Mabasa ega rega rega muBare PCB board

Vazhinjiisina PCB boarddhizaini vanofarira, kunyanya manovices, havana nzwisiso yakakwana yeakasiyana akaturikidzana mukatibarePCB bhodhi dhizaini, uye havazive mabasa avo uye kushandiswa.Heino tsananguro yakarongeka kwauri:

1. Mechanical layer ndiyo kutaridzika kweiyo yese isina chinhu PCB board yekupedzisa mekinika.Muchokwadi, kana tichitaura nezve mechanical layer, tinoreva chimiro uye chimiro cheyose isina chinhu PCB board.Inogona zvakare kushandiswa kuseta hukuru hwebhodhi, data mamaki, kurongeka mamaki, mirairo yegungano uye rumwe ruzivo rwemuchina.Iyi ruzivo inosiyana zvichienderana nezvinodiwa nekambani yekugadzira kanaPCB mugadziri.Mukuwedzera, mechanical layers inogona kusungirirwa kune mamwe ma layer kuti ibudise kuratidza pamwe chete.

2. Chengetedza kunze layer (yakarambidzwa wiring layer), inoshandiswa kutsanangura nzvimbo iyo zvikamu uye wiring zvinogona kuiswa zvinobudirira pabhodhi rePCB risina chinhu.Nzvimbo yakavharwa inodhirowewa pane iyi dhizaini senzvimbo inoshanda yekufambisa, uye otomatiki yekuisa uye nzira haigone kuitwa kunze kwenzvimbo iyi.Iyo yakarambidzwa wiring layer ndiyo muganhu patinotsanangura mhangura yemaitiro emagetsi, ndiko kuti, mushure mekunge tatsanangura iyo yakarambidzwa wiring layer yekutanga, mune inotevera wiring process, hazvigoneke kuti waya dzine hunhu hwemagetsi dzipfuure zvakarambidzwa. wiring.Muganhu weiyo layer unowanzoshandiswa kushandisa Chengeta kunze layer se mechanical layer.Iyi nzira haina kunaka, saka zvinokurudzirwa kuti iwe usiyanise, zvikasadaro fekitori yebhodhi ichakupa hunhu shanduko nguva dzese dzaunoburitsa.

3. Chiratidzo chechiratidzo: Chiratidzo chechiratidzo chinonyanya kushandiswa kuronga mawaya paPCB board isina chinhu.Kusanganisira top layer (yepamusoro layer), yezasi layer (yezasi layer) uye 30 MidLayer (yepakati layer).Zvishandiso zvinoiswa paPamusoro nepamusoro pezvikamu, uye zvidimbu zvemukati zvinofambiswa.

4. Paste yepamusoro uye pasi pasi ndiyo yepamusoro uye pasi pedhi stencil layers, iyo yakaenzana nehukuru hwepadhi.Izvi zvinonyanya nekuti isu tinogona kushandisa aya maviri akaturikidzana kugadzira stencils patinoita SMT.Isu takangochera gomba saizi yepedhi pamambure, tobva taisa simbi mesh chivharo paPCB board isina chinhu, ndokukwesha solder paste zvakaenzana nebhurasho rine solder paste.

5. Pamusoro Solder uye Pazasi Solder Iyi ndiyo solder mask kudzivirira kuvharwa kwemafuta egirini.Tinowanzoti "kuvhura hwindo".Yakajairika mhangura kana zviteshi zvakafukidzwa nemafuta egirinhi nekukasira.Kana isu tikanyatsovhara solder mask layer Kana ikabatwa, inodzivirira mafuta egirinhi kubva pakuifukidza uye kuburitsa mhangura.

6. Internal plane layer (simba remukati / pasi pasi): Rudzi urwu rwechifukidzo runoshandiswa chete kune mapuranga akawanda, kunyanya kuronga mitsara yemagetsi uye mitsara yepasi.Isu tinovadaidza kuti mapuranga maviri-layer board, mana-layer board, uye matanhatu-layer mabhodhi, ayo anowanzo reva nhamba yezviratidzo zvechiratidzo uye mukati simba / pasi ndege.

7. Silkscreen layer: Silkscreen layer inonyanya kushandiswa kuisa ruzivo rwekudhinda, senge ratidziro uye mabhii ezvikamu, mavara akasiyana-siyana ezvinyorwa, nezvimwewo. Altium inopa Kufukidzira Kwepamusoro uye Pazasi Kufukidzira zvidimbu zviviri zvesirikirini, zvichiteerana, kuisa faira repamusoro resirikirini. uye pasi silk screen faira.

8. Multi layer: Mapedhi uye inopinda vias pane isina chinhu PCB board inofanira kupinda mukati mePCB board yese isina chinhu uye kumisikidza magetsi ekubatanidza ane akasiyana conductive pateni akaturikidzana.Naizvozvo, sisitimu iyi yakanyatso kumisa abstract layer-yakawanda-layer. . . . . Kazhinji, mapedhi uye vias zvakarongwa pazvikamu zvakawanda.Kana iyi layer yakavharwa, mapads uye vias hazvigone kuratidzwa.

9. Drill Drawing (drilling layer): Chigadziko chekuchera chinopa ruzivo rwekuchera mukugadzirwa kwebhodhi risina chinhu rePCB (zvakadai semapedhi, vias zvinoda kucherwa).Altium inopa Drill gridi (mepu yemirairo yekuchera) uye Drill dhizaini (mepu yekuchera) maviri ekuchera akaturikidzana.

Mushure mekushama PCB bhodhi dhizaini yapera, iyo isina PCB bhodhi prototype inofanirwa kuitwa, uye zvakakoshawo kusarudza yakanaka isina.PCB bhodhi prototypefekitari.Huihe Circuits inotora zvinhu zveA-giredhi, masters nyanzvi isina PCB board yekugadzira tekinoroji, uye ine yakavimbika otomatiki kugadzira michina, yekuyedza uye inoshanda zvizere emuviri nemakemikari marabhoritari, ungave uri kuita zvekutaurirana michina, mota dzemagetsi, kutonga kwemaindasitiri, kana kurapwa. kurapwa.& kuchengetedzeka uye zvimwe zvigadzirwa zvemhando yepamusoro-tekinoroji, kana kuda mamwe akashama PCB board masevhisi, Huihe Circuits inokupa iwe akazara uye emhando yepamusoro hunyanzvi masevhisi.
