Chifukwa cha kukwera kwaposachedwa kwa ntchito zotsika mtengo zopangira ma board, anthu ambiri omwe akuwerenga Hackaday akuphunzira luso la mapangidwe a PCB.Kwa inu omwe mukupangabe "Moni World" yofanana ndi FR4, zotsatizana zonse zikufika pomwe zikuyenera kukhala, ndipo ndizokwanira.Koma pamapeto pake, mapangidwe anu adzakhala olakalaka kwambiri, ndipo ndizovuta zowonjezera izi mwachilengedwe zimadza ndi malingaliro atsopano.Mwachitsanzo, mungapewe bwanji PCB kuti isadziwotchere pamapulogalamu apamwamba kwambiri?
Ndilo ndendende funso Mike Jouppi ankafuna kuthandiza kuyankha pamene anachititsa Hack Chat sabata yatha.Ndi mutu womwe amauona mozama kwambiri mpaka adayambitsa kampani yotchedwa Thermal Management LLC yodzipereka kuthandiza mainjiniya opanga matenthedwe a PCB.Adatsogozanso chitukuko cha IPC-2152, muyezo wamasanjidwe oyenera a board board kutengera kuchuluka kwa zomwe gulu liyenera kunyamula.Uwu si muyeso woyamba wothana ndi vutoli, koma ndithudi ndi wamakono komanso wokwanira.
Kwa okonza ambiri, ndizofala kwa iwo kuti atchule zomwe zidachitika m'zaka za m'ma 1950 nthawi zina, chifukwa chanzeru kuti awonjezere mawonekedwe awo.Nthawi zambiri izi zimatengera malingaliro omwe Mike akuti kafukufuku wake adapeza kuti ndi zolakwika, monga kuganiza kuti mawonekedwe amkati a PCB amakhala otentha kuposa mawonekedwe akunja.Muyezo watsopanowu wapangidwa kuti uthandize opanga kupeŵa misampha yomwe ingakhalepo, ngakhale akuwonetsa kuti akadali kuyerekezera kopanda ungwiro kwa dziko lenileni;zina zowonjezera monga kuyika kasinthidwe ziyenera kuganiziridwa kuti mumvetse bwino za kutentha kwa bolodi.
Ngakhale ndi nkhani yovutayi, pali mfundo zina zofunika kuzikumbukira.Ma substrates nthawi zonse amakhala ndi kutentha kosakwanira poyerekeza ndi mkuwa, kotero kugwiritsa ntchito ndege zamkuwa zam'kati kungathandize kutentha kudzera pa bolodi, Mike adati.Pochita ndi magawo a SMD omwe amapanga kutentha kwambiri, ma vias akuluakulu amkuwa angagwiritsidwe ntchito kupanga njira zofananira zotentha.
Chakumapeto kwa macheza, a Thomas Shaddack anali ndi lingaliro lochititsa chidwi: Popeza kukana kwa mayendedwe kumawonjezeka ndi kutentha, kodi izi zitha kugwiritsidwa ntchito kudziwa kutentha kwamtundu wina wovuta kuyeza wamkati wa PCB?Mike akuti lingalirolo ndi lomveka, koma ngati mukufuna kuwerengera molondola, muyenera kudziwa kukana mwadzina komwe mukutsata.Chinachake choyenera kukumbukira kupita patsogolo, makamaka ngati mulibe kamera yotentha yomwe imakulolani kuyang'ana mkati mwa PCB yanu.
Ngakhale macheza owononga nthawi zambiri amakhala osakhazikika, nthawi ino tidawona zovuta zina.Anthu ena ali ndi mavuto enieni ndipo amafunikira thandizo.Zingakhale zovuta kuthetsa mikangano yonse yazovuta pazokambirana zapagulu, kotero nthawi zina, tikudziwa kuti Mike amalumikizana mwachindunji ndi omwe akupezekapo kuti athe kukambirana nawo payekhapayekha.
Ngakhale sitingatsimikizire nthawi zonse kuti mupeza mtundu wautumiki wokhazikika, tikuganiza kuti ndi umboni wa mwayi wapadera wapaintaneti womwe ukupezeka kwa omwe akuchita nawo Hack Chat ndikuthokoza Mike chifukwa chopita mtunda wowonjezera kuonetsetsa kuti aliyense akuyankha bwino angathe kubvuta.
Hack Chat ndi nthawi yochezera pa intaneti ya mlungu ndi mlungu yomwe imachitidwa ndi akatswiri otsogola ochokera m'makona onse a Hardware.Ndi njira yosangalatsa komanso yosavomerezeka yolumikizirana ndi achiwembu, koma ngati simungathe, izi mwachidule zolemba ndi zolemba zomwe zidatumizidwa ku Hackaday.io onetsetsani kuti simukuphonya.
Kotero fizikiki ya m'ma 1950 ikugwirabe ntchito, koma ngati mumagwiritsa ntchito zigawo zambiri, ndikulowetsa mkuwa wambiri pakati, zigawo zamkati sizingakhale zotetezera.
