Mukugadzirwa kwemaitiro e high-kumhanya PCB, wiring ndiyo hunyanzvi hwakanyanya uye hwakanyanya, mainjiniya anowanzo sangana nematambudziko akasiyana mukuita uku. Ichi chinyorwa chichatanga kuita sumo yekutanga kuPCB, uye panguva imwechete ita tsananguro yakapfava yemusimboti we wiring, pakupedzisira ichaunza inoshanda kwazvo ina PCB wiring hunyanzvi uye zvakakosha.

Heano mamwe matipi akanaka e wiring uye akakosha:

Chekutanga pane zvese, yekutanga sumo inoitwa. Kuwanda pcb akaturikidzana anogona kukamurwa chete rukoko, kaviri rukoko uye multi-rukoko. Single layer yakabviswa izvozvi. Double deck bhodhi iyo inonzwika system inoshandisa ikozvino yakawanda, ndeyekutarisa mhedzisiro seyakajairwa rough model board mwana, akawanda-layer board anonongedzera kusvika 4 kusvika pabhodhi re4 pamusoro zvinoti, kune density chinodiwa chechikamu chisina kureba. udza mana matete akakwana kazhinji. Kubva paAngle yekupfuura nepaburi inogona kukamurwa kuita kuburikidza gomba, bofu gomba, uye yakavigwa gomba. Gomba igomba rinobva kumusoro richienda pasi; Buri rakapofomara rakapfekwa kubva kumusoro kana rezasi gomba kusvika pakati nepakati, uyezve harirambe richipfekwa. Kubatsira uku ndekwekuti nzvimbo yegomba haina kuvharika kubva pakutanga kusvika kumagumo, uye mamwe matanda anogona kuramba achifamba pachinzvimbo chegomba. Gomba rakavigwa ndiro iri gomba rinopfuura nepakati pemesosphere kusvika ku mesosphere, rakavigwa, pamusoro pacho hachioneki zvachose. Mamiriro ezvinhu chaiwo anoratidzwa mumufananidzo uri pasi apa.

Pamberi pe otomatiki wiring, wiring ine yakakwirira zvinodiwa yeinopindirana mutsara pachine nguva, yekupinda uye inobuda parutivi mutsara haifanirwe kunge yakatarisana, kudzivirira kupindira kwekuratidzira. Kana zvichidikanwa, tambo dzepasi dzinogona kushandiswa kuzviparadzanisa, uye wiring yezvikamu zviviri zviri padhuze zvinofanirwa kunge zvakaringana kune mumwe nemumwe, nekuti matanda akafanana anowanzo kuburitsa kusangana kweparasiti. Mwero wekugovera weatomatiki wiring unoenderana nekurongeka kwakanaka, mitemo yewaya inogona kusetwa pachine nguva, senge nhamba yemitsara yekupeta, nhamba yekupfuura-maburi, nhamba yematanho, nezvimwe. Iko kuita yekuongorora mhando wiring kutanga kazhinji, kubatanidza mutsara mupfupi nekukurumidza, kupfuudza maze mhando wiring zvakare, chinongedzo chinoda jira chinotora nzira yepasirese wiring nzira, inogona kubvisa tambo yatove jira zvinoenderana nezvinodiwa uye edza kudzoreredza nzira zvakare. , kunatsiridza yakazara wiring maitiro nekudaro.

Zvekugadzwa, mutemo mumwe ndeyekuchengetedza dhijitari neanalogog seyakasiyana nepazvinogona, uye mutemo mumwe ndeyekuchengetedza yakaderera kumhanya kubva pakumhanya. Chinonyanya kukosha musimboti kupatsanura digitaalinen grounding uye analoginen grounding. Dhijitari yekumisikidza mudziyo wekuchinja, uye iyo yazvino yakakura kwazvo panguva yeswitch, uye diki kwazvo kana isingafambe. Naizvozvo, digital grounding haigone kusanganiswa neanalogog grounding. Rongedzo inokurudzirwa inogona kutaridzika seiri pazasi.

1. Kuchengetedza kwe wiring pakati pemagetsi uye pasi waya

(1) Kuwedzera decoupling capacitance pakati pemagetsi uye pasi waya. Iva nechokwadi chekubatanidza magetsi kune pini ye chip mushure me decoupling capacitor, nhamba inotevera inonyora nzira dzinoverengeka dzisina kururama dzekubatanidza uye nzira yakarurama yekubatanidza, isu tinotaura kune inotevera, pane kukanganisa kwakadaro here? Decoupling capacitor kazhinji ine mabasa maviri: imwe ndeyekupa iyo chip nekukurumidza hombe ikozvino, uye imwe ndeyekubvisa magetsi ekupa ruzha. Kune rumwe rutivi, ruzha rwemagetsi emagetsi runofanira kuderedzwa kuti ruchinje chip, uye kune rumwe rutivi, ruzha runogadzirwa ne chip harufanire kukanganisa magetsi.

(2) sezvinobvira kuwedzera simba uye tambo yepasi, iyo yakanakisa pasi waya yakafara kupfuura tambo yemagetsi, hukama hwayo ndehwe: pasi waya “simba mutsara” chiratidzo mutsara.

(3) Inogona kushandisa yakakura nzvimbo yemhangura yakatenderera sevhu, mubhodhi rakadhindwa harishandiswe munzvimbo iyi rakabatana nepasi, rekushandisa pasi, kana rakagadzirwa nemazhinji-masara, magetsi, pasi rimwe nerimwe rinotora dura.

2. Dhijitari redunhu uye analogineti redunhu kusanganisa kugadzirisa

Mazuva ano, maPCBS mazhinji haasisiri maseketi e-single-function, asi anoumbwa nemusanganiswa wedhijitari uye analogi masekete, saka kupindirana pakati pavo kunoda kutariswa kana uchifambisa, kunyanya kukanganiswa kweruzha pasi.

