Uburyo 7 busanzwe bwo kumenya ubuyobozi bwa PCB kugirango dusangire

Uburyo busanzwe bwo gutahura ubuyobozi bwa PCB nuburyo bukurikira:

1, Ubuyobozi bwa PCB intoki kugenzura

Ukoresheje ikirahure kinini cyangwa microscope ya Calibrated, igenzurwa ryumukoresha nuburyo busanzwe bwo kugenzura kugirango hamenyekane niba ikibaho cyumuzunguruko gihuye nigihe gikenewe cyo gukosora. Ibyiza byingenzi byingenzi ni ibiciro biri imbere kandi nta kizamini kiriho, mugihe ibibi byingenzi byingenzi ari amakosa yibintu byabantu, ikiguzi cyigihe kirekire, gutahura inenge zidahagarara, ingorane zo gukusanya amakuru, nibindi. Kugeza ubu, kubera ubwiyongere bwumusaruro wa PCB, kugabanuka intera y'insinga hamwe nubunini bwibigize kuri PCB, ubu buryo buragenda burushaho kuba bwiza.

2, Ikizamini cya PCB kumurongo

Binyuze mu gutahura ibintu byamashanyarazi kugirango umenye inenge zogukora no kugereranya ibigereranyo, ibyuma bya digitale hamwe nuruvange rwibimenyetso byerekana ko byujuje ibisobanuro, hariho uburyo bwinshi bwo kwipimisha nko gupima inshinge no gupima urushinge. Ibyiza byingenzi nigiciro gito cyo kwipimisha kuri buri kibaho, imbaraga zikomeye za digitale nubushobozi bwo gupima, byihuse kandi byuzuye bigufi kandi bifungura ibizamini byumuzunguruko, porogaramu ikora porogaramu, gukwirakwiza inenge nyinshi no koroshya gahunda. Ingaruka nyamukuru nugukenera kugerageza clamp, programing nigihe cyo gukemura, ikiguzi cyo gukora fixture ni kinini, kandi ingorane zo gukoresha ni nini.

3, ikizamini cyibikorwa bya PCB

Ikizamini cya sisitemu y'imikorere ni ugukoresha ibikoresho byihariye byo kwipimisha mugice cyo hagati no kurangiza umurongo wibyakozwe kugirango ukore ikizamini cyuzuye cyimikorere yimikorere yumuzunguruko kugirango hemezwe ubuziranenge bwumuzunguruko. Kwipimisha kumikorere birashobora kuvugwa ko aribwo buryo bwambere bwo kugerageza bwikora, bushingiye ku kibaho runaka cyangwa igice runaka kandi gishobora kurangizwa nibikoresho bitandukanye. Hariho ubwoko bwibizamini byanyuma, icyitegererezo giheruka, hamwe no kugerageza. Igeragezwa ryimikorere mubisanzwe ntabwo ritanga amakuru yimbitse nka pin hamwe nibice byo gusuzuma urwego rwo guhindura imikorere, kandi bisaba ibikoresho kabuhariwe hamwe nuburyo bwihariye bwo gukora ibizamini. Kwandika uburyo bwo gukora ibizamini biragoye kandi ntibikwiriye kumirongo myinshi yububiko.

4, gushakisha byikora

Bizwi kandi nk'igenzura ryikora ryikora, rishingiye ku ihame rya optique, gukoresha mu buryo bwuzuye isesengura ry’amashusho, mudasobwa no kugenzura byikora hamwe n’ikoranabuhanga rindi, inenge zagaragaye mu musaruro wo gutahura no gutunganya, ni uburyo bushya bwo kwemeza inenge zakozwe. Ubusanzwe AOI ikoreshwa mbere na nyuma yo kugaruka, mbere yo gupima amashanyarazi, kugirango igabanye igipimo cyo kwemerwa mugihe cyo kuvura amashanyarazi cyangwa icyiciro cyo gupima imikorere, mugihe ikiguzi cyo gukosora inenge kiri munsi yikiguzi nyuma yikizamini cya nyuma, akenshi kigera ku nshuro icumi.

5, ikizamini cya X-cyikora

Dukoresheje uburyo butandukanye bwo kwinjiza ibintu bitandukanye kuri X-ray, dushobora kubona binyuze mubice bigomba gutahurwa no kubona inenge. Ikoreshwa cyane cyane mugutahura ikibanza cyiza cyane nububiko bwumuzunguruko wa ultra-high density hamwe nudusembwa nkikiraro, chip yatakaye hamwe no kudahuza neza byakozwe mugiterane, kandi birashobora no gutahura inenge zimbere za chip za IC ukoresheje tekinoroji ya tomografi. Ubu ni bwo buryo bwonyine bwo kugerageza gusudira ubuziranenge bwumupira wa gride array hamwe namabati akingiwe. Ibyiza byingenzi nubushobozi bwo kumenya BGA gusudira ubuziranenge hamwe nibikoresho byashyizwemo, nta giciro cyimikorere; Ingaruka nyamukuru ni umuvuduko mwinshi, umuvuduko mwinshi wo kunanirwa, ingorane zo kumenya ingingo zagurishijwe zakozwe, igiciro kinini, nigihe kinini cyo gutegura gahunda, nuburyo bushya bwo gutahura kandi bugomba gukomeza kwigwa.

6, sisitemu yo kumenya laser

Niterambere rigezweho muburyo bwa tekinoroji yo gupima PCB. Ikoresha urumuri rwa lazeri kugirango rusuzume ikibaho cyacapwe, ikusanya amakuru yose yo gupimwa, kandi igereranye agaciro nyako ko gupimwa hamwe nagaciro kagenwe ntarengwa. Iri koranabuhanga ryagaragaye ku byapa byoroheje, birasuzumwa mu gupima ibyapa, kandi byihuta bihagije ku murongo rusange. Ibisohoka byihuse, nta fixture isabwa hamwe no kutabona maskike nibyiza byingenzi; Igiciro cyambere cyambere, kubungabunga no gukoresha ibibazo nibitagenda neza.

7, kumenya ingano

Ibipimo byumwobo, uburebure n'ubugari, hamwe na dogere ya dogere bipimwa nigikoresho cyo gupima ishusho ya quadratic. Kubera ko PCB ari ubwoko buto, bworoshye kandi bworoshye bwibicuruzwa, gupima guhuza biroroshye kubyara deformasiyo, bikavamo gupimwa nabi, kandi igikoresho cyo gupima amashusho abiri-cyabaye igikoresho cyiza cyo gupima neza. Igikoresho cyo gupima amashusho yo gupima Sirui kimaze gutegurwa, kirashobora gutahura ibipimo byikora, bidafite gusa ibipimo bihanitse byo gupima, ariko kandi bigabanya cyane igihe cyo gupima no kunoza imikorere yo gupima.
