Kukho iimoto ezininzi zokuphinda zifakwe kwi-solder, yintoni imisebenzi yazo?Zingaphi iindawo zobushushu ezikhoyo, kwaye lithini iqondo lobushushu?

Yintoni i-reflow soldering?

I-Reflow soldering ibhekisela ekusebenziseni i-solder paste ukudibanisa enye okanye ngaphezulu kwezinto ze-elektroniki kwiipads zoqhagamshelwano, kunye nokunyibilikisa i-solder ngokufudumeza okulawulwayo ukufezekisa ukuxhamla ngokusisigxina.Iindlela ezahlukeneyo zokufudumeza ezinjengee-oveni zokufudumeza, izibane zokufudumeza nge-infrared, okanye imipu yobushushu ingasetyenziswa.yewelding.I-Reflow soldering yeyona ndlela ixhaphakileyo yokudibanisa izinto ze-elektroniki kwiibhodi zesekethe eziprintiweyo ngetekhnoloji yokunyuka komphezulu.Enye indlela kukudibanisa amacandelo e-elektroniki ngokufaka umngxuma womngxuma.

Umsebenzi weMotor we-reflow soldering?

Iqondo lokushisa elisebenzayo le-reflow soldering liphezulu kakhulu, kwaye umsebenzi oyintloko wemoto kukuqhuba ivili lomoya ukutshabalalisa ubushushu.

Zingaphi iindawo zobushushu ezinazo i-reflow soldering?Yintoni iqondo lobushushu?Yeyiphi indawo engundoqo?

I-Chengyuan reflow soldering yahlulwe yangamacandelo amane obushushu ngokomsebenzi wendawo yobushushu: indawo yokufudumeza, indawo yobushushu obungaguqukiyo, indawo yokuthambisa, kunye nendawo yokupholisa.

I-solder ye-reflow eqhelekileyo kwimarike ibandakanya i-solder ye-eight zone reflow soldering, i-solder ye-temperature ye-reflow soldering ye-temperature ye-temperature, i-solder ye-temperature ye-reflow soldering ye-12, i-solder ye-temperature ye-reflow ye-12, i-solder ye-temperature ye-reflow soldering ye-14, njl. Ezi zinokwenziwa ngokweemfuno zabathengi.Nangona kunjalo, i-soldering ye-reflow zone esibhozo kuphela yinto eqhelekileyo kwimarike yobuchwephesha.Ukuphinda kufakwe i-soldering kwiindawo ezisibhozo zobushushu, ukusetwa kweqondo lokushisa kwindawo nganye yobushushu kuhambelana ikakhulu ne-solder paste kunye nemveliso ekufuneka ithengiswa.Umsebenzi wezowuni nganye ubaluleke kakhulu.Ngokubanzi, indawo yokuqala neyesibini isetyenziswa njengezowuni zokufudumeza, kwaye eyesithathu neyesine ziindawo zokufudumeza.Indawo yeqondo lokushisa rhoqo, i-678 njengendawo yokuwelda (eyona nto ibalulekileyo yile mimandla mithathu), iindawo ezisi-8 zingasetyenziswa njengendawo encedisayo yendawo yokupholisa, kunye nendawo yokupholisa, ezi zingundoqo, kufuneka kuthiwe zimbalwa. iindawo zingundoqo , Umgangatho weMveliso kufuneka uphuculwe, yeyiphi indawo engundoqo!

1. Indawo yokufudumala

Indawo yokufudumeza ifudumeza ukuya kuma-degrees angama-175, kwaye ubude bumalunga ne-100S.Inokubonwa kule nto ukuba izinga lokufudumeza kwendawo yokufudumeza linokufumaneka (kuba le detector ithatha uvavanyo lwe-intanethi, ayizange ingene kwindawo yokufudumeza ixesha elide ukusuka kwi-0 ukuya kwi-46S. , ubude be-146-46 = 100S, kuba ubushushu bangaphakathi bungama-26 degrees 175–26=149 degrees shushu 149 degrees/100S=1.49 degrees/S)

2. Ummandla wobushushu rhoqo

Ubushushu obuphezulu kwindawo yobushushu obungaguqukiyo bumalunga nama-200 degrees, ubude bexesha yimizuzwana engama-80, kwaye umahluko phakathi kobushushu obuphezulu kunye nobushushu obuphantsi bungama-25 degrees.

3. Indawo yokuhanjiswa kwakhona

Iqondo lokushisa eliphezulu kwindawo yokubuyisela i-245 degrees, iqondo lokushisa eliphantsi kakhulu liyi-200 degrees, kwaye ixesha lokufikelela kwi-peak li malunga ne-35 / S;ukufudumeza kwindawo yokubuyisela kwakhona
Izinga: 45 degrees / 35S = 1.3 degrees / S Ngokutsho (indlela yokuseta ijika lobushushu ngokuchanekileyo), kunokubonwa ukuba ixesha le nqanaba lobushushu lifikelele kwixabiso eliphezulu lide kakhulu.Lonke ixesha lokubuyisela limalunga ne-60S

4. Indawo yokupholisa

Ixesha kwindawo yokupholisa malunga ne-100S, kwaye iqondo lokushisa lihla ukusuka kwi-245 degrees ukuya kwi-45 degrees.Isantya sokupholisa sithi: 245 degrees—45 degrees=200 degrees/100S=2 degrees/S
