Nezve PCB Yedu Bhodhi Dhizaini

Kana isu tichigadzira bhodhi rePCB, isu tinewo seti yemitemo: kutanga, ronga nzvimbo huru yechikamu zvinoenderana nechiratidzo chechiratidzo, uye wozotevera "dunhu kutanga rakaoma uye zvakare nyore, chikamu vhoriyamu kubva kuhombe kusvika kudiki, chiratidzo chakasimba uye kuparadzaniswa kwechiratidzo chisina simba, chakakwirira uye chakaderera.Masiginecha akapatsanura, akasiyana analogi uye masaini edhijitari, edza kuita kuti wiring ive pfupi sezvinobvira, uye ita kuti marongerwo ave anonzwisisika sezvinobvira ”;kutarisisa kwakanyanya kunofanira kupihwa kuparadzanisa "signal ground" uye "simba pasi";izvi zvinonyanya kudzivirira pasi simba Mutsara dzimwe nguva une huru ikozvino inopfuura nayo.Kana iyi yazvino ikaunzwa muchiteshi chechiratidzo, inozoratidzwa kune inobuda terminal kuburikidza nechip, nekudaro ichikanganisa mashandiro emagetsi emagetsi ekuchinja.
Zvadaro, nzvimbo yegadziriro uye wiring kutungamira kwezvikamu zvinofanira kunge zvakaenderana sezvinobvira ne wiring yedhiyabhorosi yedunhu, iyo ichava yakanyanya nyore kune gare gare kugadzirisa uye kuongorora.
Waya yepasi inofanira kunge ipfupi uye yakafara sezvinobvira, uye waya yakadhindwa inopfuura nepainochinjisa ikozvino inofanirawo kuwedzerwa zvakanyanya sezvinobvira.Kazhinji, isu tine musimboti kana wiring, waya yepasi ndiyo yakakura, waya yemagetsi ndiyo yechipiri, uye waya yechiratidzo ndiyo yakamanikana.
Deresa iyo loop yemhinduro, yekupinda uye yekuburitsa rectification sefa loop nzvimbo zvakanyanya sezvinobvira, chinangwa ichi ndechekudzikisa kukanganiswa kweruzha rwekuchinja magetsi.

One-stop Solution

Inductive midziyo yakadai semathermistors inofanirwa kuchengetwa kure nekure sezvinobvira kubva kunzvimbo dzekupisa kana midziyo yedunhu inokonzera kukanganisa.
Chinhambwe chepakati pakati pemaviri-mu-mutsara machipisi chinofanira kunge chakakura kupfuura 2mm, uye chinhambwe chiri pakati pechip resistor uye chip capacitor chinofanira kunge chakakura kupfuura 0.7mm.
Iyo yekuisa sefa capacitor inofanirwa kuiswa padyo sezvinobvira kune mutsara unoda kusefa.
MuPCB board dhizaini, matambudziko akajairika ndeyekuchengetedza mitemo, EMC uye kupindira.Kuti tigadzirise matambudziko aya, isu tinofanirwa kutarisisa kune zvinhu zvitatu kana tichigadzira: nzvimbo kureba, creepage kureba uye insulation yekupinda chinhambwe.Impact.
Semuenzaniso: Creepage kureba: kana magetsi ekupinza ari 50V-250V, LN pamberi pefuse iri ≥2.5mm, apo magetsi ekupinza ari 250V-500V, LN iri pamberi pefuse ≥5.0mm;kubviswa kwemagetsi: apo magetsi ekupinza ari 50V-250V, L-N ≥ 1.7mm pamberi pe fuse, apo magetsi ekupinza ari 250V-500V, L-N ≥ 3.0mm pamberi pe fuse;hapana chinodiwa chinodikanwa mushure me fuse, asi edza kuchengeta imwe chinhambwe kuti udzivise kupfupika kwedunhu kukanganisa kune magetsi;chikamu chekutanga AC kusvika kuDC chikamu ≥ 2.0 mm;primary side DC ivhu kusvika pasi ≥4.0mm, senge primary side kusvika pasi;divi rekutanga kudivi rechipiri ≥6.4mm, senge optocoupler, Y capacitor uye zvimwe zvikamu zvechikamu, iyo pini spacing ishoma pane kana yakaenzana ne6.4mm kuti ipfurwe;transformer mbiri-nhanho ≥6.4mm kana kupfuura, ≥8mm yekusimbisa yakasimbiswa.

FAQ

Q1: unoita sei shuwa kunaka kwePCBs?
A1: MaPCB edu ese 100% bvunzo kusanganisira Flying Probe Test, E-test kana AOI.

Q2: Ndeipi nguva yekutungamira?
A2: Sample inoda 2-4 mazuva ekushanda, kugadzirwa kwemazhinji kunoda 7-10 mazuva ekushanda.Izvo zvinoenderana nemafaira uye huwandu.

Q3: Ndingawana mutengo wakanakisisa here?
A3: Hongu.Kubatsira vatengi kudzora mutengo ndizvo zvatiri kugara tichiedza kuita.Mainjiniya edu achapa yakanakisa dhizaini kuchengetedza PCB zvinhu.
