Mayendedwe a Makina a Wave Soldering

1. Thirani madzi osayera ku bolodi

Wayikidwa mu zigawo zomalizidwa za bolodi la dera, zidzalowetsedwa mu jig, kuchokera pamakina omwe ali pakhomo la chipangizo chophatikizira kupita kumalo enaake amalingaliro ndi liwiro la kufalikira mumakina opangira ma wave soldering, ndiyeno ndi mosalekeza ntchito ya unyolo clamping clamping, njira kachipangizo kachipangizo, nozzle mmbuyo ndi mtsogolo pa chiyambi cha jig yunifolomu kutsitsi, kuti poyera PAD padziko bolodi dera, PAD pamwamba-dzenje ndi chigawo zikhomo. pamwamba wogawana TACHIMATA ndi woonda wosanjikiza wa flux.

2. Pre-kutentha PCB bolodi

M'dera preheating, PCB bolodi soldering mbali zimatenthedwa ndi kutentha konyowa, nthawi yomweyo, chifukwa cha kuchuluka kwa kutentha kwa gawo, kupewa kumizidwa mu solder yosungunuka mukakumana ndi mantha akulu otentha.Preheating siteji, kutentha kwa pamwamba PCB ayenera kukhala pakati pa 75 ~ 110 ℃ ndi koyenera.

1) Udindo wa preheating.

① zosungunulira mu flux ndi nthunzi, amene amachepetsa m'badwo wa gasi pamene soldering.

② flux mu rosin ndi wothandizila yogwira anayamba kuwola ndi yambitsa, akhoza kuchotsa zosindikizidwa bolodi ziyangoyango, chigawo nsonga ndi zikhomo pamwamba pa filimu okusayidi ndi zoipitsa zina, pamene akugwira ntchito kuteteza pamwamba zitsulo kuteteza kupezeka kwa mkulu. -kutenthanso kwa okosijeni.

③ kotero kuti PCB bolodi ndi zigawo zonse preheated, kupewa kuwotcherera pamene lakuthwa kukwera kutentha kwaiye matenthedwe nkhawa kuwonongeka PCB bolodi ndi zigawo zikuluzikulu.

2) yoweyula soldering makina mu njira wamba preheating

① Kutentha kwa mpweya

② Kutentha kwa heater ya infrared

③ Kutentha ndi kuphatikiza kwa mpweya wotentha ndi ma radiation

3. kuchita chipukuta misozi kutentha kwa soldering yoweyula.

Lowani kutentha chipukuta siteji, pambuyo chipukuta misozi ya bolodi PCB mu soldering yoweyula kuchepetsa mantha matenthedwe.

4. kupita ku bolodi lozungulira pamafunde oyamba

Mphuno yoyamba ndi spout yopapatiza ya "chipwirikiti" othamanga, machiritso ali ndi kulowa kwabwino kwa mthunzi wa zigawo zowotcherera.Nthawi yomweyo, chipwirikiti champhamvu chokwera cha jet chimapangitsa kuti mpweya wotuluka usamaphatikizidwe bwino, kumachepetsa kwambiri kutayikira kwa solder ndi zolakwika zodzaza moyima.

5. Yoweyula yachiwiri ya bolodi la dera

Mafunde achiwiri ndi "osalala" a solder akuyenda pang'onopang'ono, amatha kuchotsa solder ochulukirapo pa terminal, kuti zonse zowotchera pamwamba zinyowe bwino, ndipo zitha kukhala mafunde oyamba chifukwa chokoka nsonga ndi mlatho kuti akonze bwino.

6. bolodi lozungulira mu gawo lozizira

Dongosolo loziziritsa limapangitsa kutentha kwa PCB kutsika kwambiri kumatha kusintha kwambiri kupanga kopanda solder eutectic pamene kupanga thovu la mpweya ndi zovuta zovula thireyi.

Zhejiang NeoDen Technology Co., Ltd. yakhala ikupanga ndi kutumiza kunja zosiyanasiyana zazing'ono makina opangira ndi kukonzakuyambira 2010. Kutengera mwayi wathu olemera odziwa R&D, kupanga ophunzitsidwa bwino, NeoDen wapambana mbiri yabwino kwa makasitomala padziko lonse.
