Ngenxa yokunyuka kwamva nje kweenkonzo zebhodi yesekethe ezifikelelekayo, abantu abaninzi abafunda iHackaday ngoku bafunda ubugcisa boyilo lwePCB.Kwabo basavelisa “iLizwe Molo” elilingana ne-FR4, zonke izinto ezilandelwayo zifika apho bezifanele ukuba khona, kwaye kwanele.Kodwa ekugqibeleni, uyilo lwakho luya kuba namabhongo ngakumbi, kwaye ngobu bunzima bongeziweyo buya kuza ngokwemvelo ukuqwalaselwa koyilo olutsha.Umzekelo, ukuthintela njani iPCB ekuzitshiseni kwizicelo eziphezulu zangoku?
Lowo ngumbuzo kanye uMike Jouppi awayefuna ukuwuphendula xa wayesindleke iNcoko yeHack kwiveki ephelileyo.Sisihloko asithatha nzulu kangangokuba waqala inkampani ebizwa ngokuba yi-Thermal Management LLC ezinikele ekuncedeni iinjineli nge-PCB yoyilo lobushushu.Ukwachophele uphuhliso lwe-IPC-2152, umgangatho wokulinganisa ngokufanelekileyo umkhondo webhodi yesekethe ngokusekwe kubungakanani bangoku obufunwa yibhodi.Lo ayingomgangatho wokuqala wokujongana nomba, kodwa ngokuqinisekileyo ngowona wangoku kwaye ubanzi.
Kwabaqulunqi abaninzi, kuqhelekile ukuba babhekiselele kwidatha eyaqala ngeminyaka yoo-1950s kwezinye iimeko, ngenxa nje yobulumko bokwandisa umkhondo wabo.Rhoqo oku kusekwe phezu kweengqikelelo athi uMike uthe uphando lwakhe lufumanise ukuba aluchanekanga, njengokucinga ukuba umkhondo wangaphakathi we-PCB udla ngokuba shushu kunomkhondo wangaphandle.Umgangatho omtsha wenzelwe ukunceda abaqulunqi baphephe le migibe enokubakho, nangona ebonisa ukuba kusengukulinganisa okungafezekanga kwehlabathi lokwenene;idatha ezongezelelweyo ezifana nokunyuka koqwalaselo kufuneka kuthathelwe ingqalelo ukuqonda ngcono iimpawu thermal ebhodini.
Kwanangomxholo ontsonkothileyo, kukho amacebiso afanelekileyo okufuneka uwagcine engqondweni.Ii-substrates zihlala zingasebenzi kakuhle ngokuthelekisa nobhedu, ngoko ke ukusebenzisa iinqwelomoya zobhedu zangaphakathi kunokunceda ukuqhuba ubushushu ngebhodi, utshilo uMike.Xa ujongana neendawo ze-SMD ezivelisa ubushushu obuninzi, ii-vias ezinkulu ezinobhedu zingasetyenziselwa ukwenza iindlela ezihambelanayo zokushisa.
Ngasekupheleni kwencoko, uThomas Shaddack wayenengcamango enika umdla: Ekubeni ukuxhathisa kwezalathi kunyuka ngobushushu, ngaba oku kunokusetyenziswa ukumisela iqondo lobushushu ngenye indlela ekunzima ukulinganisa imikhondo yePCB yangaphakathi?UMike uthi lo mbono ulungile, kodwa ukuba ufuna ukufumana ufundo oluchanekileyo, kufuneka ukwazi ukuchasana okuqhelekileyo komkhondo owulinganisayo.Into ekufuneka uyigcine engqondweni ukuya phambili, ngakumbi ukuba awunayo ikhamera eshushu ekuvumela ukuba ukrobe kumaleko angaphakathi ePCB yakho.
Ngelixa iincoko ze-hacker zihlala zingekho sesikweni, ngeli xesha siye saqaphela imiba ebuhlungu kakhulu.Abanye abantu baneengxaki ezithile kwaye bafuna uncedo.Kunokuba nzima ukusombulula zonke iinuances zemiba entsonkothileyo kwincoko kawonke-wonke, ke kwezinye iimeko, siyazi ukuba uMike unxibelelana ngokuthe ngqo nababekhona ukuze axoxe ngemiba kunye nabo bodwa.
Ngelixa singenakusoloko siqinisekisa ukuba uya kufumana olo hlobo lwenkonzo eyenzelwe umntu, sicinga ukuba bubungqina bamathuba othungelwano awodwa afumanekayo kwabo bathatha inxaxheba kwiNgxoxo yeHack kwaye ndiyabulela uMike ngokuya imayile eyongezelelweyo ukuqinisekisa ukuba wonke umntu uphendula eyona nto angayenza ngayo ingxaki.
I-Hack Chat yiseshoni yengxoxo ye-intanethi yeveki ebanjwe ziingcali ezikhokelayo ezivela kuzo zonke iimbombo ze-hardware ye-hacking field.Yindlela eyonwabisayo nengekho sikweni yokunxibelelana nabahlaseli, kodwa ukuba awukwazi ukuyenza, ezi zithuba zijongwayo kunye nemibhalo ethunyelwe kwiHackaday.io qiniseka ukuba awuphoswa.
Ke i-physics ye-1950s isasebenza, kodwa ukuba usebenzisa iileya ezininzi, kwaye ugalele ubhedu oluninzi phakathi, iileya zangaphakathi zisenokungabi ngaphezulu kwe-insulating.
