Umgangatho wobubanzi kunye nokungenisa imithetho kwi-PCB uyilo

Ukufezekisa okuhleUyilo lwe-PCBNgapha koko, ukongeza ubume be-rating ngokubanzi, imigaqo yobubanzi bomgca kunye nesithuba sibalulekile. Kungenxa yokuba ububanzi belayini kunye nokuchitha ixesha ukumisela ukusebenza kunye nokuzinza kweBhodi yeSipapathi. Ke ngoko, eli nqaku liza kubonelela ngeenkcukacha ezineenkcukacha kwiMigaqo yoyilo Jikelele yoMgangatho wePCB kunye nesithuba.

Kubalulekile ukuba uqaphele ukuba useto oluzenzekelayo lweSoftware kufuneka lubekwe ngokufanelekileyo kwaye ukhetho lomthetho wokuhlola (i-DRC) kufuneka yenziwe ngaphambi kokuba inyikima. Kucetyiswa ukuba usebenzise igridi ye-5mIl yokwaleka, kunye nobude obulinganayo 1mil gridi bunokusetwa kwimeko.

Imigaqo yobubanzi bePCB

1.Ukulalela kufuneka kuqala ukudibanaamandla emvelisoyomzi-mveliso. Qinisekisa uMvelisi weMveliso kunye noMthengi kwaye umisele amandla abo emveliso. Ukuba akukho mfuneko ikhethekileyo ibonelelwe nguMthengi, ibhekisele kwi-template yoyilo lwetemplate zobubanzi bomgca.

2.UkunyanzelaIitemplate: Ngokusekwe kwiBhodi yeBhodi ebonelelweyo kunye neemfuno zomatshini ovela kumthengi, khetha imodeli efanelekileyo yokufumana. Misela ububanzi bomgangatho ngokobubanzi obubaliweyo ngaphakathi kwimodeli yokufumana. Iinqobo zokuziphatha eziqhelekileyo eziqhelekileyo zibandakanya i-50º 5ω, 100ω, njl.njl. Qaphela ukuba umqondiso we-Ancinane we-Antenna kufuneka ujongane nesalathiso esikufuphi. Kwizitayile ze-PCB eziqhelekileyo njengesalathiso esingezantsi.

3.Akaboniswa kumzobo ongezantsi, ububanzi bomgca kufuneka buhlangabezane neemfuno zokuthwala ngoku. Ngokubanzi, ngokusekwe kumava kwaye kuthathelwa ingqalelo iimarike zokuhamba, uyilo lwamandla olubanzi lunokugqitywa kwezi zikhokelo zilandelayo: kubushushu obuza kububanzi be-10OZ, ububanzi be-1OZ bungakwazi ukujongana ne-1A; I-0.5Oz yobhedu, ububanzi be-40mm ye-40mm bungasingathanga i-1A ye-1A.

4. Ngeenjongo zoyilo ngokubanzi, ububanzi bomgca kufuneka kukhethelwe ukuba zilawulwe ngaphezulu kwe-4mIl, enokuhlangabezana negalelo lemveliso uninziAbavelisi bePCB. Ngemichalo apho ulawulo lokujongwa aluyimfuneko (ubukhulu becala 2-Windows), ukuyila ububanzi bomgca ongentla kwe-8ml kunceda ukunciphisa iindleko zokwenza imveliso.

5. Cinga ngeubukhulu becalaUkuseta umaleko ohambelana nokuhamba. Thatha umzekelo we-2oz umzekelo, zama ukuyila ububanzi belayini ngaphezulu kwe-6mil. Umthungo ubhedu, ubukhulu becala ububanzi bomgca. Cela iimfuno zemveliso zomzi-mveliso wobutyebi bobhedu olungeyongobhedu olungekamgangatho.

I-6. Kwimililo ye-BGA ene-0.5mm kunye ne-0.55mm imijelo, ububanzi bomgca we-3.5mlil bomgca unokusetyenziswa kwiindawo ezithile (inokulawulwa yimithetho yoyilo).

7. Ibhodi ye-HDIUyilo lunokusebenzisa ububanzi bomgca we-3MIL. Ngeeyilo kunye nobobubanzi belayini ngaphantsi kwe-3MIL, kuyimfuneko ukuqinisekisa ukuba amandla omzi-mveliso kunye nomthengi, njengoko abathengi be-2mlil banakho ukulawula imithetho yoyilo). I-Chinanels inyusa iindleko zemveliso kwaye zandise umjikelo wemveliso.

I-8. Iimpawu ze-analog (ezinjengeempawu zevidiyo kunye nevidiyo) kufuneka zenziwe ngemigca emitsha, ngokwesiqhelo zijikeleze i-15mil. Ukuba indawo inomda, ububanzi belayini kufuneka bulawulwe ngaphezulu kwe-8MIl.

