Uburemere bw'umuringa bwo gukora PCB: Ubuyobozi bwibanze

Ibibaho byacapwe (PCBs) nibice bigize ibikoresho bya elegitoroniki bigezweho. Bakora nkumugongo wibikoresho bya elegitoronike, bitanga urubuga rwo guhuza ibice bya elegitoroniki.Umuringa nuyobora amashanyarazi meza kandi akoreshwa cyane mubikorwa bya PCB.

Mubikorwa byo gukora PCB, uburemere bwumuringa bugira uruhare runini.Uburemere bw'umuringa bivuga ubunini cyangwa ingano y'umuringa ushyirwa hejuru y'urubaho. Uburemere bwumuringa ukoreshwa mubikorwa bya PCB bigira ingaruka kuburyo butaziguye amashanyarazi nubukanishi bwibibaho. Muri iyi blog, tuzasesengura uburemere butandukanye bw'umuringa bukoreshwa mu gukora PCB n'akamaro kabyo.

Gusobanukirwa Uburemere bw'umuringa mu gukora PCB

Uburemere bw'umuringa busanzwe bupimwa muri ounci kuri metero kare (oz / ft²). Uburemere bw'umuringa bukoreshwa cyane mubikorwa bya PCB biva kuri 0.5 oz / metero kare (17 µm) kugeza kuri 3 oz / metero kare (105 µm). Ibipimo byerekana uburebure bwumuringa bwububiko bwa PCB bwo hanze, ibice byimbere, hamwe nu mwobo wasizwe.

Guhitamo uburemere bwumuringa biterwa nibintu nkibisabwa amashanyarazi asabwa, imbaraga za mashini nigiciro. Reka

reba neza uburemere butandukanye bwumuringa nibisabwa mubikorwa bya PCB.

1. 0.5 oz / ft2 (17 µm) Uburemere bw'umuringa:
Nuburemere bworoshye bwumuringa bukoreshwa mugukora PCB. Ubusanzwe ikoreshwa muburyo bworoshye kandi bworoshye PCB. Izi mbaho ​​zikunze gukoreshwa mubikoresho bya elegitoroniki byabaguzi aho ikiguzi nuburemere aribintu byingenzi bitekerezwaho. Ariko, kugabanuka kwumuringa bigira ingaruka kubushobozi bwo gutwara imigezi myinshi kandi bishobora kuvamo kwiyongera.

2. 1 oz / metero kare (35 µm) uburemere bwumuringa:
Nuburemere bukoreshwa cyane mumuringa mubikorwa bya PCB. Iringaniza hagati yimikorere nigiciro-cyiza. PCB hamwe na 1 oz / sq. Uburemere bwumuringa burashobora gukoresha imiyoboro igereranije kandi nibyiza mubikorwa bitandukanye, harimo itumanaho, ibinyabiziga ninganda za elegitoroniki.

3. 2 oz / metero kare (70 µm) uburemere bwumuringa:
Mugihe ibyifuzo byubushobozi bwo gutwara ibintu byiyongera, PCBs zifite uburemere bwumuringa bwa ounci 2 / metero kare biba ngombwa. Azwiho kunoza ubushyuhe bwumuriro, izi mbaho ​​zisanzwe zikoreshwa mumashanyarazi ya elegitoronike, imbaraga zongera ingufu, sisitemu ya UPS nibindi bikorwa bisaba ubushobozi bukomeye bwo gutwara.

4. 3 oz / ft2 (105 µm) Uburemere bw'umuringa:
PCBs ifite uburemere bwumuringa bwa ounci 3 kuri metero kare bifatwa nkibibaho biremereye byumuringa. Izi mbaho ​​zikoreshwa mubisabwa bisaba ubushobozi bunini bwo gutwara cyangwa gukwirakwiza ubushyuhe bwiza. Ingero zimwe zirimo sisitemu yo gukwirakwiza ingufu, amashanyarazi yumuriro-mwinshi, hamwe na moteri.

Akamaro k'uburemere bw'umuringa mu gukora PCB

Guhitamo uburemere bwumuringa birakenewe kugirango PCB ikore neza kandi yizewe. Hano hari ibintu by'ingenzi byerekana akamaro k'uburemere bw'umuringa:

1. Imashanyarazi:
Uburemere bw'umuringa bugena ubushobozi bwa PCB bwo gutwara amashanyarazi atarinze guhangana cyane. Umubyimba udahagije wumuringa urashobora gutera imbaraga zo kuzamuka, bikaviramo kugabanuka kwa voltage hamwe nubushyuhe bukabije. Kurundi ruhande, uburemere bwumuringa burenze butuma uburyo bukoreshwa neza hamwe no kurwanya bike.

2. Imbaraga za mashini:
Usibye kuba amashanyarazi, umuringa unatanga imbaraga za mashini kuri PCB. Uburemere bukwiye bw'umuringa bwongerera imbaraga nigihe kirekire ku kibaho cyumuzunguruko, bikemerera kurwanya kunama, gutitira, cyangwa izindi mpungenge z'umubiri.

3. Gucunga amashyuza:
Umuringa nuyobora ubushyuhe bwiza. Uburemere bwumuringa buhagije bufasha gukwirakwiza neza ubushyuhe butangwa nibice byashyizwe kuri PCB. Ibi birinda guhangayikishwa nubushyuhe cyangwa ibice byananiranye bitewe nubushyuhe bukabije, byemeza kuramba no kwizerwa byubuyobozi.

4. Kurikirana ubugari nubuyobozi bwumwanya:
Uburemere bw'umuringa bugira ingaruka ku bugari no ku murongo utandukanya mugihe cya PCB no gushushanya. Uburemere burebure bw'umuringa busaba ubugari bwagutse n'umwanya kugira ngo bigende neza kandi birinde ubushyuhe bukabije.

Mu gusoza

Muri make,guhitamo uburemere bwumuringa nibyingenzi mugushushanya imikorere-yizewe kandi yizewe PCB.Guhitamo biterwa nibisabwa byihariye bya porogaramu, urebye imikorere y'amashanyarazi, imbaraga za mashini hamwe nubuyobozi bukenewe. Yaba ibikoresho bya elegitoroniki byoroheje byabaguzi cyangwa ingufu zinganda zikoreshwa munganda, uburemere bwumuringa bugira uruhare runini mubikorwa bya PCB kandi bigomba gutekerezwa neza mugice cyateguwe.
