Amabhodi esekethe aphrintiwe (ama-PCB) ayingxenye ebalulekile yazo zonke izisetshenziswa zikagesi esizisebenzisayo namuhla. Bahlinzeka ngesisekelo sezingxenye ze-elekthronikhi, ukuqinisekisa ukusebenza okulungile nokuxhumeka kukagesi. Kodwa-ke, lapho uklama i-PCB, ukukhetha izinto ezifanele kungaba nomthelela omkhulu ekusebenzeni, ukuqina, kanye nokuphumelela kwezindleko zomkhiqizo wokugcina. Kule bhulogi, sizobheka izici ezihlukahlukene okufanele zicatshangelwe lapho kukhethwa izinto ze-PCB.
Funda mayelana nezinto ze-PCB:
Kunezinhlobo eziningi zezinto ze-PCB, ngayinye enezakhiwo nezinzuzo ezahlukene. Ezinye izinto ezijwayelekile ezisetshenziswa ekwenziweni kwe-PCB zifaka i-FR-4, i-Polyimide, i-Rogers, ne-Aluminium. Ngokuqonda izakhiwo zalezi zinto, ungenza izinqumo ezinolwazi ngokusekelwe ezidingweni zakho zokuklama.
Izinto okufanele zicatshangelwe:
1. Izakhiwo zikagesi: Izakhiwo zikagesi zezinto ze-PCB zidlala indima ebalulekile ekunqumeni ukufaneleka kwayo kuhlelo oluthile. Cabangela ukungaguquguquki kwe-dielectric, isici sokulahlekelwa, ne-tangent yokulahlekelwa. Lezi zici zithinta ubuqotho besignali, ukulawulwa kwe-impedance, namandla okubamba amandla.
2. I-Thermal conductivity nokuphathwa: Ikhono lezinto ze-PCB zokuqeda ukushisa kubalulekile, ikakhulukazi ezinhlelweni zokusebenza zamandla aphezulu. Bheka izinto ezine-conductivity ephezulu yokushisa ukuze uqinisekise ukuchithwa kokushisa okuphelele futhi unciphise ingozi yokushisa ngokweqile kanye nokwehluleka kwengxenye.
3. Amandla emishini nokuqina: Amandla omshini wezinto ze-PCB anquma ukumelana kwayo nengcindezi, ukudlidliza nokugoba. Kufanele ikwazi ukumelana nezimo zemvelo lapho i-PCB isetshenziswa khona. Cabangela izici ezinjengamandla okuqina, amandla aguquguqukayo kanye nokumelana nomthelela.
4. Izindleko Nokutholakala: Izindleko nokutholakala kungahluka kakhulu ngaphakathi kwesikhala sezinto ze-PCB. Cabangela isabelomali esabelwe iphrojekthi bese usikala ngokuhambisana nezimfanelo ozifunayo. Ezinye izinto zingase zinikeze ukusebenza okuphezulu kodwa ngentengo ephezulu, kuyilapho ezinye zingabiza kakhulu kodwa zibe nokutholakala okulinganiselwe.
5. Inqubo yokukhiqiza: Izinto ezihlukile ze-PCB zidinga izinqubo ezihlukene zokukhiqiza. Ezinye izinto ezisetshenziswayo zifaneleka kangcono ukuhlanganisa ngokwesiko ngembobo, kanti ezinye zifaneleka kangcono kubuchwepheshe bokukhweza komhlaba (SMT). Ukuqonda inqubo yokukhiqiza kanye nokuhambisana kwezinto ezikhethiwe kubalulekile ukuze kugwenywe izinkinga zokukhiqiza.
Indaba Eyisibonelo: Ukukhetha Okubalulekile Kwe-PCB Yezinhlelo Zokusebenza Zemvamisa Ephakeme:
Ake sicabangele isimo: I-PCB iyadingeka kumasekhethi anemvamisa ephezulu yempahla yokuxhumana engenantambo. Kulokhu, into efana ne-Rogers PCB ingaba yinhle. Izinto ze-Rogers zine-dielectrics yokulahlekelwa okuphansi eqinisekisa ukulahlekelwa kwesignali okuncane kumafrikhwensi aphezulu. Futhi banokusebenza okuhle kakhulu kwe-thermal, okubenza bafaneleke imiklamo yamandla aphezulu akhiqiza ukushisa okukhulu.
Inqubo yokukhetha impahla ye-PCB iyisinyathelo esibalulekile ekwakhiweni kwedivayisi kagesi. Ngokucabangela izici ezifana nokusebenza kukagesi, ukuqhutshwa kwe-thermal, amandla emishini, izindleko, ukutholakala, nokuhambisana kokukhiqiza, ungakhetha into ehlangabezana nezidingo zephrojekthi yakho. Khumbula ukuhlaziya izidingo ezithile zesicelo sakho ukuze wenze isinqumo unolwazi. Izinto ezikhethwe ngokucophelela ze-PCB zizothuthukisa ukusebenza nokuthembeka kwemiklamo yakho ye-elekthronikhi.
