keleawe i hoʻohana ʻia i kēlā me kēia kapuaʻi kūhāhā i nā auneke.
Uhi
Pepa keleawe waho.ʻO ke kaumaha keleawe o ka papa waho kahi hoʻolālā maʻamau i hoʻonohonoho mua ʻia.
Lapa loko
ʻO ka maikaʻi keleawe a me ka mānoanoa dielectric o ka papa i loko i hoʻonohonoho mua ʻia nā mea maʻamau.Eia nō naʻe, hiki ke hoʻololi ʻia i nā pono pilikino o ka papahana.
Noi o ke keleawe kalapona PCB
Hoʻohana ʻia nā PCB keleawe kaumaha i nā ʻano like ʻole, e like me nā transformers palahalaha, hoʻolaha wela, kiʻekiʻe mana hoʻopuehu, mana converters, etc. Ma PC, automotive, pūʻali koa a me ka mana mechanical, hoihoi i overwhelmingly keleawe plated papa e ulu ana.Hoʻohana nui ʻia nā papa kaapuni keleawe nui i paʻi ʻia:
1. Mea hoʻolako mana a me ka hoʻololi mana
2. Mana o na haawina
3. Nā mea hana a me nā mea hana wili
4. ʻO ka ʻoihana kaʻa
5. ʻO nā mea hana hale lā, etc
