Muindasitiri yemagetsi, PCBA kugadzirisa kwesoftware zvinhu vanewave soldering muchinauye manual welding.Ndeupi musiyano uripo pakati peidzi nzira mbiri dzekushongedza, ndedzipi zvakanakira uye nekuipira?
I. Welding Hunhu uye Kubudirira Kwakanyanya Kuderera
1. Nekuda kwekushandiswa kweERSA, OK, HAKKO uye crack uye mamwe emhando yepamusoro akangwara emagetsi solder iron, welding quality yakagadziridzwa, asi kuchine zvimwe zvakaoma kudzora zvinhu.Somuenzaniso, solder uwandu uye welding wetting Angle kuzvidzora, nomoto kusachinja-chinja, zvinodiwa nerata mwero kuburikidza buri metallized.Kunyanya kana chikamu chinotungamira chiri chegoridhe-chakaputirwa, zvinodikanwa kubvisa goridhe uye tin lining kune chikamu chinoda tin-lead welding pamberi pewelding, chinova chinhu chinonetsa.
2. Manual welding kunewo zvinhu zvevanhu uye zvimwe zvikanganiso, zvakaoma kuzadzisa zvinodiwa zvemhando yepamusoro;Semuyenzaniso, nekuwedzera kwedunhu redunhu density uye nekuwedzera kwehupamhi hwebhodhi redunhu, iyo welding kupisa kugona kunowedzera, iyo soldering iron welding iri nyore kutungamira mukusakwana kupisa, kuumbwa kweiyo chaiyo welding kana kuburikidza negomba solder kukwira. kureba hakuenderane nezvinodiwa.Kana tembiricha yewelding yakawedzera zvakanyanya kana nguva yewelding yakareba, zviri nyore kukuvadza rakadhindwa redunhu bhodhi uye kuita kuti padhi iwire pasi.
3. Traditional soldering iron inoda kuti vanhu vakawanda vashandise point-to-point welding paPCBA.Selective wave soldering inoshandisa flux coating, yobva yatanga kupisa bhodhi redunhu/flux, uyezve kushandisa welding nozzle ye welding mode.Iyo indasitiri batch yekugadzira maitiro emutsetse wegungano inogamuchirwa.Welding nozzles ehukuru hwakasiyana anogona kusungirirwa mumabhechi nekudhonza welding.Kushanda kwewelding kunowanzo kukwira kakawanda kupfuura manual welding.
II.Wave Soldering Yemhando yepamusoro
1. wave soldering, welding, welding parameters ega ega solder joint inogona “kugadziridzwa”, iva neyakakwana process gadziriso nzvimbo kune imwe neimwe nzvimbo welding mamiriro, senge flux yekupfapfaidza huwandu, welding nguva, welding wave kureba uye wave kureba kunogadziriswa kusvika , hurema hunogona kudzikiswa zvakanyanya hungatozviita kuburikidza negomba zvidimbu zero defect for welding, The defect rate (DPM) ye selective wave soldering ndiyo yakaderera kana ichienzaniswa nemanual soldering, through-hole reflow soldering uye common wave soldering.
2. wave welding nekuda kwekushandisa programmable mobile tin tin cylinder uye akasiyana siyana anochinjika welding nozzle, saka mune welding process inogona kurongwa kudzivirira mamwe akamiswa screws uye ekusimbisa zvikamu zvePCB B side, kuti usabate yakakwirira tembiricha solder uye kukonzera kukuvara, hapana chikonzero chekugadzirisa iyo welding tray uye dzimwe nzira.
3. Kubva pakuenzanisa pakati pevheji welding uye manual welding, tinogona kuona kuti wave welding ine zvakawanda zvakanakira zvakadai sehutano hwakanaka, kushanda kwepamusoro, kushanduka kwakasimba, kuderera kwekuremara, kusvibiswa kuduku uye kusiyana-siyana kwezvikamu zvekugadzira.
