Mu rwego rwa elegitoroniki, imbaho zumuzunguruko zigira uruhare runini muguhuza ibice bitandukanye no gukora neza imikorere yigikoresho. Mu myaka yashize, iterambere mu ikoranabuhanga ryatumye habaho iterambere ryibishushanyo mbonera byumuzunguruko. Imwe muriyo terambere ni itangizwa rya HDI (High Density Interconnect) imbaho zumuzunguruko.Muri iyi nyandiko ya blog, tuzasesengura itandukaniro riri hagati yumuzunguruko wa HDI nu mbaho zisanzwe za PCB (Icapiro ry’umuzunguruko).
Mbere yo gucengera mubirimo byihariye, reka tubanze dusobanukirwe nibanze shingiro ryibibaho byumuzunguruko wa HDI hamwe na PCB.PCB ni isahani iringaniye ikozwe mubikoresho bitayobora hamwe n'inzira ziyobora. Izi nzira, nazo zitwa traces, zifite inshingano zo gutwara ibimenyetso byamashanyarazi hagati yibice bitandukanye kurubaho. Ikibaho cya PCB gikoreshwa cyane mubikoresho bitandukanye bya elegitoroniki, kuva kuri terefone zigendanwa na mudasobwa zigendanwa kugeza ibikoresho byubuvuzi na sisitemu yimodoka.
Ku rundi ruhande, imbaho za HDI, ni verisiyo zigezweho za PCB.Ikoranabuhanga rya HDI ryemerera ubwinshi bwumuzunguruko, imirongo yoroheje, nibikoresho byoroshye. Ibi bifasha kubyara ibikoresho bito bya elegitoronike, byoroshye kandi bikomeye. Ikibaho cyumuzunguruko wa HDI gikoreshwa mubisabwa bisaba umuvuduko mwinshi, gukora neza, hamwe na miniaturizasi, nka terefone zo mu rwego rwo hejuru, tableti, n'ibikoresho byo mu kirere.
Noneho reka turebe itandukaniro riri hagati yumuzunguruko wa HDI nu mbaho zisanzwe za PCB:
Ubucucike bw'umuzunguruko no kugorana:
Ikintu nyamukuru gitandukanya ikibaho cyumuzunguruko wa HDI nubuyobozi busanzwe bwa PCB nubucucike bwumuzingi. Ikibaho cya HDI gifite ubwinshi bwumuzunguruko bitewe nubuhanga buhanitse bwo gukora hamwe namategeko yihariye yo gushushanya. Ugereranije nimbaho gakondo za PCB, ubusanzwe zifite ibice bike, ikibaho cya HDI mubusanzwe gifite ibice byinshi, kuva kuri 4 kugeza kuri 20. Bemerera gukoresha ibice byinyongera na vias ntoya, bigatuma ibice byinshi byinjizwa mumwanya muto. Ku rundi ruhande, imbaho zisanzwe za PCB zigarukira ku gishushanyo cyoroheje cyazo kandi zikaba nkeya, bigatuma ubucucike buri hasi.
Ikoranabuhanga rya Micropore:
Ikibaho cyumuzunguruko wa HDI gikoresha cyane tekinoroji ya microvia, harimo na viasi zimpumyi, vias zashyinguwe hamwe na vias zegeranye. Iyi vias itanga amasano ataziguye hagati yuburyo butandukanye, kugabanya ubuso busabwa kugirango uhindurwe kandi wongere umwanya uhari. Ibinyuranye, imbaho zisanzwe za PCB akenshi zishingiye kubuhanga bwa tekinoroji, bigabanya ubushobozi bwabo bwo kugera kumurongo mwinshi, cyane cyane mubishushanyo mbonera.
Iterambere mu bikoresho:
Ikibaho cyumuzunguruko wa HDI mubisanzwe kirimo ibikoresho bifite ibikoresho byongerewe ubushyuhe, amashanyarazi, nubukanishi. Ibi bikoresho bitanga imikorere inoze, kwizerwa no kuramba, bigatuma imbaho za HDI zibereye gusaba porogaramu. Ikibaho gisanzwe cya PCB, nubwo kigikora, akenshi koresha ibikoresho byibanze kandi ntibishobora kuba byujuje ibyangombwa bikenerwa nibikoresho bya elegitoroniki bigoye.
