Ukubaluleka kwama-PCB anemvamisa ephezulu ekukhiqizeni ama-Electronics
Njengoba izinto zikagesi ziqhubeka nokuthuthuka ngobunkimbinkimbi futhi zifuna ngokusheshaizinga lokudlulisa isignalis, ama-PCB anemvamisa ephezulu abe yingxenye ebalulekile ekuthuthukisweni kwe uhlelo lokusebenza olusebenza kahle kakhuluskuwo wonke umkhakha wokukhiqiza.
Imvamisa ephezuluibhodi lesifunda eliphrintiweama-(PCBs) asebaluleke kakhulu ekukhiqizeni izinto zikagesi, ehlinzeka ngezinhlobonhlobo zezici ezibalulekile. Empeleni, ama-PCB anemvamisa ephezulu asakaza kahleigagasi kagesis ngokulahlekelwa okuncane futhi uqinisekiseukugeleza kwesignali yesivinini esikhulu. Izakhiwo eziyinhloko ezihlotshaniswa nama-PCB wemvamisa ephezulu zifaka:
PhansiI-Disipation Factor: Ama-PCB anemvamisa ephezulu ngokuvamile abonisa isici sokulahla esisuka ku-0.0019 siye ku-0.025, siqinisekisa okuncaneukulahlekelwa kwesignali kanye nokugcina izinga lokudlulisa isignalis.
PhansiI-Dielectric Constant: Lawa ma-PCB afaka i-dielectric engaguquki ephansi futhi ezinzile, eyenza kube busheleleziukudluliswa kwemvamisakanye nokunciphisaukubambezeleka kwesignali.
Ukumelana Namakhemikhali: Ikhono lama-PCB anemvamisa ephezulu ukumelana nokuchayeka kumakhemikhali libaluleke kakhulu, liqinisekisa ukumelana nokugqwala nokufaneleka kwezindawo ezinokuchayeka amakhemikhali abalulekile.
Ukumuncwa Komswakama Ophansi: Ngezinga eliphansi lokumunca amanzi, ama-PCB anemvamisa ephezulu afaneleka kahle ukuthi asetshenziswe ezindaweni eziswakeme nezinomswakama.
PhansiUkuzinza kweDimensional: Ama-PCB anemvamisa ephezulu abonwa ngokugcina usayizi wawo futhi ahlale engathinteki ukushintsha kwezinga lokushisa kwemvelo.
Njengoba kunikezwe lezi zici, ukusetshenziswa kwazo kusabalele. Nokho, abaklami be-PCB kumele baqinisekise ukuthi lezi zinyathelo ezilandelayo zilandelwa ngokucophelela lapho kwakhiwa ama-PCB anemvamisa ephezulu:
Nquma i-PCB imvamisa yesignali: Kubalulekile ukusungula izidingo ze-voltage namandla, uhlukanise noma yikuphiindiza yamandlas, kanye nokuhlola ukutholakala kwamasignali ahlukene. Ukwengeza, ukunciphisa amazinga okubekezelelana nokunciphisa amazinga omsindo yizinto ezibalulekile zokucatshangelwa.
Isitaki sebhodiukuhlela: Izidingo ze ungqimba lwesitakikufanele kuhlelwe ngokucophelela, kucatshangelwa ukwaziswa okuqondile kanye nokulinganiselwa kwakho.
Ukuhlelwa kwaphansi: I-PCB kufanele ihlukaniswe ngezigaba, ngokuhlukaniswa okufanele okugcinwa ezindaweni eziqukethe izingxenye zedijithali ne-analog ukuvimbela ukuphazamiseka.
Amandla kanyeindiza yaphansis: Uma isakhiwo se-PCB sesichaziwe, ukuqonda uhlelo lwaphansi kubalulekile. Ukuhlukanisa indiza yaphansi kubalulekile, futhi kufaka phakathi isixhasi kanye nomkhondo wesignali ukuze kuthuthukiswe indlela ebuyayo kubalulekile.
Yehlisa usayizi wamaphethini omhlaba: Ama-PCB anemvamisa ephezulu ngokuvamile afaka amaphedi amancane. Ukunciphisa isikhala kusiza ukunciphisa i-parasite capacitancefuthi kwandisa amandla mechanical.
Umzila weisignali yefrikhwensis: Amasignali amaza aphezulu ayaziwa ngokukhiqiza imisebe ephezulu. Umzila osebenzayo wamasignali wefrikhwensi ungavimbela ukuphazamiseka phakathi kwamasignali.
Sebenzisa umthetho we-3W: Ukunamathela kumthetho we-3W kuqinisekisa ukuthi ubuqotho besignali buyagcinwa, kuveza umehluko phakathi kokulandela umkhondo nokunciphisa umphumela wokuhlanganisa.
Sebenzisa umthetho we-20H: Ukuhlangana phakathi kwezindiza eziphansi nezinamandla kungase kube usongo ekwakhiweni kwakho. Umthetho we-20H uqinisekisa ukuthi ukushuba phakathi kwamandla aseduze nezindiza eziphansi kukhulu kunendiza yamandla.
Ukusetshenziswa kwe-High-Frequency PCBs
Ukusetshenziswa kwama-PCB anemvamisa ephezulu kuya ngokuya kwanda, nezinhlelo zokusebenza ezihlanganisa:
Amasistimu okuxhumana kumishini yokuhlunga, i-amplifiers,i-booster stations, kanyeumamukelis.
Izicelo zezempi zokukhiqizwa kwezinhlamvu nezibhamu.
Isistimu ye-radars eziqondisa izindiza futhi zinqande izingozi.
Imishini yokuxilonga nokuqapha ebalulekile embonini yezokwelapha.
Ekuphetheni
Ama-PCB anemvamisa ephezulu abalulekile ekwenziweni kwe-electronics PCB, enikeza izici eziqinile eziwenza abe yinketho ekhethwayo yezinto zikagesi. Badlala indima ebalulekile ezinhlelweni zokusebenza ezisebenza kahle kakhulu futhi sebekulungele ukubaluleka nakakhulu ngokukhula kwenkimbinkimbi yezinto zikagesi kanye nesidingo samazinga okudlulisa amasignali asheshayo.
