Single Layer PCB Vs Multi Layer PCB - Zvakanakira, Zvakaipa, Dhizaini uye Kugadzira Maitiro.
Pamberikugadzira bhodhi redunhu rakadhindwa, unofanira kusarudza kushandisa single-layer kana multi-layer PCB.Mhando mbiri dzekugadzira dzinoshandiswa mumidziyo yakawanda yemazuva ese.Rudzi rwepurojekiti yauri kushandisa bhodhi ichasarudza kuti ndeipi yakakunakira iwe.Multi-layer boards anonyanya kuwanda kune yakaoma michina, nepo single-layer board inogona kushandiswa kune zviri nyore zvishandiso.Ichi chinyorwa chichakubatsira iwe kunzwisisa mutsauko uye sarudza mhando yakakodzera yeprojekti yako.
Zvichienderana nemazita ePCBs aya, unogona kufungidzira kuti musiyano chii.Rimwe-layer board rine imwe layer ye base material (inozivikanwawo se substrate), nepo mabhodhi e-multi-layer ane zvidimbu zvakawanda.Paunenge uchiaongorora zvakanyanya, uchaona misiyano yakawanda mumagadzirirwo uye kushanda kwemapuranga aya.
Kana iwe uchida kuverenga zvakawanda pamusoro pemhando mbiri idzi dzePCB, ramba uchiverenga!
Chii chinonzi Single Layer PCB?
Single-sided boards inonziwo single-sided boards.Vane zvikamu kune rumwe rutivi uye conductor pateni kune rumwe.Aya mapuranga ane imwe layer ye conductive material (kazhinji mhangura).Rimwe-layer board rine substrate, conductive metal layers, inodzivirira solder layer, uye sirika sikirini.Mabhodhi e-single-layer anowanikwa mune zvakawanda zvemagetsi zviri nyore.
Zvakanakira Single Layer PCB
1. Zvisingadhuri
Pakazere, imwe-layer PCB haina kudhura nekuda kwekureruka kwayo dhizaini.Imhaka yekuti inogona kuvandudzwa nenzira-inoshanda pasina kuvimba nehuwandu hwehuwanduPCB zvinhu.Uyezve, hazvidi ruzivo rwakawanda.
2. Kukurumidza Kugadzirwa
Iine dhizaini yakapfava uye yakaderera-zvishandiso kuvimba, single-layered PCBs inogona kugadzirwa pasina nguva!Ehe, iyo mukana wakakura, kunyanya kana iwe uchida PCB nekukurumidza sezvinobvira.
3. Nyore Kugadzira
Iyo yakakurumbira single-layer PCB inogona kugadzirwa pasina matambudziko ehunyanzvi.Imhaka yekuti inopa yakapusa dhizaini maitiro kuitira kuti vagadziri uye nyanzvi vagone kuvagadzira pasina matambudziko.
4. Unogona kuhodha muBulk
Nekuda kwemaitiro avo ari nyore ekuvandudza, unogona kuraira akawanda emhando idzi dzePCB panguva imwe chete.Iwe unogona kutotarisira kuona kudonha kwemitengo pabhodhi kana iwe ukaodha muhuwandu.
Zvakashata zveSingle Layer PCB
1. Kumhanya kwakaganhurirwa uye Kugona
Aya mabhodhi edunhu anopa mashoma sarudzo dzekubatanidza.Izvi zvinoreva kuti simba rose nekumhanya zvichadzikira.Uyezve, simba rekushanda rinodzikira nekuda kwekugadzirwa kwayo.Dunhu rinogona kusashanda kune-high-power application.
2. Haisi kupa Space yakawanda
Complex zvishandiso hazvizobatsiri kubva kune imwechete-layer redunhu bhodhi.Imhaka yekuti inopa nzvimbo shoma shoma yekuwedzeraZvikamu zveSMDuye zvisungo.Waya dzinosangana dzinoita kuti bhodhi rishande zvisina kunaka.Nzira yakanakisisa inosanganisira kuvimbisa kuti bhodhi redunhu rinopa nzvimbo yakakwana yezvose.
