Yintoni umatshini we-SMT?

Umatshini we-SMT (umatshini we-Surface-Mount Technology) sisixhobo esizisebenzelayo esisetyenziselwa ukufaka amacandelo e-elektroniki ngokuthe ngqo kwiibhodi zesekethe eziprintiweyo (PCBs). Aba matshini benza undoqo wemveliso nganye ye-SMT, kubandakanywa iiprinta zokuncamathisela ze-solder, oomatshini bokukhetha kunye nendawo, ii-oveni zokuphinda ziphume, kunye neenkqubo zokuhlola. Ngokudibeneyo, zenza isantya esiphezulu, ukuchaneka okuphezulu, kunye nendibano ye-elektroniki ezenzekelayo ngokupheleleyo kwiimveliso ezinjengee-smartphones, iimodyuli zeemoto, kunye neeyunithi zolawulo lwemizi-mveliso.

Ithetha ukuthini i-SMT?

SMTimele iITekhnoloji yoMphezulu weNtaba, indlela yokuvelisa apho amacandelo e-elektroniki-eyaziwa ngokubaSMDs(Izixhobo zokuNyuka ngaphezulu)-zixhonywe ngqo kumphezulu we-PCB endaweni yokufakwa kwimingxunya enjengezinto zemveli zokuphuma komngxuma.

Le ndlela iphelisa imfuno yokomba, inciphisa ubungakanani bebhodi kunye nobunzima, kwaye ivumela ukuxinana kwesekethe ephezulu kunye nokuveliswa ngokukhawuleza okuzenzekelayo.

Yintoni umatshini we-SMT?

AnUmtshini we SMTibhekisa kuso nasiphi na isixhobo esisetyenziswa kwinkqubo yokudityaniswa komphezulu wentaba. Kumgca opheleleyo wemveliso ye-SMT, oku kubandakanya:

• Isishicileli seNcamathelo ye-Solder-Ifaka intlama ye-solder kwi-PCB pads.

• Khetha kwaye ubeke umatshini- ibeka amacandelo e-SMD kwi-PCB encamathisiweyo.

• Hlaziya i-Oven- iyanyibilika i-solder paste ukuze unamathele ngokusisigxina amacandelo.

• Iinkqubo zokuHlola ze-AOI/SPI- khangela ukuchaneka kokubekwa kunye nomgangatho we-solder.

Ke ngoko, xa abantu bekhankanya "umatshini we-SMT," banokuthethaisixhobo esinye, okanyeyonke imveliso ye-SMTkuxhomekeke kumxholo.

Umatshini we-SMT vs uchola kwaye ubeke umatshini

La magama mabini adla ngokusetyenziswa ngokufanayo, kodwa awafani ncam.

Kufuphi:
👉 Wonke umatshini wokukhetha kunye nendawo uyinxalenye yeUmgca we-SMT, kodwa ayingawo wonke umatshini we-SMT ngumatshini wokukhetha kunye nendawo.

Iindidi zoomatshini be-SMT

Kumgca wendibano ye-SMT, oomatshini abahlukeneyo be-SMT benza iindima ezithile ngokuxhomekeke kwinqanaba lemveliso kunye nohlobo lwemveliso:

• Isishicileli sokuNcamalisa ngeSoda:Ifaka intlama ye-solder ngokuchanekileyo kwi-PCB pads.

• Khetha kwaye ubeke umatshini:Izikhundla ze-SMD zisebenzisa iingalo zerobhothi ezinesantya esiphezulu.
