Ngenxa yokukhuphuka kwakamuva kwezinsizakalo zokukhiqiza zebhodi lesifunda ezithengekayo, abantu abaningi abafunda i-Hackaday manje bafunda ubuciko bomklamo we-PCB.Kulabo kini abasakhiqiza okuthi “Sawubona Umhlaba” okulingana no-FR4, yonke imikhondo ifika lapho kufanele ibe khona, futhi lokho kwanele.Kepha ekugcineni, imiklamo yakho izoba nesifiso sokuvelela, futhi ngalobu bunkimbinkimbi obengeziwe buzovela ngokwemvelo ukucatshangelwa kwemiklamo emisha.Isibonelo, ungayivimba kanjani i-PCB ekuzishiseni ezinhlelweni zamanje eziphezulu?
Yiwo kanye umbuzo uMike Jouppi abefuna ukuwuphendula lapho asingathe i-Hack Chat ngesonto eledlule.Kuyisihloko asithatha ngokungathi sína kangangokuthi waqala inkampani ebizwa ngokuthi i-Thermal Management LLC ezinikele ekusizeni onjiniyela nge-PCB design thermal.Uphinde waba ngusihlalo wokuthuthukiswa kwe-IPC-2152, indinganiso yokulinganisa ngokufanele ibhodi lesifunda ngokususelwa enanini lamanje ibhodi elidinga ukulithwala.Leli akulona izinga lokuqala lokubhekana nenkinga, kodwa ngokuqinisekile lingelesimanje kakhulu futhi liphelele.
Kubaklami abaningi, kuvamile kubo ukubhekisela kudatha ehlehlela emuva kuma-1950s kwezinye izimo, ngenxa nje yokuhlakanipha ukwandisa iminonjana yabo.Ngokuvamile lokhu kusekelwe emibonweni uMike athi ucwaningo lwakhe iluthole lunganembile, njengokuthatha ngokuthi iminonjana yangaphakathi ye-PCB ivame ukushisa kunezangaphandle.Izinga elisha lenzelwe ukusiza abaklami bagweme lezi zingibe ezingaba khona, nakuba eveza ukuthi kusewukulingisa okungaphelele komhlaba wangempela;idatha eyengeziwe njengokumiswa kokukhweza idinga ukucatshangelwa ukuze kuqondwe kangcono izici ezishisayo zebhodi.
Ngisho nendaba eyinkimbinkimbi kangaka, kunamacebiso asetshenziswa kabanzi okufanele uwakhumbule.Ama-substrates ahlala engasebenzi kahle ngokushisa okushisayo uma kuqhathaniswa nethusi, ngakho ukusebenzisa izindiza zethusi zangaphakathi kungasiza ekuqhubeni ukushisa ngebhodi, kusho uMike.Uma usebenzisana nezingxenye ze-SMD ezikhiqiza ukushisa okuningi, ama-vias amakhulu ahlanganiswe ngethusi angasetshenziswa ukudala izindlela ezishisayo ezihambisanayo.
Ngasekupheleni kwengxoxo, uThomas Shaddack waba nomcabango othakazelisayo: Njengoba ukumelana kweminonjana kukhula ngezinga lokushisa, ingabe lokhu kungasetshenziswa ukunquma izinga lokushisa kwezinye izinto okunzima ukuzikala zangaphakathi zePCB?UMike uthi umqondo uzwakala, kodwa uma ufuna ukuthola ukufundwa okunembile, udinga ukwazi ukumelana okulinganiselwe komkhondo owulinganisayo.Okuthile okufanele ukugcine engqondweni ukuya phambili, ikakhulukazi uma ungenayo ikhamera eshisayo ekuvumela ukuthi ulunguze izendlalelo zangaphakathi ze-PCB yakho.
Nakuba izingxoxo zama-Hacker ngokuvamile zingekho emthethweni, kulokhu siqaphele izinkinga ezibuhlungu kakhulu.Abanye abantu banezinkinga eziqondile futhi badinga usizo oluthile.Kungaba nzima ukuxazulula wonke ama-nuances wezinkinga eziyinkimbinkimbi engxoxweni yasesidlangalaleni, ngakho-ke kwezinye izimo, siyazi ukuthi uMike uxhumana ngqo nababekhona ukuze akwazi ukuxoxa ngezinkinga nabo ubuso nobuso.
Nakuba singeke sihlale siqinisekisa ukuthi uzothola lolo hlobo lwesevisi yomuntu siqu, sicabanga ukuthi kuwubufakazi bamathuba ayingqayizivele okuxhumana atholakala kulabo ababamba iqhaza ku-Hack Chat futhi sibonge uMike ngokuthatha elinye imayela ukuze aqinisekise ukuthi wonke umuntu uphendula okungcono kakhulu angaba nenkinga.
I-Hack Chat iyiseshini yengxoxo ye-inthanethi yamasonto onke ephethwe ochwepheshe abaholayo abavela kuwo wonke amagumbi omkhakha wokugebenga wehadiwe.Kuyindlela ejabulisayo nengakahleleki yokuxhumana nezigebengu ze-inthanethi, kodwa uma ungeke uphumelele, lokhu kubuka konke okuthunyelwe nokulotshiweyo okuthunyelwe ku-Hackaday.io kuqinisekisa ukuthi awuphuthelwa.
Ngakho-ke i-physics ye-1950s isasebenza, kodwa uma usebenzisa izendlalelo eziningi, futhi ujove ithusi eningi phakathi, izendlalelo zangaphakathi zingase zingabi ngaphezu kwe-insulating.
