Amateka yo kugurisha imiraba

Uruganda rukora ibicuruzwa bya Chengyuan ruzakumenyesha ko kugurisha imiraba byabayeho mumyaka mirongo, kandi nkuburyo nyamukuru bwo kugurisha ibice, byagize uruhare runini mukuzamura imikoreshereze ya PCB.

Hariho gusunika cyane kugirango ibikoresho bya elegitoroniki bito kandi bikore, kandi PCB (umutima wibi bikoresho) ituma ibi bishoboka.Iyi myumvire kandi yabyaye uburyo bushya bwo kugurisha nkuburyo bwo kugurisha imiraba.

Mbere yo Kugurisha Umuhengeri: Amateka y'Inteko ya PCB

Kugurisha nkibikorwa byo guhuza ibice byibyuma bikekwa ko byagaragaye nyuma gato yo kuvumbura amabati, na nubu bikaba byiganje mubagurisha muri iki gihe.Kurundi ruhande, PCB yambere yagaragaye mu kinyejana cya 20.Umuhimbyi w’umudage Albert Hansen yazanye igitekerezo cyindege nyinshi;bigizwe no kubika ibice hamwe na fayili.Yasobanuye kandi imikoreshereze y’imyobo mu bikoresho, ubwo bukaba aribwo buryo bumwe bwakoreshejwe muri iki gihe mu kwinjiza ibice.

Mu Ntambara ya Kabiri y'Isi Yose, iterambere ry'ibikoresho by'amashanyarazi na elegitoroniki ryatangiye mu gihe ibihugu byashakaga kunoza itumanaho no kumenya ukuri cyangwa neza.Uwahimbye PCB igezweho, Paul Eisler, yateguye inzira mu 1936 yo guhuza ifu y'umuringa mu kirahure gikingira ikirahure.Nyuma yaje kwerekana uburyo bwo guteranya radio ku gikoresho cye.Nubwo ikibaho cye cyakoreshaga insinga kugirango zihuze ibice, inzira itinze, umusaruro wa PCBs ntabwo wasabwaga icyo gihe.

Kuzunguruka Umuhengeri Kubatabazi

Mu 1947, transistor yahimbwe na William Shockley, John Bardeen, na Walter Brattain muri Laboratoire ya Bell i Murray Hill, muri Leta ya New Jersey.Ibi byatumye igabanuka ryubunini bwibikoresho bya elegitoroniki, kandi iterambere ryakurikiyeho mugutobora no kumurika byatanze inzira yubuhanga bwo kugurisha urwego.
Kubera ko ibikoresho bya elegitoronike bikiri mu mwobo, biroroshye guha abagurisha icyarimwe icyarimwe, aho kubigurisha kugiti cyabo hamwe nicyuma.Rero, kugurisha umuraba byavutse mugukoresha ikibaho cyose hejuru ya "waves" yumugurisha.

Uyu munsi, kugurisha imiraba bikorwa na mashini yo kugurisha.Inzira ikubiyemo intambwe zikurikira:

1. Gushonga - Ugurisha ashyushye kugeza kuri 200 ° C kuburyo bitemba byoroshye.

2. Isuku - Sukura ibice kugirango umenye neza ko nta mbogamizi zibuza uwagurishije gukomera.

3. Gushyira - Shyira PCB neza kugirango ugurisha ageze mubice byose byubuyobozi.

4. Gusaba - Solder ikoreshwa ku kibaho kandi yemerewe gutembera ahantu hose.

Ejo hazaza ha Soldering

Kugurisha imiraba yahoze ikoreshwa muburyo bwo kugurisha.Ibi ni ukubera ko umuvuduko wacyo uruta kugurisha intoki, bityo ukamenya automatike yinteko ya PCB.Inzira ninziza cyane kugurisha byihuse, ahantu heza hifashishijwe ibice.Nkuko ibyifuzo bya PCB bito biganisha ku gukoresha imbaho ​​nyinshi hamwe nibikoresho byo hejuru (SMDs), tekinoroji yo kugurisha neza igomba gutezwa imbere.

Ibi biganisha ku buryo bwo guhitamo uburyo bwo kugurisha aho amasano agurishwa kugiti cye, nko kugurisha intoki.Iterambere muri robo ryihuta kandi risobanutse kuruta gusudira intoki byatumye bishoboka uburyo bwo gukoresha uburyo.

Kugurisha imiraba bikomeje kuba tekinike yashyizwe mubikorwa kubera umuvuduko wacyo no guhuza nibisabwa bishya bya PCB bifasha gukoresha SMD.Kugurisha ibicuruzwa byatoranijwe byagaragaye, bikoresha jetting, ituma ikoreshwa ryumugurisha rigenzurwa kandi ryerekejwe ahantu hatoranijwe gusa.Ibice binyujijwe mu mwobo biracyakoreshwa, kandi kugurisha umurongo ni tekinike yihuse yo kugurisha vuba umubare munini wibigize, kandi birashobora kuba uburyo bwiza, bitewe nigishushanyo cyawe.

Nubwo ikoreshwa ryubundi buryo bwo kugurisha, nko kugurisha ibicuruzwa byatoranijwe, bigenda byiyongera, kugurisha imiraba biracyafite ibyiza bituma bihinduka inteko ya PCB.
