Mazano ekugadzirisa
MuPCB marongerwo maitiro, yekutanga kutarisisa saizi yePCB.Tevere, isu tinofanirwa kufunga nezvezvishandiso nenzvimbo dzine zvimiro zvekumisikidza zvinodiwa, senge paine muganho wehurefu, muganho wehupamhi uye punching, nzvimbo dzakatsvetwa.Zvadaro maererano nechiratidzo chedunhu uye simba rekuyerera, pre-layout yega yega yedunhu module, uye pakupedzisira maererano nemaitiro ekugadzirisa ega ega module module kuita marongerwo ezvese zvikamu zvinoshanda.
Nheyo dzekutanga dzemarongerwo
1. Kurukura nevashandi vakakodzera kuti vasangane nezvinodiwa zvakakosha muchimiro, SI, DFM, DFT, EMC.
2. Maererano nechimiro chechimiro chedhiyagiramu, nzvimbo yekubatanidza, maburi ekukwira, zviratidzo uye zvimwe zvigadziri zvinoda kuiswa, uye kupa midziyo iyi isingazungunuke hunhu uye dimensioning.
3. Zvinoenderana nechimiro chechimiro dhayagiramu uye zvakakosha zvinodiwa zveimwe michina, isa inorambidzwa wiring nzvimbo uye inorambidzwa dhizaini nzvimbo.
4. Kunyatsofungisisa kwePCB kushanda uye kubudirira kwekugadzirisa kusarudza nzira yekugadzirisa kuyerera (inonyanya kukosha kune imwe-sided SMT; single-sided SMT + plug-in.
Kaviri-sided SMT;kaviri-sided SMT + plug-in), uye zvinoenderana nemagadzirirwo eakasiyana maitiro ekugadzirisa maitiro.
5. marongerwo maererano nemigumisiro ye-pre-layout, maererano ne "yekutanga yakakura, iyo idiki, yekutanga yakaoma, uye iri nyore" hurongwa hwekugadzirisa.
6. marongerwo anofanirwa kuedza kuzadzisa zvinotevera zvinodiwa: mutsara wose wakapfupika sezvinobvira, mitsetse yakapfupika yechiratidzo;high voltage, high current signals uye low voltage, diki yazvino chiratidzo chisina simba chiratidzo chakaparadzana zvachose;analog chiratidzo uye chiratidzo chedhijitari chakaparadzana;high frequency signal uye low frequency signal inoparadzaniswa;high frequency components of the spacing kuti ive yakakwana.Muchiitiko chekusangana nezvinodiwa zvekufananidza uye kuongorora nguva, kugadziriswa kwenzvimbo.
7. The zvakafanana redunhu zvikamu kure sezvinobvira kushandisa symmetrical modular marongerwo.
8. marongero emagadzirirwo anokurudzirwa gidhi ye50 mil, IC mudziyo dhizaini, grid inokurudzirwa 25 25 25 25 25 mil.dhizaini density yakakwira, zvidiki zvidiki zvekumisikidza, zvigadziriso zvegidhi zvinokurudzirwa zvisingasviki 5 mil.
Nheyo yegadziriro yezvikamu zvakakosha
1. nepazvinobvira kupfupisa kureba kwekubatana pakati pezvikamu zveFM.Inotarirwa kune zvinokanganisa zvikamu hazvigone kuve padhuze kune mumwe nemumwe, edza kudzikisa yavo yekugovera paramita uye mutual electromagnetic kupindira.
2. nokuti zvinobvira kuvapo yepamusoro zvinogona musiyano pakati mudziyo uye waya, anofanira kuwedzera chinhambwe pakati pavo kudzivirira netsaona pfupi redunhu.Midziyo ine magetsi akasimba, edza kuronga munzvimbo dzisingasviki nyore kuvanhu.
3. Huremu hunopfuura 15g components, inofanira kuwedzerwa bracket yakatarwa, uye ipapo welding.Kune makuru uye anorema, anopisa-anogadzira zvikamu hazvifanirwe kuiswa paPCB, akaiswa mudzimba dzese anofanirwa kufunga nezve nyaya yekupisa kupisa, kupisa-sensitive zvishandiso zvinofanirwa kunge zviri kure nemagetsi ekugadzira kupisa.
4. ye potentiometers, inogadziriswa inductor coils, variable capacitors, micro switches uye zvimwe zvinogadziriswa zvikamu marongerwo anofanirwa kufunga nezvezvimiro zvinodiwa zvemuchina, senge kureba, kukura kwegomba, pakati coordinates, nezvimwe.
5. Pre-position the PCB positioning maburi uye fixed bracket inogarwa nechinzvimbo.
Post-layout cheki
MuPCB dhizaini, dhizaini inonzwisisika ndiyo nhanho yekutanga mukubudirira kwePCB dhizaini, mainjiniya anofanirwa kunyatso tarisa zvinotevera mushure mekugadzirisa kwapera.
1. PCB saizi mamaki, dhizaini dhizaini inopindirana nemadhirowa echimiro, ingave inosangana nePCB yekugadzira maitirwo ezvinodiwa, senge dhayamita yegomba, upamhi hwemutsara hudiki.
2. kana zvikamu zvinopindirana mune maviri-dimensional uye matatu-dimensional nzvimbo, uye kana ivo vachizopindirana pamwe chete nekugadzirisa imba.
3. kana zvikamu zvose zvakaiswa.
4. kudiwa kwekugara uchivhara kana kuchinjwa kwezvikamu zviri nyore kuvhara uye kutsiva.
5. Pane chinhambwe chakakodzera here pakati pemudziyo wekupisa uye zvinhu zvinogadzira kupisa.
6. Zviri nyore here kugadzirisa iyo inogadziriswa mudziyo uye tinya bhatani.
7. Ingave nzvimbo yekuiswa kwekupisa kupisa imhepo yakatsetseka.
8. Kunyangwe kuyerera kwechiratidzo kuri nyore uye kupfupika kwekubatanidza.
9. Kana dambudziko rekupindira kwemutsara rakatariswa.
10. Ko ipulagi, socket inopesana nekugadzirwa kwemichina.
