I-PCB ye-Multilayer ifumene ukuthandwa okukhulu kumashishini ahlukeneyo. Namhlanje, kulula ukufumana iintlobo ezininzi zee-PCBS ezininzi, kubandakanya ne-4-layer PCB, 6-layer PCB, njalo njalo. Ii-PCBS ezingamanqwanqwa amathandathu ziye zaba yinxalenye yezinto ezinxibekayo kunye nezinye izixhobo zonxibelelwano ezibaluleke kakhulu. Yintoni ebenza badume? Zahluke njani kwezinye iindidi zeePCBS ezininzi? Esi sithuba senzelwe ukuphendula lonke ulwazi ofuna ukulwazi malunga nomvelisi wePCB we-6.

Intshayelelo kwi-PCB engama-6

Njengoko igama lisitsho, i-PCB enemigangatho emithandathu inamacandelo amathandathu ezinto ezihambisayo. Sisiseko sePCB esinohlu oluyi-4 olunamanqaku amabini ongezelelweyo abekwe phakathi kweenqwelomoya ezimbini. Isingxobo se-PCB esi-6 esiyi-layer sinezi zahlulo zintandathu zilandelayo: iileya ezimbini zangaphakathi, iileya ezimbini zangaphandle kunye neeplanethi ezimbini zangaphakathi – enye yamandla enye yeyokuseta. Olu luyilo luphucula i-EMI kwaye lubonelela ngokuhamba ngcono kweempawu ezisezantsi kunye nesantya esiphezulu. Amacwecwe omhlaba amabini anceda ukuhambisa isantya esisezantsi, ngelixa iingcwaba ezimbini zangaphakathi ezingcwatywayo zinceda indlela yesantya esiphezulu.

Uyilo oluqhelekileyo lwe-PCB engama-6 iboniswe apha ngasentla; However, it may not be suitable for all applications. Icandelo elilandelayo liqaqambisa ubumbeko olunokubakho lwee-PCBS ezi-6.

Ukuqwalaselwa okuphambili xa uyila ii-PCBS ezingama-6 zezicelo ezahlukeneyo

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. Uza kuqala ngaphi? Le yindlela obamba ngayo ngokufanelekileyo.

L Njengenyathelo lokuqala kuyilo lwe-cascading, kubalulekile ukuhlalutya kunye nokujongana nenani lomhlaba, unikezelo lwamandla kunye neeplani zomqondiso i-PCB enokuyifuna.

Iileya zokumisa umhlaba ziyinxalenye ebalulekileyo yalo naluphi na ulweliso kuba zibonelela ngokukhusela ngcono i-PCB yakho. Ngapha koko, banciphisa isidingo seetanki zokukhusela zangaphandle.

Nazi ezinye izinto ezi-6 ezingqingqwa ze-PCB eziyila uluhlu lwezicelo:

L Iipaneli ezihlangeneyo ezinendawo encinci yonyawo: Ukuba uzimisele ukufaka ucingo kwiipaneli ezinomda omncinci, iiplani ezine zomqondiso, inqwelomoya enye kunye nenqwelo moya yamandla inokufakwa.

L Kwiibhodi ezishinyeneyo eziza kusebenzisa umxube wesiginali engenazingcingo / ye-analog: kolu hlobo lwebhodi, unokukhetha umaleko obonakala ngolu hlobo: umaleko womqondiso / umhlaba / umaleko wamandla / umhlaba / umaleko wesiginali / umaleko womhlaba. Kolu hlobo lwesitaki, umaleko wangaphakathi nangaphandle wemiqolo eyahlulwe ngamanqanaba omhlaba ahlanganisiweyo. Olu luyilo lubekiweyo lunceda ukucinezela ukuxubana kwe-EMI kunye nongqameko lwangaphakathi. Uyilo lwesiteki lukwalungele izixhobo zeRF kuba amandla e-ac kunye nomhlaba zibonelela ngokudibanisa okuhle.

L Kwi-PCB eneentambo ezibuthathaka: Ukuba ufuna ukwakha i-PCB ngentambo ezininzi ezibuthathaka, kungcono ukhethe umaleko okhangeleka ngolu hlobo: umaleko womqondiso / umaleko wamandla / umaleko wesiginali emi-2 / umhlaba / umaleko wesiginali. Esi mfumba siza kubonelela ngokhuseleko olugqwesileyo kwimikhondo ebuthathaka. Isitaki silungele iisekethe ezisebenzisa imiqondiso ye-analog ephezulu okanye isantya esiphezulu sedijithali. Ezi miqondiso ziya kubekwa ecaleni kwimiqondiso engaphandle yesantya esisezantsi. Olu khuselo lwenziwa ngumaleko wangaphakathi, ovumela ukuhanjiswa kweempawu ngeendlela ezahlukeneyo okanye isantya sokutshintsha.

L Kwiibhodi eziza kufakwa kufutshane nemithombo ye-radiation eyomeleleyo: kolu hlobo lwebhodi, umhlaba / umaleko womqondiso / amandla / umhlaba / umaleko womqondiso / isitaki somhlaba siyakulunga. Esi mfumba sinokucinezela ngokufanelekileyo i-EMI. Olu lamination lukulungele iibhodi ezisetyenziswa kwindawo enengxolo.

Izibonelelo zokusebenzisa ii-PCBS ezingama-6

Enkosi kuyilo lwePCB yomaleko omathandathu, baye baba yinto eqhelekileyo kwiisekethe zombane ezihambele phambili. Ezi bhodi zibonelela ngezi zinto zilandelayo ezenza ukuba zithandwe ngabavelisi bezixhobo zombane.

Unyawo oluncinci: Ezi bhodi zishicilelweyo zincinci kunezinye iibhodi ngenxa yoyilo lwamanqwanqwa amaninzi. Oku kuluncedo ngakumbi kwizixhobo ezincinci.

Uyilo oluqhutywa ngumgangatho: Njengoko bekutshiwo ngaphambili, uyilo lwesitaki se-PCB esi-6 sifuna ucwangciso oluninzi. This helps reduce errors in detail, thus ensuring a high-quality build. Ukongeza, bonke abavelisi abakhulu bePCB namhlanje basebenzisa iindlela ezahlukeneyo zokuvavanya kunye nokuhlola ukuqinisekisa ukufaneleka kwezi bhodi.

Ukwakhiwa okuKhaphukhaphu: Ii-PCBS ezihlanganisiweyo ziyafezekiswa ngokusebenzisa izinto ezingasindi ezinceda ukunciphisa ubunzima bebonke be-PCB. Ngokungafaniyo ne-single-layer or PC-layer PCBS, iibhodi ezingqimba ezintandathu azidingi izihlanganisi ezininzi ukudibanisa izinto.

L Ukuqina okuphuculweyo: Njengoko kubonisiwe apha ngasentla, ezi PCBS zisebenzisa iindawo ezininzi zokuthintela ukombiwa phakathi kweesekethe kwaye ezi zingqimba zidityanisiwe kusetyenziswa izinto ezikhuselayo kunye nezinto zokubambelela ezahlukeneyo zangaphambili. Oku kunceda ukuphucula ukuzinza kwezi PCBS.

L Ukusebenza kombane okugqwesileyo: Ezi bhodi zesekethe ziprintwayo zinokusebenza ngokugqwesileyo kombane ukuqinisekisa isantya esiphezulu kunye namandla aphezulu kuyilo olumbeneyo.
