Ukukhiqizwa kwe-PCB
Amakhono okukhiqiza e-PCB athuthukisiwe, agxile ezintweni ezinembile kakhulu, ezinzima kakhulu, nezikhethekile, akhonza izimboni ezifana nocwaningo lwesayensi, i-RF, ezempi, ezokwelapha, amarobhothi, kanye ne-AI.
Kuyini ukukhiqizwa kwe-PCB (Printed Circuit Board)?
Ukukhiqizwa kwe-PCB (Ukukhiqizwa Kwebhodi Lesekethe Eliphrintiwe) kubhekisela enqubweni yokuguqula imiklamo yesekethe ibe amabhodi wesekethe asebenziseka ngempela.
Ukukhiqizwa Kwebhodi Lesekethe Eliphrintiwe
Umklamo kanye Nomphumela
Yakha imidwebo yesekethe kanye nezakhiwo usebenzisa isofthiwe ye-EDA efana ne-Altium ne-KiCad, bese ukhiqiza amafayela e-Gerber (aqukethe ulwazi lwesithombe lwesendlalelo ngasinye).
Ukulungiswa kwe-substrate
Khetha ama-laminate ambozwe ngethusi (njenge-FR-4), uwahlanze bese uwasika abe usayizi odingekayo.
Ukudluliswa kwesithombe
I-Lithography: I-Photoresist ifakwa ku-laminate embozwe ngethusi, futhi iphethini yomklamo idluliselwa ku-laminate ngokukhanya kwe-ultraviolet. Ukuqopha: Susa ithusi elingavikelwe ngezixazululo zamakhemikhali (njenge-ferric chloride) ukuze wakhe ama-circuit traces.
Ukubhoboza
Imigodi ibholwa ngemishini yokubhoboza yemishini noma ye-laser yokufaka izingxenye noma izingqimba ezixhumanisayo.
Ukufakwa kwethusi kanye nokwelashwa kwendawo
Ukuxhumeka kukagesi kufezwa ngokufaka ithusi odongeni lwembobo ngokusebenzisa i-electroplating. Ukwelashwa kwendawo (njengokufafaza ngethini, i-gold plating, i-OSP) kuvimbela i-oxidation futhi kuthuthukisa ukunamathela.
Ukuphrinta kwesikrini kanye nemaski yokubopha
Faka ungqimba lwemaski yokusoda (ngokuvamile oluhlaza okotshani) ukuze uvikele futhi uvikele ama-trace, bese uvala isivikelo se-silk-screen ukuhlonza ingxenye.
Ukuhlolwa Nokuhlolwa
Yenza izivivinyo zikagesi (njengokuhlolwa kwe-flying probe) kanye nokuhlolwa okubonakalayo ukuqinisekisa ukuthi azikho iziphambeko ezifana nama-short circuits noma ama-open circuits.
Ukwakha nokupakisha
Sika ube yisimo sokugcina kanye nephakheji ukuze uthunyelwe.
Ubuchwepheshe obuyinhloko nezinhlobo
Ukuhlukaniswa kobuchwepheshe
*Iphaneli enohlangothi olulodwa: Uhlangothi olulodwa kuphela olunezisekethe.
*Iphaneli enezinhlangothi ezimbili: Izinhlangothi ezimbili zesekethe zixhunywe nge-vias.
*Amabhodi anezingqimba eziningi (izingqimba ezingu-4-100+): esetshenziselwa amadivayisi ayinkimbinkimbi (njengamafoni eselula, amaseva).
Ubuchwepheshe obuthuthukisiwe
*Ibhodi le-HDI: Ukuxhumana okunobuningi obukhulu, ama-via amancane kanye namasekethe amancane.
*Ibhodi eguquguqukayo: Iyagobeka futhi isetshenziswa kumadivayisi agqokwayo, njll.
*I-substrate yensimbi: Ukushabalalisa ukushisa okunamandla, okusetshenziswa kuma-LED kanye nezinsiza zikagesi.
