Iziphene zePCB kunye nolawulo loMgangatho, njengoko sizama ukugcina imigangatho ephezulu yomgangatho kunye nokusebenza kakuhle, kubalulekile ukujongana nokunciphisa ezi ziphene zePCB eziqhelekileyo.
Kwinqanaba ngalinye lokuvelisa, iingxaki zinokuthi zenzeke ezibangela iziphene kwibhodi yesekethe egqityiweyo. Iziphene eziqhelekileyo zibandakanya ukuwelda, ukonakala koomatshini, ungcoliseko, ukungachaneki komgangatho, iziphene zeplating, iileya zangaphakathi ezingalungelelanisiweyo, iingxaki zokomba, kunye neengxaki zempahla.
Ezi ziphene zinokukhokelela kwiisekethe ezimfutshane zombane, iisekethe ezivulekileyo, i-aesthetics engalunganga, ukuthembeka okuncitshisiweyo, kunye nokusilela okupheleleyo kwePCB.
Iziphene zoyilo kunye nokwahluka kwemveliso zezona zizathu zimbini zeziphene zePCB.
Nazi ezinye zezona zizathu ziphambili zeziphene zokwenziwa kwe-PCB eziqhelekileyo:
1.Uyilo olungafanelekanga
Iziphene ezininzi zePCB zivela kwiingxaki zoyilo. Izizathu eziqhelekileyo ezinxulumene noyilo zibandakanya ukungonelanga kwesithuba phakathi kwemigca, iilophu ezincinci ezijikeleze i-borehole, ii-angles zemigca ezibukhali ezidlula amandla okuvelisa, kunye nokunyamezela imigca emincinci okanye izikhewu ezingenakufezekiswa yinkqubo yokuvelisa.
Eminye imizekelo ibandakanya iipateni ezilinganayo ezibeka umngcipheko wemigibe ye-asidi, imikhondo emihle engonakaliswa kukukhutshwa kwe-electrostatic, kunye nemiba yokutshatyalaliswa kobushushu.
Ukwenza uhlalutyo olubanzi lwe-Design for Manufacturability (DFM) kunye nokulandela izikhokelo zoyilo lwe-PCB kunokuthintela iziphene ezininzi ezibangelwa kuyilo.
Ukubandakanya iinjineli zemveliso kwinkqubo yoyilo kunceda ukuvavanya ukwenziwa kwezinto. Izixhobo zokulinganisa kunye nemodeli zinokuqinisekisa ukunyamezela koyilo kuxinzelelo lwehlabathi lokwenyani kunye nokuchonga iindawo eziyingxaki. Ukuphucula uyilo lokwenziwa linyathelo lokuqala elibalulekileyo ekucutheni iziphene eziqhelekileyo zokwenziwa kwePCB.
2.PCB ungcoliseko
Ukwenziwa kwePCB kubandakanya ukusetyenziswa kweekhemikhali ezininzi kunye neenkqubo ezinokukhokelela kungcoliseko. Ngexesha lenkqubo yokuvelisa, i-PCBS ingcoliseka ngokulula ngezinto ezifana neentsalela ze-flux, i-oyile yomnwe, isisombululo se-acid plating, i-particle debris kunye ne-ejenti yokucoca iintsalela.
Izinto ezingcolisayo zibeka umngcipheko weesekethe ezimfutshane zombane, iisekethe ezivulekileyo, iziphene ze-welding, kunye neengxaki ze-corrosion zexesha elide. Nciphisa umngcipheko wongcoliseko ngokugcina iindawo zemveliso zicoceke kakhulu, unyanzelise ulawulo olungqongqo longcoliseko, kunye nokuthintela ukudibana nabantu. Uqeqesho lwabasebenzi kwiinkqubo zokuphatha ngendlela eyiyo nalo lubalulekile.
3.isiphene sezinto eziphathekayo
Izinto ezisetyenziswa kwi-PCB yokwenziwa kufuneka zingabinaziphene. Iimathiriyeli ze-PCB ezingahambelaniyo (ezifana ne-laminates ezikumgangatho ophantsi, prepregs, foil, kunye namanye amacandelo) zinokuqulatha iziphene ezifana ne-resin engonelanga, i-glass fiber protrusions, pinholes, kunye namaqhuqhuva.
Ezi ziphene eziphathekayo zingabandakanywa kwiphepha lokugqibela kwaye zichaphazele ukusebenza. Ukuqinisekisa ukuba zonke imathiriyeli zifunyenwe kubaboneleli abathembekileyo abanolawulo olubanzi lomgangatho kunokunceda ukuphepha imiba enxulumene nezinto. Ukuhlolwa kwezinto ezingenayo nazo kuyacetyiswa.
Ukongeza, umonakalo oomatshini, impazamo yomntu kunye notshintsho lwenkqubo lunokuchaphazela ukwenziwa kwe-pcb.
Iziphene zenzeka kwi-PCB yokuvelisa ngenxa yoyilo kunye nokuvelisa izinto. Ukuqonda ezona ziphene zePCB zixhaphakileyo zenza ukuba iifektri zigxile ekuthinteleni ekujoliswe kuzo kunye neenzame zokuhlola. Imigaqo esisiseko yokhuseleko kukwenza uhlalutyo loyilo, iinkqubo zokulawula ngokungqongqo, abaqhubi boololiwe, bahlole ngokucokisekileyo, bagcine ucoceko, iibhodi zomkhondo kunye nemigaqo yobungqina bempazamo.
