Cov nqi lag luam tawm hauv kev kho tshuab Cov Tshuab Hluav Taws Xob
Cov nqi tsim tawm rau PCBs ua qhov tseem ceeb nyob rau hauv nruab nrab mus rau siab ntim tsim lag luam. Qhov sib txawv ntawm ob peb pennies ib pawg tswj hwm yuav ntxiv ib qhov nyiaj ntau dhau sijhawm. Hauv kev txiav txim siab siv cov tshuab siv lossis laser drilling, tus nqi sib txawv thiab cov nqi sib txawv yuav tsum tau ua tib zoo ntsuas.
Yog tias koj tau xaiv los siv microvias hauv koj tus PCB, ib qho yuav tau xav txog yog tus nqi koom nrog kev siv laser drilling dhau kev siv tshuab. Lub tshuab txiav laser yog cov khoom siv kim, tab sis cov tshuab no muaj lub neej ntev. Kev xyaum tshuab yog pheej yig, tab sis lawv hnav tawm sai thiab xav tau hloov tshiab. Yog li thaum twg yuav tsum siv txhua txoj hauv kev no?
Cov txheej txheem uas tsim nyog rau tso vias hauv PCB feem ntau nyob ntawm qhov loj me thiab cov khoom siv hauv qab, tab sis kuj tseem muaj tus nqi lag luam tawm uas cuam tshuam rau lub qhov qhov. Txheem FR-4 nrog kwv yees li 0.1 hli sab nraud ntawm qhov yuav tuaj yeem sib tsoo nrog lub tshuab CNC. Laser drilling tseem tuaj yeem siv rau vias nrog lub taub loj dua. Txawm li cas los xij, muaj qhov nqi luam tawm uas tshwm sim thaum lub qhov nyiaj ntom ntom mus txog ib qib.
Thaum ib qho kuaj xyuas cov nqi ntau lawm cuam tshuam nrog kev siv tshuab kev sib piv piv rau laser drilling, ib qho pom tias cov nqi rau cov neeg kho tshuab drilling zoo li nthuav tawm laser drilling ib zaug lub qhov ntom ntuag nce dhau ib qib tseem ceeb. Cov nqi nce linearly nrog tus naj npawb ntawm vias uas yuav tsum tau tso rau ntawm board. Neeg kho tshuab drilling muaj cov nqi qis dua li laser drilling, thaum laser drilling muaj qis tus nqi sib txawv.
Qhov laj thawj tseem ceeb rau qhov nqi sib txawv yog cov cuab yeej tus nqi koom nrog kev siv tshuab. Tho cov khoom hnav tawm thiab thaum kawg yuav tsum tau hloov, thaum laser drilling tsis ua rau cov nqi sib txawv no. Ntawm qee qhov taw tes, muaj qhov tsis txaus ntawm lub qhov uas ob txoj kev tho yuav muaj tib tus nqi tag nrho. Rau 0.1 hli microvias, qhov ceev tseem ceeb yog txog 10 qhov ib square dm. Laser drilling yuav muaj qis dua tag nrho cov nqi ntawm qhov siab dua ntawm qhov ntom ntom.
Cov nqi saum toj saud kev lag luam tseem siv rau hauv-hauv-kab tsim. Thaum vias raug tso rau hauv cov ntaub qhwv ntawm PCB, lawv ib qho yuav tsum tau sau nrog kev coj ua thiab / lossis tsev ntaub nrog cov txheej txheem ntawm tus neeg xyuas kom tiv thaiv cam qhov sib tsoo los ntawm. Via-hauv ncoo plated dhau (VIPPO) qauv kuj tseem siv tau los tiv thaiv vuam cam.
Txawm hais tias koj npaj yuav los tsoo lub vias hauv koj lub PCB mechanically lossis siv laser drilling, koj xav tau PCB tsim software nrog ultra-raug CAD cov cuab yeej. HGTECH ua rau koj nkag mus rau qhov txheej txheem zoo tshaj plaws, kev sim, kev kuaj xyuas cov cai, thiab cov cuab yeej ua kom paub cov tiam. Tham nrog HGTECH tus kws tshaj lij hnub no yog tias koj xav paub ntau ntxiv txog yuav ua li cas tuaj yeem pab koj ua tiav koj cov hom phiaj tsim.
