Itandukaniro rikomeye riri hagati ya HDI na PCB isanzwe - igihe gishya cyo guhuza imiyoboro y'amashanyarazi ifite ubucucike bwinshi
HDI (Ubucucike Bunini) ni ikibaho gito cyagenewe abakoresha ikoranabuhanga riciriritse. Ugereranyije na PCB zisanzwe, ikintu cy'ingenzi cya HDI ni ubucucike bwayo bwinshi bw'insinga. Itandukaniro riri hagati y'ibyo byombi rigaragarira ahanini mu ngingo enye zikurikira.
1.HDI ni nto kandi yoroheje mu buremere
Imbuga za HDI zikozwe mu mbaho gakondo zifite impande ebyiri nk'imbaho z'ibanze kandi zishyirwamo lamination ihoraho. Ubwo bwoko bw'imbaho za circuit zikozwe muri lamination ihoraho bwitwa kandi Build-up Multilayer board (BUM). Ugereranyije n'imbaho za circuit zisanzwe, HDI zifite ibyiza byo kuba "zoroshye, nto, ngufi, kandi ntoya".
Imikoranire y'amashanyarazi hagati y'ibice by'imbaho bya HDI ikorwa binyuze mu mwobo uyobora, uhishwe/udafunguye binyuze mu miyoboro. Imiterere yayo itandukanye n'ibice bisanzwe by'imbaho bifite ibice byinshi. Umubare munini w'ibice bitwikiriwe/bidafunguye bikoreshwa mu bice bya HDI. HDI ikoresha imiyoboro ikoresha laser, mu gihe PCB isanzwe ikoresha imiyoboro ikoresha ikoranabuhanga, bityo umubare w'ibice n'ikigereranyo cy'ibice bikunze kugabanuka.
2. Uburyo bwo gukora motherboard ya HDI
Ubucucike bwinshi bw'imbaho za HDI bugaragarira ahanini mu bucucike bw'imyobo, imirongo, udupapuro, n'ubugari bw'ibice bihuza.
Umwobo muto: Imbuga ya HDI irimo imiterere y’umwobo muto nka blind via, igaragara cyane cyane mu ikoranabuhanga ryo gukora umwobo muto ufite umurambararo uri munsi ya 150um hamwe n’ibisabwa byinshi mu bijyanye n’ikiguzi, imikorere myiza n’igenzura ry’aho umwobo uherereye. Hariho umwobo unyura gusa mu mbaho gakondo zifite urwego rwinshi kandi nta mbuga nto zihishe cyangwa zidafite blind zihari.
Kunoza ubugari/intera y'umurongo: Ibi bigaragarira cyane cyane mu bisabwa bikomeye ku birebana n'inenge z'umurongo n'ubuso bw'umurongo. Muri rusange, ubugari/intera y'umurongo ntigomba kurenza 76.2um.
Ubucucike bwinshi bw'amapine: ubucucike bw'aho ushyiramo soldering burenze 50/cm2
Kugabanya ubugari bwa dielectric: Ibi bigaragarira cyane cyane mu buryo ubugari bwa dielectric hagati y’urwego rumwe bugera kuri 80um no munsi yarwo, kandi ibisabwa kugira ngo ubugari bube bumwe birarushaho gukomera, cyane cyane ku mbaho zifite ubucucike bwinshi n’ibikoresho byo gupakira bifite uburyo bwo kugenzura impedance.
3. Imikorere y'amashanyarazi ya HDI board irushaho kuba myiza
HDI ntituma gusa imiterere y'ibicuruzwa bya nyuma iba ntoya cyane, ahubwo inahuza n'ibipimo byo hejuru by'imikorere n'imikorere y'ikoranabuhanga.
Ubucucike bw'amakuru ya HDI bwiyongera butuma habaho imbaraga z'amakuru kandi bukongera ubwizerwe. Byongeye kandi, amabati ya HDI afite iterambere ryiza mu bijyanye no kubangamira RF, kubangamira umuraba wa electromagnetic, kugabanya umuriro wa electrostatic, gutwara ubushyuhe, nibindi. HDI ikoresha kandi ikoranabuhanga ryuzuye ryo kugenzura inzira y'amakuru ya digitale (DSP) hamwe n'ikoranabuhanga ritandukanye rifite patenti, rifite ubushobozi bwo guhindura umutwaro wose kandi rikagira ubushobozi bwo gutwara umutwaro mu gihe gito.
4. HDI boards zifite ibisabwa byinshi cyane kugira ngo zikoreshwe mu gufunga ibyuma.
Byaba ari ingano y'ikibaho cyangwa imikorere y'amashanyarazi, HDI iruta PCB isanzwe. Buri giceri gifite impande ebyiri. Urundi ruhande rwa HDI ni uko kubera ko ikorwa nka PCB yo mu rwego rwo hejuru, ingano yayo mu gukora n'uburemere bwayo mu gutunganya ibintu biri hejuru cyane ugereranyije n'iya PCB zisanzwe. Hari kandi ibibazo byinshi bigomba kwitabwaho mu gihe cyo gukora - cyane cyane hifashishijwe icyuma gifunga.
Kuri ubu, ikibazo gikomeye mu gukora HDI n'ingorane bigiterwa no gucomeka. Iyo HDI idacometse neza, hazabaho ibibazo bikomeye by'ubuziranenge, harimo impande z'imbaho zitangana, ubugari bwa dielectric butangana, na pads zifite imyobo, nibindi.
Ubuso bw'ikibaho ntibungana kandi imirongo ntabwo igororotse, bigatera imiterere y'inkombe mu bihanamanga, bishobora gutera inenge nko gucika kw'imirongo no gucikamo ibice.
Impedance idasanzwe nayo izahinduka bitewe n'ubugari bwa dielectric budahuje, bigatera kudahuza kw'ibimenyetso.
Kuba igipfunyika gipfunyitse neza bizatuma habaho ubuziranenge bubi bw'ibipfunyika ndetse n'ibice byacyo bigatakaza agaciro.
Kubwibyo, si abakora PCB bose bafite ubushobozi n'imbaraga zo gukora akazi keza kuri HDI. Ifite uburambe bw'imyaka irenga 20 mu gukora PCB, RICHPCBA itanga ikoranabuhanga rigezweho ryo gukora circuit board zacapwe hamwe n'amahame meza yo mu rwego rwo hejuru ku nganda z'ikoranabuhanga. Ibicuruzwa birimo: PCB 1-68, HDI, PCB nyinshi, FPC, rigid pcb, flex pcb, rigid-flex pcb, ceramic pcb, high frequency pcb, nibindi. Hitamo RICHPCBA nk'uruganda rwawe rwizewe rwa PCB mu Bushinwa.
