1. Imigaqo yolungiselelo lwamacandelo
1).Kwiimeko eziqhelekileyo, onke amacandelo kufuneka ahlelwe kwindawo efanayo yesekethe eprintiweyo.Kuphela xa amacandelo umaleko ophezulu axinene kakhulu, anokuthi ezinye izixhobo ezinobude obulinganiselweyo kunye nokuveliswa kobushushu obuphantsi, njengezichasi zetshiphu, iiCapacitors zetshiphu, ii-ICs ezincamathisiweyo, njl.njl. zibekwe kumaleko asezantsi.
2).Kwisiseko sokuqinisekisa ukusebenza kombane, amacandelo kufuneka abekwe kwigridi kwaye ahlelwe ngokuhambelana nomnye okanye ngokuthe nkqo ukuze ahlambuluke kwaye ahle.Ngokubanzi, amacandelo awavumelekanga ukuba adibane;amacandelo kufuneka acwangciswe ngokudibeneyo, kwaye igalelo kunye necandelo lemveliso kufuneka ligcinwe kude kangangoko kunokwenzeka.
3).Kunokubakho umahluko omkhulu phakathi kwamacandelo athile okanye iingcingo, kwaye umgama phakathi kwabo kufuneka unyuswe ukuphepha iisekethe ezimfutshane ngengozi ngenxa yokukhutshwa kunye nokuqhekeka.
4).Izixhobo ezinombane ophezulu kufuneka zicwangciswe kwiindawo ezingenakufikeleleka ngokulula ngesandla ngexesha lokulungisa.
5).Amacandelo abekwe emphethweni webhodi, ubuncinci bebhodi e-2 ubukhulu ukusuka kumda webhodi
6).Amacandelo kufuneka asasazwe ngokulinganayo kwaye asasazwe ngokuxineneyo kwibhodi yonke.
2. Ngokomgaqo woyilo lwesalathiso somqondiso
1).Ngokuqhelekileyo ulungelelanisa indawo yeyunithi yesekethe esebenzayo nganye nganye ngokuhambelana nokuhamba komqondiso, ugxininise kwicandelo eliphambili lesekethe nganye esebenzayo, kunye noyilo olujikelezayo.
2).Ukucwangciswa kwamacandelo kufuneka kube lula ukujikeleza kwesignali, ukwenzela ukuba iimpawu zigcinwe ngendlela efanayo njengoko kunokwenzeka.Kwiimeko ezininzi, ulwalathiso lokuhamba komqondiso lucwangciswe ukusuka kwesobunxele ukuya ekunene okanye ukusuka phezulu ukuya ezantsi, kwaye amacandelo adityaniswe ngokuthe ngqo kwii-terminals ze-input kunye ne-output kufuneka zibekwe kufuphi ne-input and output connectors okanye izihlanganisi.
3. Thintela ukuphazamiseka kwe-electromagnetic 1).Kumacandelo anemimandla eyomeleleyo yemitha ye-electromagnetic kunye namalungu anovakalelo kukufakelwa kwe-electromagnetic, umgama phakathi kwawo kufuneka unyuswe okanye ukhuselwe, kwaye isalathiso sokubekwa kwecandelo kufuneka sihambelane nomnqamlezo weingcingo eziprintiweyo ezikufuphi.
2).Zama ukunqanda ukuxuba izixhobo zamandla ombane aphezulu naphantsi, kunye nezixhobo ezinemiqondiso eyomeleleyo nebuthathaka edityaniswe kunye.
3).Kumacandelo avelisa imimandla yamagnetic, efana ne-transformers, izithethi, i-inductors, njl., ingqalelo kufuneka ihlawulwe ekunciphiseni ukusika iingcingo eziprintiweyo ngemigca yamandla kazibuthe ngexesha loyilo.Izalathiso zemagnethi zamacandelo akufutshane kufuneka zibe perpendicular omnye komnye ukunciphisa ukudibanisa phakathi kwabo.
4).Khusela umthombo wokuphazamiseka, kwaye isigqubuthelo sokukhusela kufuneka sisekelwe kakuhle.
5).Kwiisekethe ezisebenza kwii-frequencies eziphezulu, impembelelo yeeparamitha zokusabalalisa phakathi kwamacandelo kufuneka ziqwalaselwe.
4. Cindezela ukuphazamiseka kwe-thermal
1).Amacandelo okufudumeza, kufuneka ahlelwe kwindawo ehambelana nokutshatyalaliswa kobushushu.Ukuba kuyimfuneko, i-radiator okanye i-fan encinci ingafakelwa ngokwahlukileyo ukunciphisa ubushushu kunye nokunciphisa impembelelo kumacandelo akufutshane.
2).Ezinye iibhloko ezidibeneyo kunye nokusetyenziswa kwamandla amakhulu, iityhubhu zamandla amakhulu okanye aphakathi, i-resistors kunye namanye amacandelo kufuneka alungiselelwe kwiindawo apho ukutshatyalaliswa kobushushu kulula, kwaye kufuneka bahlulwe kwamanye amacandelo ngomgama othile.
3).Ubushushu obunobushushu kufuneka busondele kwinto ephantsi kovavanyo kwaye lugcinwe kude nommandla wobushushu obuphezulu, ukuze ungachaphazeleki kwezinye izinto ezivelisa ubushushu kwaye zibangele ukungasebenzi kakuhle.
4).Xa ubeka amacandelo kumacala omabini, ngokuqhelekileyo akukho zixhobo zokufudumeza ezibekwe kwinqanaba elisezantsi.
5. Uyilo lwamacandelo ahlengahlengiswayo
Ukulungiswa kwamacandelo ahlengahlengiswayo njenge-potentiometers, i-capacitors eguquguqukayo, i-coil inductance adjustable okanye i-micro switches, iimfuno zesakhiwo somatshini wonke kufuneka ziqwalaselwe.Ukuba ilungelelaniswe ngaphandle komatshini, indawo yayo kufuneka iguqulelwe kwindawo yokulungelelanisa iqhosha kwipaneli ye-chassis;Ukuba ilungiswa ngaphakathi kumatshini, kufuneka ibekwe kwibhodi yesekethe eprintiweyo apho ilungiswa khona.Uyilo lwebhodi yesekethe eprintiweyo yebhodi yesekethe ye-SMT yenye yezinto eziyimfuneko kuyilo lwentaba yomphezulu.Ibhodi yesekethe ye-SMT yinkxaso yamacandelo esekethe kunye nezixhobo kwiimveliso zombane, eziqonda uxhulumaniso lombane phakathi kwamacandelo esekethe kunye nezixhobo.Ngokuphuhliswa kobuchwepheshe be-elektroniki, umthamo weebhodi ze-pcb uya usiba mncinci kwaye uncinci, kwaye ingxinano iya phezulu kwaye iphezulu, kwaye iiplanga zepcb zihlala zisanda.Ephakamileyo nangaphezulu.
