Ibhodi yesekethe eprintiweyo (i-PCB) i-wiring idlala indima ephambili kwisekethe ephezulu, kodwa ihlala yelinye lamanyathelo okokugqibela kwinkqubo yoyilo yesekethe. Zininzi iingxaki nge-wiring ye-PCB ephezulu, kwaye uncwadi oluninzi lubhalwe kolu hloko. Eli nqaku ikakhulu lixoxa nge-wiring ye-wirit eseleyo kwimbono ebonakalayo. Eyona njongo iphambili kukunceda abasebenzisi abatsha banikele ingqalelo kwimiba emininzi eyahlukeneyo ekufuneka ithathelwe ingqalelo xa uyila indlela ephezulu yesekethe. Enye injongo kukubonelela ngezinto eziphonononga abathengi abangachukumisi i-PCB wiring okwethutyana. Ngenxa yesakhiwo esilinganiselweyo, eli nqaku alinakuxoxa ngayo yonke imiba ngokweenkcukacha, kodwa siza kuthetha ngeenxalenye eziphambili ezinesiphumo esinefuthe ekuphuculeni intsebenzo yesekethe, ixesha lokuloba, kunye nokonga ixesha lokuhlala.

Nangona eyona nto iphambili kugxilwe kuyo ikwiisekethe ezinxulumene ne-Amlifiers ePhakamileyo, iingxaki kunye neendlela ezixoxwayo apha zisetyenziswa ngokubanzi kwi-tealog esetyenziswa kakhulu. Xa i-Amlifier ye-Amlifier isebenza kwi-radio frequency ephakamileyo kakhulu (i-RF) ye-RARTE ucinga nge-frequenction, ukusebenza kwesekethe kuxhomekeke kubume bePCB. Uyilo lwesekelo lokuqhuba lula olujongeka kakuhle "kwimizobo" linokufumana kuphela ukusebenza ngokuqhelekileyo ukuba zichatshazelwa kukungakhathali ngexesha lokudinwa. Ukuqwalaselwa kwangaphambili kunye nokuqwalaselwa kweenkcukacha ezibalulekileyo kuyo yonke inkqubo ye-Wiring kuya kunceda ekuqinisekiseni ukusebenza okulindelekileyo sesekethe.

Umzobo we-Schematic

Nangona isikima esihle asinakuqinisekisa i-wiring elungileyo, i-wiring elungileyo iqala nge-schematic elungileyo. Cinga ngononophelo xa uzoba isikimu, kwaye kufuneka uqwalasele ukuhamba kwesiginali kuyo yonke isekethe. Ukuba kukho ukuhamba okuqhelekileyo nezizinzileyo ukusuka ekhohlo ukuya ngqo kwi-schematic, kuya kufuneka kubekho ukuhamba ngendlela efanayo kwi-PCB. Nika ulwazi oluluncedo olunokwenzeka kangangoko kunokwenzeka kwi-schematic. Kungenxa yokuba ngamanye amaxesha injineli yoyilo yesekethe ayikho, abathengi bayasicela ukuba sincede ekusombululeni ingxaki yesekethe, abaqulunqi, abachwephesha kunye neenjineli ezibandakanyekileyo, kuquka nathi.

Ukongeza kwisalathiso sesalathiso esiqhelekileyo, ukusetyenziswa kwamandla, kunye nokunyamezelwa kwempazamo, loluphi ulwazi ekufuneka lunikezwe kwiskiticic? Nazi ezinye zeengcebiso zokuguqula i-Schematics eqhelekileyo kwi-schematics yokuqala. Yongeza i-wavesms, ulwazi ngoomatshini malunga neqokobhe, ubude bomgca oshicilelweyo, iindawo ezingenanto; Chaza ukuba zeziphi izinto ekufuneka zibekwe kwi-PCB; Nika ulwazi lohlengahlengiso, i-ranges yexabiso lecandelo, ulwazi lokubekwa ngobushushu, imigca eprinta eprintiweyo, imigca edilileyo, izimvo, kunye nesekethe emifutshane yenkcazo yenyathelo ... (kunye nezinye).
Sukukholelwa mntu

Ukuba awuyi kuyililisile ngokwakho, qiniseka ukuba uvumela ixesha elaneleyo lokukhangela ngocoselelo uyilo lomntu. Uthintelo oluncinci luxabisa ikhulu lamaxesha amakhulu onyango ngeli xesha. Ungalindeli ukuba umntu odirikayo ukuqonde izimvo zakho. Uluvo kunye nesikhokelo sakho zezona zibalulekileyo kumanqanaba okuqala kwinkqubo yoyilo. Olunye ulwazi onokuthi lubonelele, kwaye ngakumbi ungenelele kuyo yonke inkqubo ye-Wiring, i-PCB ye-PCB enokubakho. Misela indawo yokugqitywa kwe-terical yenjineli yoyilo lwe-wiring-ikhangeleka ngokutsho kwingxelo yenkqubela phambili ye-wiring oyifunayo. Le ndlela "ye-loop evaliweyo" ithintela i-wiring kwindawo yokuhamba, ngokokunciphisa ukuncipha kwemali yokusebenza.

