Uninzi lwezixhobo ze-elektroniki ezenziwe ngobuninzi namhlanje zenziwa kusetyenziswa iteknoloji yokunyuka komhlaba okanye i-SMT, njengoko ibizwa njalo. Ngaphandle kwesizathu! Ukongeza ekunikezeleni ezinye izibonelelo, i-SMT PCB unokuhamba indlela ende ekukhawuleziseni amaxesha emveliso yePCB.

Itekhnoloji yokunyuka komhlaba

Isiseko seNtaba yeTekhnoloji yeNtloko (i-SMT) Umba osisiseko wokudibanisa umngxuma uyaqhubeka nokubonelela ngophuculo olubalulekileyo. Ngokusebenzisa i-SMT, i-PCB akufuneki ukuba igrunjwe kuyo. Endaweni yoko, into abayenzayo basebenzisa i-solder paste. Ukongeza kokongeza isantya esikhulu, oku kuyenza lula inkqubo. Ngelixa izinto ezinyukayo ze-SMT zingenakuba namandla okonyuka ngomngxunya, zinikezela ngezinye izibonelelo ezininzi zokucombulula le ngxaki.

Itekhnoloji yokuphakama komphezulu ihamba ngenkqubo yamanyathelo ama-5 ngolu hlobo lulandelayo: 1. Imveliso ye-PCB-Eli linqanaba 2 apho i-PCB inyusa ukuvelisa amalungu. I-solder ifakwe kwi-pad, ivumela icandelo ukuba lizinze kwibhodi yesekethe 3. Ngoncedo lomatshini, izinto zibekwa kumalungu afanelekileyo e-solder. Bhaka i-PCB ukuze wenze i-solder ibe lukhuni 5. Jonga izinto ezigqityiweyo

Umahluko phakathi kwe-SMT kunye ne-hole-hole uquka:

Ingxaki ebanzi yendawo ekufakweni kwemingxunya isonjululwa ngokusetyenziswa kwetekhnoloji yaphezulu. I-SMT ikwabonelela ngokuguquguquka koyilo kuba inika abayili be-PCB inkululeko yokwenza iisekethe ezinikezelweyo. Ubungakanani bezinto ezincinci zithetha ukuba izinto ezingaphezulu zinokulingana kwibhodi enye kwaye kufuneka iibhodi ezimbalwa.

Izixhobo kufakelo lwe-SMT azikhokeleli. Mfutshane ubude bendawo yokukhwela kumphezulu womhlaba, kokukhona kulibazisa ukulibaziseka kunye nengxolo yokupakisha esezantsi.

Ukuxinana kwamacandelo kwindawo nganye yeyunithi kuphezulu kuba kuvumela ukuba izinto zibekwe kumacala omabini.

Ilungele ukuveliswa kwemveliso, ngaloo ndlela kuncitshiswa iindleko.

Ukunciphisa ubungakanani kwandisa isantya sesekethe. Esi sesona sizathu siphambili sabona bavelisi bakhetha le ndlela.

Uxinzelelo lobuso be-solder etyhidiweyo lutsala ulungelelwaniso kunye nephedi. Oku kulungisa ngokuzenzekelayo naziphi na iimpazamo ezincinci ezinokuthi zenzeke ekubekweni kwezinto.

I-SMT ibonakalise ukuba izinzile ngakumbi xa kukho ukungcangcazela okanye ukungcangcazela okuphezulu.

Iinxalenye ze-SMT zihlala zibiza imali engaphantsi kunezahlulo ezifanayo.

Ngokubalulekileyo, i-SMT inokuwanciphisa kakhulu amaxesha emveliso kuba akukho kubhola kuyafuneka. Ukongeza, izinto ze-SMT zinokubekwa kwinqanaba lamawaka ngeyure, xa kuthelekiswa nangaphantsi kwewaka ngokufakwa kwemingxunya. Oku, kukhokelela ekubeni iimveliso zenziwe ngesantya esifunwayo, esiye sinciphise ixesha lokuthengisa. Ukuba ucinga ukukhawulezisa amaxesha emveliso ye-PCB, i-SMT yeyona mpendulo icacileyo. Ngokusetyenziswa koyilo kunye noKwenziwa (DFM) izixhobo zesoftware, isidingo sokuphinda sisebenze kunye nokuyilwa ngokutsha kweesekethe ezintsonkothileyo sincitshisiwe, sandisa isantya kunye nokubanakho koyilo oluntsonkothileyo.

Konke oku akuthethi ukuba i-SMT ayinazintsilelo zendalo. I-SMT inokungathembeki xa isetyenziswa njengekuphela kwendlela yokuncamathisela iindawo ezijamelene noxinzelelo olubonakalayo. Izinto ezivelisa ubushushu obukhulu okanye ukumelana nemithwalo ephezulu yombane azinakufakwa zisebenzisa i-SMT. Kungenxa yokuba i-solder iyanyibilika kubushushu obuphezulu. Ke ngoko, ukufakwa emngxunyeni kunokuqhubeka nokusetyenziswa kwiimeko apho oomatshini abakhethekileyo, ombane kunye nezinto ezishushu zenza ukuba i-SMT ingasebenzi. Ukongeza, i-SMT ayikulungelanga ukwenza iprototyping kuba izinto ezinokufuna ukongezwa okanye ukutshintshwa ngexesha lesigaba seprototyping, kwaye iibhodi zamanani aphezulu zinokuba nzima ukuxhasa.

Sebenzisa i-SMT

Ngoncedo oluqinileyo olunikezelwa yi-SMT, kuyamangalisa ukuba babe luyilo lwanamhlanje olubalaseleyo kunye nomgangatho wokuvelisa. Ngokusisiseko inokusetyenziswa kuyo nayiphi na imeko apho kufuneka ukuthembeka okuphezulu kunye nomthamo ophezulu wePCBS.
