A ibhodi yesekethe eprintiweyo (PCB) yibhodi ebhityileyo eyenziwe kwi-fiberglass, i-epoxy ehlanganisiweyo, okanye ezinye izinto ezinqabileyo.PCBs zifumaneka kumacandelo ezahlukeneyo zombane kunye ne-elektroniki ezifana beepers, radios, radars, iinkqubo zekhompyutha, njalo njalo iintlobo ezahlukeneyo PCBs zisetyenziswa ngokusekelwe izicelo.Zeziphi iintlobo ezahlukeneyo zePCBs?Funda ukuze wazi.

Zeziphi iindidi ezahlukeneyo zeePCBs?

IiPCB zihlala zihlelwa ngokwesiseko sokuphindaphinda, inani leeleya kunye ne-substrate esetyenzisiweyo.Ezinye iintlobo ezidumileyo zixoxwa ngezantsi.

• IiPCB eziMacaleni omnye
  IiPCB ezisecaleni luhlobo olusisiseko lweebhodi zeesekethe, eziqulethe kuphela umaleko omnye we-substrate okanye izinto ezisisiseko.Umaleko ugqunywe ngumaleko obhityileyo wentsimbi, oko kukuthi ubhedu- nto leyo ingumbhexeshi olungileyo wombane.Ezi PCBs zikwanazo imaski yesolder ekhuselayo, esetyenziswa ngaphezulu komgangatho wobhedu kunye nedyasi yesikrini sesilika.Ezinye izibonelelo ezibonelelwa ziiPCB ezisecaleni zezi:
  • IiPCB ezisecaleni zisetyenziselwa ukuvelisa umthamo kwaye zinexabiso eliphantsi.
  • Ezi PCB zisetyenziselwa iisekethe ezilula ezifana nezinzwa zamandla, iirelays, izinzwa kunye nezinto zokudlala zombane.
• PCBs emacaleni kabini
  Ii-PCB ezinamacala amabini zinamacala omabini e-substrate ebonisa umaleko wentsimbi.Imingxuma kwibhodi yesiphaluka ivumela ukuba iindawo zetsimbi zifakwe ukusuka kwelinye icala ukuya kwelinye.Ezi PCBs ziqhagamshela iisekethe macala omabini nangayiphi na kwezi zikimu zimbini zokunyuka, ezizezi, itekhnoloji yomngxuma kunye neteknoloji yokunyuka komphezulu.Itheknoloji ye-through-hole ibandakanya ukufakwa kwamacandelo okukhokelela kwimingxuma esele ifakwe ngaphambili kwibhodi yesiphaluka, ezithengiswa kwiipads kumacala ahlukeneyo.Iteknoloji yokunyuka kwendawo ibandakanya amacandelo ombane ukuba abekwe ngokuthe ngqo phezu kweebhodi zeesekethe.Izinto eziluncedo ezinikezelwa ngamacala amabini PCB zezi:
  • Ukunyuswa komphezulu kuvumela iisekethe ezininzi ukuba zincanyathiselwe ebhodini xa kuthelekiswa nokuxhonywa komngxuma.
  • Ezi PCB zisetyenziswa kuluhlu olubanzi lwezicelo, kubandakanywa inkqubo ifowuni ephathwayo, esweni amandla, izixhobo uvavanyo, amplifiers, kunye nabanye abaninzi.
• IiPCB ezinamaleko amaninzi
  Multi-layer PCBs iibhodi zesekethe eprintiweyo, equka ngaphezu ezimbini umaleko zobhedu ezifana 4L, 6L, 8L, etc. Ezi PCBs ukwandisa iteknoloji esetyenziswa PCB amacala kabini.Iintlobo ezahlukeneyo zebhodi ye-substrate kunye nezixhobo zokugquma zahlula iileya kwii-PCB zamanqanaba amaninzi.IiPCBs zinobungakanani obubambeneyo, kwaye zibonelela ngezibonelelo zobunzima kunye nendawo.Ezinye iingenelo ezibonelelwa ziiPCB ezinamaleko amaninzi zezi:
  • IiPCB ezinamaleko amaninzi zibonelela ngenqanaba eliphezulu lokuguquguquka koyilo.
