Iziphene ze-PCB kunye nolawulo oluphawuleleyo, njengoko sizabalazela ukugcina imigangatho ephezulu yokusebenza komgangatho kunye nokusebenza kakuhle, kubalulekile ukujongana nokunciphisa iziphene ezinomgangatho oqhelekileyo wePCB.

Kwinqanaba ngalinye lemveliso, iingxaki zinokwenzeka ukuba zibangela isiphene kwibhodi yesekethe egqityiweyo. Iziphene eziqhelekileyo zibandakanya i-welding, ukonakaliswa koomatshini, ungcoliseko, ukubeka iziphene, iziphene zangaphakathi, kunye neengxaki zokuqhuba, kunye neengxaki ezibonakalayo.

Ezi ziphene zinokukhokelela kwimijikelezo emifutshane yombane, isekethe evulekileyo, i-aesthetics engalunganga, ukunciphisa ukuthembeka, kunye nokusilela ngokupheleleyo kwe-PCB.

Uyilo lweSiphene kunye nokuQalisa izinto zoLondolozo zizizathu eziphambili eziphambili zeziphene ze-PCB.

Nazi ezinye zezona zinto ziphambili ze-PCB eziMveliso

1.Yilo

Uninzi lweziphene ze-PCB zivela kwiingxaki zoyilo. Izizathu eziqhelekileyo zoyilo zibandakanya indawo engonelanga phakathi kwemigca, ii-loops ezincinci ezijikeleze i-borehole, umgca obukhali ogqithileyo kwimveliso yemveliso, kunye nokuqina kwemigca enqabileyo okanye izithuba ezingenakufezekiswa yinkqubo yokwenziwa.

Eminye imizekelo ibandakanya iipatheni ze-Symetrical ezibeka umngcipheko kwimigibe ye-acid, itreyini ezintle ezinokonakaliswa yi-elektrostatic yokukhupha, kunye nemicimbi yokuhlamba ubushushu.

Ukwenza uyilo olubanzi lwenkqubo yokwenziwa (i-DFM) kunye nezikhokelo zokuyilwa kwe-PCB zinokuthintela isiphene esineziphene.

Ukubandakanya abanjineli bomenzi kwinkqubo yoyilo kuyanceda ukuvavanywa kwenkqubo. Izixhobo zokulinganisa kunye nemodeli inokuqinisekisa ukunyamezelana koyilo kuxinzelelo lwehlabathi lwehlabathi kwaye ichonge iindawo ezinengxaki. Uyilo olusebenzayo lwenzala linyathelo lokuqala elibalulekileyo ekunciphiseni isiphene sePCB esiqhelekileyo.

I-2.PCB ingcoliseko

Ukuvelisa i-PCB kubandakanya ukusetyenziswa kweekhemikhali ezininzi kunye neenkqubo ezinokukhokelela kungcoliseko. Ngexesha lokwenziwa kwemveliso, i-PCBS ingcoliswe ngokulula zizixhobo ezifana nentsalela ye-flux, ioyile yomnwe, isisombululo somnwe, i-acid plates, i-subgecle ye-temment kunye nentsalela yokucoca iarhente.

Ungcoliseko lubeka umngcipheko kwimijikelezo emifutshane yombane, isekethe evulekileyo, iziphene ze-welding, neengxaki zexesha elide. Ukunciphisa umngcipheko wokungcolisa ngokugcina iindawo zemveliso zicoceke kakhulu, kunyanzelisa ulawulo olungqongqo ulawulo, kwaye uthintele unxibelelwano lomntu. Uqeqesho lwabasebenzi kwiinkqubo ezifanelekileyo zokuphatha ibalulekile.

I-3.Maneter

Izixhobo ezisetyenziswa kwimveliso ye-PCB kufuneka zikhululwe kwiziphene zendalo. Izixhobo ze-PCB ezingangqinelaniyo (ezinje ngamagama asemgangathweni, i-Predgeres, i-foils, kunye nezinye izinto) zinokuqulatha iziphene ezingelilo i-resin engonelanga, i-fible fibles, kunye nee-pinseles.

Ezi ziphene zibonakalayo zinokubandakanywa kwiphepha lokugqibela kwaye zichaphazele ukusebenza. Ensuring that all materials are sourced from reputable suppliers with extensive quality control can help avoid material related issues. Ukuhlolwa kwezinto ezizayo kuyacetyiswa.

Ukongeza, ukonakaliswa komatshini, impazamo yomntu kunye neenguqu zenkqubo zingayichaphazela imveliso yePCB.

Iziphene zenzeka kwimveliso ye-PCB ngenxa yoyilo kunye nemveliso yemveliso. Ukuqonda ezona ziphene zixhaphakileyo zePCB zenza ukuba iifektri zigxile kubunzima bokugcinwa kokuThintela kunye nokuhlola. Imigaqo esisiseko yokuthenga ngokuthi yenze uhlalutyo loyilo, iinkqubo zokulawulwa ngokungqongqo, qeqesha abaqhubi, bahlole ngokugqibeleleyo, bagcine ucoceko, iibhodi zempazamo kunye nemigaqo-nkqubo yobungqina.
