Iingcingo ziyinxalenye ebaluleke kakhulu PCB uyilo, oluya kuchaphazela ngokuthe ngqo ukusebenza kwe-PCB. Ngexesha loyilo lwe-PCB, iinjineli ezahlukeneyo zobeko zinokuqonda kwazo ubeko lwe-PCB, kodwa zonke iinjineli zoyilo ziyavumelana ngendlela yokuphucula ukusebenza kwe-wiring, engagcini nje ngokugcina umjikelo wophuhliso lwabathengi, kodwa ikwonyusa umgangatho kunye neendleko. Oku kulandelayo kuchaza inkqubo yoyilo lwe-PCB kunye namanyathelo okuphucula ukusebenza kweentambo.

1, ukumisela inani leengcamba PCB

Ubungakanani bebhodi kunye neendlela zokucoca iintambo kufuneka zichongwe kwangoko kwinkqubo yoyilo. Ukuba uyilo lufuna ukusetyenziswa kwezinto ezixineneyo zebhola (BGA), ubuncinci benqanaba leengcingo ezifunekayo ukuhambisa ezi zinto kufuneka ziqwalaselwe. Inani lemiqolo yokufaka iintambo kunye nendlela yokubeka ngokuthe ngqo ichaphazela ngqo i-wiring kunye ne-impedance ye-wiring eshicilelweyo. Ubungakanani bebhodi banceda ukumisela isitaki kunye nobubanzi bomgca ukufezekisa uyilo olufunwayo.

2. Yila imithetho nemida

Isixhobo sokuhambisa ngokuzenzekelayo asazi ukuba senzeni. Ukufezekisa imisebenzi yokuhamba, izixhobo zokuhamba kufuneka zisebenze ngaphakathi kwemithetho efanelekileyo kunye nezithintelo. Imigca yemiqondiso eyahlukeneyo ineemfuno zentambo ezahlukeneyo, kwaye zonke iimfuno ezizodwa zemigca yesiginali zihlelwa, kwaye ukwahlula kuyilo okwahlukileyo kwahlukile. Iklasi nganye yomqondiso kufuneka ibe kwindawo ephambili. Eyona nto iphambili ephambili kukuba, umthetho ungqongqo. Imigaqo emalunga nobubanzi bokulandela umkhondo, elona nani liphezulu lokungena kwimingxunya, ukungqinelana, unxibelelwano phakathi kwemigca yesiginali, kunye nemida yomaleko inefuthe elikhulu ekusebenzeni kwezixhobo zendlela. Ukuqwalaselwa ngononophelo kweemfuno zoyilo linyathelo elibalulekileyo kwintambo eyimpumelelo.

3. Uyilo lwecandelo

Ukulungiselela iinkqubo zendibano kunye nemigaqo yokuyila (DFM) yokunyanzela imiqobo kulungelelwaniso lwamacandelo. Ukuba isebe lendibano livumela ukuba izinto zihambe, isekethe inokulungiswa ukuze isebenze ngokulula ngokulula. Imigaqo kunye nezithintelo ezichaziweyo zichaphazela uyilo loyilo.

4. Ukuthanda uyilo

Ngexesha lokuphuma kwesigaba sokuyila, izixhobo zokwenza umzila ezizenzekelayo ezidibanisa izikhonkwane zecandelo, ipini nganye yesixhobo sokukhuphuka komhlaba kufuneka ibenomngxunya omnye ukuze ibhodi ikwazi ukwenza umaleko wangaphakathi xa kufuneka unxibelelwano olongezelelweyo. Unxibelelwano, uvavanyo lwe-in-line (ICT) kunye nokuphinda wenze inkqubo yesekethe.

Ukuze isixhobo somzila esizenzekelayo sisebenze ngokukuko, esona sithuba sikhulu sombane esinokubakho kunye nomgca oshicilelweyo kufuneka usetyenziswe, ngekhefu leemitha ezingama-50 ezikhethiweyo. Sebenzisa uhlobo lwe-VIA olwandisa inani leendlela zendlela. Xa usenza uyilo lwabalandeli, jonga uvavanyo lwe-intanethi lweesekethe. Izixhobo zovavanyo zinokubiza kwaye zihlala zi-odolwa xa zilungele imveliso epheleleyo. Lihambile ixesha lokuthathela ingqalelo ukongeza ii-node ukufikelela kwi-100% yokuvavanywa.

5, i-wiring yesandla kunye nokulungiswa kwemiqondiso ephambili

Nangona eli nqaku ligxile kuhambo oluzenzekelayo, ukuhambisa ngesandla yinkqubo ebalulekileyo kuyilo lwePCB lwangoku nolwexesha elizayo. Ukuhamba ngesandla kunceda izixhobo zokuhamba ngokuzenzekelayo ukugqiba umsebenzi wokuhamba. Nokuba yeyiphi na imiqondiso ebalulekileyo, ezi zimpawu zingahanjiswa kuqala, ngesandla, okanye zisetyenziswe ngokudibeneyo nezixhobo zendlela ezizenzekelayo. Iimpawu ezibalulekileyo kufuneka zihlala ziyilwe ngononophelo ukufezekisa intsebenzo efunekayo. Kulula kubasebenzi bobunjineli ukujonga iintambo zombane emva kokugqitywa kweentambo. Le nkqubo ilula. Emva kovavanyo, ucingo lulungisiwe, kwaye eminye imiqondiso ihanjiswa ngokuzenzekelayo.

6, iintambo oluzenzekelayo

Ukuncitshiswa kweempawu ezixakekileyo kufuna ukuthathelwa ingqalelo kolawulo lweparamitha ezithile zombane ngexesha lokufaka iintambo, njengokunciphisa ukungafakwanga okusasazwayo kunye ne-EMC, kunye nokunxibelelana kweminye imiqondiso kuyafana. Bonke abathengisi be-EDA babonelela ngeendlela zokulawula ezi paramitha. Umgangatho weentambo ezizenzekelayo unokuqinisekiswa ukuya kuthi ga kwinqanaba elithile emva kokwazi iiparameter zokufaka zesixhobo se-wiring esizenzekelayo kunye nefuthe lazo kwiintambo.

7, ukubonakala kwebhodi

Uyilo lwangaphambili luhlala lujolise kwimbonakalo yebhodi, kodwa ngoku yahlukile. Ibhodi yesekethe eyilwe ngokuzenzekelayo ayisiyonto intle kunoyilo olwenziwayo, kodwa iyahlangabezana neemfuno zeempawu ze-elektroniki kwaye iqinisekisa ukuthembeka koyilo.

Ukulungiselela iinjineli zoyilo, ubuchwephesha bokungalunganga akufuneki bugwetywe ngenani leelayile kunye nesantya sodwa. Kuphela kuxa inani lezinto lilingana nesantya somqondiso kunye nezinye iimeko, indawo incinci, iindawo ezimbalwa, zehlisa iindleko. Ibhodi PCB yenzelwe kakuhle ukuqinisekisa ukusebenza kakuhle kunye nobuhle. Le yinkosi.
