Tora mutauri weBluetooth semuenzaniso wekubatanidza ruzivo rwekutanga rwe PCB dhizaini ive inoshanda kesi, uye tsanangura mashandiro uye chiitiko chinoshanda uye hunyanzvi hwePCB dhizaini software kuburikidza nekuita kwacho. Iyi kosi inodzidza iyo inoenderana ruzivo rwePCB wiring nekutsanangura muongororwo uye misimboti yeiyo wiring dhizaini.

Pfungwa dzakakosha dzeichi chidzidzo:

1. Wiring kuongorora uye nemisimboti

2.PCB wiring zvakakosha zvinodiwa

3. Impedance kudzora kwePCB wiring

Kudzidza matambudziko mune ino nguva:

1. Wiring kuongorora uye nemisimboti

2. Impedance kudzora kwePCB wiring

1. Wiring kuongorora uye nemisimboti

Mune echinyakare pcb dhizaini, iyo wiring pane iyo bhodhi inoshanda chete seye anotakura chiratidzo chekubatanidza, uye iyo pcb dhizainjiniya haidi kufunga nezvedanho rekuparadzira wiring.

Iine kukurumidza kuvandudzwa kweindasitiri yemagetsi, data riri kumedza kubva kumamigabyte mashoma panguva yeyuniti, makumi megabytes kusvika padanho re10Gbit / s yaunza kukurumidza kukurumidza kweiyi-yekumhanyisa dzidziso, pombi yePCB haichisiri nyore kubatanidza mutakuri. , asi kubva kuhutachiona hwetambo yekuongorora kukanganiswa kwenzvimbo dzakasiyana dzekuparadzira

Panguva imwecheteyo, kuomarara uye kuwanda kwePCB kuri kuwedzera panguva imwe chete, kubva kune yakajairika gomba dhizaini kuenda kune micro gomba dhizaini kune multistage bofu dhizaini dhizaini, kuchine kuvigwa kushorwa, kuvigwa mudziyo, dhizaini yeakakwira diki pcb wiring ku kuunza matambudziko akakura panguva imwe chete, zvakare inoda PCB dhizaini injinjini zvakanyanya-zvakadzama nzwisiso yeyakaitwa parameter eiyo PCB kugadzirwa uye kugadzirisa maitiro.

Nekuvandudzwa kwekumhanya kwakanyanya uye kwakanyanya density PCB, mainjiniya ekugadzira ePBB ari kuramba achiwedzera kukosha mukugadzirwa kwehardware, nepo iwo anoenderana pcb magadzirirwo ematambudziko ari kuramba achiwedzera, uye mainjiniya ekugadzira vanofanirwa kuziva mapoinzi eruzivo.

Mbiri, pcb wiring mhando

Iyo wiring mhando pane PCB pabhodhi inonyanya kusanganisira chiratidzo tambo, magetsi uye pasi tambo. Pakati pavo chiratidzo chetambo ndiyo yakajairika wiring, mhando yacho yakawanda. Ndichiri nemono mutsara maererano newiring fomu, musiyano mutsetse.

Zvinoenderana neyakaumbwa wiring, inogona zvakare kukamurwa kuita ribhoni mutsara uye microstrip mutsetse.

Iii. Ruzivo rwekutanga rwePCB wiring

General PCB wiring ine zvinotevera zvinodiwa:

(1) QFP, SOP uye mamwe mapakeji akaenzana emakadhi anofanirwa kutungamirwa kubva kuPIN nzvimbo (kazhinji achishandisa chimiro chepara).

(2) Mucheka (1) QFP, SOP uye mamwe mapakeji emapadhi akaenzana kunze kwetambo, kubva kuPIN nzvimbo (kazhinji achishandisa chimiro. Iyo nhanho kubva pamutsara kusvika kumucheto weplate haifanire kunge iri pasi pe20MIL.

Ongorora: mumufananidzo uri pamusoro, tsvuku ndiyo OUTLINE yefuremu rekunze rebhodhi, uye girini ndiyo routkeepin yenzvimbo yese yebhodhi wiring (iyo Routkeepin inodarika makumi maviri emamirioni yakamisikidzwa inoenderana neOUTLINE).

Ongorora: Iri bhodhi pamucheto rinosanganisirawo kuvhura kwewindo, milling groove, manera, yekugaya yakatetepa nharaunda nekugaya cutter kugadzirisa giraidhi kumucheto.

.

(4) Wiring haizove nezvikanganiso zveDRC, kusanganisira zita rimwe chete network network DRC zvikanganiso, kunze kwekugadzirwa kunoenderana, kunze kwekukanganisa kweDRC kunokonzerwa nekuzviputira pachayo.)

(5) Iko hakuna isina kubatika network mushure mePBB dhizaini, uye iyo pcb network inofanira kuenderana nedunhu dhayagiramu.

Haatenderwe kuenda kuDangline.

(7) Kana zviri pachena kuti mapads asingashande haadi kuchengetwa, anofanirwa kubviswa kubva kune yakajeka dhizaini faira.

(8) Inokurudzirwa kuti usatange hafu yedaro kubva kuhove huru 2MM

(9) Zvinokurudzirwa kushandisa wiring yemukati tambo dzemasaini

(10) Zvinokurudzirwa kuti inoenderana simba ndege kana yepasi ndege yenzvimbo yekumhanyisa chiratidzo chiratidzo kuti ichengetwe isina kukwana sezvazvinogona

(11) Zvinokurudzirwa kuti iyo wiring igovaniswe zvakaenzana. Mhangura inofanirwa kuiswa munzvimbo huru isina wiring, asi iyo impedance control haifanire kukanganiswa

(12) Zvinokurudzirwa kuti wiring yese inofanira kunge yakamomoterwa, uye iyo yekumusoro Angle iri 45 °

(13) Inokurudzirwa kudzivirira mitsara yemasaini kubva pakuumba yega-malops ane urefu hwemativi anopfuura 200ML mumativi ari pedyo

(14) Zvinokurudzirwa kuti iyo wiring kutungamira kwenzvimbo dzakatarisana kuve orthogonal mamiriro

Ongorora: Iyo wiring yezvikamu zviri padhuze inofanirwa kudzivirirwa munzira imwechete kudzikisira kutaura-pakati pezvikamu. Kana zvisingadzivisike, kunyanya kana chiyero chechiratidzo chakakwira, iyo pasi ndege inofanirwa kutariswa sekuparadzanisa yega yega wiring, uye iyo chiratidzo chevhu chinofanira kusiyanisa yega yega tambo yechiratidzo.

4. Impedance kudzora kwePCB wiring

Tsananguro: Hupamhi hwetambo muPCB yekugadzirisa yakakamurwa kuita zvikamu zviviri, hupamhi hwepamusoro nzvimbo uye upamhi hwepasi pevhu.
