Ikibaho cya PCB (Printedcircuitboard) ni cyo gishyigikira ibice by'ikoranabuhanga kandi ni cyo gihuza ibice by'ikoranabuhanga n'ibice by'amashanyarazi. Ni hafi ya byose, ni ibikorwa remezo by'ibikoresho byose bifite ubwenge. Uretse imirimo y'ibanze yo gusana ibice bito bitandukanye by'ikoranabuhanga, inshingano y'ingenzi ni uguhuza ibice by'ikoranabuhanga byavuzwe haruguru.
Ni ibihe bice bigize ikibaho cya PCB?
Ikibaho cya PCB gigizwe ahanini n'udupira two gusudira, umwobo unyuramo, umwobo wo gushyiramo, insinga, ibice, imiyoboro, kuzuza, imipaka y'amashanyarazi n'ibindi.
(1) Padi: umwobo w'icyuma ukoreshwa mu gusudira imigozi y'ibice.
(2) Mu myobo: hari icyuma kinyura mu myobo n'ibitari icyuma kinyura mu myobo, aho icyuma kinyura mu myobo gikoreshwa mu guhuza imigozi y'ibice biri hagati ya buri cyiciro.
(3) Umwobo wo gushyiramo: ukoreshwa mu gusana ikibaho cy'uruziga.
(4) Kondukteri: icyuma cy'amashanyarazi gikoreshwa mu guhuza imigozi y'ibice.
(5) Ibihuza: ibice bikoreshwa mu guhuza ibibaho by'uruziga.
(6) Kuzuza: gukoresha umuringa mu muyoboro w'insinga zo hasi bishobora kugabanya neza impedance.
(7) Umupaka w'amashanyarazi: ukoreshwa mu kugena ingano y'ikibaho cy'uruziga, ibice by'ikibaho ntibishobora kurenza umupaka.
Ukurikije imiterere y'urubaho rwa PCB, rushobora kugabanywamo ibice bibiri bya PCB, PCB ifite ibice bibiri, PCB ifite ibice byinshi; Urundi ruhande rusanzwe rufite ibice bine, rufite ibice bitandatu, PCB ifite ibice byinshi ishobora kugera ku bice birenga icumi.
Uko amashami menshi ya PCB arushaho kuba menshi, ni ko amashanyarazi arushaho gukomera kandi yizewe, kandi igiciro kikaba kinini. Itandukaniro ry'ibiciro bya paneli imwe n'iy'ibice bibiri ntabwo ari rinini. Iyo nta byangombwa byihariye bihari, inganda zose zizahitamo paneli ebyiri. N'ubundi kandi, imikorere n'ubudahangarwa bya paneli ebyiri ni byiza kuruta ibya paneli imwe.
Muri PCB multilayer board, ubu inganda ni zo zikoreshwa cyane cyangwa enye, esheshatu, inganda zikoresha ibikoresho by'ikoranabuhanga zifite PCB board yo ku rwego rwo hejuru ni nyinshi. Nubwo multilayer panels zifite ibyiza byinshi kurusha two panels mu mikorere, ituze, urusaku n'ibindi bintu, ibigo byinshi n'abahanga baracyakunda two panels kugira ngo bahabwe ikiguzi.
Uko ibikoresho by'ubwenge bigenda birushaho kuba ingorabahizi, ni ko hakenewe ibikoresho byinshi, bigatuma habaho circuits n'ibindi bikoresho bito kuri PCB. Muri icyo gihe, ibisabwa ku bwiza bw'ibihuza PCB nabyo birarushaho kunozwa. PCB board nto ntishobora kugabanya ikiguzi gusa, ahubwo ishobora no koroshya imiterere y'ikibaho cya PCB, ku buryo igihombo cy'ikimenyetso cyo kohereza circuit kiba gito.
Igihuza cy’urubaho rwa PCB gifite ingufu nyinshi ni ingano y’agatsinsino gusa, kandi icyuma gihuza gikozwe mu muringa utukura gikozwe mu ifeza, ibyo bikaba birushaho kunoza imikorere y’urubaho. Ndetse n’urubaho ruto rushobora kugira ingufu nyinshi, bigatuma urubaho rukora neza, kandi uburyo butandukanye bwo gushyiraho bushobora guhaza ibyifuzo by’abakiriya batandukanye ba PCB.
Amass ifite uburebure butandukanye bw'ibihuza ibyuma bya PCB bifite ubugari butandukanye, bihuye n'ibipimo ngenderwaho by'inganda by'ubugari bwa 1.0-1.6mm kugira ngo ibikoresho bikoreshwe neza!
