Kule mihla yedijithali, iikhibhodi ziye zaba sisixhobo esibalulekileyo sonxibelelwano, inkqubo, kunye nemidlalo. Uyilo oluntsonkothileyo lwekhibhodi lubandakanya amacandelo ahlukeneyo, enye yezona zinto zibaluleke kakhulu yibhodi yesekethe eprintiweyo (PCB). Ukuqonda indlela yokuyila i-PCB yebhodi yezitshixo kubalulekile kwii-hobbyists kunye neengcali ngokufanayo. Kwesi sithuba sebhlog, siza kungena kwihlabathi elintsonkothileyo loyilo lwePCB yebhodi yezitshixo ukuze sikubonelele ngesikhokelo esibanzi sokwenza olu hlobo lobugcisa.
1. Qonda iziseko zoyilo lwePCB yebhodi yezitshixo:
Phambi kokuphonononga iinkcukacha ezintsonkothileyo yoyilo PCB keyboard, kubalulekile ukuba uqhelane nemigaqo esisiseko. I-PCB yebhodi yezitshixo isebenza njenge hub esembindini edibanisa iiswitshi ezahlukeneyo, iidiode, kunye namanye amacandelo. Ibonelela ngedatha yezitshixo kwikhompyuter, ivumela umsebenzisi ukuba angenise imiyalelo. Ukuqonda izicwangciso zombane, tshintsha uyilo lwematrix, kunye nodibaniso lwe-firmware lubalulekile ekudaleni i-PCB yebhodi yezitshixo esebenzayo nesebenza ngokupheleleyo.
2. Khetha amacandelo afanelekileyo:
Ukukhetha amacandelo achanekileyo kwi-PCB yebhodi yakho kubalulekile ekuqinisekiseni ukuthembeka nokusebenza kwayo. Ukukhethwa ngokufanelekileyo kokutshintsha, i-diodes, i-capacitors, i-resistors, kunye ne-microcontrollers idlala indima ebalulekileyo ekunqumeni amava okuchwetheza jikelele kunye nokusebenza. Ukuphanda kunye nokulinga ngamacandelo ahlukeneyo kuya kukunceda ufumane indibaniselwano efanelekileyo kwiimfuno zakho ezithile.
3. Cwangcisa uyilo lwebhodi yezitshixo:
Uyilo lwekhibhodi yinkalo ebalulekileyo yoyilo lwePCB. Ukumisela inani lezitshixo, indawo yazo, kunye nesakhiwo esipheleleyo soyilo lwebhodibhodi kufuneka siqwalaselwe ngononophelo. Izinto ezifana ne-ergonomics, ukufikeleleka okuphambili kunye neendlela zokusetyenziswa kufuneka ziqwalaselwe ngexesha lokucwangcisa. Izixhobo ezifana ne-Keyboard Layout Editor (i-KLE) inganceda ukubona kunye nokugqibezela uyilo lobeko lwebhodi yezitshixo.
4. Uyilo lwesekethe:
Nje ukuba ubeko lwebhodi yezitshixo lugqityiwe, inyathelo elilandelayo kukuyila iskimu sesekethe. Ukudala iskimu esichanekileyo sesekethe kubandakanya ukudibanisa iiswitshi, iidiode, kunye namanye amacandelo ngendlela enengqiqo. Izixhobo ezifana ne-EAGLE, i-KiCad okanye i-Altium Designer inokunceda ukudala i-schematics yesekethe ekhangayo kunye nokulungelelaniswa kakuhle.
5. Phumeza uyilo lwePCB:
Emva kokugqiba iskimu sesekethe, inyathelo elilandelayo kukuguqulela kuyilo lwePCB lokwenyani. Sebenzisa isoftware yoyilo yePCB efana ne-EAGLE, iKiCad okanye iAltium Designer ukuguqula ischematics sesekethe ibe yiPCB uyilo. Ukubekwa kwecandelo ngokuchanekileyo, umzila osebenzayo, kunye nokubambelela kwizikhokelo zoyilo kubalulekile. Ukunikela ingqalelo kwizinto ezifana nengxolo yombane, iinqwelomoya zomhlaba, kunye nokutshatyalaliswa kobushushu kuya kuqinisekisa ukuba iPCB yebhodibhodi yomelele kwaye ithembekile.
6. Vavanya kwaye uphindaphinde:
Nje ukuba uyilo lwePCB lugqityiwe, kubalulekile ukuvavanya iprototype ngocoselelo. Ukujonga ukusebenza, ukuchaneka kwe-keystroke, kunye nokunyaniseka komqondiso kuya kunceda ukuchonga iingxaki ezinokubakho. Ukuphinda uyilo olusekwe kwingxelo yomsebenzisi kunye nohlalutyo lokusebenza kubalulekile ekuphumezeni i-PCB yebhodi yezitshixo ekumgangatho ophezulu.
Ukuyila iPCB yebhodi yinkqubo entsonkothileyo kodwa enomvuzo. Ubuchule bolu hlobo lobugcisa kufuna ukuqonda okunzulu kwamacandelo ebhodi yezitshixo, uyilo lwesekethe, kunye nengqalelo yobuchule kwiinkcukacha. Ngokulandela la manyathelo achazwe kwesi sikhokelo sibanzi, ungaqala uhambo lokuyila eyakho ikhibhodi yePCB yesiko. Ke zilungiselele, vula ubuchule bakho kwaye uvumele iminwe yakho idanise kowakho umsebenzi wobugcisa!
