Kuzamura ibihimbano bya PCB: hitamo kurangiza neza kubibaho byawe 12

Muri iyi blog, tuzaganira kubuvuzi bukunzwe cyane ninyungu zabo kugirango bigufashe kuzamura uburyo bwawe bwo guhimba PCB-12.

Mu rwego rwumuzunguruko wa elegitoronike, imbaho ​​zicapye zicapye (PCBs) zifite uruhare runini muguhuza no guha ingufu ibikoresho bitandukanye bya elegitoroniki. Mugihe ikoranabuhanga ritera imbere, ibyifuzo bya PCB byateye imbere kandi bigoye byiyongera cyane. Kubwibyo, gukora PCB byahindutse intambwe ikomeye mugukora ibikoresho bya elegitoroniki byujuje ubuziranenge.

Ikintu cyingenzi ugomba gusuzuma mugihe cyo gukora PCB ni ugutegura hejuru.Kuvura isura bivuga igifuniko cyangwa kurangiza bikoreshwa kuri PCB kugirango birinde ibintu bidukikije kandi byongere imikorere yacyo. Hariho uburyo butandukanye bwo kuvura hejuru burahari, kandi guhitamo uburyo bwiza bwo kuvura ikibaho cyawe 12 birashobora kugira ingaruka zikomeye kumikorere no kwizerwa.

1.HASL (kugurisha ikirere gishyushye kuringaniza):
HASL nuburyo bukoreshwa cyane muburyo bwo kuvura burimo kwibiza PCB mugurisha gushonga hanyuma ugakoresha icyuma gishyushye kugirango ukureho uwagurishije birenze. Ubu buryo butanga igisubizo cyigiciro hamwe nibishobora kugurishwa. Ariko, ifite aho igarukira. Umugurisha ntashobora kugabanwa neza hejuru, bikavamo kurangiza kutaringaniye. Byongeye kandi, ubushyuhe bwinshi bugaragara mugihe cyibikorwa birashobora gutera impagarara zumuriro kuri PCB, bikagira ingaruka kubwizerwa.

2. ENIG (zahabu idafite amashanyarazi ya nikel):
ENIG ni amahitamo azwi cyane yo kuvura hejuru kubera gusudira kwiza kandi neza. Mubikorwa bya ENIG, urwego ruto rwa nikel rushyirwa hejuru yumuringa, hagakurikiraho urwego ruto rwa zahabu. Ubu buvuzi butuma okiside irwanya kandi ikarinda umuringa kwangirika. Byongeye kandi, isaranganya rimwe rya zahabu hejuru yubuso ritanga ubuso buringaniye kandi bworoshye, bigatuma bikwiranye nibice byiza. Ariko, ENIG ntabwo isabwa kubisabwa byinshyi nyinshi kubera gutakaza ibimenyetso bishobora guterwa na nikel barrière.

3. OSP (organic solderability preservative):
OSP nuburyo bwo kuvura hejuru burimo gukoresha urwego ruto rworoshye kurwego rwumuringa binyuze mumiti. OSP itanga igisubizo cyiza kandi cyangiza ibidukikije kuko idasaba ibyuma biremereye. Itanga ubuso bunoze kandi bworoshye butanga kugurishwa neza. Nyamara, impuzu za OSP zumva neza ubushuhe kandi zisaba uburyo bukwiye bwo kubika kugirango zigumane ubusugire bwazo. Ikibaho cyavuwe na OSP nacyo gishobora kwibasirwa cyane no gukemura ibyangiritse kuruta ubundi buvuzi bwo hejuru.

4. Ifeza yo kwibiza:
Ifeza ya Immersion, izwi kandi nka silver immersion, ni amahitamo azwi cyane kuri PCBs nyinshi cyane kubera ubushobozi bwayo bwiza no gutakaza kwinjiza bike. Itanga ubuso buringaniye, buringaniye bwemeza kugurishwa kwizewe. Ifeza yo kwibiza ifitiye akamaro kanini PCBs hamwe nibice byiza hamwe nibisabwa byihuse. Nyamara, isura ya feza ikunda kwanduza ibidukikije kandi bisaba gufata neza no kubika kugirango ubungabunge ubusugire bwabyo.

5. Isahani ikomeye ya zahabu:
Isahani ikomeye ya zahabu ikubiyemo gushyira igice kinini cya zahabu hejuru yumuringa binyuze mumashanyarazi. Ubu buryo bwo kuvura butanga amashanyarazi meza cyane hamwe no kurwanya ruswa, bigatuma bukoreshwa mubisabwa bisaba kwinjiza inshuro nyinshi no kuvanaho ibice. Isahani ikomeye ya zahabu isanzwe ikoreshwa kumurongo uhuza no guhinduranya. Nyamara, ikiguzi cyiyi miti ni kinini ugereranije nubundi buryo bwo kuvura.

Muri make, guhitamo ubuso bwuzuye kurangiza kuri 12-PCB ni ngombwa kubikorwa byayo no kwizerwa.Buri buryo bwo kuvura hejuru bufite ibyiza nimbibi, kandi guhitamo biterwa nibisabwa byihariye na bije. Waba wahisemo gutera amabati meza cyane, zahabu yo kwibiza yizewe, ibidukikije byangiza ibidukikije, ifeza yibiza cyane, cyangwa isahani ikomeye ya zahabu, gusobanukirwa inyungu nibitekerezo kuri buri muti bizagufasha kuzamura inzira yo gukora PCB kandi urebe neza ko uzatsinda ibikoresho bya elegitoroniki.
