Ubuchwepheshe be-Thru-hole, obubizwa nangokuthi “nge-thru-hole”, bubhekisela ohlelweni lokukhweza olusetshenziselwa izingxenye ze-elekthronikhi ezibandakanya ukusetshenziswa kwemikhondo ezingxenyeni ezifakwa emigodini ebhojwe kumabhodi esekethe aphrintiwe (PCB) futhi athengiswa kumaphedi ohlangothini oluphambene kungaba ngokuhlanganisa ngesandla/ukusoda okwenziwa ngesandla noma ngokusetshenziswa kwemishini yokukhweza ezenzakalelayo.
Ngabasebenzi abaqeqeshiwe abangaphezu kuka-80 be-IPC-A-610 abahlanganiswe ngesandla kanye nokusoda izingxenye, siyakwazi ukunikeza imikhiqizo engaguquki yekhwalithi ephezulu phakathi nesikhathi sokuhola esidingekayo.
Ngazo zombili i-lead ne-lead soldering yamahhala asinazo izinqubo zokuhlanza ezihlanzekile, ezincibilikayo, ze-ultrasonic kanye nezamanzi ezitholakalayo.Ngaphezu kokunikeza zonke izinhlobo zokuhlanganisa imbobo, i-Conformal coating ingatholakala ukuze kuqedwe okokugcina umkhiqizo.
Lapho benza i-prototyping, onjiniyela bokuklama bavame ukukhetha ukukhudlwana ngokusebenzisa izimbobo ukuze bafake izinto ezingaphezulu ngenxa yokuthi bangasetshenziswa kalula namasokhethi e-breadboard.Kodwa-ke, imiklamo enesivinini esiphezulu noma yamaza aphezulu ingase idinge ubuchwepheshe be-SMT ukuze kuncishiswe i-inductance ne-capacitance ezintanjeni, ezingakhinyabeza ukusebenza kwesekethe.Ngisho nasesiteji se-prototype somklamo, umklamo ohlangene kakhulu ungase unqume ukwakheka kwe-SMT.
Uma kukhona olunye ulwazi olunentshisekelo pls zizwe ukhululekile ukusithinta.