Nekuda kweiyo yakakwira frequency dhijitari maseketi, analog yedunhu senitivity yakasimba, kune mitsetse yechiratidzo, yakakwira frequency siginecha kusvika kure sezvinobvira kubva kune inonzwisa analog mudziyo, asi kune iyo PCB yese, PCB pasi waya kune ekunze nyika node inogona kuva neimwe chete. , saka inofanirwa kunge iri mukati mePCB yekugadzirisa, dhijitari wedunhu uye matambudziko eanalog wedunhu, uye mukati mebhodhi redunhu, Ivhu redunhu redhijitari uye ivhu redunhu reanalogi zvakanyatsopatsanurwa, chete pane interface (plug, nezvimwewo) uko iyo PCB yakabatana nenyika yekunze. Ivhu redhijitari redhijitari rakapfupika zvishoma pasi peiyo analog dunhu, ndapota cherechedza kuti pane imwe chete yekubatanidza poindi, kune zvakare isina kujairika pasi paPCB, izvi zvinoenderana nehurongwa hwekugadzira.

3. Kugadziriswa kwemakona emakona

Kazhinji pachava neshanduko yehukobvu pakona yemutsara, asi kana dhayamita yemutsara ichichinja, pachava nekuratidzira. Nezve kusiyana kwemakobvu emutsetse, angled chaiwo ndiwo akaipisisa, makumi mana nemashanu madhigirii ari nani, uye makona akapoteredzwa akanakisa. Nekudaro, makona akapoteredzwa anonetsa kuPCB dhizaini, saka inowanzo gadziriswa nekunzwa kwechiratidzo. Kazhinji, iyo 45 degree Angle inokwana chiratidzo, uye chete iyo mitsara yakaoma kwazvo inoda makona akapoteredzwa.

4. Tarisa mitemo yekugadzira mushure mekuisa mutsara

Pasinei nezvatinoita, tinofanira kuzviongorora kana tapedza, sezvatinofanira kutarisa mhinduro dzedu kana tasarirwa nenguva pabvunzo, inova nzira inokosha yokuti tiwane mamakisi epamusoro, uye zvakafanana kwatiri. kudhirowa PCB mapuranga. Nenzira iyi, tinogona kuva nechokwadi chekuti mabhodhi ematunhu atinodhirowa zvigadzirwa zvinogoneswa. Kuongorora kwedu kwakazara kune zvinotevera:

(1) ingave nhambwe iri pakati petambo nemutsetse, mutsetse uye chinhu chepadhi, tambo uye nepakati-gomba, chinhu chepadhi uye nepakati-gomba, kuburikidza-gomba uye nepakati-gomba zvine musoro, kunyangwe kusangana nezvinodiwa mukugadzira.

(2) Kunyangwe hupamhi hwetambo yemagetsi uye tambo yepasi yakakodzera, ingave magetsi uye tambo yepasi zvakabatanidzwa zvakanyanya (yakaderera wave impedance), uye kana paine nzvimbo muPCB yekuti tambo yepasi iwedzerwe.

(3) Kunyangwe matanho akakwenenzverwa akatorwa kumatambo ekiyi echiratidzo, sehurefu hupfupi, mitsara yekudzivirira, mitsara yekuisa uye mitsara yekubuditsa zvakaparadzaniswa zvakajeka.

(4) Analogi wedunhu uye dijitari redunhu chikamu, kana paine yakazvimirira pasi waya.

(5) Kunyangwe iwo magiraidhi (senge ICONS uye notations) akawedzerwa kuPCB anokonzera chiratidzo pfupi wedunhu.

(6) Shandura mimwe mitsetse isingafadzi.

(7) Kunyangwe mutsara wekuita wakawedzerwa paPCB, ingave iyo yekupokana welding inosangana nezvinodiwa zvekugadzirwa kwemaitiro, kana saizi yekushivirira yakakodzera, uye kana chiratidzo chechimiro chakatsikirirwa pane welding padhi yechigadzirwa, kwete kukanganisa mhando yemidziyo yemagetsi.

(8) Kunyangwe iyo yekunze furemu mupendero wesimba rekupa magetsi muyakawanda-layer board yakaderedzwa, senge foil yemhangura yakafumurwa kunze kwebhodhi remagetsi emagetsi zviri nyore kukonzera pfupi pfupi.

Zvese mune zvese, hunyanzvi hwepamusoro uye nzira zviitiko, izvo zvakakodzera kudzidza kana isu tichidhirowa PCB board. Mukuita kwekudhira pcb, pamusoro pekushandisa zvine hunyanzvi zvekushandisa zvekudhirowa, isu tinofanirwa zvakare kuve neruzivo rwakasimba rwezvinyorwa uye neruzivo rwekuita, izvo zvinogona kukubatsira kupedzisa mepu yako yePBB nekukurumidza uye zvine mutsindo. Asi pane zvakare yakakosha poindi, ndiko kuti, isu tinofanirwa kungwarira, zvisinei kuita wiring kana kwakazara dhizaini nhanho dzese dzinofanirwa kuve dzakangwarira uye dzakakomba, nekuti chako chikanganiso chidiki chinogona kutungamira kune chako chekupedzisira chigadzirwa chichava dongo, uyezve haugone kuwana zvakaipa, Saka isu toda kupedza nguva yakawanda pakuita kudhirowa kuti tinyatso tarisisa zvese pane kudzokera kunoona kana chimwe chinhu chisina kumira zvakanaka, izvo zvinogona kutora nguva yakawanda. Muchidimbu, maitiro ePBB anoteerera kune izvozvi.
