Ibhodi le-PCB (i-Printedcircuitboard) liyindikimba yokusekela izingxenye ze-elekthronikhi kanye nomhlinzeki wokuxhumanisa phakathi kwezingxenye ze-elekthronikhi nezingxenye zikagesi. Cishe liyingqalasizinda yawo wonke amadivayisi ahlakaniphile. Ngaphezu kwemisebenzi eyisisekelo yokulungisa izingxenye ezincane ze-elekthronikhi ezahlukahlukene, umsebenzi obaluleke kakhulu ukuhlinzeka ngokuxhumana kwezingxenye ze-elekthronikhi ezingenhla.
Yiziphi izingxenye zebhodi le-PCB?
Ibhodi lesifunda le-PCB lakhiwe kakhulu ngephedi yokushisela, imbobo edlulayo, imbobo yokufaka, ucingo, izingxenye, izixhumi, ukugcwalisa, umngcele kagesi nokunye.
(1) Iphedi: imbobo yensimbi esetshenziselwa izikhonkwane zokushisela zezingxenye.
(2) Imigodi edlulayo: kunensimbi edlulayo emigodini kanye nengeyona insimbi edlulayo emigodini, lapho insimbi edlulayo emigodini isetshenziswa ukuxhuma izikhonkwane zezingxenye phakathi kwesendlalelo ngasinye.
(3) Imbobo yokufaka: esetshenziselwa ukulungisa ibhodi yesekethe.
(4) I-conductor: ifilimu yethusi yenethiwekhi kagesi esetshenziswa ukuxhuma izikhonkwane zezingxenye.
(5) Izixhumi: izingxenye ezisetshenziselwa ukuxhuma amabhodi wesekethe.
(6) Ukugcwalisa: ukufakwa kwethusi kwinethiwekhi yocingo lomhlabathi kunganciphisa ngempumelelo ukuvimba.
(7) Umngcele kagesi: osetshenziselwa ukunquma usayizi webhodi lesifunda, izingxenye zebhodi azikwazi ukudlula umngcele.
Ibhodi lesifunda le-PCB ngokwesakhiwo lingahlukaniswa libe yiphaneli elilodwa le-PCB, iphaneli eliphindwe kabili le-PCB, ibhodi le-PCB elinezingqimba eziningi; Ibhodi elivamile elinezingqimba eziningi linezingqimba ezine, ibhodi elinezingqimba eziyisithupha, ibhodi le-PCB elinezingqimba eziningi eziyinkimbinkimbi lingafinyelela izingqimba ezingaphezu kweshumi.
Uma izingqimba eziningi zamabhodi e-PCB, ukusebenza kukagesi kuzinze futhi kuthembekile, futhi izindleko ziphakeme. Umehluko wezindleko zamaphaneli angawodwa namabili awumkhulu. Uma kungekho mfuneko ekhethekile, zonke izimboni zizokhetha amaphaneli aphindwe kabili. Phela, ukusebenza kanye nokuqina kwephaneli eliphindwe kabili kungcono kunokwephaneli elilodwa.
Ebhodini le-PCB elinezingqimba eziningi, manje imboni iyibhodi elisetshenziswa kakhulu noma elinezingqimba ezine, imboni ye-elekthronikhi yabathengi enebhodi le-pcb elisezingeni eliphezulu ingaphezulu. Nakuba amaphaneli anezingqimba eziningi enezinzuzo eziningi kunezingqimba ezimbili ekusebenzeni, ukuzinza, umsindo nezinye izici, amabhizinisi amaningi nonjiniyela basathanda amaphaneli amabili ukuze kucatshangelwe izindleko.
Njengoba amadivayisi ahlakaniphile eba yinkimbinkimbi ngokwengeziwe, kudingeka izesekeli ezengeziwe, okuholela kumasekethe amaningi aqinile kanye nezesekeli ku-PCB. Ngesikhathi esifanayo, izidingo zekhwalithi zezixhumi zebhodi le-PCB zamanje eziphakeme nazo ziyathuthukiswa. Ibhodi le-PCB elincane alikwazi nje ukunciphisa izindleko, kodwa futhi lingenza lula ukwakheka kwebhodi le-PCB, ukuze ukulahlekelwa kwesignali yokudlulisa isekethe kube kuncane.
Isixhumi sebhodi le-PCB elinamanzi aphezulu silingana ne-knuckle kuphela, kanti umqhubi wokuxhumana ufakwe isiliva ngethusi elibomvu, okuthuthukisa kakhulu ukusebenza kokuthwala kwamandla kwesixhumi. Ngisho nosayizi omncane ungaba nokuthwala kwamandla aphezulu, okuqinisekisa ukusebenza kahle kwesekethe, kanye nezindlela zokufaka ezahlukahlukene kungahlangabezana nezidingo zokufaka zamakhasimende ahlukene ebhodi le-PCB.
I-Amass inobude obuhlukene bezixhumi zamabhodi wesekethe se-PCB anobukhulu obuhlukene, okuhambisana nezinga lomkhakha lobukhulu bephaneli eveziwe obungu-1.0-1.6mm ukuqinisekisa ukusetshenziswa okuvamile kwemishini!