Imiyalelo ekufuneka inikwe injineli ye-Wiring iquka: Inkcazo emfutshane yomsebenzi wesekethe, umzobo we-scheb obonisa igalelo kunye ne-windows yendlela enobunkunkqele, i-cire yombane, i-witb ye-World, umqondiso we-Analog, umqondiso wedijithali kunye ne-RF umqondiso we-digital); Iimpawu ezifunekayo kwinoine nganye; funa ukubekwa kwezinto ezibalulekileyo; indawo echanekileyo yezinto ze-BEPAS; Le migca iprintiweyo ibalulekile; Yeyiphi imigca efuna ukulawula imigca eshicilelweyo; Yeyiphi imigca ekufuneka ihambelane nobude; ubungakanani bamacandelo; Yeyiphi imigca eprintiweyo kufuneka ibe kude (okanye kufutshane) omnye komnye; Yeyiphi imigca efuna ukuba kude (okanye kufutshane) omnye komnye; zeziphi izinto ezifuna ukuba kude (okanye zikufutshane) omnye komnye; zeziphi izinto ekufuneka zibekwe eqongeni kwi-PCB, zeziphi ezibekwe apha ngezantsi. Ungaze ukhalaze ukuba kukho ulwazi olukhulu kwabanye-elincinci kakhulu? Ngaba ininzi kakhulu? Suku.

Amava okufunda: Malunga neminyaka eli-10 eyadlulayo, ndenze iBhodi yePakethi yeMouser eNqaku-kukho izinto kumacala omabini eBhodi. Sebenzisa izikrelem ezininzi ukulungisa iBhodi kwi-Alominum yeAluminium ye-Aluminium (kuba kukho izalathisi ezinqabileyo kakhulu). Izikhonkwane ezibonelela nge-bias ukutya okuphembelele kwiBhodi. Le pi iqhagamshelwe kwi-PCB ngeengcingo ezithengisayo. Esi sisixhobo esinzima kakhulu. Ezinye izinto kwiBhodi zisetyenziselwa uvavanyo (SAT). Kodwa ndiyichaze ngokucacileyo indawo yezi zinto. Ngaba unokuqikelela ukuba kufakwe phi na la macandelo? Ngendlela, phantsi kwebhodi. Xa iinjineli zemveliso zanyanzeleka ukuba zilungelelanise isixhobo sonke kwaye zihlanganise kwakhona emva kokugqiba useto, babonakala bengonwabanga. Andenze le mpazamo kwakhona ukusukela ngoko.

Isikhundla

Njengakwi-PCB, indawo yiyo yonke into. Apho ungabeka phi isekethe kwi-PCB, apho uza kufaka khona izinto zayo zesekethe, kwaye zeziphi ezinye iisekethe ezikufuphi, zonke ezibaluleke kakhulu.

Ngokwesiqhelo, izikhundla zegalelo, ukukhutshwa, kunye nokunikezelwa kwamandla kumiselwa kwangaphambili, kodwa isiphaluka phakathi kwabo kufuneka 'sibenze ububi babo. " Kungenxa yoko le nto ukunikela ingqalelo kwii-wiriras iinkcukacha ziya kuvelisa imbuyekezo enkulu. Qala kwindawo yezinto eziphambili kwaye uqwalasele isekethe ethile kunye nePCB iphela. Ukucacisa indawo yezinto eziphambili kunye neendlela zomqondiso ukusuka ekuqaleni kunceda ukuba uyilo ludibana neenjongo zomsebenzi ezilindelekileyo zomsebenzi. Ukufumana uyilo olufanelekileyo okokuqala kunokuphucula iindleko kunye noxinzelelo-kwaye utshazeze umjikelo wophuhliso.

