Dhizaini uye Kugadzira PCB Yesimba Repamusoro
Dhizaini yePCB ine simba guru inoda kuti sarudzo dzemagetsi, dzekupisa, dzemakanika, uye dzekugadzira dzishande pamwe chete. Kuwanda kwemagetsi, nzvimbo yemagetsi, kuyerera kwekupisa, kuiswa kwezvikamu, uye kufukidza bvunzo zvese zvinopesvedzera kana bhodhi richishanda zvakanaka pakushandiswa kwaro.
Gwaro iri rinotsanangura zvinhu zvinodzora zvinoshanda zvinoita kuti kugadzirwa nekugadzwa kwePCB ine simba guru kuve nyore kusimbisa nekudzokorora.

Tsanangura Zvinodiwa Nesimba
Nyora nguva inoenderera mberi uye yepamusoro, huwandu hwemagetsi, frequency yekuchinja, mamiriro ekutadza, tembiricha yemhepo, nzira yekutonhodza, uye duty cycle inotarisirwa. Izvi zvinoisa zvinhu zvinosarudza saizi yemutyairi, nzvimbo, kusarudzwa kwezvinhu, kubviswa kwezvikamu, uye hurongwa hwekuyedza.
Usaite saizi yePCB chete kubva pamutoro wepakati. Kutanga, kuwandisa kwenguva pfupi, uye mamiriro ekushanda asina kujairika zvinogona kuisa miganhu chaiyo yekupisa nemagetsi.
Nzira Dzazvino uye Dhizaini Yemhangura
Upamhi hwetrace, ukobvu hwemhangura, via count, connector rating, uye solder-joint geometry zvese zvinokanganisa kugona kwe current. Mepu ye full current loop, kusanganisira returns, kuti uone zvipingamupinyi pane kutarisa pane trace imwe chete yakafara.
Kana panodiwa nzira dzemhangura dzakakora kana dzakafanana, simbisai kuti dzinofanira kuchekwa uye kuti dzakabviswa pakugadzira zvinhu nemugadziri panguva yekuongorora DFM.
Thermal Management
Kupisa kunofanira kufamba kubva panobva zvinhu kuenda kumhangura, mavias, zvinhu zvinoshandisa thermal interface, ma heat sinks, zvinhu zvinovhara, kana kuyerera kwemhepo. Shandisa ongororo ye thermal uye kuyerwa kuti uwane nzvimbo dzinopisa dzakatenderedza ma power semiconductors, ma inductors, ma resistors, uye ma connectors.
Ma "thermal vias" uye "copper drips" zvinobatsira chete kana paine nzira yakakwana yekuenda kunzvimbo inotonhorera. Chengeta zvinhu zvinonzwa kupisa zvakanyanya kure nenzvimbo dzinopisa zvakanyanya kana zvichibvira.
Zvinhu, Kukweva, uye Kubvisa Zvinhu Zvakagadzirwa
Sarudza laminate, ukobvu hwe dielectric, chifukidziro che solder, uye kupedzisa kwenzvimbo yemagetsi uye maitiro ekubatanidza. Zvinodiwa pakubvisa zvinhu zvinoenderana nemagetsi, mwero wekusvibiswa, kufukidza, kukwirira, uye mwero wezvigadzirwa zvinoshanda.
Nyora mitemo inodiwa muhurongwa hwemarongerwo nedhirowa kuitira kuti shanduko dzenzira kana mapaneru dzisazokanganisa gare gare.
Kufunga Nezvekuungana kwePCB Yesimba Repamusoro
Nzvimbo dzine kupisa kwakanyanya dzinoda nzira yekunyungudutsa mvura inokwanisa kunyorovesa pasina kupisa zvikamu zviri pedyo. Kuiswa kwezvikamu, dhizaini yestencil, chimiro chekuyererazve, kunyungudutsa kwekusarudza, uye rutsigiro rwemakanika zvinofanirwa kuongororwa senzira imwe chete yekubatanidza.
Ma terminal makuru nezvikamu zvinorema zvinogona kuda kuchengetwa kwemuchina. Mapedhi avo, saizi dzema drill, uye ma solder fillets anofanirwa kuongororwa kuti aonekwe kuti anodedera here kana kuti anotakurwa sei.
Kuongorora uye Kusimbiswa
Kuongorora kunofanirwa kuratidza polarity, mhando yesolder, daro rakakosha rekupatsanurwa, uye mhando yemajoini ane simba rakawanda. Kuedza kwekushanda kunogona kusanganisira kuyedzwa kwemutoro, kuyerwa kwekupisa, kutarisa insulation, uye kuongororwa kwemhinduro dzezvikanganiso kwakakodzera chigadzirwa.
Miganhu yekugamuchirwa kwekugadzirwa inofanira kunyorwa kuitira kuti zvinodiwa zvakafanana zvishandiswe pakuvaka kwekutanga uye kudzokorora.
Rutsigiro rwePCB Rune Simba Rakakwirira NeHighleap
Highleap Electronics inogona kuongorora data rePCB rine simba guru kuti ione njodzi dzekugadzira nekugadzira zvinhu zvisati zvagadzirwa. Kupa nzira dziripo, zvinangwa zvekupisa, zvinodiwa pakuunganidzwa kwezvinhu, uye zvinotarisirwa pakuyedza zvinobvumira ongororo yekugadzirwa kwezvinhu inobatsira zvikuru.
Kuti muone kana zvinhu zvichigona kugadzirwa, kumbirai mutengo wePCB une mafaira eGerber, BOM, mifananidzo, uye zvinodiwa nemagetsi.
