Wave soldering ngakhale malata zimayambitsa ndi njira mankhwala

Makina opangira ma wave solderingngakhale malata ndi vuto wamba kupanga zinthu zamagetsi pulagi-mu yoweyula soldering, makamaka chifukwa cha solder yoweyula ngakhale malata chifukwa cha zifukwa zosiyanasiyana.Ngati mukufuna kusintha soldering yoweyula kuchepetsa ngakhale malata, m'pofunika kupeza zomwe zimayambitsa yoweyula soldering ngakhale malata.Pano kugawana zomwe zimayambitsa ndi kukonza malingaliro.

Kutentha kwa mafunde ndi malata.

1. Kutentha kwa Flux preheating ndikokwera kwambiri kapena kutsika kwambiri, nthawi zambiri kumakhala madigiri 100 ~ 110, kutentha kumatsika kwambiri, ntchito ya flux sikwera kwambiri.Preheat kwambiri, mu malata zitsulo flux wapita, komanso zosavuta ngakhale malata.
2. Palibe flux kapena flux sikokwanira kapena kusagwirizana, kugwedezeka kwa pamwamba kwa chitsulo chosungunuka cha malata sikumasulidwa, zomwe zimapangitsa kuti zikhale zosavuta kuziyika.
3. Yang'anani kutentha kwa ng'anjo ya malata, kulamulira pafupifupi madigiri 265, ndi bwino kugwiritsa ntchito thermometer kuti muyese kutentha kwa chiwombankhanga pamene chiwombankhanga chikugunda, chifukwa sensa ya kutentha ya zipangizo ikhoza kukhala pansi pa ng'anjo. kapena malo ena.Preheating kutentha sikokwanira kungachititse kuti zigawo zikuluzikulu sangathe kufika kutentha, ndi kuwotcherera ndondomeko chifukwa chigawo chimodzi mayamwidwe kutentha, chifukwa mu osauka kuukoka malata, ndi mapangidwe ngakhale malata.Pakhoza kukhala kutentha kochepa kwa ng'anjo ya malata, kapena liwiro la kuwotcherera ndilothamanga kwambiri.
4. Nthawi zonse macheke kuchita malata zikuchokera kusanthula, n'zotheka kuti mkuwa kapena zitsulo zili kuposa muyezo, chifukwa cha kuchepa kuyenda malata, mosavuta chifukwa ngakhale malata.
5. Yang'anani mbali ya njanji yowotchera mafunde, madigiri 7 ndiabwino kwambiri, osalala kwambiri osavuta kupachika malata.
6. IC ndi mzere wamapangidwe oyipa, kuphatikiza, mbali zinayi IC wandiweyani phazi katalikirana <0.4mm, osapendekeka pa bolodi.
7. PCB kutentha pakati lakuya mapindikidwe chifukwa ngakhale malata.
8. Chitsulo cha malata ndichokwera kwambiri, choyambiriracho chimadya malata ambiri, chokhuthala kwambiri, chiyenera kukhala chofanana.
9. Mapiritsi a board board sanapangidwe pakati pa dambo la solder, olumikizidwa pambuyo pa kusindikiza pa solder phala;kapena dera bolodi palokha lakonzedwa kuti solder damu / mlatho, koma yomalizidwa mankhwala mu gawo kapena zonse, ndiyenso zosavuta ngakhale malata.

Njira zopangira ma wave soldering ngakhale malata.

1. Flux sikokwanira kapena sikokwanira, onjezerani kuyenda.
2. United tin kuti mufulumizitse malo othamanga, malo okulitsa ngodya.
3. Osagwiritsa ntchito 1 yoweyula, ndi 2 mafunde a yoweyula limodzi, kudya malata kutalika sikuyenera kukhala 1/2, akhoza kungokhudza pansi pa bolodi mokwanira.Ngati muli ndi thireyi, ndiye kuti malata mu thireyi yotsekeredwa pamwamba kwambiri ndi abwino.
4. Kaya bolodi ndi olumala.
5. Ngati 2 wave single kugunda sikwabwino, ndi 1 wave punch, 2 wave imagunda pang'ono kukhudza mapiniwo, kuti mutha kukonza mawonekedwe a cholumikizira cholumikizira, chabwino.
