Kule mihla, anda ngakumbi i-compact yeemveliso ze-elektroniki ifuna uyilo oluhle kakhulu lweebhodi zesekethe eziprintwayo. Nangona kunjalo, ukubekwa kwebala kuphakamisa imiba emitsha enxulumene nale njongo yoyilo. Enye yeengxaki kukufumana indawo yokwakha ephezulu yeprojekthi.

Njengakwisekethe esenziwe ngaphezulu nangakumbi esishicilelweyo esishicilelweyo senziwe ngamaqhekeza amaninzi, i-PCBS ye-PCBs ibaluleke ngokukhethekileyo.

Uyilo oluhle lwe-PCB lufanelekile ukunciphisa i-radiation ye-pcb lops kunye nesekethe ezinxulumene noko. Ngokuchasene noko, ukuqokelelwa okungalunganga kunokunyusa kakhulu i-radiation, eyenzakalisayo kwindawo yokhuseleko.
Yintoni i-PCB stackup?
Phambi kokuba kuyilo lokugqibela lugqityiwe, i-PCB STACKUS I-CUSTER HORTATORE kunye nobhedu lwePCB. Ukuphuhliswa kokusetyenziswa okusebenzayo yinkqubo entsonkothileyo. I-PCB inxibelelanisa amandla kunye nemiqondiso phakathi kwezixhobo zomzimba, kunye nokuhonjwa ngokuchanekileyo kweempawu zebhodi yesekethe kuchaphazela ngqo umsebenzi wayo.

Kutheni le nto kufuneka senze i-PCB?
Ukuphuhliswa kwe-PCB Stackip kubalulekile ekuyileni iibhodi zesekethe ezifanelekileyo. I-PCB Stackip ineengenelo ezininzi, kuba ulwakhiwo lweMininzi lunokuphucula ukusasazwa kwamandla, khusela ukuphazamiseka kwe-electromagnetic, umda uphazamiseko lwendlela, kunye nokuxhasa usulelo oluphezulu.

Nangona eyona njongo iphambili yokufaka i-stagen kukubeka imijikelezo emininzi ye-elektroniki kwiBhodi enye ngokusebenzisa inani elininzi, isakhiwo esibekiweyo see-PCBs sikwanika ezinye izibonelelo ezibalulekileyo. La manyathelo abandakanya ukunciphisa ukungathathi ntweni kweebhodi zebhokisi ukuya kwingxolo yangaphandle kunye nokunciphisa iingxaki ze-crostalk kunye neengxaki zokunyanzela kwiinkqubo ezihamba ngesantya esiphezulu.

I-stackup elungileyo ye-PCB inokunceda ukuqinisekisa iindleko ezisezantsi zemveliso. Ngokwandisa ukusebenza kunye nokuphucula ubume be-Elecromagnetic kuyo yonke iprojekthi, i-PCB i-PCB i-PCB inokugcina ixesha kunye nemali.

Ukuthatha amanyathelo okhuseleko kunye nemithetho yoyilo lwe-PCB
● Inani leendawo
Ukufakwa ngokulula kunokubandakanya i-PCBS ye-Winder ezine, ngelixa iibhodi ezintsonkothileyo zifuna ukwahlula-hlukeneyo. Nangona inani elikhulu kakhulu, inani eliphezulu leendawo zivumela abaqulunqi ukuba babe nendawo yokubeka okungakumbi ngaphandle kokwandisa umngcipheko wokudibana nezisombululo ezingenakwenzeka.

Ngokubanzi, iingqimba ezinesibhozo okanye ezingaphezulu ziyafuneka ukuba zifumane ulungelelwaniso olulungileyo kunye nesithuba sokwandisa ukusebenza. Sebenzisa iindiza ezisemgangathweni kunye neeBhodi zamandla kwiBhodi yeZilayidi zeZilayidi nazo kunokunciphisa imitha.

● Ulungelelwaniso
Ilungiselelo lolawulo lobhedu kunye ne-submer yamanzi efakelayo esebenza isekethe isebenza ngaphezulu kwe-PCB ngaphezulu. Ukuthintela i-PCB eMfihlayo, kuyimfuneko ukwenza icandelo lomnqamlezo leBhodi kwaye lilinganiselwe xa ilele iileyiki. Umzekelo, kwiBhodi ye-Wieri esibhozo, ubukhulu becala kunye neyesibini kunye neendlela zesixhenxe kufuneka zifanane nokufezekisa eyona nqanaba ilunge ngakumbi.

