I-SMT kanye Nobuhle Bayo Emabhodini Omjikelezo

Yini i-SMT? Kungani i-SMT iye yamukelwa ngokuvamile, yaqashelwa futhi yakhuthazwa imboni yezogesi uma isiphumile? Namuhla u-Capel uzokukhiphela yona ngamunye ngamunye.

I-Surface Mount Technology:

Kuwukusetha ngaphambili i-powder efana ne-alloy (i-solder paste kafushane) kuwo wonke amaphedi azoxhunywa ku-PCB ngokuphrinta, ukumbozwa ngamabala, noma ukufutha, bese kuba izingxenye zokukhweza ngaphezulu (SMC/SMD) ) indawo ecacisiwe ebusweni be-PCB, bese uqedela ukuncibilika kanye nokuhlangana kwe-solder unamathisele kuwo wonke amajoyinti afaka i-solder esithandweni esikhethekile esishiwo ukuqedela yonke inqubo yokuxhuma ye-PCBA. Ukuqoqwa kwalobu buchwepheshe kubizwa nge-surface mount technology, igama lesiNgisi lithi “Surface Mount Technology, SMT ngamafuphi.

Ngenxa yokuthi imikhiqizo ye-elekthronikhi eqoqwe yi-SMT inochungechunge lwezinzuzo eziphelele njengosayizi omncane, ikhwalithi enhle, ukwethembeka okuphezulu, inqubo yokukhiqiza okuzenzakalelayo, ukuphuma okuphezulu, ukucaciswa komkhiqizo okungaguquki, nokusebenza kwezindleko ezinhle kakhulu, iye yaqashelwa kabanzi futhi yathandwa yi-electronics. imboni. Ngakho-ke, ngemuva kokuthi umkhiqizo wamukele i-SMT, yiziphi izinzuzo ezingatholwa umkhiqizo?

Izinzuzo zokusebenzisa i-SMT emikhiqizweni:

1. Ukuminyana okuphezulu komhlangano: Ngokuvamile, uma kuqhathaniswa nenqubo ye-THT, ukusetshenziswa kwe-SMT kunganciphisa umthamo wemikhiqizo kagesi ngo-60% futhi kunciphise isisindo ngo-75%;

2. Ukuthembeka okuphezulu: Kokubili izinga lokuphasa lokuqala lamajoyinti e-solder ekukhiqizeni umkhiqizo kanye nesikhathi esimaphakathi phakathi kokuhluleka (MTBF) kwemikhiqizo kwenziwe ngcono kakhulu;

3. Izici ezinhle ze-high-frequency: Njengoba i-SMC/SMD ngokuvamile ingenayo imikhondo noma imikhondo emifushane, ithonya le-parasitic inductance kanye ne-capacitance liyancishiswa, izici ze-high-frequency zesifunda ziyathuthukiswa, futhi isikhathi sokudlulisa isignali sifinyeziwe;

4. Izindleko eziphansi: Indawo ye-PCB esetshenziselwa i-SMT ingu-1/12 kuphela wendawo ye-THT enomsebenzi ofanayo. I-SMT isebenzisa i-PCB ukunciphisa ukubhola okuningi, okunciphisa izindleko zokukhiqiza i-PCB; ukuncishiswa kwevolumu kanye nekhwalithi kusindisa kakhulu izindleko zokupakishwa nokuthutha umkhiqizo; izindleko zizonke zomkhiqizo ziyancipha kakhulu, futhi ukuncintisana okuphelele komkhiqizo emakethe kuyathuthukiswa. amandla;

5. Yenza lula ukukhiqizwa okuzenzakalelayo: Ekukhiqizeni ngobuningi, kungenziwa ngokuzenzakalela, ngokukhipha okuphezulu, umthamo omkhulu, ikhwalithi ezinzile, ukwethembeka okuphezulu, kanye nezindleko zokukhiqiza eziphansi ezihlanganisiwe.

I-Shenzhen Capel Technology Co., Ltd. isungule imboni yokukhiqiza ibhodi lesifunda kusukela ngo-2009 futhi ihlinzeka ngezinsizakalo zomhlangano we-SMT PCB. Eminyakeni eyi-15 edlule, iqoqe ulwazi olucebile, ithimba lochwepheshe, imishini ethuthukisiwe nemishini, kanye namakhono okukhiqiza athuthukile. Ixazulule izinkinga ezihlukahlukene zenkinga yephrojekthi yamakhasimende.
