Muri make, PCB yambaye ubusa yerekeza ku kibaho cyumuzingo cyacapwe nta na kimwe kinyuze mu mwobo cyangwa ibikoresho bya elegitoroniki. Bakunze kwitwa PCB yambaye ubusa kandi rimwe na rimwe nanone bita PCBs. Ikibaho cyubusa PCB gifite imiyoboro yibanze gusa, imiterere, gutwikira ibyuma na substrate ya PCB.

Ni ubuhe buryo bwo gukoresha ikibaho cya PCB cyambaye ubusa?
PCB yambaye ubusa ni skeleton yubuyobozi bwa gakondo. Iyobora ibigezweho nubu bigezweho binyuze munzira ziboneye kandi ikoreshwa mubikoresho byinshi bya mudasobwa.

Ubworoherane bwa PCB yubusa itanga injeniyeri nabashushanya ubwisanzure buhagije bwo kongeramo ibice nkuko bikenewe. Ikibaho cyambaye ubusa gitanga ibintu byoroshye kandi bigatanga umusaruro mwinshi.

Ubu buyobozi bwa PCB busaba akazi ko gushushanya kuruta ubundi buryo bwo gukoresha insinga, ariko burashobora guhita bwikora nyuma yo guterana no gukora. Ibi bituma PCB ikibaho ihendutse kandi nziza.

Ikibaho cyambaye ubusa ni ingirakamaro nyuma yo kongeramo ibice. Intego nyamukuru ya PCB yambaye ubusa nuguhinduka ikibaho cyuzuye cyumuzunguruko. Niba bihujwe nibigize bikwiye, bizakoreshwa byinshi.

Ariko, ntabwo aribwo buryo bwonyine bwo gukoresha imbaho ​​za PCB zambaye ubusa. Blank PCB nicyiciro cyiza cyo gukora ibizamini byambaye ubusa muburyo bwo gukora ibizunguruka. Ni ngombwa gukumira ibibazo byinshi bishobora kubaho mugihe kizaza.
Kuki kwipimisha ubusa?
Hariho impamvu nyinshi zo kugerageza imbaho ​​zambaye ubusa. Nkikibaho cyumuzunguruko, kunanirwa kwa PCB nyuma yo kwishyiriraho bizatera ibibazo byinshi.

Nubwo bidasanzwe, PCB yambaye ubusa irashobora kuba ifite inenge mbere yo kongeramo ibice. Ibibazo bikunze kugaragara ni ukurenza urugero, munsi-gutobora no gutobora. Ndetse inenge ntoya irashobora gutera kunanirwa gukora.

Bitewe no kwiyongera k'ubucucike bwibigize, icyifuzo cyibibaho byinshi PCB bikomeje kwiyongera, bigatuma ibizamini byambaye ubusa ari ngombwa. Nyuma yo guteranya PCB igizwe nabantu benshi, iyo habaye kunanirwa, ntibishoboka kuyisana.

Niba PCB yambaye ubusa ari skeleton yinama yumuzunguruko, ibigize ni ingingo n'imitsi. Ibigize birashobora kuba bihenze cyane kandi akenshi birakomeye, kubwigihe kirekire, kugira ikadiri ikomeye birashobora kubuza ibice byohejuru guta.

