Abakinnyi benshi ba DIY bazasanga amabara ya PCB akoreshwa nibicuruzwa bitandukanye byamasoko bitangaje. Ibara risanzwe rya PCB ni umukara, icyatsi, ubururu, umuhondo, umutuku, umutuku n'umuhondo. Bamwe mubakora ibicuruzwa bakoze ubuhanga bwa PCBs y'amabara atandukanye nka cyera n'iroza.

Mubitekerezo gakondo, umukara PCB isa nkaho ihagaze kumpera ndende, mugihe umutuku numuhondo byeguriwe impera yo hasi. Ntabwo aribyo?

PCB y'umuringa wa PCB idashyizwe hamwe na mask yo kugurisha iba oxyde byoroshye iyo ihuye numwuka

Turabizi ko impande zombi za PCB ari umuringa. Mu musaruro wa PCB, umuringa uzabona ubuso bworoshye kandi butarinzwe utitaye ko bukozwe muburyo bwo kongeramo cyangwa gukuramo.

Nubwo imiterere yimiti yumuringa idakora nka aluminium, fer, magnesium, nibindi, imbere yamazi, umuringa usukuye byoroshye okiside ihuye na ogisijeni; kubera ko umwuka wa ogisijeni n'umwuka w'amazi bibaho mu kirere, hejuru y'umuringa usukuye uhura n'umwuka Oxidation reaction izabaho vuba.

Kubera ko umubyimba wumuringa uri muri PCB ari muto cyane, umuringa wa okiside uzahinduka umuyobozi mubi w'amashanyarazi, byangiza cyane amashanyarazi ya PCB yose.

Mu rwego rwo gukumira okiside y'umuringa, gutandukanya ibice byagurishijwe kandi bitagurishijwe bya PCB mugihe cyo kugurisha, no kurinda ubuso bwa PCB, abashakashatsi bahimbye igifuniko kidasanzwe. Ubu bwoko bw'irangi burashobora gukoreshwa muburyo bworoshye hejuru ya PCB kugirango habeho urwego rukingira hamwe nubunini runaka kandi bikabuza guhuza umuringa numwuka. Iki gipimo cyo gutwikira cyitwa masike yo kugurisha, kandi ibikoresho byakoreshejwe ni mask yo kugurisha.

Kubera ko yitwa lacquer, igomba kugira amabara atandukanye. Nibyo, mask yambere yo kugurisha irashobora gukorwa idafite ibara kandi ikorera mu mucyo, ariko kugirango byoroherezwe kubungabunga no gukora, PCBs ikenera gucapwa hamwe ninyandiko nto kurubaho.

Maskeri yo kugurisha ibonerana irashobora kwerekana gusa ibara ryinyuma rya PCB, isura rero ntabwo ari nziza bihagije haba mu gukora, gusana cyangwa kugurisha. Kubwibyo, injeniyeri yongeyeho amabara atandukanye kubagurisha masike kugirango bakore umukara cyangwa umutuku, ubururu PCB.

Umukara PCB biragoye kubona ibisobanuro, bizana ingorane zo kubungabunga

Duhereye kuriyi ngingo, ibara rya PCB ntaho rihuriye nubwiza bwa PCB. Itandukaniro riri hagati yumukara PCB nandi mabara PCBs nka PCB yubururu na PCB yumuhondo iri mu ibara rya mask yagurishijwe.

Niba igishushanyo cya PCB nuburyo bwo gukora ari kimwe, ibara ntirizagira ingaruka kumikorere, ntanubwo rizagira ingaruka kumirasire.

Kubyerekeranye na PCB yumukara, hejuru yubuso bwayo hafi yubusa, bitera ingorane zikomeye mukubungabunga nyuma, bityo rero ni ibara ritoroheye gukora no gukoresha.

Kubwibyo, mumyaka yashize, abantu bagiye bavugurura buhoro buhoro, bareka gukoresha mask yumukara wumukara, ahubwo bakoresha icyatsi kibisi cyijimye, umukara wijimye, ubururu bwijimye nubundi masike yabagurisha, ikigamijwe nukworohereza gukora no kubungabunga.