I-9. Iimpawu zeRF kufuneka zikhutshelwe ngemigca emitsha, ngokubhekisele kwizibonda ezikufuphi kunye nokunyanzeliswa kwe-50ω. Iimpawu ze-RF kufuneka zigqitywe kwi-ofisi yangaphandle, zithintele ii-birs zangaphakathi kwaye zinciphise ukusetyenziswa kwe-vias okanye i-fallter. Iimpawu ze-RF kufuneka zijikelezwe yindiza esemhlabeni, kunye nesalathiso sereferensi ngokukhethekileyo ukuba yi-gndreper yobhedu.

IMithetho ye-PCB ye-PCB

1. I-wiring kufuneka iqale ihlangabezane nomsebenzi wokulungisa umzi-mveliso, kwaye indawo yokubeka ilayini kufuneka ifezekise ubuchule bomzi-mveliso, ilawulwa ngokubanzi nge-4 Mil okanye ngaphezulu. Nge-Bga uyilo nge-0.5mm okanye i-0.65mm spapting, i-spacling ye-3.5 ye-Mil ingasetyenziswa kwezinye iindawo. Uyilo lwe-HDI lunokukhetha indawo yokuma kwe-3 Mil. Uyilo olungaphantsi kwe-3 Mil kufuneka luqinisekise ukuba amandla omzi-mveliso onemveliso kunye nomthengi. Abanye abavelisi banemveliso yokufumana i-2 Mil (ilawulwa kwiindawo zoyilo oluthile).

2. Ngaphambi kokuba uyilise umthetho wokuvala umgca, qwalasela ubukhulu bobhedu loyilo. Kwi-overper eyi-1 ye-overper izama ukugcina umgama we-4 Mil okanye ngaphezulu, kunye ne-2 yobhedu, zama ukugcina umgama we-6 mil okanye ngaphezulu.

3. Uyilo lomgama olwahlukileyo lweziqwengana zomqondiso olwahlukileyo kufuneka zisetwe ngokweemfuno zeMedi

4. I-wiring kufuneka igcinwe kude kwibhodi yebhodi kwaye uzame ukuqinisekisa ukuba i-HARCE yeBhola inokuba nayo umhlaba (GNN). Gcina umgama phakathi kwemiqondiso kunye nemiphetho yeBhodi ngaphezulu kwe-40 Mil.

I-5. Umqondiso woMandla kufuneka ube nomgama ubuncinci we-10 mil kwi-GND. Umgama phakathi kwamandla kunye namandla eenqwelomoya kufuneka ubuncinci ube yi-10 Mil. Kwezinye ii-ics (ezinjenge-BGAS) ngezithuba ezincinci, umgama unokuhlengahlengiswa ngokufanelekileyo ube yi-6 mil (ilawulwa kwiindawo zoyilo oluthile).

6.Umqondiso ofana neewotshi, umahluko, kunye nemiqondiso ye-alog kufuneka ibe nomgama oziimitha ezintathu ububanzi (3w) okanye ujikelezwe ngumhlaba (i-GNND). Umgama phakathi kwemigca kufuneka ugcinwe ngamaxesha ama-3 umgca ububanzi ukunciphisa i-crossulk. Ukuba umgama phakathi kwamaziko emigca emibini ungaphantsi kwamaxesha ama-3 ububanzi bomgca, unokugcina iipesenti ezingama-70 zendawo yombane phakathi kwemigca, eyaziwa ngokuba yi-3W umgaqo.

I-7.Adyadsment yezazisi kufuneka sikuphephe ukuntywila ngokuhambelana. Isikhokelo sokuhambisa kufuneka senze isakhiwo se-orthogonal sokunciphisa i-intertortalk engafunekiyo.

8. Xa ujikeleza umphezulu wengqimba, gcina umgama ongu-1mm ukusuka kwimingxunya yokuphakamisa ukhusela imijikelezo emifutshane okanye ukuqhekezwa kwelayini ngenxa yoxinzelelo lofakelo. Indawo ejikeleze imingxunya ye-screw kufuneka igcinwe icacile.

9. Xa wahlulahlula izabelo zamandla, kuphephe izahlulelo ezinamandla kakhulu. Kwindiza enye yamandla, zama ukungabi nazimpawu ezingaphezulu kwe-5, ngokukhethekileyo kwimiqondiso emi-3, ukuqinisekisa ukuthwala okwangoku kwaye kunqande umngcipheko wezahlulo

10. Izahlulo ze-rawer yezahlulo kufuneka zigcinwe rhoqo, ngaphandle kozahlulo ezide okanye ezinxunguphele, ukuthintela iimeko apho zinkulu kwaye ziphakathi zincinci kwaye eziphakathi zincinci kwaye eziphakathi zincinci kwaye eziphakathi zincinci kwaye umphezulu omncinci. Umthamo wokuphefumla okhoyo kufuneka ubalwe ngokusekwe kububanzi obuncinci bendiza yenqwelomoya.