Umaleko womqondiso kufuneka uhlala ecaleni kweplanethi, ngelixa inqwelomoya kunye neplanethi esemgangathweni idityaniswa ngokudibeneyo. Kungcono ukusebenzisa iinqwelomoya ezininzi, kuba zihlala zinciphisa i-radiation kunye nenqanaba eliphantsi eliphantsi.

● Uhlobo lwezinto ezibonakalayo
I-thermal, yoomatshini, kunye nepropathi yombane yecandelo ngalinye nendlela abanxibelelana ngayo zibaluleke kakhulu ekukhetheni izixhobo ze-PCB.

Ibhodi yesekethe idla ngokudityaniswa kweglasi ye-fiber yefibre enamandla, ebonelela ngobungqingqwa kunye nobungqola be-PCB. Ezinye iiPCB eziguquguqukayo zinokwenziwa ngamadlala amaqondo obushushu aphezulu.

I-subter yomphezulu yi-foil emdaka eyenziwe nge-foil yobhedu iqhotyoshelwe kwiBhodi. Ubhedu lukhona kuwo omabini amacala ePCB ephindwe kabini, kwaye ubukhulu bobhedu lwahluka ngokwenani lezinto ze-PCB.

Gubungela phezulu kwi-foil yobhedu ye-foil enemaski yejoni ukwenza ubhedu lobhedu lunxibelelana nezinye izinyithi. Esi sixhobo sibalulekile ukuze sincede abasebenzisi baphephe ukurhweba indawo echanekileyo yee-jumper iingcingo.

Umaleko wokuprinta usetyenziswa kwimaski yeThrinta ukongeza iisimboli, amanani kunye neeleta ukulungiselela i-Consch kwaye uvumele abantu ukuba baqonde ngcono iBhodi yeSiphako.

● Chonga i-wiring kunye nemingxunya
Abaqulunqi beendlela zendlela ifanele ukuba imiqondiso yesantya esiphezulu kwi-suber ephakathi phakathi kweengcambo. Oku kuvumela iplani yomhlaba ukuba ibonelele ngokukhuselekileyo equlethe i-rada ikhutshelwe umkhondo kwisantya esiphezulu.

Ukubekwa kwenqanaba lomqondiso kufutshane nenqanaba leplanethi kuvumela ukubuya kwangoku ukuze kuhambe kwindiza ekufuphi, ngaloo ndlela kuncitshiswa i-intengo yokubuya. Akukho candlatity yaneleyo phakathi kwamandla akwiindlela ezikufuphi nomhlaba ukubonelela nge-decoupling ngaphantsi kwe-500 MHZ usebenzisa iindlela zokwakha ezemigangatho.

● Ukuhamba phakathi kweengxwaba
Ngenxa yokuncitshiswa okuncitshisiweyo, ukudibanisa okuqinileyo phakathi komqondiso kunye nenqwelomoya yangoku ibalulekile. Amandla kunye neenqwelomoya zomhlaba kufuneka zidityaniswe ngokuqinileyo kunye.

Imiqondiso yesayini kufuneka ihlale ikufuphi nomnye nokuba zikhona kwiinqwelomoya ezikufuphi. Ukudibana ngokuqinileyo kunye nesithuba phakathi kweengcambu kubalulekile kwimiqondiso engaphazanyiswa kunye nokusebenza ngokubanzi.

ukushwankathela
Zininzi ii-PCB zeBhodi yeBhodi ye-PCB ye-Mulb ye-PCB kwitekhnoloji yokufaka itekhnoloji. Xa abandakanyekayo abaninzi babandakanyekile, indlela enemilinganiselo emithathu ethatha isakhiwo sangaphakathi kunye nobume bomphezulu kufuneka budityaniswe. Ngezintya eziphezulu zokunxiba zesekethe yale mihla, uyilo lwe-PCB lwe-PCB lwe-PCB kufuneka lwenziwe ukuphucula amandla okusasaza kunye nokuphazamiseka. I-PCB eyilelwe kakuhle inokunciphisa ukuhanjiswa kwesibonakaliso, inzala, ukuhambisa amandla, kunye nokuthenjwa kwexesha elide.
