Ukuqhekeka kwejoyinti le-solder endaweni ehlanganiswe ngokuhlanganyela akuvamile;kuMfanekiso 1 i-solder joint isebhodini elihlangothini olulodwa.Ijoyinti lihlulekile ngenxa yokunwetshwa nokufinyela komthofu kujoyinti.Kulokhu iphutha likumklamo wokuqala njengoba ibhodi lingahlangabezani nezidingo zendawo yokusebenza kwalo.Amalungu ahlangene angaphumeleli ngesikhathi somhlangano ngenxa yokuphatha kabi kodwa kulokhu ubuso bokuhlanganyela bubonisa imigqa yokucindezeleka ekhiqizwe ngesikhathi sokunyakaza okuphindaphindiwe.
Umfanekiso 1: Imigqa yokucindezeleka lapha ibonisa ukuthi lokhu kuqhekeka ebhodini elihlangothini olulodwa kwabangelwa ukunyakaza okuphindaphindiwe ngesikhathi sokucubungula.
Umfanekiso wesi-2 ubonisa ukuqhekeka okuzungeze isisekelo se-fillet futhi uhlukanisiwe nephedi yethusi.Lokhu kungenzeka kakhulu ukuthi kuhlobene nokuthengiselana okuyisisekelo kwebhodi.Ukumanzisa phakathi kwe-solder ne-pad surface akuzange kwenzeke okuholela ekuhlulekeni kwamalunga.Ukuqhekeka kwamalunga ngokuvamile kuzokwenzeka ngenxa yokwanda okushisayo kwelunga futhi lokhu kuzohlobana nomklamo wangempela womkhiqizo.Akuvamile kakhulu ukwehluleka ukwenzeka namuhla ngenxa yesipiliyoni kanye nokuhlolwa kwangaphambili okwenziwa izinkampani eziningi ezihamba phambili zama-electronics.
Umfanekiso 2: Ukuntuleka kokumanzisa phakathi kwe-solder ne-pad surface kubangele lokhu kuqhekeka phansi kwe-fillet.
