Printed circuit boards ua tus nqi yeej ib txwm ua kom pom tseeb rau cov lag luam. Kev lees paub qhov tseem ceeb uas cuam tshuam rau pcb cov nqi ua haujlwm yog qhov tseem ceeb rau cov lag luam los tswj cov nqi thiab txhim kho kev ua haujlwm.
Khoom siv
Copper clad laminate khoom
Copper clad laminate, raws li cov khoom siv yooj yim ntawm pcb, muaj kev cuam tshuam loj rau tus nqi vim nws qhov zoo thiab hom. Cov khoom siv fr4 tooj liab- clad laminate nyob rau hauv kev ua lag luam yog dav siv hauv cov khoom siv hluav taws xob zoo tib yam vim nws cov nqi zoo- ua tau zoo, nrog tus nqi qis. Hauv cov chaw tshwj xeeb xws li siab - zaus thiab siab - circuits ceev, polytetrafluoroethylene substrates tau tshwm sim nrog lawv cov hluav taws xob zoo heev. Txawm li cas los xij, qhov kev ua tau zoo no los nrog tus nqi siab, uas yog siab dua li ntawm fr4 tooj liab zoo tib yam -clad laminates.
Copper foil parameters
Copper foil yog ib qho tseem ceeb ntawm pcb conductive circuits, thiab nws cov thickness, purity, thiab hom (dov tooj liab ntawv ci los yog electrolytic tooj liab ntawv ci) muaj qhov cuam tshuam loj rau tus nqi. Feem ntau, qhov tuab ntawm cov ntawv ci tooj liab, cov khoom siv raw yuav tsum muaj, thiab tus nqi nce ntxiv. Thaum tus nqi tooj liab nce, tus nqi ntawm cov ntawv ci tooj liab kuj nce ntxiv, uas ua rau cov nqi ua pcb nce. Tsis tas li ntawd, qee lub hom phiaj tshwj xeeb tooj liab foils, xws li qis profile tooj liab foils, yog kim dua li cov tooj liab zoo tib yam vim lawv txoj kev tsim khoom.
Lwm yam khoom siv
Ntxiv nrog rau tooj liab-clad laminates thiab tooj liab foils, lwm yam ntaub ntawv xws li solder mask number case thiab screen printing number case kuj tseem siv rau hauv kev ua pcb. Ntau hom thiab qhov zoo ntawm tus number case muaj tus nqi sib txawv. Piv txwv li, qee qhov kev ua tau zoo ntawm - solder mask inks muaj cov rwb thaiv tsev zoo dua thiab cov tshuaj tiv thaiv corrosion, thiab lawv cov nqi kuj siab. Txawm hais tias cov inks no suav nrog ib feem me me ntawm tag nrho cov khoom siv pcb tus nqi, lawv tuaj yeem sib sau thiab muaj qee yam cuam tshuam rau tus nqi pcb.
Manufacturing txheej txheem complexity
Txheej sib txawv
Tus naj npawb ntawm cov khaubncaws sab nraud povtseg hauv pcb yog ib qho tseem ceeb uas cuam tshuam rau tus nqi ua haujlwm. Kev tsim cov txheej txheem ntawm ib lub vaj huam sib luag thiab ob - sab vaj huam sib luag yog qhov yooj yim, yuav tsum muaj cov cuab yeej tsim khoom qis thiab cov kev xav tau, yog li tus nqi kuj pheej yig. Kev tsim khoom ntawm ntau- txheej boards (xws li 4, 6, thiab saum toj no) yog qhov nyuaj dua. Raws li tus naj npawb ntawm cov khaubncaws sab nraud povtseg nce, qhov nyuaj thiab precision yuav tsum tau rau zus tau tej cov txheej txheej circuits thiab lamination txheej txheem ho nce. Thaum ua ntau- txheej boards, yuav tsum muaj cov cuab yeej siv siab dua kom ntseeg tau tias kev sib raug zoo thiab kev sib raug zoo ntawm cov txheej txheem, thaum tseem xav tau kev ua haujlwm siab dua los ntawm cov kws tshaj lij. Rau txhua ob txheej ntxiv, tus nqi feem ntau nce.
txheej txheem tshwj xeeb
HDI dig muag faus board thev naus laus zis: Ntau theem HDI qhov muag tsis pom faus boards tuaj yeem ua tiav qhov kev teeb tsa zoo dua thiab kev sib koom ua ke ntau dua, thiab yog ib qho ntawm cov thev naus laus zis tseem ceeb rau kev ua haujlwm me me thiab kev ua haujlwm siab ntawm cov khoom siv hluav taws xob niaj hnub no. Txawm li cas los xij, nws cov txheej txheem tsim khoom suav nrog qib siab - cov txheej txheem kawg xws li laser drilling thiab nplua kab etching. Laser drilling yuav tsum tau cov cuab yeej laser meej thiab muaj cov kev xav tau siab heev rau qhov tseeb ntawm txoj haujlwm drilling, qhov tob, thiab qhov aperture. Ib qho kev sib txawv me ntsis tuaj yeem ua rau cov khoom seem. Fine circuit etching yuav tsum tau siv cov txheej txheem etching ntau dua thiab cov khoom siv los xyuas kom meej qhov tseeb thiab qhov zoo ntawm Circuit Court. Daim ntawv thov ntawm cov txheej txheem tshwj xeeb no ua rau cov nqi ntau lawm, ua rau tus nqi ntawm HDI dig muag faus boards ntau dua li cov pcbs zoo tib yam.