3. Yakakura uye Inorema
Iwe unozofanirwa kuita kuti bhodhi ive yakakura kuti upe humwe humwe hunyanzvi hwezvinangwa zvakasiyana-siyana zvekushanda.Nekudaro, kuita izvi kuchawedzerawo huremu hwechigadzirwa.
Kushandiswa kweSingle Layer PCB
Nekuda kwemutengo wavo wakaderera wekugadzira, mabhodhi ane divi rimwe chete anozivikanwa mumidziyo yakawanda yemumba uyezvemagetsi zvevatengi.Izvi zvakakurumbira kune zvishandiso zvinogona kuchengeta data shoma.Mimwe mienzaniso inosanganisira:
● Vagadziri vekofi
● Mwenje ye LED
● Makarukureta
● Redhiyo
● Zvigadzirwa zveMagetsi
● Mhando dzeSensor dzakasiyana
● Solid State Drives (SSD)
Chii chinonzi Multilayer Layer PCB?
Multi-layer PCBs ine akawanda maviri-mativi mabhodhi akaturikidzana pamusoro peimwe.Vanogona kuva nemapuranga akawanda sezvinodiwa, asi rakareba rakagadzirwa raiva 129-layer gobvu.Vanowanzova pakati pe4 ne12 layers.Nekudaro, huwandu husina kujairika hunogona kutungamira kumatambudziko senge warping kana kumonyoroka mushure mekutengesa.
A-multi-layer board's substrate layers ane conductive simbi padivi rega rega.Bhodhi rega rega rinobatanidzwa uchishandisa adhesive yakasarudzika uye insulating material.Iwo ma-multi-layer board ane solder masks kumucheto.
Zvakanakira zveMultilayer Layer PCB
1. Complex Projects
Midziyo yakaoma inotsamira pane zvimwe zvikamu uye maseketi kazhinji inoda akawanda-layer PCB.Iwe unogona kuwedzera bhodhi kuburikidza nekuwedzera layer yekubatanidza.Izvi zvinoita kuti ive yakakodzera kune mamwe maseketi ane mamwe maratidziro, ayo neimwe nzira asingakwane pane yakajairwa bhodhi.
2. More Durable
Mamwe machira anowedzera ukobvu hwebhodhi, zvichiita kuti igare yakasimba.Izvi zvinozoita kuti hupenyu hurefu uye huchibvumira kurarama zviitiko zvisingatarisirwi, kusanganisira madonhwe.
3. Kubatana
Zvikamu zvinoverengeka zvinowanzoda zvinopfuura imwe nzvimbo yekubatanidza.Muchiitiko ichi, PCB yakawanda-layer inongoda imwe nzvimbo yekubatanidza.Pakazara, mukana uyu unobatsira kune dhizaini iri nyore uye huremu maficha.
4. Rakawanda Simba
Kuwedzera kuwanda kune akawanda-akaturikidzana PCB inoita kuti ive inoshanda kune-simba-ane simba zvishandiso.Kazhinji, izvi zvinoreva kuti inogona kushanda nekukurumidza uye nemazvo.Iyo yakawedzera huwandu inoita kuti ive yakakodzera kune zvine simba zvishandiso.
Zvakaipa zveMultilayer Layer PCB
1. Zvakawanda Zvinodhura
Iwe unogona kutarisira kubhadhara yakawanda neakawanda-layered redunhu bhodhi sezvo inoda zvimwe zvekushandisa, hunyanzvi, uye nguva yekuvandudza.Nechikonzero ichi, iwe unofanirwa kuve nechokwadi kuti kushandisa yakawanda-layer chikamu kune zvakanakira kupfuura mutengo.
2. Yakareba Nguva Yekutungamira
Multi-layer boards inotora nguva yakareba kuti ivandudzwe.Izvi zvinokonzerwa nezvikamu zvakakosha zvinoda kukiyiwa kuitira kuti imwe neimwe layer iite bhodhi rega.Imwe neimwe yeaya maitiro anobatsira kune yakazara kupedzisa nguva.
