Eqinisweni, i-SMT inezinhlobonhlobo zekhwalithi ezibonakala ngezikhathi ezithile, njenge-solder engenalutho, i-solder yamanga, ngisho ne-tin, izingxenye eziphukile, ezingekho, i-offset, njll., izinkinga zekhwalithi ezahlukene zinezizathu ezifanayo, kunezizathu ezahlukene, namuhla sizokhuluma. kuwe mayelana ne-SMT solder engenalutho yiziphi izizathu futhi uthuthukise izinyathelo zokuphikisa.
I-soldering engenalutho isho ukuthi izakhi, ikakhulukazi izingxenye ezinamaphinikhodi azikho i-tin ekhuphukayo, ebizwa ngokuthi i-solder engenalutho, i-solder engenalutho inezizathu ezilandelayo eziyi-8:
1.Ukuvulwa kwe-stencil okungalungile
Ngenxa yokuthi isikhala sephini siminyene kakhulu, ngakho-ke imbobo incane kakhulu, incane kakhulu, uma ukunemba kokuvula imbobo kukubi kuzoholela ekunamathiseleni akukwazi ukuvuza noma ukuvuza kuphrintiwe okuncane kakhulu, okuholela ekutheni iphedi alinameki, i-soldering ngemuva kokuvela i-solder engenalutho.
Isixazululo: i-stencil evulekile enembile
2. Umsebenzi wokunamathisela i-solder ubuthakathaka
I-Solder paste ngokwayo umsebenzi wenkinga ubuthakathaka, ukunamathisela kwe-solder akulula ukuncibilika okushisayo
Isixazululo: Faka esikhundleni se-solder esebenzayo
3. Ukucindezela kwe-scraper kuphezulu
I-Solder inamathisela ukuvuza i-coating ephrintiwe kuma-pcb pads, isidingo sokukhuhla emuva naphambili futhi, uma ingcindezi ye-scraper nesivinini, ukuvuza kwe-solder paste kuyoba kuncane kakhulu, okuholela ku-solder engenalutho.
Isixazululo: lungisa ingcindezi nesivinini se-scraper
4. Ingxenye yezikhonkwane ze-warp deformation
Ezinye izikhonkwane ziyasonteka noma zikhubazekile ekuhambeni, okuholela ekutheni unamathisele oshisayo oncibilikayo we-solder awukwazi ukukhuphuka uthayela, okuholela ekuthuthweni okungenalutho.
Isixazululo: hlola ngaphambi kokusetshenziswa bese usebenzisa
5. Icwecwe lethusi le-pcb elingcolile noma eline-oxidized
Icwecwe le-pcb lethusi lingcolile noma line-oxidised, okuholela ekukhaseni kahle kwephini, okuholela ekuhlanganisweni okungenalutho.
Izinyathelo zokulwa: i-pcb kufanele isetshenziswe ngokushesha ngangokunokwenzeka ngemuva kokuvulwa, futhi kufanele ibhakwe futhi ihlolwe ngaphambi kokusetshenziswa.
6. Reflow soldering umshini indawo yokushisa yangaphambi kokushisa ishisa ngokushesha kakhulu
I-Reflow soldering preheating zone ishisa ngokushesha kakhulu, okuholela ekunamathiseleni kwe-solder okuncibilikisiwe endaweni yokushisisa kanye ne-soldering.
Izinyathelo zokuphikisa isixazululo: setha ijika lokushisa elifanelekile lesithando somlilo
7. Umshini we-SMTukubekwa kwengxenye offset
Ngenxa yokuthi isikhala sephini siminyene kakhulu, ukunemba komshini othile akukwazi ukufinyelela, okuholela ekumisweni kokubeka, hhayi ukubekwa kwephini kuphedi ekhethiwe.
Izinyathelo zokulwa nesixazululo: thenga isikhweli esinembayo esiphezulu
8. I-solder unama ukuphrinta i-offset
Umshini wokunyathelisa we-solder unamathisele umshini wokunyathelisa we-offset, kungase kube isizathu se-stencil, futhi kungase kube ipuleti lokunamathisela elixekethile
Isixazululo: lungisa umshini wokuphrinta we-solder unama, lungisa ithrekhi yethebula lethebula ukuze ulungiswe.
Ukucaciswa kweI-NeoDen reflow oven IN6
Ukulawula okuhlakaniphile okunenzwa yokushisa ezwelayo ephezulu, izinga lokushisa lingakwazi ukuzinza ngaphakathi kuka + 0.2 ℃.
Ipuleti lokushisisa ingxubevange ye-aluminium esebenza kahle kakhulu esikhundleni sepayipi lokushisisa, kokubili ukonga amandla nokusebenza kahle kakhulu, kanye nomehluko wokushisa oguquguqukayo ungaphansi kuka-2℃.
Amafayela amaningana asebenzayo angagcinwa, ashintshe ngokukhululekile phakathi kwe-Celsius ne-Fahrenheit, aguquguquke futhi aqondeke kalula.
I-Japan NSK motor motor bearings kanye ne-Swiss heat heat wire, ihlala isikhathi eside futhi izinzile.
Idizayini engaphezulu kwetafula yomkhiqizo ikwenza ube yisixazululo esiphelele semigqa yokukhiqiza enezidingo ezihlukahlukene.Idizayinelwe nge-automation yangaphakathi esiza opharetha ukuthi bahlinzeke nge-solder ehlelekile.
Idizayini isebenzisa ipuleti lokushisisa ingxubevange ye-aluminium enyusa ukusebenza kahle kwamandla kwesistimu.Isistimu yokuhlunga intuthu yangaphakathi ithuthukisa ukusebenza komkhiqizo futhi inciphisa okukhiphayo okuyingozi, nayo.
Amafayela asebenzayo ayabekeka kuhhavini, futhi womabili amafomethi e-Celsius ne-Fahrenheit ayatholakala kubasebenzisi.Ihhavini isebenzisa umthombo wamandla we-110/220V AC futhi inesisindo esiphelele (G1) esingu-57kg.
