Embonini ye-elekthronikhi, ukucutshungulwa kwe-PCBA yezinto zesoftwareumshini we-wave solderingkanye ne-welding manual.Uyini umehluko phakathi kwalezi zindlela ezimbili zokushisela, yiziphi izinzuzo kanye nokubi?
I. Ikhwalithi Nokusebenza Kwe-Welding Kuphansi Kakhulu
1. Ngenxa yokusetshenziswa kwe-ERSA, OK, HAKKO kanye ne-crack kanye nezinye izinsimbi ezihlakaniphile zokufaka ugesi ezihlakaniphile, izinga lokushisela liye lathuthukiswa, kodwa kusenzima ukulawula izici.Ngokwesibonelo, inani solder kanye Welding wetting Ukulawula Angle, Welding ukungaguquguquki, izidingo izinga tin ngokusebenzisa imbobo metallized.Ikakhulukazi uma ingxenye yomthofu ifakwe ngegolide, kuyadingeka ukususa igolide nethayela engxenyeni edinga i-tin-lead welding ngaphambi kokushisela, okuyinto enzima kakhulu.
2. Welding Manual futhi kukhona izici zomuntu kanye nezinye amaphutha, kunzima ukuhlangabezana nezidingo izinga eliphezulu;Isibonelo, ngokwanda komthamo webhodi lesifunda kanye nokwanda kobukhulu bebhodi lesifunda, umthamo wokushisa we-welding ukhuphuka, i-soldering iron welding kulula ukuholela ekushiseni okunganele, ukwakheka kwe-welding ebonakalayo noma ngokukhuphuka kwe-solder yembobo. ukuphakama akuhlangabezani nezidingo.Uma izinga lokushisa le-welding likhuphuka ngokweqile noma isikhathi se-welding siqhubeka isikhathi eside, kulula ukulimaza ibhodi lesifunda eliphrintiwe futhi libangele ukuba i-pad iwele.
3. Insimbi yokudambisa yendabuko idinga abantu abaningi ukuthi basebenzise i-point-to-point welding ku-PCBA.I-wave soldering ekhethiwe isebenzisa i-flux coating, bese ishisa kuqala ibhodi lesekhethi/i-flux, bese isebenzisa umbhobho wokushisela ngemodi yokushisela.Imodi yokukhiqiza inqwaba yezimboni yomugqa wokuhlanganisa iyamukelwa.Imilomo yokushisela yosayizi abahlukene ingashiswa ngamaqoqo ngokuhudula i-welding.Ukusebenza kahle kwe-welding kuvame ukuphindwe kaningi kune-welding manual.
II.I-Wave Soldering Yekhwalithi Ephezulu
1. i-wave soldering, i-welding, imingcele yokushisela yelunga ngalinye le-solder "ingalungiswa", ibe nesikhala esanele sokulungisa inqubo endaweni ngayinye yezimo zokushisela, njengokugeleza komthamo wokufafaza, isikhathi sokushisela, ukuphakama kwegagasi lokushisela nokuphakama kwegagasi okuguquguqukayo ukuze kube ngcono kakhulu. , ukukhubazeka kungancishiswa kakhulu kungakwenza ngisho nangezingxenye zembobo ukungasebenzi kahle kwe-zero ekushiseleni, Izinga lokukhubazeka (DPM) lokukhetha amagagasi e-wave soldering liphansi kakhulu uma liqhathaniswa ne-soldering eyenziwa ngesandla, i- through-hole reflow soldering kanye ne-wave soldering evamile.
2. i-wave welding ngenxa yokusetshenziswa kwesilinda esincane sethayela esihlelekayo kanye nezinhlobonhlobo ze-nozzle yokushisela eguquguqukayo, ngakho-ke enqubweni yokushisela ingahlelwa ukugwema ezinye izikulufu ezingaguquki kanye nezingxenye zokuqinisa ze-PCB B side, ukuze ungaxhumani izinga lokushisa eliphezulu le-solder futhi libangele umonakalo, asikho isidingo sokwenza ngokwezifiso i-welding tray nezinye izindlela.
3. Kusukela ekuqhathaniseni phakathi kwe-wave welding kanye ne-manual welding, singabona ukuthi i-wave welding inezinzuzo eziningi ezifana nekhwalithi ye-welding enhle, ukusebenza kahle okuphezulu, ukuguquguquka okuqinile, izinga eliphansi lesici, ukungcola okuncane kanye nokuhlukahluka kwezingxenye zokushisela.
