Yintoni ikhetha kwaye ubeke umatshini?
Umatshini wokukhetha kunye nendawo yisixhobo esiphambili kunye neyinkimbinkimbi kwimveliso ye-SMT, esetyenziselwa ukunamathisela amacandelo ngesantya esiphezulu kunye nokuchaneka okuphezulu.Ngoku umatshini wokuchola kunye nendawo uphuhliswe ukusuka kumatshini we-SMT okhawulezayo osezantsi ukuya kwisantya esiphezulu se-optical centeringUmatshini we-SMT, kunye nemisebenzi emininzi, uqhagamshelwano oluguquguqukayo uphuhliso lwemodyuli.Kwimizila yemveliso ye-SMT, ixhotyiswe ngomatshini wokukhupha okanye umshicileli we-solder paste ukubeka ngokuchanekileyo amacandelo okunyusa umphezulu kwi-PCB pad ngokuhambisa intloko yentaba.Ngokwe-Colloquially, ngumatshini wokuncamathelisa izinto ze-elektroniki ze-pin chip kwibhodi yesekethe.
Khetha kwaye ubeke umgaqo wokusebenza komatshini
Umatshini wokukhetha kunye nendawo ozenzekelayo ulawulwa yikhompyutheni kwaye sisixhobo esizenzekelayo esichanekileyo esidibanisa i-optics, umbane kunye negesi.Ubukhulu becala iqulunqwe i-rack, i-PCB yokuhanjiswa kunye nombutho wokuthwala umthwalo, inkqubo yokuqhuba, i-positioning kunye ne-centering system, i-heading head, i-feeder, inkqubo yokuchonga i-optical, i-sensor kunye nenkqubo yokulawula ikhompyutha.Ngokufunxa, ukufuduswa, ukubeka kunye nokubeka imisebenzi, amacandelo e-SMD anokufakwa ngokukhawuleza.
Ngaba unakho ukukhetha kunye nokubeka i-solder yomatshini?
Umatshini wokukhetha kunye nendawo awukwazi ukuwelda.
I-NeDen ibonelela ngomoya oshushu wobuchwepheshareflow oven.Ihambisa amandla obushushu ngokusebenzisa intshukumo ye-laminar yomoya oshushu.I-heater kunye ne-fan zisetyenziselwa ukwenza umoya kwisithando somlilo uhlale uphakama kwaye ujikeleze.Iiwelds zifudunyezwa yirhasi eshushu eziko, ukuze kuqatshelwe ukuwelda.Isithando somlilo se-oven esitshisayo sineempawu zokufudumala okufanayo kunye nobushushu obuzinzile.Akukho lula ukulawula umahluko wobushushu phakathi kwePCB ephezulu nasezantsi kunye nethambeka lobushushu ecaleni kobude beziko, ngoko ke ayisetyenziswanga yodwa.Ukusukela ngeminyaka yee-1990, kunye nokwandiswa kwesicelo se-SMT kunye ne-miniaturization eyongezelelweyo yamacandelo, abavelisi bophuhliso lwezixhobo ukuphucula ukuhanjiswa kwesifudumezi, ukujikeleza kokuhamba komoya, kunye noluhlu lobushushu lokunyuka ukuya kwi-8, 10, ukuqhubela phambili ulawulo oluchanekileyo. yokusasazwa lobushushu eziko inxalenye nganye kulula ummiselo efanelekileyo ijiko lobushushu.Isithando somlilo esigcweleyo esishushu esinyanzelwa yi-convection reflow welding welding iye yaba sesona sixhobo sokuwelda se-SMT emva kokuphuculwa okuqhubekayo kunye nokugqibelela.
