Iingcebiso malunga nokusetyenziswa ngokuchanekileyo komatshini wokuthambisa we-reflow

Hlaziya i-oveniamanyathelo okusebenza

1. Khangela ukuba kukho i-debris ngaphakathi kwesixhobo, yenza umsebenzi omhle wokucoca, ukuqinisekisa ukhuseleko, vula umatshini, ukhethe inkqubo yokuvelisa ukuvula izicwangciso zeqondo lokushisa.

2. Ububanzi besikhokelo se-oven reflow ukuba bulungelelaniswe ngokobubanzi bePCB, vula umoya wezothutho, uthutho lwebhanti yemesh, fan yokupholisa.

3. Reflow soldering machineulawulo lobushushu inelothe eliphezulu (245 ± 5) ℃, iimveliso ilothe inkonkxa ulawulo lobushushu kwi (255 ± 5) ℃, ubushushu preheating: 80 ℃ ~ 110 ℃.Ngokweeparamitha ezinikezwe yinkqubo yokuvelisa i-welding ngokungqongqo kwaye ngokungqongqo lawula umatshini wokubuyisela iiparamitha zekhompyuter, bhala iiparamitha zomatshini wokubuyisela ngexesha yonke imihla.

4. ukuze ngokulandelelana uvule ubushushu iswitshi, ukuba iqondo lobushushu iseti xa ungaqala phezu, PCB, ibhodi, phezu kwebhodi ingqalelo ulwalathiso.Qinisekisa ukuba umgama phakathi kweebhodi ezi-2 ezilandelelanayo zebhanti yokuhambisa ayikho ngaphantsi kwe-10mm.

5. Ukulungelelaniswa kwebhanti yokuhambisa i-reflow ye-soldering ye-conveyor kwisithuba esifanelekileyo, ububanzi bebhanti yokuhambisa kunye ne-flatness kunye nebhodi yomgca, khangela izinto eziza kucutshungulwa inombolo yebhetshi kunye neemfuno zobugcisa ezinxulumene nazo.

6. Umatshini wokuphinda ube mde kakhulu, ubushushu buphezulu kakhulu obubangelwa yinto yobhedu lweplatinum;i-solder joints kufuneka igudiswe kwaye ikhanye, ibhodi yesiphaluka kufuneka ibe yizo zonke iipads kwi-tin;imigca ethengiswe kakubi kufuneka iphinde igqitywe, ukuphinda-phinda okwesibini kuya kwenziwa emva kokupholisa

7. ukunxiba iiglavu ukuze uthabathe i-solder PCB, uthinte kuphela umda we-PCB, isampuli isampuli ezili-10 ngeyure, khangela imeko embi, kwaye urekhode idatha.Ngethuba lenkqubo yokuvelisa, ukuba ufumanisa ukuba iiparitha azikwazi ukuhlangabezana neemfuno zokuvelisa, awukwazi ukulungelelanisa iiparitha ngokwakho, kufuneka ukhawuleze uxelele uchwepheshe ukuba ajongane nayo.

8. Linganisa iqondo lobushushu: iplagi i-sensor iguqukele kwisokethi yokufumana umvavanyi, vula iswitshi yamandla evavanyayo, beka umvavanyi ngaphakathi kwi-solder reflow kunye nebhodi endala ye-PCB phezulu kwi-solder yokubuyisela, susa umhloli ngekhompyutha ukuze ufunde. idatha yobushushu erekhodiweyo ngexesha lenkqubo yokuthengisa i-reflow, oko kukuthi, idatha yoqobo ye-reflow soldering ijika lobushushu.

9. Uya kuba uthengise ibhodi ngokwenombolo enye, igama, njl njl.Ukuze kuthintelwe ukuxuba izinto ukuvelisa ezimbi.

Reflow soldering operation ye-oven

1. Musa ukuchukumisa ibhanti ye-mesh ngexesha lokusebenza kwaye ungavumeli amabala amanzi okanye ioli ukuba awele kwisithando somlilo ukukhusela ukutshisa.

2. Imisebenzi ye-welding kufuneka iqinisekise ukungena komoya, ukuthintela ukungcoliseka komoya, abaqhubi kufuneka banxibe iimpahla ezilungileyo zokusebenza, banxibe imaski elungileyo.

3. Rhoqo uvavanye ukufudumeza ngocingo, ukuthintela ukuvuza kokuguga.
