Raws li cov cuab yeej siv hluav taws xob ua rau me me thiab lawv cov qauv tsim ua ntau dua, xav tau me me PCB nrog qhov muab tso ua ke loj tshaj plaws yog nce. Qhov no yog tsav kev xav tau cov cuab yeej thiab thev naus laus zis uas tuaj yeem txhim kho qhov raug ntawm qhov me me, qhov nyuaj. Qhov no yog vim li cas kev sib txuas sib txuas siab (HDI) thev naus laus zis nthuav dav cov haujlwm ntawm ntu kev lag luam no. Cov thev naus laus zis tso cai rau kev tsim cov vaj huam sib luag tsis tshua muaj neeg nrog cov lej loj heev ntawm cov khoom ib square inch uas tuaj yeem txhim kho tau zoo. Kab lus no tshawb txog kev loj hlob thiab txiaj ntsig ntawm HDI PCB kev tsim khoom.

Qhov tseem ceeb ntawm kev siv HDI PCB kev tsim khoom

Feem ntau, PCBS muaj ib lossis ob txheej. Multilayer PCBS tuaj yeem muaj nyob txhua qhov ntawm 3 txog 20 txheej, nyob ntawm daim ntawv thov thiab nws qhov nyuaj. HDI PCBS tuaj yeem muaj 40 txheej thiab muaj cov khoom sib dhos tau zoo, cov kab nyias nyias thiab cov kab me me hauv qhov chaw me me. Koj tuaj yeem txheeb xyuas lawv los ntawm lawv cov kab nyias nyias. HDI PCB kev tsim khoom kuj tseem ua tiav hauv lwm qhov chaw. Ntawm no yog ib co ntawm lawv:

Nrog HDI, koj tuaj yeem muaj ntau yam kev tso cai thiab txheej ua ke. Txawm hais tias cov cores yog ib feem ntawm PCB txheej tsim, thiab lawv tau qhia hauv daim duab, HDI tuaj yeem ua tiav qhov tsim qauv dawb. Koj tuaj yeem muaj ob lossis ntau dua HDI los ntawm cov txheej txheej, nrog rau los ntawm qhov los ntawm qhov faus qhov, nrog ntau hom HDI cov laug cam. Ua raws txoj hauv kev hla qhov txheej txheem kom sib dhos ntau nrog tsawg kawg ntawm txheej. Yog tias koj piv qhov no rau cov txheej txheem ib txwm dhau los, koj tuaj yeem ncav cuag 8 txheej nrog kev pab ntawm 4 txheej ntawm HDI. Siv HDI, cov tsim qauv tuaj yeem yooj yim haum cov khoom me me nruj heev rau hauv qhov chaw me me. Ntxiv rau cov neeg siv khoom siv hluav taws xob thiab tsheb, HDI PCBS tshwj xeeb tshaj yog muaj txiaj ntsig hauv kev siv lub hom phiaj tseem ceeb, xws li kev tiv thaiv dav hlau thiab khoom siv kho mob.

Nov yog daim duab sawv cev ntawm HDI txheej ntawm yim txheej PCB: Cov txiaj ntsig ntawm HDI thev naus laus zis, HDI muab ntau yam txiaj ntsig rau PCB nrog rau cov khoom lag luam tag nrho. Nov yog qee qhov: Tsis muaj kev poob siab, HDI thev naus laus zis muab qhov raug siab tshaj plaws. HDI PCBS muaj lub teeb liab zoo dua qub thiab cov teeb liab poob qis piv rau cov thev naus laus zis yav dhau los. Nrog kev ua haujlwm siab, koj tuaj yeem laum qhov rau qhov me me, thaum nrog HDI, koj tuaj yeem tsim cov txheej sab hauv thiab sab hauv hauv qhov chaw compact PCB tshaj plaws. Nrog HDI, koj tuaj yeem muaj cov cores me me thiab ua haujlwm zoo heev. Koj tuaj yeem ua tiav qhov nruj nruj thiab tswj qhov tob drilling. Microbore tej zaum yuav me me, nrog qhov siab tshaj plaws ntawm 0.005. Nyob ntev, HDI PCB kev tsim khoom raug nqi vim nws txo cov txheej txheej. Zuag qhia tag nrho, nws txhim kho kev ua haujlwm hluav taws xob ntawm cov cuab yeej siv. Yog tias koj tab tom sib dhos HDI PCBS rau cov ntawv thov kev lag luam, nco ntsoov hu rau lub chaw tsim khoom PCB paub uas yuav nkag siab koj cov kev xav tau thiab kho lawv raws li qhov tsim nyog.