Amandla e -dpass

Ukudlula ukuhambisa amandla kwicala lamandla kwi-Amplifier ukwenzela ukunciphisa ingxolo kuyinto ebaluleke kakhulu kwinkqubo yoyilo lwePCB-kubandakanya i-Amplishe yesantya esiphezulu. Zimbini iindlela zokufunda eziqhelekileyo zokuphucula iisantya esiphezulu sokusebenza.

Ukuphatha isiphelo sendlela yokuhambisa amandla: Le ndlela yeyona isebenzayo kwiimeko ezininzi, usebenzisa amachaphaza amaninzi afanayo ukuya ngqo kwiPIN ye-Amplifier yoNcedo lwamandla. Ngokubanzi, amandla amabini afanayo ayanele-kodwa ukongeza amachaphaza aphezulu anokunceda isekethe.

Unxibelelwano olufanayo lwe-caprociorlel ngamaxabiso ahlukeneyo okuxhobisa lunceda ekuqinisekiseni ukuba kuphela ukutshintsha kuphela (i-AC) ekubonakaliseni kwiPIN ye-Prequenction. Oku kubaluleke kakhulu kwi-ATTNualtured ye-Ampried Amputer Amputer Amputer Amputer Amputer Anlifier Le meko ye-Capaci iya kuhlawula imbuyekezo ye-plr encitshisiweyo ye-Amplifier. Ukugcina indlela enobungozi obuphakathi kwimigangatho emininzi yeshumi le-octave kuya kunceda ukuqinisekisa ukuba ingxolo eyenzakeleyo ayinakho ukungena kwi-OP Amp. Umzobo 1 ubonakalisa izibonelelo zokusebenzisa amandla amaninzi kwi-parallel. Ngamaxesha aphantsi, amachaphaza amakhulu anikezela indlela ephantsi yomhlaba. Kodwa emva kokuba i-frequency ifikelela rhoqo, amandla e-cangocitor iya kudlala buthathaka kwaye ngokuthe ngcembe ibonakale. Kungenxa yoko le nto kubalulekile ukusebenzisa amandla amaninzi: Xa impendulo ephindaphindiweyo ye-canocite yokuqala iqala ukulahla, impendulo ephindaphindiweyo yenye i-capcitor iqala ukusebenza, ukuze ihlale iphantsi kakhulu kwi-octave yeshumi.

Qala ngokuthe ngqo kwikhonkrithi yoNcedo lwe-OP ye-AMP; I-capacitor ene-cacinoting encinci kunye nobuncinci bomzimba bufanele bubekwe kwicala elinye le-PCB njenge-APM-kwaye kufutshane kangangoko kunokwenzeka kwi-Amplifier. Isiphelo sendlela ye-capacitor kufuneka sidityaniswe ngokuthe ngqo kwindiza yomhlaba ngepine elifutshane okanye i-wire eprintiweyo. Olu nxibelelwano lungentla kufuneka lube kufutshane ne-terminal ye-Amplimie ukuze kunciphise ukuphazamiseka phakathi kwendlela ye-terminal yamandla kunye nesiphelo sendlela.

Le nkqubo kufuneka iphindwe ngabaxhasi ngexabiso elilandelayo elikhulu. Kungcono ukuqala ngexabiso eliphantsi le-0.01 μ μ μ μ μ μF (okanye enkulu) (okanye enkulu) yombane othe chu of to rivericy (ESR) kufutshane ne-IT. The 0.01 µF capacitor with a 0508 case size has very low series inductance and excellent high frequency performance.

Ukuhanjiswa kwamandla kuZwelonke: Enye indlela yoqwalaselo isebenzisa umntu omnye okanye engaphezulu kwe-Bypass exhume ngaphaya kwendawo elungileyo yokuhambisa amandla kunye nengalunganga ye-Amplimier ye-Amplifier. Le ndlela ihlala isetyenziswa xa kunzima ukuqwalasela amachaphaza amane kwisekethe. Ukungancedi kwayo kukuba ubungakanani bemeko ye-canocicit bunokonyuka kuba i-voltage yonke i-capacitor iphindaphindwe kabini kwixabiso le-voltage kwiNdlela yokuHamba enye. Ukonyusa i-voltage ifuna ukwandisa i-voltang yeso sixhobo, oko kukuthi, ukwandisa ubungakanani bezezindlu. Nangona kunjalo, le ndlela inokuphucula ukusebenza kwe-PSR kunye nokugqwetha.

Kuba isekethe nganye kunye ne-wiriring yahlukile, isimo, inani, inani kunye nexabiso lokuxhobisa kufuneka zimiselwe ngokweemfuno zesekethe leyo.
