Yazisa:
Ukwakha ibhodi yesekethe yeprototype linyathelo elibalulekileyo kwinkqubo yophuhliso lwemveliso.Ivumela iinjineli, abaqulunqi kunye nabavelisi ukuba bavavanye kwaye basulungekise izimvo zabo ngaphambi kokuba baqhubeke nemveliso.Nangona kunjalo, kukho iimpazamo eziqhelekileyo ezinokuthintela impumelelo yebhodi yakho yeprototype.Kule posi yebhlog, siza kuxoxa ngezi mpazamo kwaye sinike iingcebiso malunga nokuba ungaziphepha njani ukuze siqinisekise inkqubo egudileyo nenempumelelo ye-PCB yokuchwetheza.
1. Ukungahoywa kwesicwangciso esifanelekileyo kunye noyilo
Enye yezona mpazamo ezinkulu xa kusakhiwa ibhodi yesekethe yeprototype kukutyeshela ucwangciso olululo kunye noyilo.Ukungxamela kwisigaba sokwenza umboniso ngaphandle kwesicwangciso esicingisiswe kakuhle kunokukhokelela kwinkcitho yexesha, umzamo, kunye nezixhobo.Phambi kokuba uqale ukwakha, kubalulekile ukwenza isikimu esicacileyo, uchaze uyilo lwecandelo, kwaye ubeke uyilo olubanzi lwesekethe.
Ukunqanda le mpazamo, thatha ixesha lokucwangcisa kwaye uyila ibhodi yakho yeprototyping ngocoselelo.Oku kubandakanya ukuqonda iinjongo zesekethe, ukukhetha amacandelo afanelekileyo, kunye nokudala iskimu esineenkcukacha.Ukusebenzisa i-software yoyilo ye-PCB kunokunceda ukulungelelanisa inkqubo yocwangciso kwaye kuthintelwe iziphene zoyilo ezinokubakho.
2. Uyilo lwesekethe lunzima kakhulu
Ukugqithiswa koyilo lwesekethe yenye impazamo eqhelekileyo enokukhokelela ekungaphumelelini kwebhodi yeprototype.Nangona kungokwemvelo ukufuna ukubandakanya zonke iimpawu kunye nokusebenza kuyilo lwakho lokuqala, ukwenza njalo kunokwenza ibhodi ibe nzima kwaye kunzima ukuyihlanganisa.Oku kwandisa umngcipheko weempazamo kwaye kunciphisa ithuba lokuphumelela kweprototype.
Ukuze ugweme ukugqithisa uyilo lwesekethe yakho, gxininisa kwiinjongo eziphambili zeprototype yakho.Qala nge-minimalist approach kwaye ngokuthe ngcembe wandise ubunzima xa kuyimfuneko.Ukulula akuphuculi nje kuphela amathuba okwakhiwa okuphumelelayo, kugcina ixesha kunye nokunciphisa iindleko.
3. Ukungaqwalaselwanga ulawulo lwe-thermal
Ulawulo lwe-Thermal luhlala lungahoywa xa kwakhiwa iibhodi zeesekethe zeprototype, ezikhokelela ekushiseni okuphezulu kunye nokusilela kwesixhobo.Ukungaqwalaselwa ngokwaneleyo kokupholisa kunokukhokelela ekuthotyweni komsebenzi jikelele kwaye, kwezinye iimeko, umonakalo ongenakulungiseka kumalungu.
Ukuze ugweme le mpazamo, qwalasela izinto ezifana nokubekwa kwecandelo, i-heat sinks, kunye nokuhamba komoya ukuqinisekisa ulawulo olufanelekileyo lwe-thermal.Ukusasazwa ngokufanelekileyo kwamacandelo okuvelisa ukushisa kunye nokusetyenziswa kwe-thermal vias okanye iipads kunokunceda ukutshabalalisa ubushushu ngokufanelekileyo kwaye kuthintele naziphi na iingxaki ezinokubakho.
4. Ukungahoyi uvavanyo kunye nokuqinisekiswa
Enye impazamo enkulu kukutyeshela ukuvavanya ngokucokisekileyo kunye nokuqinisekisa ibhodi yeprototype.Ukutsiba eli nyathelo libalulekileyo kwandisa umngcipheko wokungahoyi iziphene zoyilo, imiba yokusebenza, kunye nemiba yokuhambelana.Uvavanyo olubanzi aluqinisekisi kuphela ukusebenza kwebhodi, kodwa kunye nokuzinza kwayo phantsi kweemeko ezahlukeneyo.
Ukuze ugweme le mpazamo, bandakanya uvavanyo olwaneleyo kunye neenkqubo zokuqinisekisa kulo lonke isigaba seprototyping.Yenza uvavanyo olusebenzayo, uvavanyo lwemfezeko yomqondiso, kunye novavanyo lokusingqongileyo ukuqinisekisa ukuthembeka kunye nokuqina kweprototype.Eli nyathelo linceda ekuchongeni iingxaki ezinokwenzeka kwangoko kwaye livumela uhlengahlengiso oluyimfuneko ukuba lwenziwe ngaphambi kokungena kwimveliso.
5. Ungaluhoyi uyilo lokwenziwa kwezinto
Uyilo lwe-manufacturability (DFM) luhlala lungahoywa ngexesha lesigaba seprototyping, ekhokelela kubunzima kunye nokwanda kweendleko ngexesha lokuvelisa umthamo.Ukungahoyi iimfuno zokuvelisa kunye nezithintelo kunokubangela iziphene zokuyila, ukukhetha izinto ezingathandekiyo, kunye neenkqubo zokuhlanganisa ezingasebenzi kakuhle.
Ukunqanda le mpazamo, ziqhelanise nemigaqo kunye nezikhokelo ze-DFM.Lungiselela uyilo ukuze kube lula ukwenza, khetha amacandelo angaphandle kweshelufu, kwaye uqwalasele inkqubo yokuvelisa kunye nendibano kulo lonke inqanaba leprototyping.Ukusebenzisana nabavelisi kwangethuba kunokubonelela ngezimvo ezixabisekileyo kunye neengcebiso ezinokubakho zokonga iindleko.
Ukuququmbela:
Ukwakha iibhodi zeesekethe zeprototype yinxalenye ebalulekileyo yenkqubo yophuhliso lwemveliso.Unokuqinisekisa inkqubo yeprototyping eyimpumelelo ngokuphepha iimpazamo eziqhelekileyo ezifana nokungahoyi ukucwangciswa okufanelekileyo, ukuyila ngokugqithiseleyo, ukungahoywa kolawulo lwe-thermal, ukuphosa uvavanyo, kunye nokutyeshela ukuyila ukuveliswa kokwenziwa.Ukuthatha ixesha lokucwangcisa, ukuyila, ukuvavanya, kunye nokwandisa iibhodi zeprototype kuya kwenza utshintsho kwimveliso lusebenze ngakumbi kwaye lungabizi kakhulu.Khumbula, ibhodi yeprototype eyenziwe kakuhle lilitye lokunyathela ukuya kwimveliso eyimpumelelo, elungele imarike.
