NIKI CYIZA CY'UMUPIRA W'UMUCURUZI?

Umupira ugurisha ni imwe mu nenge zikunze kugaragara ziboneka mugihe ukoresheje tekinoroji yo hejuru yubuso ku kibaho cyacapwe. Nukuri kwizina ryabo, ni umupira wumugurisha watandukanije numubiri nyamukuru ugize ibice bifatanyirijwe hamwe hejuru yibibaho.

Imipira yagurishijwe ni ibikoresho bitwara, bivuze ko iyo izungurutse ku kibaho cyacapwe, gishobora gutera ikabutura y'amashanyarazi, bikagira ingaruka mbi ku kwizerwa kw'ikibaho cyacapwe.

KuriIPC-A-610, PCB ifite imipira irenga 5 yagurishijwe (<= 0.13mm) muri 600mm² ifite inenge, kuko diameter irenze 0.13mm irenga ku ihame ntarengwa ryo gukuraho amashanyarazi. Nubwo, nubwo aya mategeko avuga ko imipira yabagurisha ishobora gusigara idahwitse iyo ifatanye neza, ntaburyo nyabwo bwo kumenya neza niba aribyo.

UBURYO BWO GUKosora UMUPIRA W'UMUCURUZI MBERE YUKO

Imipira igurishwa irashobora guterwa nimpamvu zitandukanye, bigatuma gusuzuma ikibazo runaka bitoroshye. Rimwe na rimwe, birashobora kuba ibintu bidasanzwe. Hano hari zimwe mumpamvu zisanzwe zigurisha imipira yo kugurisha muburyo bwa PCB.

Ubushuhe-Ubushuheyarushijeho kuba kimwe mubibazo bikomeye kubacapyi bayobora imashanyarazi muri iki gihe. Usibye ingaruka za popcorn hamwe no guturika kwa microscopique, birashobora kandi gutuma imipira yabagurisha ibaho kubera guhunga umwuka cyangwa amazi. Menya neza ko imbaho ​​zicapye zumye zumye neza mbere yo kugurisha, cyangwa gukora impinduka kugirango ugabanye ubushuhe mubidukikije.

Solder Paste- Ibibazo biri mubigurisha ubwabyo birashobora kugira uruhare mugushinga imipira yabagurisha. Kubwibyo, ntabwo bisabwa kongera gukoresha paste yo kugurisha cyangwa kwemerera ikoreshwa rya paste yagurishijwe kurenza itariki izarangiriraho. Solder paste nayo igomba kubikwa neza kandi igakorwa kumurongo ngenderwaho wuwabikoze. Amazi meza yo kugurisha paste arashobora kandi kugira uruhare mubushuhe burenze.

Igishushanyo mbonera- Umupira wo kugurisha urashobora kubaho mugihe ikaramu yasukuwe nabi, cyangwa mugihe ikaramu yanditse nabi. Rero, kwiringira aninararibonye yacapwe yumuzungurukon'inzu y'iteraniro irashobora kugufasha kwirinda aya makosa.

Kugaragaza Umwirondoro w'Ubushyuhe- Flex solvent ikeneye guhinduka ku kigero gikwiye. A.hejurucyangwa igipimo cyabanjirije ubushyuhe gishobora kuganisha kumupira wo kugurisha. Kugira ngo iki kibazo gikemuke, menya neza ko kuzamuka kwawe kutageze kuri 1.5 ° C / amasegonda kuva mucyumba cyo hejuru cy’icyumba kugeza kuri 150 ° C.

GUKURAHO UMUPIRA W'UMUCURUZI

Sasa muri sisitemu zo mu kirerenuburyo bwiza bwo gukuraho umupira wagurishijwe. Izi mashini zikoresha umuyaga mwinshi wumuyaga ukuraho imipira yabagurisha hejuru yikibaho cyumuzingo wacapwe bitewe numuvuduko mwinshi.

Nyamara, ubu bwoko bwo kuvanaho ntabwo bukora neza mugihe intandaro yaturutse kuri PCB zanditse nabi hamwe nibibazo byabanjirije kugurisha ibicuruzwa.

Nkigisubizo, nibyiza gusuzuma icyateye imipira yabagurisha hakiri kare bishoboka, kuko izi nzira zirashobora kugira ingaruka mbi mubikorwa bya PCB nibikorwa byawe. Kwirinda bitanga ibisubizo byiza.

SHAKA INGARUKA NA IMAGINEERING INC

Kuri Imagineering, twumva ko uburambe aribwo buryo bwiza bwo kwirinda hiccups izana no guhimba PCB no guterana. Dutanga ubuziranenge-mubyiciro byizewe mubikorwa bya gisirikari no mu kirere, kandi dutanga impinduka byihuse kuri prototyping n'umusaruro.
