Iingcingo ziyinxalenye ebaluleke kakhulu PCB uyilo, oluya kuchaphazela ngokuthe ngqo ukusebenza kwebhodi ye-PCB. Kwinkqubo yoyilo lwe-PCB, iinjineli ezahlukeneyo zobeko zinokuqonda kwazo ubeko, kodwa zonke iinjineli zoyilo ziyahambelana kwindlela yokuphucula ukusebenza kweentambo, ezingasindisi kuphela umjikelo wophuhliso weprojekthi kubathengi, kodwa ziqinisekise umgangatho kunye neendleko ukuya kwelona liphezulu. Oku kulandelayo yinkqubo ngokubanzi yoyilo kunye namanyathelo.

Indlela ukuphucula ukusebenza kweentambo kuyilo PCB

1. Chonga inani leengqimba zePCB

Ubungakanani bebhodi yesekethe kunye nenani lezintlu zewiring kufuneka zimiselwe ekuqaleni koyilo. Ukuba uyilo lufuna ukusetyenziswa kwezinto ezixineneyo zebhola (BGA), ubuncinci benqanaba leengcingo ezifunekayo kucingo lwezixhobo kufuneka ziqwalaselwe. Inani lemiqolo ye-wiring kunye ne-stack-up mode iya kuchaphazela ngokuthe ngqo ukungqinelana kunye nokuphazamiseka kwemigca eprintiweyo. Ubungakanani beplate buyanceda ukumisela ipateni yokubeka kunye nobubanzi bomgca oprintiweyo ukufezekisa isiphumo esifunekayo.

2. Yila imithetho nemida

Isixhobo sokuhambisa ngokuzenzekelayo asazi ukuba senzeni. Ukufezekisa umsebenzi we-wiring, isixhobo se-wiring kufuneka sisebenze phantsi kwemigaqo echanekileyo kunye nezithintelo. Iintambo zemiqondiso eyahlukeneyo zineemfuno ezahlukeneyo zeentambo. Iintambo zomqondiso ezineemfuno ezizodwa kufuneka zihlelwe ngokokuyilwa. Udidi ngalunye lomqondiso kufuneka lube neyona nto iphambili, kwaye okuphambili kuyeyona nto iphambili, imithetho ingqongqo. Imigaqo enxulumene nobubanzi bomgca oprintiweyo, elona nani liphezulu lemingxunya, ukufana, ukusebenzisana phakathi kwemigca yesiginali, kunye nemida yokubeka inefuthe elikhulu ekusebenzeni kwezixhobo zendlela. Ukuqwalaselwa ngononophelo kweemfuno zoyilo linyathelo elibalulekileyo kwintambo eyimpumelelo.

3. Uyilo lwecandelo

Ukuphucula inkqubo yendibano, umthetho wokuyila (DFM) ubeka izithintelo kulwakhiwo lwezinto. Ukuba isebe lendibano livumela ukuba izinto zihambe, isekethe inokulungiswa ukulungiselela ukuhambisa iintambo ngokuzenzekelayo. Imigaqo kunye nezithintelo ezichaziweyo zichaphazela uyilo loyilo.

4. Ukuthanda uyilo

Ngexesha lesigaba sokuyila fan, ukwenza isixhobo sokuhambisa ngokuzenzekelayo ukudibanisa izikhonkwane zecandelo, isikhonkwane ngasinye sombuso wentaba kufuneka sibe nomngxunya omnye ukuze ibhodi isetyenziselwe ukubopha ngaphakathi, kuvavanyo lwe-in-line (ICT ), kunye nokwenza kwakhona kwesekethe xa kufuneka unxibelelwano olongezelelweyo.

Ukunyusa ukusebenza ngokukuko kwesixhobo se-wiring esizenzekelayo, kubalulekile ukusebenzisa ubungakanani bomngxunya omkhulu kunye nelayini eprintiweyo enokwenzeka, ngekhefu le-50mil ilungile. Sebenzisa uhlobo lwendawo yokungena eyandisa inani leendlela zentambo. Uvavanyo lwe-on-line lweesekethe kufuneka luqwalaselwe xa kuyilwa fan. Izixhobo zovavanyo zinokubiza kakhulu kwaye zihlala zi-odolwa kufutshane nemveliso epheleleyo, xa kushiywe lixesha ukuba uqwalasele ukongeza iindawo ukufezekisa i-100%.

5. Ukubamba iintambo ngesandla kunye nokuqhutywa kwemiqondiso ephambili

Nangona eli phepha ligxile kwintambo ezenzekelayo, ii-wiring zesandla kwaye ziya kuba yinkqubo ebalulekileyo kuyilo lwe-PCB. Ukuhamba ngesandla kuluncedo kwizixhobo ezizenzekelayo. Nokuba yeyiphi na imiqondiso ebalulekileyo, ukufakela le miqondiso kuqala, ukufakelwa kweentambo ngesandla okanye ukudityaniswa kwezixhobo zokubiyela ezizenzekelayo. Iimpawu ezibalulekileyo zihlala zenziwe ngocoselelo ukufezekisa ukusebenza okufunwayo. Emva kokugqitywa kweentambo, i-wiring yesiginali iyajongwa ngabasebenzi bezobunjineli ezifanelekileyo, eyinkqubo elula kakhulu. Emva kokuba itsheki idlulisiwe, iingcingo zilungisiwe kwaye iintambo ezizenzekelayo zemiqondiso eseleyo ziqala.

6. Ukufakelwa iintambo ngokuzenzekelayo

Ukubiyelwa kweempawu eziphambili kufuneka ziqwalasele ukulawula ezinye iiparameter zombane ngexesha lokufaka iintambo, njengokunciphisa ukungafakwanga okusasazwayo kunye ne-EMC, kunye nokunxibelelana kweminye imiqondiso kuyafana. Bonke abathengisi be-EDA banikezela ngendlela yokulawula ezi paramitha. Umgangatho weentambo ezizenzekelayo unokuqinisekiswa ukuya kuthi ga kwinqanaba elithile ngokwazi ukuba yeyiphi iparameter yokufaka isixhobo se-wiring esizenzekelayo sinazo kunye nokuba zichaphazela njani iintambo.

7, ukubonakala kwebhodi yesekethe

Uyilo lwangaphambili luhlala lujolise kwiziphumo ezibonakalayo zebhodi yesekethe, kodwa akusekho njalo. Ibhodi yesekethe eyilwe ngokuzenzekelayo ayisiyonto intle njengokuyilwa ngesandla, kodwa inokuhlangabezana neemfuno zeempawu zombane, kwaye ukuthembeka koyilo kuqinisekisiwe.

Ukubeka iinjineli, itekhnoloji yomelele okanye hayi, akufuneki kuphela ukusuka kwinani lezendleko kunye nesantya sokugweba, kuphela kwinani lezinto, isantya somqondiso kunye nezinye iimeko ezifanayo kwimeko, ukugqiba uyilo lwendawo encinci, maleko ambalwa, amaxabiso asezantsi ebhodi ye-PCB, kunye nokuqinisekisa ukusebenza kakuhle kunye nobuhle, yile inkosi.