  • Ezi PCB zidlala indima ebalulekileyo kwiisekethe zesantya esiphezulu.Banika indawo eyongezelelweyo yepateni yomqhubi kunye namandla.
• IiPCB eziqinileyo
  Ii-PCB eziqinileyo zibhekisa kwezo ntlobo zee-PCB ezisisiseko semathiriyeli eyenziwe ngesixhobo esiqinileyo nesingenako ukugotywa.Ezinye zezinto eziluncedo ezibonelelwa ngabo:
  • Ezi PCB zixinene, eziqinisekisa ukuyilwa kweendidi zesekethe ezintsonkothileyo ezijikeleze kuyo.
  • Ii-PCB eziqinileyo zibonelela ngokulungiswa nokugcinwa lula, njengoko onke amacandelo ephawulwe ngokucacileyo.Kwakhona, iindlela zomqondiso zicwangciswe kakuhle.
• PCBs Flexible
  PCBs Flexible zakhiwe kwisiseko semathiriyeli eguqukayo.Ezi PCB ziza kwicala elinye, amacala amabini kunye nefomathi yale mininzi.Oku kunceda ekunciphiseni ubunzima ngaphakathi kwindibano yesixhobo.Ezinye iingenelo ezibonelelwa zezi PCB zezi:
  • Ezi PCBs zinceda ukugcina indawo eninzi, kunye nokunciphisa ubunzima bebhodi.
  • IiPCB eziguquguqukayo zinceda ekwehliseni ubungakanani bebhodi, nto leyo eyenza ukuba ilungele usetyenziso olwahlukeneyo apho kufuneka uxinaniso lomkhondo wophawu oluphezulu.
  • Ezi PCB ziyilelwe iimeko zokusebenza, apho ubushushu kunye noxinaniso yeyona nto ixhalabisayo.
• Rigid-Flex-PCBs
  IiPCB eziguquguqukayo eziqinileyo yindibaniselwano yeebhodi zesekethe eziqinileyo neziguquguqukayo.Ziquka iileya ezininzi zeesekethe eziguquguqukayo ezincanyathiselwe ngaphezu kwebhodi enye eqinileyo.
  • Ezi PCB zichanekile zakhiwe.Ke, isetyenziswa kwizicelo ezahlukeneyo zonyango kunye nezomkhosi.
  • Ukuba ukukhanya-ubunzima, ezi PCB zibonelela 60% ubunzima kunye nendawo yokonga.
• High-Frequency PCBs
  Ii-PCB ze-high-frequency zisetyenziswa kwi-frequency range ye-500MHz - 2GHz.Ezi PCB zisetyenziswa kwiinkqubo ezahlukeneyo zokuphindaphinda ezibalulekileyo ezifana neenkqubo zonxibelelwano, iiPCB zemicrowave, iiPCB zemicrostrip, njl.
• Aluminiyam backed PCBs
  Ezi PCB zisetyenziswa kwizicelo zamandla aphezulu, njengoko ulwakhiwo lwe-aluminiyam lunceda ekuchitheni ubushushu.Aluminiyam backed PCBs zaziwa ukuba zinika inqanaba eliphezulu ukuqina kunye nenqanaba eliphantsi lokwandiswa thermal, nto leyo eyenza ukuba ilungele izicelo ukuba unyamezelo ngoomatshini eliphezulu.IiPCB zisetyenziselwa ii-LED kunye nokubonelela ngombane.

Imfuno ye-PCBs ifikelela kumacandelo ahlukeneyo amashishini.Namhlanje, uya kufumana ezahlukeneyo abavelisi bePCB abadumileyo kunye nabasasazi, ababonelela imarike yezixhobo ezinxibelelanayo ezikhuphisanayo.Kuhlala kucetyiswa ukuba kuthengwe ii-PCBs zosetyenziso lwemizi-mveliso kunye nezorhwebo kubavelisi abadumileyo kunye nababoneleli.Imigca ephothiweyo yenye abavelisi abathembekileyo nabanamava eentlobo ezahlukeneyo zeePCB.Inkampani isoloko ibonelela abathengi bayo ngeebhodi zesekethe ezikumgangatho ophezulu ngesantya esiphezulu, kunye nokusebenza.
