Kodi Kusiyanitsa Pakati pa Kuwotcherera Kwa Laser ndi Kuwotcherera Kumbuyo Ndi Chiyani?

Chiyambi chareflow uvuni

Reflow uvuniamagwiritsa ❖ kuyanika flux, ndiye preheated circuit board / adamulowetsa flux, ndiyeno ntchito kuwotcherera nozzle mode kuwotcherera.Kuwotcherera kwachitsulo chochita kupanga kumafunika kugwiritsa ntchito kuwotcherera poyambira ndi nsonga pagawo lililonse la bolodi la dera, kotero kuti pakhale owonjezera ambiri.Makina opangira mafunde osankhidwandi mafakitale mtanda kupanga mode msonkhano, makulidwe osiyanasiyana kuwotcherera nozzle akhoza mtanda kuwotcherera, kawirikawiri kuwotcherera dzuwa akhoza bwino kangapo kuposa kuwotcherera pamanja (malingana ndi kamangidwe ka bolodi dera enieni).Chifukwa cha ntchito programmable mafoni yamphamvu yaing'ono malata ndi zosiyanasiyana kusinthasintha kuwotcherera nozzle, (malata yamphamvu mphamvu pafupifupi 11 makilogalamu), kotero kuwotcherera akhoza kukhazikitsidwa mwa pulogalamu kupewa bolodi dera pansi zina zomangira zokhazikika ndi kulimbikitsa ndi zina. mbali, kuti musagwirizane ndi kutentha kwakukulu kwa solder ndikuwononga kuwonongeka.Izi kuwotcherera mode, popanda kugwiritsa ntchito thireyi kuwotcherera mwambo ndi njira zina, ndi oyenera mitundu yambiri, yaing'ono mtanda kupanga mode.

Kuwotcherera reflow kuli ndi zabwino izi:

Kuchita bwino kwambiri pakuwotcherera, kumatha kuzindikira digirii yapamwamba yowotcherera yokha.

Kuwongolera kolondola kwa malo a jakisoni wa flux ndi kuchuluka kwa jakisoni, kutalika kwa nsonga ya microwave ndi malo owotcherera.

Chitetezo cha nayitrogeni pamwamba pa nsonga ya microwave;Kukhathamiritsa kwa magawo azinthu pagulu lililonse la solder.

Kubwezeretsa mwachangu ma nozzles amitundu yosiyanasiyana.

Single spot kuwotcherera ndi kudzera dzenje cholumikizira pini ndondomeko kuwotcherera luso kuphatikiza.

Malinga ndi zofunika akhoza kukhazikitsidwa solder olowa mawonekedwe "mafuta" "woonda" digiri.

Mukhoza kusankha mitundu yosiyanasiyana ya preheating (infuraredi, mpweya wotentha) ndi gawo lowonjezera la preheating pamwamba pa bolodi.

Kukonzekera kwapampu ya electromagnetic kwaulere.

Kusankhidwa kwa zipangizo zamapangidwe ndikoyenera kwathunthu kugwiritsa ntchito solder yopanda kutsogolera.

Mapangidwe a modular amachepetsa nthawi yokonza.

Chiyambi cha kuwotcherera laser

Gwero la kuwala kwa kuwotcherera kwa laser wobiriwira ndi laser light-emitting diode (LLED), yomwe imatha kuyang'ana ndendende cholumikizira chogulitsira kudzera mu makina owonera.Ubwino wa kuwotcherera kwa laser ndikuti imatha kuwongolera ndikuwongolera mphamvu zomwe zimafunikira pakuwotcherera.Ndi oyenera kusankha reflow kuwotcherera ndondomeko kapena ntchito malata waya cholumikizira.Pazigawo za SMD, phala la solder liyenera kugwiritsidwa ntchito poyamba ndiyeno welded.Njira yowotcherera imagawidwa m'magawo awiri: choyamba phala la solder limatenthedwa, ndipo cholumikizira cha solder chimatenthedwa.Pambuyo pake, phala la solder lomwe limagwiritsidwa ntchito powotcherera limasungunuka kwathunthu, ndipo solder imanyowetsedwa kwathunthu pa pedi kuti ipange weld. akhoza kukhala solder phala kapena malata waya, makamaka oyenera kuwotcherera yaing'ono danga solder malo kapena yaing'ono solder banga mphamvu ndi yaing'ono, kupulumutsa mphamvu.

Mawonekedwe a laser kuwotcherera

Multi-axis servo motor board board kuwongolera, kulondola kwamakhalidwe apamwamba.

Malo ang'onoang'ono a laser, m'kang'ono kakang'ono ka mapepala, zida zoyankhulirana zimakhala ndi ubwino wowotcherera.

Kuwotcherera osalumikizana, palibe kupsinjika kwamakina, chiopsezo chokhazikika.

Wuxi slag, kuchepetsa zinyalala flux, mtengo wotsika kupanga.

Zowotcherera zimakhala zolemera mumtundu.

Kusankha solder.

Ubwino wa kuwotcherera laser

Kwa ultra-fine electronic substrate, ma multilayer electronic components, "traditional technology" yalephera kugwiritsa ntchito, zomwe zinapangitsa kuti teknoloji ipite patsogolo.Kukonza magawo ang'onoang'ono omwe sali oyenerera njira yachitsulo yachitsulo kumatsirizidwa ndi kuwotcherera kwa laser.Non - kukhudzana kuwotcherera ndi mwayi waukulu wa kuwotcherera laser.Palibe chifukwa chokhudza gawo lapansi ndi zida zamagetsi konse, ndipo kupereka solder kokha ndi kuwala kwa laser sikubweretsa zolemetsa.Kutentha kogwira mtima ndi buluu laser mtengo ndi mwayi, womwe ungagwiritsidwe ntchito kuunikira malo opapatiza omwe mutu wa soldering sungathe kulowa komanso pamakona osiyanasiyana pamene palibe mtunda pakati pa zigawo zoyandikana ndi msonkhano wandiweyani.Mutu wachitsulo cha soldering uyenera kusinthidwa nthawi zonse, pamene zida zopangira laser kuwotcherera zimayenera kusinthidwa ndizochepa kwambiri ndipo mtengo wokonza ndi wotsika.
