Nekukurumidza kuchinja kwehupenyu hwemazuva ano hunoda mamwe maitiro ekuwedzera ayo anowedzera kushanda kwemabhodhi ako edunhu maererano nekushandiswa kwawo, kana kubatsira nematanho akawanda ekuunganidza maitiro ekuderedza kushanda uye kuvandudza kushanda zvakanaka, ANKE PCB iri kuzvipira. kusimudzira tekinoroji nyowani kuti isangane nezvinodiwa nemutengi.
Edge connector bevelling yechigunwe chegoridhe
Edge connector bevelling inowanzo shandiswa muzvigunwe zvegoridhe zvegoridhe rakapetwa mabhodhi kana ENIG mabhodhi, ndiko kucheka kana kuumbwa kwechibatanidza chemupendero pane imwe kona.Chero beveled connectors PCI kana imwe inoita kuti zvive nyore kuti bhodhi ipinde mukubatanidza.Edge Connector bevelling iri parameter mune yerodha ruzivo rwaunoda kusarudza uye tarisa iyi sarudzo kana ichidikanwa.
Carbon print
Carbon print inogadzirwa nekabhoni inki uye inogona kushandiswa kune kiibhodhi contacts, LCD contacts uye jumpers.Kudhinda kunoitwa ne conductive kabhoni inki.
Kabhoni zvinhu zvinofanirwa kuramba soldering kana HAL.
Insulation kana Carbon widths inogona kusadzikisira pasi pe75 % yehuwandu hwezita.
Dzimwe nguva chifukidzo chinoputika chinodiwa kudzivirira kubva kune akashandiswa fluxes.
Peelable soldermask
Peelable soldermask Iyo peelable resist layer inoshandiswa kuvhara nzvimbo dzisinga tengeswe panguva ye solder wave process.Iyi inochinjika layer inogona kuzozobviswa nyore nyore kusiya mapedhi, maburi uye nzvimbo dzinotengeswa mamiriro akakwana emagadzirirwo egungano rechipiri uye chikamu/chikonidzo chekuisa.
Bofu & vakavigwa vais
Chii chinonzi Bofu Via?
Mune bofu kuburikidza, iyo via inobatanidza iyo yekunze layer kune imwe kana anopfuura emukati machira ePCB uye ine basa rekubatana pakati peiyo yepamusoro layer uye yemukati.
Chii chinonzi Kuvigwa Via?
Mune yakavigwa kuburikidza, chete mukati mebhodhi zvidimbu zvakabatanidzwa ne via.Iyo "yakavigwa" mukati mebhodhi uye isingaoneki kubva kunze.
Mapofu uye akavigwa vias anonyanya kubatsira muHDI mabhodhi nekuti anokwenenzvera density yebhodhi pasina kuwedzera saizi yebhodhi kana huwandu hwemabhodhi anodiwa.
Maitiro ekugadzira mapofu & akavigwa vias
Kazhinji Isu hatishandise kudzika-inodzorwa laser drilling kugadzira mapofu uye kuvigwa vias.Chekutanga tinoboora cores imwe kana kupfuura uye ndiro nemakomba.Zvadaro tinovaka uye tinya stack.Iyi nzira inogona kudzokororwa kakawanda.
Izvi zvinoreva:
1. A Via nguva dzose inofanira kucheka nepakati nhamba yemhangura.
2. A Via haigoni kuguma kumusoro kudivi repakati
3. A Via haigoni kutanga pazasi divi musimboti
4. Bofu kana Kuvigwa Vias haigoni kutanga kana kupera mukati kana pakupera kwerimwe Bofu/Kuvigwa kuburikidza kunze kwekunge imwe yacho yakavharirwa zvachose mukati meimwe (izvi zvichawedzera mari yekuwedzera sekutenderera kwekuwedzera kunodiwa).
Impedance control
Impedans kudzora kwave kuri kumwe kwekunetseka kwakakosha uye matambudziko akakomba mukumhanyisa pcb dhizaini.
Mune yakakwirira-frequency application, inodzorwa impedance inotibatsira kuona kuti masiginecha haana kuderedzwa sezvaanofamba achitenderedza PCB.
Kupokana uye kuita kwedunhu remagetsi kune zvakakosha pakushanda, sezvo maitiro chaiwo anofanirwa kupedzwa pamberi pevamwe kuti ave nechokwadi chekushanda kwakakodzera.
Chaizvoizvo, inodzorwa impedance ndiko kuenzanirana kwe substrate zvinhu zvivakwa zvine tight dimensions uye nzvimbo kuti ive nechokwadi chekuti impedance yechiratidzo chetrace iri mukati meimwe muzana yehukoshi chaihwo.
