Lapho uklama umkhiqizo we-elekthronikhi noma isekethe, esinye sezinqumo ezibalulekile ozobhekana nazo ukukhetha uhlobo lwebhodi lesifunda eliphrintiwe (PCB) ozolisebenzisa.Izinketho ezimbili ezijwayelekile i-PCB enezinhlangothi ezimbili kanye ne-PCB enohlangothi olulodwa.Nakuba bobabili benobuhle nobubi babo, ukukhetha okufanele kungaqinisekisa ukwenziwa ngempumelelo kwephrojekthi.Kule bhulogi, sizobheka kabanzi izici zama-PCB anezinhlangothi ezimbili nama-PCB anohlangothi olulodwa ukuze sikusize wenze isinqumo unolwazi.
I-PCB enezinhlangothi ezimbili.
Ama-PCB anezinhlangothi ezimbili afaka umkhondo nezingxenye zethusi ezinhlangothini zombili zebhodi, ezixhunywe ngama-vias noma ahlanganiswe ngezimbobo.Lawa ma-vias asebenza njengama-conductive tunnels, avumela amasiginali ukuthi adlule ezingqimbeni ezihlukene ze-PCB, ayenze iminyene futhi ibe nezinto ezihlukahlukene.Lawa mabhodi avame ukusetshenziswa kumishini kagesi eyinkimbinkimbi efana nama-smartphone, i-hardware yekhompyutha, nezinhlelo zokusebenza eziminyana kakhulu.
Izinzuzo ze-PCB enezinhlangothi ezimbili.
1. Ukuminyana kwengxenye eyengeziwe: Ama-PCB anezinhlangothi ezimbili angakwazi ukuthwala izingxenye eziningi, anikeze izinga eliphezulu lokusebenza ngosayizi ohlangene.Lokhu kubalulekile lapho uklama amasistimu kagesi ayinkimbinkimbi.
2. Amakhono okufaka izintambo athuthukisiwe: Ngokulandela ithusi ezinhlangothini zombili zebhodi, abaklami banezinketho eziningi zezintambo, okunciphisa ithuba lokuphazanyiswa kwesignali kanye ne-crosstalk.Lokhu kuthuthukisa ubuqotho besignali nokusebenza kukonke.
3. Ukusebenza Kwezindleko: Naphezu kokuyinkimbinkimbi kwawo, ama-PCB anezinhlangothi ezimbili ayabiza ngenxa yokusetshenziswa kwawo okusabalele nokutholakala kwawo.Angakhiqizwa ngokuphumelelayo esikalini, okuwenza abe yinketho esebenzayo kumaphrojekthi amakhulu.
Ukungalungi kwe-PCB enezinhlangothi ezimbili
1. Ubunkimbinkimbi bomklamo: Ubunkimbinkimbi be-PCB enamacala amabili benza inqubo yokuklama ibe nzima kakhulu, edinga isofthiwe eyinkimbinkimbi nabaklami abanolwazi.Lokhu kukhuphula zonke izindleko zokuthuthukisa iphrojekthi.
2. Izinselele zokuhlanganisa: Njengoba izingxenye zikhona nhlangothi zombili, ukusoda kungaba inselele kakhulu, ikakhulukazi ezingxenyeni ze-surface mount technology (SMT).Ukunakekelwa okwengeziwe kuyadingeka ngesikhathi somhlangano ukuze kugwenywe ama-circuits amafushane namaphutha.
I-PCB yohlangothi olulodwa
Ngakolunye uhlangothi, i-PCB enohlangothi olulodwa iwuhlobo olulula lwe-PCB, enezingxenye kanye nemikhondo yethusi ekhona ohlangothini olulodwa lwebhodi.Lezi zinhlobo zama-PCB ngokuvamile zisetshenziswa ezinhlelweni ezingaxakile kangako njengamathoyizi, izibali, nezinto zikagesi ezingabizi kakhulu.
Izinzuzo ze-PCB yohlangothi olulodwa
1. Ukuklama kulula: Uma kuqhathaniswa ne-PCB enezinhlangothi ezimbili, i-PCB yohlangothi olulodwa kulula ukuyiklama.Ubulula besakhiwo busheshisa ukwenziwa kwe-prototyping futhi kunciphisa isikhathi sokuklama.
2. Yehlisa izindleko zokuthuthukisa: Ama-PCB anohlangothi olulodwa ayabiza kakhulu anezendlalelo zethusi ezimbalwa kanye nemiklamo eyenziwe lula, okuwenza alungele amaphrojekthi anebhajethi ephansi noma amaphrojekthi anezidingo ezilinganiselwe zokusebenza.
3. Inqubo yokushisela elula: Zonke izingxenye zikohlangothi olulodwa, ukushisela kuba lula, kulungele abathanda i-DIY kanye nezimfundamakhwela.Ukwengeza, ukuncishiswa kobunzima kwenza kube lula ukuxazulula izinkinga.
Ukungalungi kwe-PCB yohlangothi olulodwa
1. Izingqinamba zesikhala: Umkhawulo obalulekile wama-PCB anohlangothi olulodwa isikhala esilinganiselwe esitholakalayo sezingxenye kanye nemizila.Lokhu kunciphisa ukusetshenziswa kwazo ezinhlelweni eziyinkimbinkimbi ezidinga ukusebenza okuthuthukile noma izintambo ezibanzi.
2. Ukuphazamiseka kwesignali: I-PCB yohlangothi olulodwa ayinayo isendlalelo samandla esizimele kanye nongqimba lomhlabathi, okuzodala ukuphazamiseka kwesignali nomsindo, okuthinta ukusebenza nokuthembeka kwesekhethi.
Ukukhetha phakathi kwe-PCB enezinhlangothi ezimbili kanye ne-PCB yohlangothi olulodwa kuncike ebunzimeni nasezimfuneko zephrojekthi kagesi.Ama-PCB anohlangothi olulodwa afanele izinhlelo zokusebenza ezilula ezinomkhawulo wokusebenza, kuyilapho ama-PCB anezinhlangothi ezimbili enikeza ukuguquguquka okukhulu, ukuminyana okuphezulu kwengxenye namandla omzila athuthukisiwe kumasistimu ayinkimbinkimbi kakhulu.Cabangela izici ezifana nezindleko, izidingo zesikhala, kanye nemigomo isiyonke yephrojekthi ukuze uthole uhlobo olufanele kakhulu lwe-PCB.Khumbula, ucwaningo olufanele, ukuhlela, kanye nokubonisana nomklami we-PCB onesipiliyoni kubalulekile ekwenzeni ngempumelelo iphrojekthi yakho.