Miniaturisation:
Ikibaho cyumuzunguruko wa HDI cyashizweho kugirango gikemure miniaturizasi ikenera ibikoresho bya elegitoroniki. Ubuhanga bugezweho bwo gukora bukoreshwa mubibaho bya HDI butuma vias nto (umwobo uhuza ibice bitandukanye) hamwe nibisobanuro byiza. Ibi bivamo ubwinshi bwibigize kuri buri gice, bigafasha gukora ibikoresho bito, byoroshye bitabujije imikorere.
Ubunyangamugayo bwibimenyetso hamwe nihuta ryihuse:
Mugihe icyifuzo cyo kohereza amakuru byihuse hamwe nuburinganire bwibimenyetso bikomeje kwiyongera, imbaho zumuzunguruko wa HDI zitanga inyungu zingenzi kurenza imbaho zisanzwe za PCB. Kugabanuka unyuze hamwe nubunini bwubunini mubibaho bya HDI bigabanya gutakaza ibimenyetso no guhagarika urusaku, bigatuma bikwiranye na progaramu yihuta. Ikoranabuhanga rya HDI ryemerera kandi guhuza ibintu byongeweho nka viasi zihumye kandi zishyinguwe, bikarushaho kunoza imikorere yikimenyetso no kwizerwa.
Igiciro cyo gukora:
Birakwiye ko tumenya ko ikiguzi cyo gukora ibibaho byumuzunguruko wa HDI mubusanzwe kiri hejuru ugereranije nibisanzwe PCB. Ubwiyongere bugoye numubare wibice bituma inzira yo gukora igorana kandi igatwara igihe. Byongeye kandi, gukoresha ibikoresho bigezweho nibikoresho byihariye byiyongera kubiciro rusange. Nyamara, ibyiza nogutezimbere imikorere itangwa nubuyobozi bwa HDI akenshi biruta igiciro cyabyo, cyane cyane munganda aho kwizerwa cyane na miniaturizasi ari ngombwa.
Porogaramu nibyiza:
Gukoresha ikibaho cyumuzunguruko wa HDI:
Ikibaho cya HDI gikoreshwa cyane mubikoresho bya elegitoronike byoroheje nka terefone zigendanwa, tableti, ibikoresho byambarwa, hamwe n’ibikoresho bito byubuvuzi. Ubushobozi bwabo bwo gushyigikira imikorere igezweho no kugabanya ibintu bifatika bituma bikwiranye nibi bikorwa.
Ibyiza byibibaho byumuzunguruko wa HDI:
- Ubucucike bunini bwumuzingi butuma ibintu byinshi bigoye kandi biranga-bishushanyije.
- Kunoza ibimenyetso byuzuye kubera kugabanuka kwa parasitike na inductance.
- Kongera ubushyuhe bukabije butuma imikorere myiza yibikoresho bifite ingufu nyinshi.
- Umwirondoro muto ubika umwanya kandi ushyigikira igishushanyo cyoroheje.
- Kunoza kurwanya ihungabana, kunyeganyega nibidukikije, kuzamura ibikoresho muri rusange.
Muri make,itandukaniro riri hagati yumuzunguruko wa HDI nu mbaho zisanzwe za PCB nini. Ikibaho cyumuzunguruko wa HDI gitanga ubucucike bwumuzunguruko, ubuhanga buhanitse bwo gukora hamwe nibimenyetso byerekana ubunyangamugayo, bigatuma biba byiza cyane, ibikoresho bya elegitoroniki byoroshye. Ariko, imbaho zisanzwe za PCB zirashobora kandi gukora mubisabwa bidasaba ibintu bigoye cyangwa miniaturizasi. Gusobanukirwa itandukaniro bizafasha abashushanya nababikora guhitamo ikibaho cyumuzunguruko gikenewe kubyo bakeneye byihariye, kwemeza imikorere myiza, kwizerwa no gukora kubikoresho byabo bya elegitoroniki.
