Muri iyi blog, tuzaganira ku buhanga busanzwe bwo kugurisha bukoreshwa mu nteko ya PCB igoye nuburyo butezimbere muri rusange kwizerwa n’imikorere yibi bikoresho bya elegitoroniki.
Tekinoroji yo kugurisha igira uruhare runini mugikorwa cyo guterana kwa PCB igoye. Izi mbaho zidasanzwe zagenewe gutanga uruvange rwo gukomera no guhinduka, bigatuma biba byiza kubikorwa bitandukanye aho umwanya ari muto cyangwa guhuza imiyoboro isabwa.
1. Ubuso bwa tekinoroji yububiko (SMT) mubikorwa bikomeye bya PCB:
Ikoranabuhanga rya Surface mount (SMT) nimwe muburyo bukoreshwa cyane bwo kugurisha mugiterane gikomeye cya PCB. Tekinike ikubiyemo gushyira ibice byubuso hejuru kubibaho no gukoresha paste yo kugurisha kugirango ubifate mumwanya. Solder paste irimo uduce duto two kugurisha twahagaritswe muri flux ifasha mugikorwa cyo kugurisha.
SMT ituma ibice byinshi byuzuzanya, bigatuma umubare munini wibigize ushyirwa kumpande zombi za PCB. Ikoranabuhanga ritanga kandi imikorere yubushyuhe n amashanyarazi bitewe ninzira ngufi ziyobora zakozwe hagati yibigize. Ariko, birasaba kugenzura neza inzira yo gusudira kugirango wirinde ibiraro byabagurisha cyangwa ingingo zidandaza zidahagije.
2. Binyuze mu buhanga bwa tekinoroji (THT) muburyo bukomeye bwa PCB:
Mugihe ibice byo hejuru byububiko bikoreshwa mubisanzwe PCBs, ibice byanyuze mu mwobo nabyo birasabwa mubihe bimwe. Binyuze mu mwobo (THT) bikubiyemo kwinjiza ibice biganisha mu mwobo kuri PCB no kubigurisha kurundi ruhande.
THT itanga imbaraga za mashini kuri PCB kandi ikongerera imbaraga zo guhangayikishwa no guhindagurika. Yemerera kwishyiriraho umutekano ibice binini, biremereye bishobora kuba bidakwiriye SMT. Nyamara, THT itanga inzira ndende kandi irashobora kugabanya PCB guhinduka. Kubwibyo, ni ngombwa guhuza ibipimo hagati ya SMT na THT muburyo bukomeye bwa PCB.
3. Kuringaniza ikirere gishyushye (HAL) muburyo bukomeye bwa PCB gukora:
Kuringaniza ikirere gishyushye (HAL) nubuhanga bwo kugurisha bukoreshwa mugukoresha igipande kimwe cyabacuruzi kugirango bagaragaze ibimenyetso byumuringa kuri PCBs ikomeye. Tekinike ikubiyemo kunyuza PCB mu bwogero bwabacuruzi bashongeshejwe hanyuma ukayishyira mu kirere gishyushye, ifasha gukuramo ibicuruzwa birenze kandi bigakora ubuso bunini.
HAL ikoreshwa kenshi kugirango igenzurwe neza ryumuringa wagaragaye no gutanga igikingira kirinda okiside. Itanga ibicuruzwa byiza muri rusange kandi igateza imbere kugurisha hamwe. Nyamara, HAL ntishobora kuba ibereye kubishushanyo mbonera bya PCB bigoye cyane cyane bifite ibizunguruka neza cyangwa bigoye.
4. Gusudira guhitamo muburyo bukomeye PCB itanga:
Kugurisha byatoranijwe ni tekinike ikoreshwa muguhitamo kugurisha ibice byihariye kuri PCBs ikomeye. Ubu buhanga bukubiyemo gukoresha icyuma cyo kugurisha cyangwa kugurisha ibyuma kugirango ushyire muburyo bugurisha ahantu runaka cyangwa ibice kuri PCB.
Kugurisha byatoranijwe ni ingirakamaro cyane mugihe hari ibice byangiza ubushyuhe, umuhuza, cyangwa ahantu hacucitse cyane bidashobora kwihanganira ubushyuhe bwinshi bwo kugurisha ibintu. Iremera kugenzura neza uburyo bwo gusudira kandi bigabanya ibyago byo kwangiza ibice byoroshye. Ariko, kugurisha guhitamo bisaba gushiraho no gutangiza gahunda ugereranije nubundi buhanga.
Mu ncamake, tekinoroji ikoreshwa cyane yo gusudira kubiterane bikomatanyije birimo tekinoroji yo hejuru yubuso (SMT), hifashishijwe ikoranabuhanga (THT), kuringaniza ikirere gishyushye (HAL) hamwe no gusudira guhitamo.Buri tekinoroji ifite ibyiza byayo nibitekerezo, kandi guhitamo biterwa nibisabwa byihariye byubushakashatsi bwa PCB. Mugusobanukirwa tekinoloji ningaruka zabyo, abayikora barashobora kwemeza kwizerwa no gukora bya PCBs bigoye cyane mubikorwa bitandukanye.