Ubwoko bwikizamini cyambaye ubusa
Nigute ushobora kumenya niba PCB yangiritse?
Ibi bigomba kugeragezwa muburyo bubiri butandukanye: amashanyarazi no kurwanya.
Ikizamini cyambaye ubusa cyerekana kandi kwigunga no gukomeza guhuza amashanyarazi. Ikizamini cyo kwigunga gipima isano iri hagati yuburyo bubiri butandukanye, mugihe ikizamini cyo gukomeza kugenzura kugirango harebwe ko nta ngingo zifunguye zishobora kubangamira ikigezweho.
Nubwo ibizamini byamashanyarazi ari ibisanzwe, ibizamini byo kurwanya ntibisanzwe. Ibigo bimwe bizakoresha guhuza byombi, aho gukoresha buhumyi ikizamini kimwe.
Igeragezwa rya Resistance ryohereza amashanyarazi binyuze mumashanyarazi kugirango apime irwanya umuvuduko. Ihuza rirerire cyangwa ryoroshye rizabyara imbaraga nyinshi kuruta guhuza bigufi cyangwa binini.
Ikizamini
Kubicuruzwa bifite igipimo runaka cyumushinga, abakora imbaho ​​zicapye zumuzunguruko bazakoresha ibikoresho byagenwe mugupima, bita "test racks." Iki kizamini gikoresha amapine yuzuye amasoko kugirango agerageze ubuso bwose kuri PCB.
Ikizamini gihamye gikora neza kandi kirashobora kurangira mumasegonda make. Ingaruka nyamukuru nigiciro kinini no kubura guhinduka. Ibishushanyo bitandukanye bya PCB bisaba ibikoresho bitandukanye (bikwiranye nibikorwa byinshi).
Ikizamini cya prototype
Ikizamini cyo kuguruka gikoreshwa muri rusange. Intwaro ebyiri za robo zifite inkoni zikoresha porogaramu ya software kugirango igerageze guhuza ikibaho.
Ugereranije nikigereranyo gihamye, bifata igihe kirekire, ariko birashoboka kandi byoroshye. Kugerageza ibishushanyo bitandukanye biroroshye nko kohereza dosiye nshya.

Inyungu zo kwipimisha ubusa
Ikizamini cyibibaho gifite ibyiza byinshi, nta ngaruka zikomeye. Iyi ntambwe mubikorwa byo gukora irashobora kwirinda ibibazo byinshi. Umubare muto w'ishoramari ryambere urashobora kuzigama amafaranga menshi yo kubungabunga no gusimbuza.

Kwipimisha ikibaho bifasha kubona ibibazo hakiri kare mubikorwa byo gukora. Kubona ikibazo hakiri kare bisobanura gushaka intandaro yikibazo no kubasha gukemura ikibazo mumuzi yacyo.

Niba ikibazo kivumbuwe muburyo bukurikira, bizagorana kubona ikibazo cyumuzi. Ubuyobozi bwa PCB bumaze gutwikirwa nibigize, ntibishoboka kumenya icyateye ikibazo. Kwipimisha hakiri kare bifasha gukemura ikibazo cyintandaro.

Kwipimisha nabyo byoroshya inzira yose. Niba ibibazo byavumbuwe bigakemurwa mugihe cyiterambere rya prototype, ibyiciro byumusaruro bizakurikiraho birashobora gukomeza nta nkomyi.

Bika igihe cyumushinga ukoresheje ibizamini byambaye ubusa

Nyuma yo kumenya ikibaho cyambaye ubusa, no gusobanukirwa n'akamaro ko kwipimisha ubusa. Uzasanga nubwo inzira yambere yumushinga iba gahoro gahoro kubera kwipimisha, umwanya wabitswe no kwipimisha ubusa kubushakashatsi kumushinga urenze kure igihe gitwara. Kumenya niba hari amakosa muri PCB birashobora gutuma ibibazo byakurikiraho byoroshye.

Icyiciro cyambere nicyo gihe cyigiciro cyinshi cyo kwipimisha ubusa. Niba ikibaho cyumuzunguruko cyananiranye ukaba ushaka kugisana ahabigenewe, ikiguzi cyigihombo gishobora kuba inshuro magana.

Iyo substrate imaze kugira ikibazo, amahirwe yo kuyacika azamuka cyane. Niba ibice bihenze byagurishijwe kuri PCB, igihombo kiziyongera. Kubwibyo, nibibi cyane kubona amakosa nyuma yinama yumuzunguruko. Ibibazo byavumbuwe muriki gihe mubisanzwe biganisha ku gusiba ibicuruzwa byose.

Hamwe no kunoza imikorere nukuri gutangwa nikizamini, birakwiye ko ukora ibizamini byambaye ubusa mugihe cyambere cyo gukora. Nyuma ya byose, niba ikibaho cyanyuma cyumuzunguruko cyananiranye, ibihumbi nibice bishobora guta.