Tumaze kubivuga, abantu bose basobanukiwe ahanini ikibazo cyamabara ya PCB. Kubireba imvugo "ibara ryerekana cyangwa hasi-iherezo", ni ukubera ko abayikora bahitamo gukoresha PCB yumukara kugirango bakore ibicuruzwa byo mu rwego rwo hejuru, kandi umutuku, ubururu, icyatsi, n'umuhondo kugirango bakore ibicuruzwa byo hasi.

Inshamake ni: ibicuruzwa bitanga ibara ibisobanuro, ntabwo ibara ritanga ibicuruzwa ibisobanuro.
3.Ni izihe nyungu zo gukoresha ibyuma by'agaciro nka zahabu na feza kuri PCB?

Ibara rirasobanutse, reka tuvuge kubyuma byagaciro kuri PCB! Mugihe bamwe mubakora ibicuruzwa bazamura ibicuruzwa byabo, bazavuga byumwihariko ko ibicuruzwa byabo bikoresha inzira zidasanzwe nko gusiga zahabu na plaque. None ubu buryo bukoreshwa iki?

Ubuso bwa PCB busaba kugurisha ibice, bityo igice cyumuringa gisabwa kugaragara kugirango kigurishwe. Izi muringa zerekanwe zitwa padi. Amapadi muri rusange ni urukiramende cyangwa ruzengurutse hamwe n'umwanya muto.

Mubimaze kuvugwa haruguru, tuzi ko umuringa ukoreshwa muri PCB uhinduka okiside byoroshye, bityo nyuma yo gukoreshwa mask yo kugurisha, umuringa uri kuri padi uhura numwuka.

Niba umuringa uri kuri padi urimo okiside, ntabwo bigoye kugurisha gusa, ariko kandi no kurwanya biriyongera cyane, bigira ingaruka zikomeye kumikorere yibicuruzwa byanyuma. Kubwibyo, injeniyeri yazanye uburyo butandukanye bwo kurinda amakariso. Kurugero, yometseho zahabu ya inert, cyangwa hejuru yuzuyeho ifeza hifashishijwe uburyo bwa shimi, cyangwa firime idasanzwe yimiti ikoreshwa mugupfuka umuringa kugirango hirindwe guhuza padi numwuka.

Kubipapuro byerekanwe kuri PCB, umuringa ugaragara neza. Iki gice gikeneye kurindwa kugirango kirinde okiside.

Dufatiye kuri iyi ngingo, yaba zahabu cyangwa ifeza, intego yibikorwa ubwayo ni ukurinda okiside, kurinda padi, no kwemeza umusaruro muburyo bwo kugurisha nyuma.

Ariko, gukoresha ibyuma bitandukanye bizashyiraho ibisabwa mugihe cyo kubika no kubika PCB ikoreshwa muruganda rutanga umusaruro. Kubwibyo, inganda za PCB muri rusange zikoresha imashini zipakira za vacuum zipakira PCB nyuma yumusaruro wa PCB urangiye na mbere yo kugeza kubakiriya kugirango barebe ko PCB idahumeka neza.

Mbere yuko ibice bisudira kuri mashini, uruganda rwamakarita yubuyobozi rugomba kandi gusuzuma urugero rwa okiside ya PCB, kurandura PCB, no kwemeza umusaruro. Ikibaho umuguzi wa nyuma abona cyatsinze ibizamini bitandukanye. Ndetse na nyuma yo kumara igihe kinini ikoreshwa, okiside izaboneka gusa mugice cyo guhuza ibice, kandi nta ngaruka bizagira kuri padi nibice bimaze kugurishwa.

Ko kurwanya ifeza na zahabu biri hasi, nyuma yo gukoresha ibyuma bidasanzwe nka feza na zahabu, ubushyuhe bwa PCB buzagabanuka?

Turabizi ko ikintu kigira ingaruka kubushyuhe ni ukurwanya. Kurwanya bifitanye isano nibikoresho byuyobora ubwabyo, agace kambukiranya igice nuburebure bwuyobora. Ubunini bwibikoresho byicyuma hejuru ya padi ndetse ntibiri munsi ya 0,01 mm. Niba padi itunganijwe nuburyo bwa OST (organic organic film), ntihazabaho umubyibuho ukabije na gato. Kurwanya kwerekanwa nubunini buto hafi ya bingana na 0, ndetse ntibishoboka kubara, kandi birumvikana ko bitazagira ingaruka kubushyuhe.
