Kwiminyaka yakutshanje, phantse umntu omnye unesixhobo sombane esingaphezulu kwesinye, kwaye ishishini lombane liphuhliswe ngokukhawuleza, eliye lakhuthaza nokunyuka ngokukhawuleza kweshishini lebhodi yesekethe yePCB. Kwiminyaka yakutshanje, abantu baneemfuno eziphezulu kunye eziphezulu zokusebenza kwiimveliso ze-elektroniki, eziye zakhokelela kwiimfuno eziphezulu kunye neziphezulu zomgangatho weebhodi zesekethe. Indlela yokwahlula umgangatho weebhodi zeesekethe ze-PCB iye yaba sisihloko sokunyusa inkxalabo.
Indlela yokuqala yokuhlola okubonakalayo, eyona nto iphambili ukujonga ukubonakala kwebhodi yesiphaluka. Eyona nto isisiseko ukujonga inkangeleko kukukhangela ukuba ubukhulu kunye nobukhulu bebhodi budibana nobukhulu kunye neenkcukacha ozifunayo. Ukuba akunjalo, kufuneka uphinde uyenze. Ukongeza, ngokhuphiswano oluqatha kwimarike yePCB, iindleko ezahlukeneyo ziyaqhubeka nokunyuka. Ukuze kuncitshiswe iindleko, abanye abavelisi bayaqhubeka nokunciphisa iindleko zezinto eziphathekayo kunye neendleko zokuvelisa. HB eqhelekileyo, cem-1, kunye cem-3 sheets ukusebenza kakubi kwaye kulula ukukhubaza, kwaye ingasetyenziselwa kuphela imveliso icala elinye, ngelixa fr-4 fiberglass panels zingcono kakhulu amandla kunye nokusebenza, kwaye zihlala zisetyenziswa. kwiiphaneli ezinamacala amabini kunye namacala amaninzi. Ukuveliswa kwe-laminates. Iibhodi ezenziwe ngamabhodi aphantsi zihlala zineenkcenkcesho kunye nemikrwelo, echaphazela kakhulu ukusebenza kweebhodi. Oku kwakhona apho kufuneka ugxininise ekuhloleni okubonakalayo. Ukongeza, nokuba i-inki yesigqubuthelo semaski ye-solder sicaba, nokuba kukho ubhedu oluveziweyo; nokuba isikrini sesilika sesilika sisusiwe, nokuba i-pad ivuliwe okanye ayikho nayo ifuna ukuhoywa.
Emva kokuba indlela yesibini kufuneka isetyenziswe, iphuma ngempendulo yokusebenza. Okokuqala, inokusetyenziswa ngokuqhelekileyo emva kokuba amacandelo efakwe. Oku kufuna ukuba ibhodi yesekethe ayinayo isiphaluka esifutshane okanye isiphaluka esivulekileyo. Umzi-mveliso unenkqubo yokuvavanya umbane ngexesha lokuvelisa ukufumanisa ukuba ibhodi inesekhethi evulekileyo okanye emfutshane. Nangona kunjalo, abanye abavelisi bebhodi basindisa Iindleko azikho kuvavanyo lombane (Ubungqina kwi-Jiezi, uvavanyo lombane lwe-100% luthenjisiwe), ngoko le ngongoma kufuneka icaciswe xa kuqinisekiswa ibhodi yesiphaluka. Emva koko khangela ibhodi yesiphaluka ukuveliswa kobushushu ngexesha lokusetyenziswa, ehambelana nokuba ububanzi bomgca / umgama womgca wesekethe ebhodini ifanelekile. Xa u-soldering i-patch, kuyimfuneko ukujonga ukuba i-pad iwele phantsi kweemeko eziphezulu zokushisa, okwenza kube nzima ukuthengisa. Ukongezelela, ukumelana nokushisa okuphezulu kwebhodi kubaluleke kakhulu. Isalathisi esibalulekileyo sebhodi lixabiso le-TG. Xa usenza ipleyiti, injineli kufuneka iyalele umzi-mveliso webhodi ukuba isebenzise ibhodi ehambelanayo ngokweemeko ezahlukeneyo zokusetyenziswa. Ekugqibeleni, ixesha eliqhelekileyo lokusetyenziswa kwebhodi likwangumqondiso obalulekileyo wokulinganisa umgangatho webhodi.
Xa sithenga iibhodi zesekethe, asikwazi ukuqala kwixabiso lodwa. Kufuneka kwakhona siqwalasele umgangatho weebhodi zeesekethe kwaye siqwalasele zonke iinkalo ngaphambi kokuba sithenge iibhodi zeesekethe ezingabizi.
