Uvakalelo lwezixhobo ze-elektroniki luya phezulu nangaphezulu, nto leyo efuna ukuba isixhobo sibe namandla okumelana nokuphazamiseka. Ngoko ke, PCB uyilo lube nzima ngakumbi. Indlela yokuphucula isakhono sokuchasana nokuphazamiseka kwe-PCB iye yaba ngomnye wemiba ephambili ekufuneka iinjineli ezininzi ziqwalasele. Eli nqaku lizakwazisa iingcebiso zokunciphisa ingxolo kunye nokuphazamiseka kombane kuyilo lwePCB.

Ezi zilandelayo ziingcebiso ezingama-24 zokunciphisa ingxolo kunye nokuphazamiseka kombane kuyilo lwePCB, olushwankathelwa emva kweminyaka yoyilo:

(1) Iitshiphusi ezinesantya esiphantsi zinokusetyenziswa endaweni yeetshiphusi ezinesantya esiphezulu. Iitshiphusi ezinesantya esiphezulu zisetyenziswa kwiindawo eziphambili.

(2) I-resistor inokudityaniswa kuthotho ukunciphisa izinga lokutsiba kwimida ephezulu nasezantsi yesekethe yolawulo.

(3) Zama ukubonelela ngolunye uhlobo lokudambisa ukuhanjiswa, njl.

(4) Sebenzisa iwotshi yamaxesha esezantsi ehlangabezana neemfuno zenkqubo.

(5) Ijenereyitha yewotshi isondele kangangoko kwisixhobo esisebenzisa iwotshi. Igobolondo ye-quartz crystal oscillator kufuneka ibekwe phantsi.

(6) Vala indawo yewotshi ngocingo oluphantsi kwaye ugcine ucingo lwewotshi lufutshane kangangoko.

(8) Isiphelo esingenamsebenzi se-MCD kufuneka sidityaniswe phezulu, okanye sibekwe phantsi, okanye sichazwe njengesiphelo semveliso, kwaye isiphelo sesiphaluka esidibeneyo esimele sidityaniswe kumhlaba wokubonelela ngombane kufuneka sidityaniswe, kwaye akufanele sishiywe sidada. .

(9) Musa ukushiya i-terminal yegalelo yesekethe yesango engasetyenziswayo. I-terminal yegalelo elilungileyo le-terminal ye-amplifier engasetyenziswanga isekelwe, kwaye i-terminal igalelo elibi liqhagamshelwe kwi-terminal ephumayo.

(10) Kwiibhodi eziprintiweyo, zama ukusebenzisa imigca engama-45 endaweni yemigca engama-90 ukunciphisa ukukhutshwa kwangaphandle kunye nokudibanisa izibonakaliso ze-high-frequency.

(11) Ibhodi eprintiweyo yahlulahlulwe ngokokuphindaphinda kunye neempawu zokutshintsha kwangoku, kwaye amacandelo engxolo kunye namacandelo angeyongxolo kufuneka abe kude.

(12) Sebenzisa umbane wenqaku elinye kunye nesiseko sendawo enye yeepaneli ezingatshatanga kunye nezimbini. Umgca wamandla kunye nomgca womhlaba kufuneka ube mkhulu kangangoko. Ukuba uqoqosho lufikeleleke, sebenzisa ibhodi ye-multilayer ukunciphisa i-capacitive inductance yokunikezelwa kwamandla kunye nomhlaba.

(13) Iwashi, ibhasi, kunye neempawu zokukhetha itshiphu kufuneka zibe kude nemigca ye-I/O kunye nezihlanganisi.

(14) Umgca wokufakwa kwamandla ombane we-analog kunye netheminali yombane wereferensi kufuneka ube kude kangangoko kunokwenzeka kumgca wesignali yesekethe yedijithali, ngakumbi iwotshi.

(15) Kwizixhobo ze-A/D, inxalenye yedijithali kunye nenxalenye ye-analog inokukhetha ukumanyana kunokuwela.

(16) Umgca wewashi nge-perpendicular kumgca we-I / O unokuphazamiseka okuncinci kunomgca we-I / O ohambelanayo, kunye nezikhonkwane zecandelo lewashi zikude kwi-cable ye-I / O.

(17) Izikhonkwane zecandelo kufuneka zibe zifutshane kangangoko kunokwenzeka, kwaye i-decoupling capacitor pins kufuneka ibe mfutshane kangangoko.

(18) Umgca wesitshixo ufanele ube ngqindilili kangangoko kunokwenzeka, yaye umhlaba okhuselayo ufanele wongezwe kumacala omabini. Umgca wesantya esiphezulu kufuneka ube mfutshane kwaye uqonde.

(19) Imigca echaphazeleka kwingxolo ayifanele ihambelane nemigca yangoku ephezulu, enesantya esiphezulu.

(20) Musa ukuhambisa iingcingo phantsi kwekristale yequartz naphantsi kwezixhobo ezingeva ingxolo.

(21) Kwiisekethe zesignali ezibuthathaka, musa ukwenza iilophu zangoku malunga neesekethe eziphantsi-frequency.

(22) Musa ukwenza i-loop kumqondiso. Ukuba ayinakuphepheka, yenza indawo yelophu ibencinci kangangoko.

(23) I-capacitor enye yokuqhawula kwisekethe edibeneyo. I-capacitor encinci ye-high-frequency bypass capacitor kufuneka yongezwe kwi-electrolytic capacitor nganye.

(24) Sebenzisa i-tantalum capacitors enkulu okanye i-juku capacitors endaweni ye-electrolytic capacitors ukuhlawula kunye nokukhupha i-capacitors yokugcina amandla. Xa usebenzisa i-tubular capacitors, ityala kufuneka libe phantsi.
