bobabini ziibhodi zesekethe eziqinileyo eziguqukayo (PCBS) zisetyenziselwa ukuqhagamshela izinto zombane kwiintlobo ngeentlobo zabathengi kunye nezixhobo ezingezizo ezabathengi. Njengoko igama libonisa, i-PCB eqinileyo yibhodi yesekethe eyakhelwe kwisiseko esomeleleyo esingakwaziyo ukugoba, ngelixa i-PCB eguqukayo (ekwabizwa ngokuba yisekethe eguqukayo) yakhelwe kwisiseko esiguqukayo esinokugoba, ukujija, nokusonga.

Nangona zombini i-PCBS yendabuko kunye neguquguqukayo isebenza kwinjongo esisiseko efanayo, kubalulekile ukuba uqaphele ukuba kukho umahluko omkhulu phakathi kwabo. Imijikelezo eguqukayo ayisiyi-PCBS nje egobileyo; zenziwe ngokwahlukileyo kwi-PCBS engqongqo kwaye zineendlela ezahlukeneyo zokusebenza kunye nokungalunganga. Funda ngakumbi malunga ne-PCBS eqinile kwaye eguqukayo apha ngezantsi.

Uyintoni umahluko phakathi kwe-PCB engqongqo kunye nesekethe eguqukayo?

Ii-PCBS ezi-Rigid, zihlala zibizwa ngokuba zii-PCBS, zezinto abantu abaninzi abacinga ngazo xa becinga ngeebhodi zesekethe. La macwecwe adibanisa izinto zombane kusetyenziswa iileyili ezihamba kunye nezinye izinto ezilungiselelwe kwisiseko esingahambisiyo. Kwiibhodi zesekethe ezingqongqo, i-substrate engasebenziyo ihlala iqulethe iglasi eyomeleza amandla ebhodi kwaye iyinike amandla kunye nokuqina. Ibhodi yesekethe engqongqo ibonelela ngenkxaso elungileyo kwindibano kwaye ibonelela ngokuxhathisa okuhle kobushushu.

Olu hlobo lwebhodi yesekethe lusebenzisa i-substrate eguqukayo, enje nge-polyimide, nangona i-PCBS eguqukayo ikwanendlela yokuhamba kwiscate esingahambisiyo. Isiseko esiguqukayo sivumela imijikelezo ebhetyebhetye ukumelana neentshukumo, isasaze ubushushu kwaye isonge kwiimo ezahlukeneyo. Ngenxa yokulunga kwayo, iisekethe eziguqukayo ziya zisetyenziswa ngakumbi kwimveliso yecomputer kunye nezinto ezintsha ezenziwa ngombane.

Ukongeza kwimathiriyeli kunye nokuqina kobume besiseko, umahluko obonakalayo phakathi kwe-PCB kunye nesekethe eguqukayo ibandakanya:

Izinto zokuqhuba: Ngenxa yokuba imijikelezo ebhetyebhetye kufuneka igobile, abavelisi banokusebenzisa ubhedu olusongelweyo olubunjiweyo endaweni yobhedu oluqhubayo.

L Inkqubo yokuvelisa: Abavelisi beFlexible PCB abayisebenzisi i-solder blocking films, kodwa endaweni yoko basebenzise inkqubo ebizwa ngokuba ngaphezulu, okanye ukugquma ngaphezulu, ukukhusela isekethe ebonakalayo yePCB eguqukayo.

Iindleko eziqhelekileyo: Iisekethe eziguqukayo zihlala zibiza ngaphezulu kweebhodi eziqinileyo. Kodwa kuba iibhodi eziguqukayo zinokufakwa kwizithuba ezixineneyo, iinjineli zinokubunciphisa ubungakanani beemveliso zazo, ngaloo ndlela zonge imali ngokungangqalanga.

Ungayikhetha njani i-PCB engqongqo kunye neguqukayo

Iibhodi eziqinileyo neziguqukayo zinokusetyenziswa kwiimveliso ezininzi ezahlukeneyo, nangona ezinye izicelo zinokuxhamla ngakumbi kuhlobo olunye lwebhodi. Umzekelo, ii-PCBS eziqinileyo zenza ingqiqo kwiimveliso ezinkulu (ezinje ngeTV kunye neekhompyuter zekhompyuter), ngelixa iimveliso ezihambelana ngakumbi (ezinje ngee-smartphones kunye netekhnoloji enxitywayo) zifuna imijikelezo eguqukayo.

Xa ukhetha phakathi kwe-PCB engqongqo kunye ne-PCB eguqukayo, qwalasela iimfuno zakho zesicelo, uhlobo lwebhodi olukhethiweyo lomzi mveliso, kunye nefuthe lokusebenzisa olunye uhlobo okanye olo lunokuba luncedo.