High zaus siab- nrawm board thev naus laus zis: Txhawm rau ua kom tau raws li qhov yuav tsum tau ua ntawm siab - zaus thiab siab-ceev teeb liab kis tau tus mob, hom pcb no muaj cov qauv nruj hauv kev xaiv pawg thawj coj saib xyuas, kev tswj hwm impedance, teeb tsa kev ncaj ncees tsim, thiab lwm yam. Hauv kev xaiv cov ntaub ntawv, siab - cov ntaub ntawv ua tau zoo xws li PTFE substrates tau hais ua ntej lawm feem ntau xav tau. Nyob rau hauv cov nqe lus ntawm impedance tswj, nws yog ib qhov tsim nyog los tswj cov impedance tus nqi ntawm lub Circuit Court, uas yuav tsum tau heev precision nyob rau hauv ntau lawm txheej txheem thiab cov khoom. Kev tsim teeb pom kev ncaj ncees yuav tsum tau ua tib zoo tsim hauv pcb layout, thaiv, thiab lwm yam kom txo tau cov teeb meem xws li teeb liab kev xav thiab crosstalk. Tag nrho cov txheej txheem tsim khoom yuav tsum muaj pab pawg kws tshaj lij thiab cov khoom siv ua haujlwm siab -precision production, uas ua rau muaj kev nce nqi ntawm kev ua haujlwm siab - zaus thiab siab - ceev boards.
machining raug
Qhov siab dua qhov yuav tsum tau ua rau kev ua pcb, tus nqi tsim khoom ntau dua. Kab dav / kab sib nrug yog ib qho tseem ceeb rau kev ntsuas pcb ua qhov raug. Cov kab dav dav / qhov sib txawv yuav nyob ib puag ncig 6mil. Yog hais tias cov khoom yuav tsum tau finer kab dav/spacing, xws li 3mil, siab precision exposure khoom, etching khoom, thiab nruj txheej txheem tswj yuav tsum tau thaum lub sij hawm ntau lawm txheej txheem. Raws li qhov siab - qhov yuav tsum tau muaj tseeb, tus nqi seem kuj tseem yuav nce ntxiv, ua rau muaj kev nce nqi. Ib yam li ntawd, nce qhov yuav tsum tau ua rau txoj kab uas hla qhov raug thiab qhov tseeb ntawm qhov chaw yuav ua rau kom qhov nyuaj thiab tus nqi ntawm kev ua haujlwm. Piv txwv li, drilling nrog me me apertures (xws li 0.2mm los yog tsawg dua) yuav tsum tau ntau tshaj drilling khoom thiab tshwj xeeb laum khoom, uas ho nce tus nqi ua.
Order kom muaj nuj nqis thiab lub sijhawm khoom xa tuaj

Qhov kev txiav txim kom muaj nuj nqis muaj feem cuam tshuam rau tus nqi pcb, feem ntau yog ua raws li txoj cai ntawm kev lag luam ntawm nplai. Thaum cov khoom ntim me me, xws li hauv cov qauv tsim cov theem, vim qhov xav tau tshwj xeeb kev debugging thiab kev npaj ua haujlwm, cov nqi ruaj khov (xws li cov khoom siv debugging, pwm cov nqi, thiab lwm yam) faib rau txhua pcb yog tus nqi siab, thiab chav tsev nqi kuj tseem siab. Raws li qhov ntau lawm, cov nqi ruaj khov tau faib rau ntau cov khoom, thiab cov nqi tsev yuav maj mam txo. Piv txwv li, ua tus qauv ntawm 10 pcbs yuav raug nqi 100 yuan ib thooj; Thaum qhov ntau lawm nce mus txog 1000 daim, tus nqi ib thooj yuav poob mus rau ib ncig ntawm 30 yuan. Rau qhov loj - kev txiav txim loj, cov tuam txhab lag luam kuj tseem tuaj yeem tau txais tus nqi zoo dua hauv kev yuav khoom raw, ntxiv txo cov nqi tsim khoom thiab muab cov neeg siv khoom ntau dua rau cov nqi txo nqi.
Lub sij hawm xa tuaj
Lub sij hawm xa tuaj kuj yog ib qho tseem ceeb cuam tshuam rau tus nqi ntawm kev ua pcb. Raws li lub sijhawm xa khoom tus qauv (xws li 5-7 hnub), txoj kev npaj tsim khoom tuaj yeem ua raws li ib txwm muaj, nrog kev faib cov peev txheej tsim nyog thiab tus nqi qis. Txawm li cas los xij, thaum cov neeg siv khoom muaj kev xav tau sai thiab thov kom nrawm nrawm (xws li 24-48 teev), cov tuam txhab yuav tsum tau kho lawv cov phiaj xwm tsim khoom sai sai thiab muab cov peev txheej tseem ceeb los ua cov ntawv xaj. Qhov no yuav txhais tau hais tias ua haujlwm dhau sijhawm rau cov neeg ua haujlwm, kev ua haujlwm ceev ntawm cov khoom siv, thiab txawm tias yuav tsum tau yuav cov khoom siv raw ntxiv kom tau raws li qhov xav tau sai. Txhawm rau ua kom tiav txoj haujlwm nyob rau lub sijhawm luv luv, cov tuam txhab tsim khoom yuav tsum them nyiaj ntxiv rau kev ua haujlwm, cov khoom siv, thiab cov nqi sijhawm, uas cuam tshuam rau tus nqi ntawm cov kev pabcuam nrawm. Feem ntau, expedited ntau lawm yuav tsum tau them cov nqi expedited.
