Multilayer pcb akawana mukurumbira mukuru mumaindasitiri akasiyana siyana. Nhasi, zviri nyore kuwana akati wandei emhando dzakasiyana-siyana PCBS, kusanganisira 4-rukoko pcb, 6-rukoko pcb, zvichingodaro. Matanhatu-masenduru PCBS ave chikamu chakakosha chemakomputi ekupfeka uye mamwe mamishini-akakosha ekutaurirana maturusi. Chii chinoita kuti vafarirwe? Vakasiyana sei kubva kune mamwe marudzi ePCBS mazhinji? Iyi posvo yakagadzirirwa kupindura ruzivo rwese iwe rwaunoda kuziva nezve 6-rukoko pcb inogadzira.

Nhanganyaya ku6-layer PCB

Sezvo zita rinoreva, matanhatu-rukoko pcb ine nhanhatu nhanhatu conductive zvinhu. Chaizvoizvo i4-rukoko pcb ine maviri ekuwedzera mamaki mamaki akaiswa pakati pendege mbiri. Yakajairika 6-rukoko pcb stack ine anotevera matanhatu akaturikidzana: maviri emukati akaturikidzana, maviri ekunze akaturikidzana uye maviri emukati ndege – imwe yesimba uye imwe yevhu. Iyi dhizaini inovandudza EMI uye inopa zvirinani nzira yekudzika – uye yakakwira-inomhanya masaini. Mavara maviri epamusoro anobatsira nzira yakaderera-yekumhanya masaini, nepo maviri emukati akavigwa akaturikidzana anobatsira nzira yekumhanyisa-mamasaini.

Iyo yakajairika dhizaini ye6-layer PCB inoratidzwa pamusoro; However, it may not be suitable for all applications. Chikamu chinotevera chinoratidzira zvimwe zvingangoitika zve6-layer PCBS.

Kukoshesa kutarisisa paunenge uchigadzira 6-layer PCBS yezvishandiso zvakasiyana

Properly stacked 6 layers PCB manufacturers can help you achieve better performance because it will help suppress EMI, use various types of RF devices as well as include several fine-pitch components. Any errors in the lamination design can seriously affect PCB performance. Kutangira papi? Aya ndiwo marongedzero aunoita nemazvo.

L sedanho rekutanga mukubvaruka dhizaini, zvakakosha kuti uongorore uye kugadzirisa huwandu hwenzvimbo dzekuisa pasi, magetsi uye ndege dzemasaini iyo PCB ingangoda.

L yekumisikidza zvidimbu chikamu chakakosha chechero lamination nekuti inopa dziviriro iri nani kune yako PCB. Uyezve, ivo vanodzikisira kudiwa kwekunze kunodzivirira matangi.

Heano mamwe maratidziro matanhatu-masenduru pcb makaki dhizaini emhando dzakasiyana dzekushandisa:

L Yecompact mapaneru ane diki tsoka

L Kune mamwe mabhodhi akaomarara anozoshandisa musanganiswa weasina waya / analogogo: pane iyi mhando yebhodhi, unogona kusarudza zvidimbu zvinotaridzika seizvi: chiratidzo cheyadhi / pasi / simba rukoko / pasi / chiratidzo denderedzwa / pasi rukoko. Mune irudzi urwu rwekututira, zvidimbu zvemukati nekunze zvinoparadzaniswa nezvikamu zviviri zvevhu zvakaputirwa. Iyi dhizaini dhizaini inobatsira kudzvinyirira EMI kusanganisa neyemukati chiratidzo cheturu. Iyo stack dhizaini zvakare yakanaka kune maRF zvishandiso nekuti ac simba uye pasi zvinopa kwazvo decoupling.

L YePCB ine wiring inonamira: Kana iwe uchida kuvaka PCB ine yakawanda wiring tambo, zvakanakisa kusarudza dura rinotaridzika seiyi: chiratidzo cheyadhi / simba rondedzero / 2 chiratidzo cheyadhi / pasi / chiratidzo cheyadhi. Iyi stack inopa dziviriro yakanakisa kune yakasarudzika matanho. Iyo stack inokodzera kumatunhu ayo anoshandisa yakakwira frequency maanalog zviratidzo kana akakurumidza kumhanya madhijitari. Zviratidzo izvi zvichave zvakasarudzika kubva kune ekunze emasaini-ekumhanyisa masaini. Uku kudzivirirwa kunoitwa neyemukati layer, iyo zvakare inobvumidza kuendesa kwemasaini nema frequency akasiyana kana kushandura kumhanya.

L Yemabhodhi anozoiswa padhuze neakasimba radiation masosi: erudzi urwu rwebhodhi, iyo grounding / signal layer / simba / grounding / signal layer / grounding stack ichave yakakwana. Iyi stack inogona kudzvinyirira EMI. Iyi lamination inokodzerawo mabhodhi anoshandiswa munzvimbo dzine ruzha.

Benefits of using 6-layer PCBS

Kutenda kune matanhatu-rukoko pcb dhizaini, ivo vakave akajairwa maficha mune akati wandei epamberi emagetsi macircuit. Aya mabhodhi anopa zvinotevera zvinotevera izvo zvinoita kuti vazive nevakagadziri vemagetsi.

Tsoka diki: Aya mabhodhi akadhindwa madiki pane mamwe mabhodhi nekuda kweyakagadzirwa-yakawanda dhizaini. Izvi zvinonyanya kubatsira kune michina midiki.

Dhizaini dhizaini dhizaini: Sezvambotaurwa pakutanga, 6-rara pcb stack dhizaini inoda yakawanda kuronga. This helps reduce errors in detail, thus ensuring a high-quality build. Uye zvakare, vese vakuru vePCB vagadziri nhasi vanoshandisa nzira dzakasiyana dzekuyedza uye dzekuongorora kuona kukodzera kwemabhodhi aya.

Chiedza chisina kuremerwa: Compact PCBS inoitwa nekushandisa zvisingaremi zvinhu zvinobatsira kudzikisa huremu hwese hwePCB. Kusiyana neka-single-layer kana yakapetwa kaviri PCBS, matanhatu-maseru emabhodhi haadi akawanda macomputer ekubatanidza zvikamu.

L Kuvandudzika kusimba: Sezvinoratidzwa pamusoro, aya maPCBS anoshandisa akawanda ekudzivirira materu pakati pemaseketi uye aya matanda akasungirirwa achishandisa zvinhu zvekudzivirira uye akasiyana prereg adhesives. This helps improve the durability of these PCBS.

L Kwakanaka mashandiro emagetsi: Aya anodhindwa wedunhu mabhodhi ane akanakisa emagetsi mashandiro kuverengera kumhanya uye kwakakwira kugona mune compact magadzirirwo.
