Tikugashirei kune yedu yakazara gwara rekuita PCB (Yakadhindwa Circuit Board)!Mune ino blog post, tichakufambisa iwe kuburikidza nekugadzira PCB kubva kutanga, tichipa nhanho-ne-nhanho mirairo uye anobatsira mazano munzira.Kunyangwe iwe uri hobbyist, mudzidzi, kana anoda zvemagetsi enthusiast, gwara iri rakagadzirirwa kukubatsira iwe kubudirira kugadzira nekugadzira ako ePCB.Saka, ngatitarisei zvakadzama!
1. Nzwisisa izvo zvekutanga zvePCB dhizaini:
Tisati tapinda mukugadzira maitiro, zvakakosha kuti tive nekunzwisisa kwakasimba kweiyo yekutanga PCB dhizaini.Iva kujairana neanodikanwa maturusi esoftware, senge EDA (Electronic Design Automation) software, iyo inokugonesa iwe kugadzira uye kuronga dhizaini yedunhu.
2. Magadzirirwo ehurongwa:
Tanga nekufungidzira dunhu rako uchishandisa schematic.Iyi nhanho yakakosha inoita kuti iwe ugone kuronga kuti chikamu chimwe nechimwe chichaiswa papi pabhodhi.Muchikamu chese ichi, ita shuwa kuti chirongwa chinotevera maitiro akanakisa ekumiririra kwakajeka uye kwakapfupika.
3. Gadzira PCB dhizaini:
Kana iyo schematic yagadzirira, inoendeswa kuPCB dhizaini software.Zvikamu zvinoiswa pabhodhi kutanga, uchichenjerera kuzvironga zvakaringana kuti zvifambe zvakanaka.Rangarira kufunga zvinhu zvakaita senge saizi yechikamu, kubatana, uye kupisa kwekupisa.
4. Nzira:
Kufambisa kunosanganisira kugadzira zviteshi kana nzira dzekufambisa dzekubatanidza zvikamu zvakasiyana paPCB.Nyatsoona mafambisirwo enzira yega yega, uchifunga nezvezvinhu zvakaita sechiratidzo chekuvimbika, kugovera kwemagetsi, uye ndege dzepasi.Nyatsoteerera kumitemo yemvumo uye ita shuwa kuti madhizaini ako anosangana neyakajairwa kugadzira kushivirira.
5. Kusimbisa dhizaini:
Dhizaini yako inofanirwa kunyatso kusimbiswa usati waenderera mberi nekugadzira maitiro.Ita Dhizaini Rule Tarisa (DRC) uye tarisa dhizaini yako kubva kumakona ese.Ita shuwa kuti maronda akapatsanurwa zvakanaka uye hapana zvingangoita zvikabudura.
6. Nzira yekugadzira:
Paunenge uchinge wagutsikana nePCB yako dhizaini, maitiro ekugadzira anogona kutanga.Tanga nekuendesa dhizaini yako kubhodhi yakavharwa nemhangura uchishandisa pre-yakavharwa PCB kana toner nzira yekuendesa.Etch bhodhi kuti ubvise mhangura yakawandisa, uchisiya chete matani anodiwa uye mapedhi.
7. Kuchera nekuputira:
Uchishandisa diki diki, chera makomba munzvimbo dzakatarwa paPCB.Maburi aya anoshandiswa kukwirisa zvinhu nekugadzira kubatanidza magetsi.Mushure mekuchera, maburi anoputirwa nehutete hwakatsetseka hwezvinhu conductive semhangura kuti iwedzere conductivity.
8. Welding components:
Iye zvino yave nguva yekuunganidza zvinhu paPCB.Solder chimwe nechimwe chikamu munzvimbo, kuve nechokwadi kurongeka kwakaringana uye yakanaka solder majoini.Inokurudzirwa kushandisa simbi yakanyungudutswa ine simba rakakodzera uye tembiricha kudzivirira zvikamu uye PCB.
9. Kuedza uye Kugadzirisa Matambudziko:
Mushure mekutengesa kwapera, zvakakosha kuti uedze mashandiro ePCB.Shandisa multimeter kana yakakodzera bvunzo midziyo kutarisa kubatana, voltage mazinga uye zvinogona kukanganisa.Gadzirisa chero matambudziko anomuka uye gadzirisa zvinodiwa kana kutsiva zvikamu.
mukupedzisa:
Makorokoto!Iwe uchangodzidza kugadzira PCB kubva kutanga.Nekutevera gwara rakazara iri, iwe unogona ikozvino kugadzira, kugadzira uye kuunganidza ako akadhindwa edunhu mabhodhi.Kugadzirwa kwePCB inzira inonakidza asi inonetsa inoda kutarisisa kune zvakadzama, moyo murefu uye ruzivo rwemagetsi.Rangarira kuedza uye kubvuma kudzidzira curve.Nekudzidzira, iwe uchawana chivimbo uye unokwanisa kugadzira inowedzera kuomarara PCB dhizaini.Kufara PCB kugadzira!
