PCB Ukubiyela kuyilo lwePCB kubaluleke kakhulu, indlela yokwenza iintambo ezikhawulezayo nezisebenzayo, kwaye wenze i-wiring yakho ye-PCB ijonge phezulu, kufanelekile ukuba ufunde kwaye ufunde. Kuhlelwe izinto ezi-7 ekufuneka zihlawulelwe kwi-wiring ye-PCB, yiza kujonga kwaye ugcwalise izikhewu!

Uyenza njani uyilo lwakho lwe-PCB lusebenze ngakumbi

1. Ukuqhubekeka komhlaba okuqhelekileyo kwisekethe yedijithali kunye neesekethe zeanalog

Ii-PCBS ezininzi azisekho kwimijikelezo yomsebenzi omnye (eyidijithali okanye ye-analog), kodwa ingumxube weesekethe zedijithali kunye nezeanalog. Ke ngoko, xa kusenziwa iintambo, kufuneka siqwalasele uphazamiseko phakathi kwabo, ngakumbi ukuphazamiseka kwengxolo kumgca womhlaba. Ubuntununtunu beesekethe ezihamba rhoqo zedijithali, iisekethi zeanalog, ucingo lwesiginali, imigca yesiginali-frequency ephezulu kangangoko kunokwenzeka kude nezixhobo ze-analog ezibuthathaka, emhlabeni, ukuhambisa i-PCB kwilizwe langaphandle yindawo enye kuphela, ke kufuneka ube ngaphakathi processing PCB, ukungunda unengxaki, kwaye ngaphakathi kwipleyiti ukuya digital kunye analog eneneni yahlulwe phakathi kwabo, Kuphela yi-PCB kunye nonxibelelwano lwangaphandle (njengeplagi, njl. Kukho unxibelelwano olufutshane phakathi komhlaba wedijithali kunye nomhlaba we-analog. Qaphela ukuba inye kuphela indawo yokudibanisa. Kukho ezingalunganga kwi-PCB, kuxhomekeke kuyilo lwenkqubo.

2. Umgca wesiginali ubekwe kumaleko ombane (emhlabeni)

Kwi-wiring ye-PCB ye-multilayer, kuba akukho layini igqityiweyo ishiyekile kumgca wokuyalela umqondiso, kwaye emva koko ukongeza umaleko kuya kubangela inkunkuma iya kwandisa imveliso yenani elithile lomsebenzi, iindleko zonyuke ngokufanelekileyo, ukusombulula oku kuphikisana, unokujonga iintambo zombane (emhlabeni). Ummandla wamandla kufuneka uqwalaselwe kuqala, kwaye ukwakheka okwesibini. Kungenxa yokuba kungcono ukugcina ulwakhiwo lumi kakuhle.

3. Ukulungiswa kwemilenze yokudibanisa kwindawo enkulu yokuqhuba

Kwindawo enkulu yomhlaba (umbane), imilenze yezinto eziqhelekileyo inxulumene nayo. Ukulungiswa kwemilenze yokudibanisa kufuneka kuthathelwe ingqalelo ngokubanzi. Ngokwendlela yokusebenza kombane, iiphedi zemilenze yecandelo zidityaniswe ngokupheleleyo nomphezulu wobhedu, kodwa kukho ezinye iingozi ezifihliweyo kwindibano yeewelding yamacandelo, anje ngala: (1) iwelding ifuna isifudumezi samandla esiphezulu. (2) Kulula ukubangela ukuba amalungu athengise. Ke ngoko, kuthathelwa ingqalelo ukusebenza kombane kunye nenkqubo yeemfuno, yenza iphedi yokuwelda enqamlezileyo, ebizwa ngokuba likhaka lobushushu, elaziwa njenge-Thermal, ukuze ukubanakho kwendawo ye-welding ebonakalayo ngenxa yokutshiswa kobushushu ngokwecandelo ngexesha le-welding kuncitshiswe kakhulu. Umlenze wombane (womhlaba) we-multilayer uphathwa ngokufanayo.

4. Indima yenkqubo yothungelwano kwiingcingo

Kwiinkqubo ezininzi ze-CAD, i-wiring ichongwa yinkqubo yenethiwekhi. Iigridi zixinene kakhulu, indlela inyukile, kodwa inyathelo lincinci kakhulu, umthamo wedatha yentsimi yegrafu mkhulu kakhulu, oya kuthi ngokuqinisekileyo ube neemfuno eziphezulu zokugcina indawo yezixhobo, kodwa ikwanefuthe elikhulu isantya sekhompyuter semveliso zekhompyuter. Eminye imizila ayisebenzi, njengaleyo ihlala iipads zamalungu emilenze okanye imingxunya yokufaka, ukubeka imingxunya, njl. Igridi encinci kakhulu kwaye iindlela ezimbalwa kakhulu zinempembelelo enkulu kwinqanaba lokuhambisa. Ke ngoko, kufanele ukuba kubekho inkqubo efanelekileyo yegridi yokuxhasa iintambo. Imilenze yamacandelo aqhelekileyo ayi-intshi eyi-0.1 (2.54mm) ngaphandle, ke isiseko seenkqubo zegridi zihlala zi-intshi eyi-0.1 (2.54mm) okanye ukudibanisa okuphindaphindwayo okungaphantsi kwe-intshi eyi-0.1 (umz. 0.05 intshi, 0.025 intshi, 0.02 intshi, njl. .