3. Kugadzirisa kunogona kuva Complex
Kana PCB ine multi-layered ikasangana nematambudziko, zvino zvinogona kunetsa kugadzirisa.Mamwe matinji emukati anogona kusatariswa kubva kunze, zvichiita kuti zvinyanye kuonesa chiri kukonzera kukuvara kwechikamu kana chemuviri bhodhi.Uyezve, iwe uchafanirwa kufunga nezvehuwandu hwezvinhu zvakabatanidzwa pabhodhi nekuti zvinoita kuti kugadzirisa kuome kupedzisa.
Musiyano: Single Layer PCB Vs Multi Layer PCB
1. Manufacturing Process
A single layer PCB inopinda maitiro akareba ekugadzira.Kazhinji, zvinosanganisira kushandisa akawandaCNC machiningmaitiro ekugadzira bhodhi.Iyo yese maitiro inosanganisira kucheka-kuchera-graphics kuiswa-etching-solder mask uye kudhinda.
Mushure mezvo, inoenda kuburikidza nekurapwa kwepamusoro isati yaedzwa, kuongororwa, uye kurongedzerwa kutakurwa.
Zvichakadaro, maPCB akawanda anogadzirwa kuburikidza nemaitiro akakosha.Zvinosanganisira kufukidza prepreg uye nheyo dzezvinhu zvikamu pamwe chete kuburikidza nekumanikidza kwakanyanya uye tembiricha.Izvi zvinoita kuti mweya usapindire pakati pechikamu chimwe nechimwe.Zvakare, zvinoreva kuti resin inovhara maconductor uye inonamira kuchengetedza imwe neimwe layer inonyungudika uye inorapa nemazvo.
2. Zvinhu
Single-layer uye akawanda-layer PCB anogadzirwa achishandisa simbi, FR-4, CEM, Teflon, uye polyimide zvinhu.Kunyange zvakadaro, mhangura ndiyo inonyanya kusarudzwa.
3. Mutengo
Pakazere, iyo single-layer PCB haina kudhura pane yakawanda-layer PCB.Izvi zvinonyanya kukonzerwa nezvinhu zvinoshandiswa, nguva yekugadzira, uye hunyanzvi.Zvimwe zvinhu zvinogona kukanganisa mutengo, kusanganisira saizi, lamination, nguva yekutungamira, nezvimwe.
4. Kushandisa
Kazhinji, ma-PCB e-single-layer anoshandiswa kune zvishandiso zviri nyore, nepo akawanda-layer PCBs ari kunyanya kushanda kune tekinoroji yepamusoro, senge mafoni.
Kufunga kana iwe uchida single-layer kana akawanda-layer PCBs
Zvaizobatsira kana iwe ukaziva kuti akawanda-layer kana single-layer akadhindwa edunhu mabhodhi anodiwa kuprojekiti yako.Zvadaro, funga kuti ndeupi rudzi rwepurojekiti yaunayo uye kuti yakanyatsokodzera chii.Iyi ndiyo mibvunzo mishanu yaunofanira kuzvibvunza:
1. Ndeipi nhanho yekushanda yandichada?Iwe unogona kuda mamwe ma layer kana zvakanyanya kuoma.
2. Ndeipi yakakura yebhodhi saizi?Multi-layer boards inobvumira kushanda kwakawanda munzvimbo diki.
3. Unokoshesa kusimba here?Multi-layer ndiyo yakanakisa sarudzo kana kusimba kuri pamberi.
4. Ndinofanira kushandisa marii?Single-layer boards ndiyo yakanakira mabhajeti ari pasi pe $500.
5. Ndeipi nguva yekutungamira yePCBs?Nguva yekutungamira ye-single-layer yakadhindwa redunhu bhodhi ipfupi pane yeakawanda-layer board.
Mimwe mibvunzo yehunyanzvi, senge frequency yekushanda, density, uye masignal layer, inozoda kugadziriswa.Iyi mibvunzo ichaona kana iwe uchida bhodhi rine imwe, mitatu, ina, kana kupfuura.
