Mu myaka yashize, abantu hafi ya bose bafite ibikoresho bya elegitoroniki birenze kimwe, kandi inganda za elegitoroniki zateye imbere byihuse, ari nazo zatumye izamuka ryihuse ryinganda zumuzunguruko wa PCB. Mu myaka yashize, abantu bafite ibyangombwa byinshi kandi bisabwa kugirango bakoreshe ibicuruzwa bya elegitoroniki, ibyo bikaba byanatumye hasabwa byinshi kandi bisabwa kugirango ubuziranenge bwibibaho. Nigute ushobora gutandukanya ubuziranenge bwibibaho byumuzunguruko wa PCB byabaye ingingo yo kongera impungenge.

Uburyo bwa mbere ni ubugenzuzi bugaragara, aribwo ahanini kugenzura isura yumuzunguruko. Ikintu cyibanze cyo kugenzura isura ni ukureba niba ubunini nubunini bwibibaho byujuje ubunini nibisobanuro ukeneye. Niba atari byo, ugomba kongera kubikora. Byongeye kandi, hamwe n’amarushanwa akaze ku isoko rya PCB, ibiciro bitandukanye bikomeje kwiyongera. Kugirango ugabanye ibiciro, ababikora bamwe bakomeje kugabanya ibiciro byibiciro nibicuruzwa. Amabati asanzwe HB, cem-1, na cem-3 afite imikorere mibi kandi byoroshye guhinduka, kandi irashobora gukoreshwa gusa kubyara umusaruro umwe, mugihe fr-4 ya fiberglass paneli iba nziza cyane mumbaraga no mubikorwa, kandi ikoreshwa kenshi mu mpande ebyiri kandi impande nyinshi. Umusaruro wa laminates. Ikibaho gikozwe mu mbaho ​​zo mu rwego rwo hasi akenshi zifite ibice n'ibishushanyo, bigira ingaruka zikomeye ku mikorere y'ibibaho. Aha kandi niho ukeneye kwibanda ku kugenzura amashusho. Mubyongeyeho, niba uwagurishije mask wino yuzuye aringaniye, niba hari umuringa wagaragaye; niba imiterere ya silike ya ecran irahagarikwa, niba padi iri cyangwa idakeneye kwitabwaho.

Nyuma yuburyo bwa kabiri bugomba gukoreshwa, busohoka binyuze mubitekerezo. Mbere ya byose, irashobora gukoreshwa mubisanzwe nyuma yibigize. Ibi bisaba ko ikibaho cyumuzunguruko kidafite uruziga rugufi cyangwa uruziga rufunguye. Uruganda rufite ibizamini byamashanyarazi mugihe cyo gukora kugirango hamenyekane niba ikibaho gifite uruziga rufunguye cyangwa rugufi. Nyamara, bamwe mubakora inama y'ubutegetsi bazigama Ikiguzi ntigishobora gupimwa amashanyarazi (Proofing at Jiezi, isezerano ryamashanyarazi 100% ryasezeranijwe), iyi ngingo rero igomba gusobanurwa mugihe cyemeza ikibaho cyumuzunguruko. Noneho reba ikibaho cyumuzunguruko kubyara ubushyuhe mugihe cyo gukoresha, bifitanye isano nimba umurongo ubugari / umurongo intera yumuzingi kurubaho bifite ishingiro. Mugihe cyo kugurisha ibishishwa, birakenewe kugenzura niba padi yaguye mubihe byubushyuhe bwinshi, bigatuma bidashoboka kugurisha. Mubyongeyeho, ubushyuhe bwo hejuru bwo kurwanya ikibaho nabwo ni ngombwa cyane. Icyerekezo cyingenzi cyinama ni agaciro ka TG. Mugihe ukora isahani, injeniyeri akeneye gutegeka uruganda rwubuyobozi gukoresha ikibaho kijyanye nuburyo bukoreshwa. Hanyuma, igihe gisanzwe cyo gukoresha cyinama nacyo kimenyetso cyingenzi cyo gupima ubuziranenge bwinama.

Iyo tuguze imbaho ​​zumuzunguruko, ntidushobora guhera kubiciro byonyine. Tugomba kandi gutekereza ku bwiza bwibibaho byumuzunguruko hanyuma tugasuzuma ibintu byose mbere yuko tugura imbaho ​​zikoresha neza.
