HDI lub rooj tsavxwm , high density interconnect luam tawm Circuit Board
HDI boards yog ib qho ntawm cov thev naus laus zis loj tshaj plaws hauv PCBs thiab tam sim no muaj nyob hauv ABIS Circuits Ltd.
HDI boards muaj qhov muag tsis pom thiab / lossis faus vias, thiab feem ntau muaj microvias ntawm 0.006 lossis me dua.Lawv muaj qhov siab dua Circuit Court dua li cov laug cam kev sib tw.
Muaj 6 yam sib txawv ntawm HDI PCB pawg thawj coj saib , los ntawm qhov chaw mus rau qhov chaw los ntawm qhov, nrog rau faus qhov thiab los ntawm qhov, ob los yog ntau tshaj HDI khaubncaws sab nraud povtseg nrog los ntawm lub qhov, passive substrates tsis muaj hluav taws xob kev twb kev txuas, siv txheej khub Cov alternating qauv ntawm lub coreless qauv thiab cov coreless qauv siv txheej khub.
Printed Circuit Board nrog HDI technology Consumer Driven Technology Lub hauv ncoo ntawm cov txheej txheem txhawb nqa ntau cov thev naus laus zis ntawm cov txheej txheem tsawg dua, ua pov thawj tias qhov loj dua tsis yog ib txwm zoo dua.Txij li thaum xyoo 1980s lig, peb tau pom cov camcorders siv cov cartridges tshiab-loj, shrunk kom haum koj txhais tes.Kev suav xov tooj ntawm tes thiab ua haujlwm hauv tsev muaj kev siv thev naus laus zis ntxiv, ua rau cov khoos phis tawj nrawm dua thiab sib dua, tso cai rau cov neeg siv khoom ua haujlwm nyob deb ntawm txhua qhov chaw. HDI thev naus laus zis yog qhov laj thawj tseem ceeb rau cov kev hloov pauv no.Cov khoom muaj ntau lub zog, sib dua qhov hnyav thiab ntim me me.Cov cuab yeej tshwj xeeb, cov khoom siv micro thiab cov ntaub ntawv nyias nyias ua kom cov khoom siv hluav taws xob tuaj yeem ua rau me me thaum nthuav dav cov cuab yeej technology, zoo thiab ceev. Vias nyob rau hauv cov txheej txheem pad Kev tshoov siab los ntawm cov thev naus laus zis saum npoo av nyob rau xyoo 1980s tau thawb cov kev txwv ntawm BGA, COB, thiab CSP mus rau ib qho me me square inch.Lub hauv ncoo ntawm txheej txheem tso cai rau vias tso rau hauv qhov chaw ntawm lub tiaj tiaj.Cov los ntawm qhov yog plated thiab sau nrog conductive lossis non-conductive epoxy, ces npog thiab plated kom lawv yuav luag tsis pom. Nws suab yooj yim, tab sis nws yuav siv qhov nruab nrab ntawm yim kauj ruam ntxiv los ua kom tiav cov txheej txheem tshwj xeeb no.Cov cuab yeej tshaj lij thiab cov kws tshaj lij kev cob qhia zoo tau mloog zoo rau cov txheej txheem kom ua tiav qhov zoo meej zais hauv qhov. Los ntawm filling hom Muaj ntau yam sib txawv ntawm cov khoom siv los ntawm lub qhov: uas tsis yog-conductive epoxy, conductive epoxy, tooj liab-filled, silver-filled, thiab electrochemical plating.Cov no yuav ua rau lub qhov faus rau hauv av tiaj tus yuav tsum tau soldered tag nrho rau thaj av ib txwm muaj.Drilling, dig muag lossis faus vias, txhaws, plating thiab nkaum hauv qab SMT pads.Kev ua cov hom no los ntawm qhov yuav tsum tau siv cov cuab yeej tshwj xeeb thiab siv sijhawm ntev.Ntau lub sijhawm drilling thiab tswj qhov tob drilling nce lub sijhawm ua haujlwm. Nqi-zoo HDI Txawm hais tias qhov loj ntawm qee cov neeg siv khoom lag luam tau poob qis, qhov zoo tseem yog qhov tseem ceeb tshaj plaws ntawm cov neeg siv khoom tom qab tus nqi.Siv HDI thev naus laus zis hauv kev tsim, 8-txheej los ntawm-qhov PCB tuaj yeem raug txo mus rau 4-txheej HDI micro-qhov technology pob PCB.Lub peev xwm xaim ntawm HDI 4-txheej PCB tau tsim zoo tuaj yeem ua tiav tib yam lossis zoo dua ua haujlwm raws li tus qauv 8-txheej PCB. Txawm hais tias cov txheej txheem microvia nce tus nqi ntawm HDI PCB, tsim kom zoo thiab txo cov txheej txheem tuaj yeem txo tus nqi ntawm square inches ntawm cov khoom thiab cov txheej txheem ntau lawm. Tsim cov ntawv tsis sib xws HDI Kev ua tiav ntawm HDI PCB yuav tsum muaj cov cuab yeej tshwj xeeb thiab cov txheej txheem, xws li laser drilling, ntsaws, laser direct imaging, thiab nruam lamination mus.HDI board kab yog nyias, qhov sib nrug me dua, lub nplhaib yog nruj dua, thiab cov khoom siv tshwj xeeb thinner yog siv.Yuav kom ua tiav cov hom phiaj no, yuav tsum muaj sijhawm ntxiv thiab kev nqis peev loj hauv kev tsim khoom thiab cov khoom siv. Laser drilling tshuab Drilling qhov tsawg tshaj plaws micro-qhov tso cai rau ntau hom kev siv rau ntawm qhov chaw ntawm lub rooj tsavxwm.Siv lub nqaj nrog txoj kab uas hla ntawm 20 microns (1 mil), lub teeb pom kev zoo no tuaj yeem nkag mus rau cov hlau thiab iav los ua me me los ntawm qhov.Cov khoom tshiab tau tshwm sim, xws li cov laminates qis thiab cov khoom siv iav uas tsis tshua muaj dielectric.Cov ntaub ntawv no muaj kev kub siab dua rau kev sib dhos tsis muaj hlau lead thiab tso cai rau siv cov qhov me me. HDI board lamination thiab cov ntaub ntawv Advanced multilayer thev naus laus zis tso cai rau cov neeg tsim qauv ntxiv cov txheej txheem ntxiv rau hauv ib ntu los tsim cov txheej txheem PCB.Siv lub laser laum los tsim qhov hauv cov txheej sab hauv tso cai rau plating, duab, thiab etching ua ntej nias.Cov txheej txheem ntawm kev ntxiv no yog hu ua sequential build.SBU kev tsim khoom siv cov khoom ntim khoom ntim kom tso cai rau kev tswj xyuas thermal zoo dua
