Gadzirisa 8 Layer Pcb chiratidzo chekuvimbika uye matambudziko ekugovera wachi

Kana iwe uchibatanidzwa mune zvemagetsi uye akadhindwa edunhu mabhodhi (PCBs), iwe ungangodaro wakasangana nematambudziko akajairika nechiratidzo chekuvimbika uye kugovera wachi. Nyaya idzi dzinogona kunetsa kukunda, asi usatya!Mune ino blog positi, isu tichaongorora maitiro ekugadzirisa kutendeseka kwechiratidzo uye nyaya dzekugovera wachi pa8-layer PCBs. Kuti tikubatsire parwendo rwako, tinosuma Capel, kambani ine makore gumi nemashanu eruzivo mukugadzira PCB uye inopa kusimba kwehutongi hwemhando.

Kutendeseka kwechiratidzo chinhu chakakosha chePCB dhizaini sezvo ichivimbisa kuti masaini emagetsi anofambiswa mukati mePCB haana kuderedzwa kana kukanganiswa.Kana zviratidzo zvekuvimbika zvikaitika, huwori hwedata, kukanganisa kwenguva, uye kunyange kutadza kwehurongwa kunogona kuitika. Nokudaro, zvakakosha kugadzirisa matambudziko aya nemazvo.

Kugovera wachi, kune rumwe rutivi, kunoreva maitiro ekutumira masaini ewachi muPCB yese.Kugovera wachi kwakaringana kwakakosha kuwiriranisa uye nguva mukati memagetsi masisitimu. Kusafamba zvakanaka kwewachi kunogona kukonzera kuti zvinhu zvakasiyana siyana zvisashande, zvichikonzera kutadza kwehurongwa kana kutotadza zvachose.

Zvino, ngatinyure mune mamwe matekiniki uye gwara rekugadzirisa aya matambudziko:

1. Layer stacking dhizaini: Kunyatsorongwa kwakarongwa layer stacking ndiyo hwaro hwekuona kutendeseka kwechiratidzo uye kugovera wachi. 8-layer PCBs inopa kushanduka kukuru pakugadzira simba uye ndege dzepasi, zvichibatsira kuderedza ruzha uye kupa zviri nani chiratidzo chekuvimbika.Funga kushandisa simba rakaparadzana uye ndege dzepasi kune imwe neimwe chiratidzo chechiratidzo uye kushandisa ndege dzakavimbika dzekutarisa.

2. Impedance Control: Kuchengetedza kudzorwa kwekudzivirira mukati mePCB kunokosha kuratidza kuvimbika. Shandisa iyo impedance calculation tool kuona hupamhi hwekutsvaga uye nzvimbo inodiwa patambo yekutapurirana zvichienderana nePCB's zvinhu uye stackup.Nemakore gumi nemashanu ehunyanzvi hwekugadzira PCB, Capel inogona kupa hutungamiriri hwehunyanzvi uye ive nechokwadi chekutonga kwe impedance.

3. Tekinoroji yekufambisa: Tekinoroji yakakodzera yekufambisa inoita basa rakakosha mukugadzirisa kutendeseka kwechiratidzo uye nyaya dzekugovera wachi. Kushandisa mapfupi anoteedzera kunoderedza kunonoka kuparadzira chiratidzo uye kunoderedza kubatanidza ruzha.Shandisa masiginecha akasiyana kune masaini-kumhanya-mhanya kuti uwedzere kusadzivirirwa kweruzha. Pamusoro pezvo, hunyanzvi hwekufananidza hurefu hunoshandiswa kudzikisira nguva uye nyaya dzekubatanidza.

4. Decoupling capacitors: Kuisa decoupling capacitors pedyo neintegrated circuits (ICs) inobatsira kudzvinyirira ruzha uye kuvimbisa kugadzikana kwemagetsi panguva yekushanda kwepamusoro-frequency.Decoupling capacitors inopa yakaderera-impedance nzira yekuenda pasi, kuderedza kushanduka kwemagetsi uye kudzivirira kukanganiswa kwechiratidzo.

5. EMI kudzivirira: Electromagnetic interference (EMI) inogona kukanganisa zvakanyanya kutendeseka kwechiratidzo uye kugovera wachi.Kuita EMI ekudzivirira matekiniki, sekushandisa nhovo yakadzikwa inogona kana kuwedzera maitiro ekufambisa, inogona kuderedza EMI mhedzisiro uye kunatsiridza kuita kwese.

Zvino zvataongorora mhinduro dzinoshanda dzekusaina kuperera uye matambudziko ekugovera wachi, ngatiunze Capel - kambani ine ruzivo rwakakura uye yakanyatso kudzora mhando mukugadzira PCB.Nemakore gumi nemashanu ehunyanzvi hweindasitiri, Capel anonzwisisa kuomarara kwePCB dhizaini uye anogona kupa mhinduro dzakavimbika dzepurojekiti yako.

Capel yakazvipira kudzora hunhu hwakasimba kuti ive nechokwadi chekuti PCB yese yavanogadzira inosangana nepamusoro-soro.Kubva pachikamu chekutanga chekugadzira kusvika pakugadzirwa kwekupedzisira, Capel inoshandisa kuomarara kwekuyedza uye kuongorora maitiro kuti abvise chero chingave chiratidzo chekuvimbika kana nyaya dzekugovera wachi. Chikwata chavo chemainjiniya ane ruzivo chinogona kupa nzwisiso yakakosha uye nhungamiro yekuona kuti chirongwa chako chePCB chiri kubudirira.

Muchidimbu, kugadzirisa kusavimbika kwechiratidzo uye nyaya dzekugovera wachi ye8-layer PCB kunoda kunyatsoronga, hunyanzvi hwekugadzira, uye hunyanzvi hwakakodzera.Kuita maitiro akadai sekugadzirisa dhizaini, kuchengetedza inodzorwa impedance, kushandisa nzira dzakakodzera dzenzira, uye kubatanidza EMI kudzivirira maitiro kunogona kuvandudza zvakanyanya PCB kuita. Nemudiwa akavimbika seCapel, unogona kuzorora uine chokwadi chekuti PCB yako ichagadzirwa nemhando yepamusoro uye nemazvo. Saka, kumbundira mhinduro idzi uye ita yako inotevera PCB chirongwa chibudirire!
