1. Dhirowa PCB redunhu bhodhi:
2. Gadzirisa kudhinda chete TOP LAYER uye kuburikidza ne layer.
3. Shandisa laser printer kudhinda pane thermal transfer paper.
4. Iyo thinnest yemagetsi yedunhu yakaiswa pane ino redunhu board ndeye 10mil.
5. Iyo yeminiti imwe chete yekugadzira ndiro inotangira kubva pamufananidzo wakasviba-uye-chena wedunhu remagetsi rakadhindwa pane thermal transfer paper by laser printer.
6. Kune rimwe-sided redunhu mabhodhi, imwe chete inokwana.
Wobva waisungirira kune yakakodzera saizi yemhangura yakapfeka laminate, kupisa uye kudzvanya muchina wekutamisa kupisa, masekondi makumi maviri kupedzisa kupisa kupisa.Bvisa copper clad laminate uye ufukure iyo yekupisa yekufambisa bepa, iwe unogona kuona yakajeka yedunhu diagiramu pane yemhangura yakapfeka laminate.
7. Zvadaro isa copper clad laminate mu oscillating corrosion tank, uchishandisa yakasanganiswa inoparadza mhinduro ye hydrochloric acid uye hydrogen peroxide, zvinongotora masekondi gumi nemashanu kuti ubvise yakawandisa mhangura.
Chiyero chakakodzera che hydrochloric acid, hydrogen peroxide, uye yakakwirira-speed oscillating corrosion tank ndiwo makiyi ekuwana nekukurumidza uye kwakakwana kukora.
Mushure mekutsvaira nemvura, bhodhi redunhu rakasvibiswa rinogona kutorwa kunze.Hwerengedzo yemasekonzi 45 akapfuura panguva iyi.Usambofa wakabata zvinwiwa zvinoodza zvakawandisa zvisingaite.Kana zvisina kudaro, kurwadziwa kuchayeukwa kwehupenyu hwose.
8. Shandisa acetone zvakare kupukuta toner nhema.Nenzira iyi, yekuyedza PCB board inopedzwa.
9. Shandisa flux kumusoro kwebhodhi redunhu
10. Shandisa yakafara blade solder simbi kuisa redunhu bhodhi kuti nyore soldering gare gare.
11. Bvisa solder flux uye shandisa soldering flux kumudziyo wepamusoro wegomo kuti upedze kutengesa kwechigadzirwa.
12. Pamusana pe-pre-coated solder, zviri nyore kutengesa chigadzirwa.
13. Mushure mekutengesa, chenesa bhodhi redunhu nemvura yekugeza.
14. Chikamu chebhodhi redunhu.
15. Kune akawanda mapfupi waya pabhodhi redunhu.
16. Iyo pfupi wiring inopedzwa ne0603, 0805, 1206 zero ohm resistance.
17. Mushure memaminitsi gumi, bhodhi redunhu rakagadzirira kuedza.
18. Circuit board pasi pekuedzwa.
19. Complete redunhu debugging.
Iyo yeminiti imwe yekupisa ndiro yekugadzira nzira inogona kuita kugadzirwa kwehardware kuve nyore sekuronga software.Mushure meyedzo yedunhu block yapedzwa, kugadzirwa kwedunhu kunozopedzwa uchishandisa nzira yekugadzira ndiro.
Iyi nzira haisi kungochengetedza mari yekuedza, asi inonyanya kukosha, inochengetedza nguva.Pfungwa yakanaka, kana iwe ukamirira zuva kana maviri usati wawana bhodhi redunhu zvinoenderana neyakajairwa yekugadzira ndiro, kufara kuchapedzwa.
