Multilayer PCB ua maua lauiloa tele i matata eseese. I aso nei, e faigofie ona maua ni nai ituaiga o tele-layer PCBS, aofia ai 4-layer PCB, 6-layer PCB, ma isi. Ono-vaega PCBS ua avea ma tuʻufaʻatasia vaega o puʻega ofu ma isi misiona-taua fesoʻotaʻiga masini. What makes them popular? E faʻapefea ona ese mai isi ituaiga o tele-layer PCBS? O lenei pou ua fuafuaina e tali uma faʻamatalaga e te manaʻo e iloa e uiga i se 6-vaega PCB gaosi oloa.

Folasaga i le 6-layer PCB

E pei ona taʻu mai e le igoa, o le ono-vaega PCB aofia ai ono faaputuga o mea conductive. O le mea masani o le 4-layer PCB ma lua faʻaopopo faʻailoga faʻapipiʻi tuʻu i le va o vaʻalele e lua. O le 6-layer PCB faʻaputuga masani o loʻo i ai vaega e ono: e lua vaega i totonu, e lua pito i fafo ma lua vaalele i totonu – tasi mo le paoa ma le tasi mo grounding. O lenei tisaini faʻaleleia le EMI ma maua ai faʻavasega lelei mo maualalo – ma faʻavavevave saosaoa faʻailo. Lua laufanua vaega fesoasoani auala maualalo saoasaoa faailo, ae lua totonu tanu faaputuga fesoasoani ala maualuga-saoasaoa faailo.

O le ata masani o le 6-layer PCB o loʻo faʻaalia i luga; Peitai, atonu e le talafeagai mo uma talosaga. O le isi vaega o loʻo faʻamamafaina ai ni faʻavasega talafeagai o le 6-layer PCBS.

Manatu taua pe a fuafuaina le 6-layer PCBS mo eseese talosaga

Faʻaputuga faʻapipiʻi 6 vaega PCB gaosi oloa mafai ona fesoasoani ia te oe ia ausia lelei faʻatinoga aua o le a fesoasoani taofiofia EMI, faʻaaogaina ituaiga eseese o RF masini faʻapea foi ma aofia ai le tele lelei vaega pitch. Soʻo se mea sese i le lamination design e ono aʻafia ai le faʻagaioiga o le PCB. O fea e amata ai? This is how you stack properly.

L I le avea ai ma sitepu muamua i le faʻamauina o le ata, e taua le iloiloina ma faʻatonutonu le numera o le faʻavaeina, paoa sapalai ma faʻailoga vaʻai atonu e manaʻomia e le PCB.

L grounding layer o se taua vaega o soʻo se lamination aua latou te maua ai sili atu talita mo lau PCB. E le gata i lea, latou te faʻaititia le manaʻoga mo tane puipuia i fafo.

Nei o nisi faamaonia 6-vaega PCB faaputuga mamanu mo le tele o ituaiga talosaga:

L Mo vaega faʻafofoaʻo ma tamaʻi tulagavae: Afai e te fuafua e faʻaaogaina uaea faʻapipiʻi ma tamaʻi tulagavae, fa vaʻalele vaʻalele, tasi le eleele vaʻalele ma le tasi vaalele eletise mafai ona faʻapipiʻiina.

L For more dense boards that will use a wireless/analog signal mix: on this type of board, you can choose layers that look like this: signal layer/ground/power layer/ground/signal layer/ground layer. I lenei ituaiga o faʻaputuga, o le totonu ma fafo faʻailoilo faʻavae ua vavaeʻese e lua laʻasaga faʻapipiʻi eleele. Lenei faʻaputuga mamanu fesoasoani e taofi EMI fefiloi ma le totonu faailo vaega. O le faaputuga tisaini e lelei foi mo RF masini aua ac mana ma grounding maua sili decoupling.

L Mo PCB ma faʻamalama fesoʻotaʻiga: Afai e te manaʻo e fausia PCB ma tele nofouta telefoni, e sili ona lelei filifili se vaega e pei o lenei: faʻailoga vaega / mana vaega / 2 faʻailoga vaega / eleele / faʻailoga vaega. O lenei faaputuga o le a maua ai se puipuiga sili atu mo maʻa mataʻitusi. O le faʻaputuga e talafeagai mo taʻamilosaga e faʻaaogaina ai le tele o taimi faʻailoga analog poʻo le maualuga televave faʻailo. Nei faailo o le a tuʻu ese mai fafo fafo maualalo-saini faʻailo. O lenei talipupuni e faia e se vaega i totonu, lea e mafai ai foʻi ona faʻasolosolo atu faʻailo ma ala eseese poʻo fesuiaiga o saoasaoa.

L Mo laupapa o le a tufatufaina latalata i malosiaga mafuaʻaga radiation: mo lenei ituaiga o laupapa, o le grounding / faʻailoga vaega / malosiaga / faʻavaeina / faʻailoga vaega / faʻavae faaputuga o le a atoatoa. Lenei faʻaputuga mafai lelei taofiofia EMI. Lenei lamination e talafeagai foi mo laupapa faʻaaogaina i le pisapisao siosiomaga.

Faʻamanuiaga o le faʻaaogaina o le 6-layer PCBS

Faʻafetai i le ono-vaega PCB mamanu, ua avea latou ma masani masani i le tele o alualu i luma eletise matagaluega. O nei laupapa ofoina atu i lalo mea lelei e faʻafiafiaina ai i latou i masini eletise.

Laʻasaga tulagavae: O nei lolomi laupapa e laʻititi nai lo isi laupapa ona o latou tele-vaega mamanu. E aoga tele lea mo masini laʻititi.

Tulaga tuleia mamanu: E pei ona taʻua muamua, o se 6-layer PCB faaputuga mamanu manaʻomia le tele o fuafuaga. This helps reduce errors in detail, thus ensuring a high-quality build. I se faʻaopopoga, uma gaosi PCB tetele i aso nei faʻaaogaina eseese suʻesuʻega ma asiasiga metotia ina ia mautinoa le talafeagai o nei laupapa.

Malamalama mama: E maua le PCBS puʻupuʻu ile faʻaaogaina o mea mama e fesoasoani e faʻaititia ai le mamafa atoa ole PCB. E le pei o le tasi-vaega poʻo le faʻalua-vaega PCBS, ono-vaega laupapa e le manaʻomia tele fesoʻotaʻiga e fesoʻotaʻi vaega.

L Faʻaleleia le anagata: E pei ona faʻaalia i luga, o nei PCBS faʻaaogaina le tele o mea e faʻamama ai vaega i le va o taʻamilosaga ma nei vaega e fusia faʻaoga e puipuia ai mea eseese ma isi mea faʻapipiʻi muamua. E fesoasoani lea e faʻaleleia le tumau o nei PCBS.

L Lelei tele le faʻatinoina o le eletise: O nei lolomi laupapa laupapa e sili ona lelei le faʻatinoina o le eletise e mautinoa ai le maualuga o le saoasaoa ma le maualuga gafatia i vaʻaiga tisaini.
