Mavuto wamba ndi tact switch 6 × 6

Kusintha kwanzeru 6 × 6 SMTndi imodzi mwazinthu zogulitsa bwino kwambiri zamagetsi zamagetsi, chifukwa chakugwiritsa ntchito kwambiri ntchito, zakondedwa ndi makasitomala ambiri, ngakhale chinthucho chili chabwino bwanji ngati munthu wabwino, palibe changwiro, pali zolakwika zina ndi zina. zofooka.Pali zovuta zina ndi mankhwalawa, koma ndizabwino pakugwiritsa ntchito komanso mtundu wonse.Mavuto amatha kuwongolera ndi kupewedwa, monga kugwiritsa ntchito ndi kukonza.Kugwiritsa ntchito moyenera ndi kukonza bwino kungapangitse moyo wautali.Zotsatirazi ndizovuta kwambiri za TACT switch 6 × 6.

Kusintha kwanzeru 6 × 6 SMT mavuto wamba

Mtengo wotsutsa kwambiri: pakadali pano, makasitomala ambiri sadziwa bwino kukana kwa TACT switch 6 × 6.Nthawi zambiri, kukana kwa switch yathu kumayendetsedwa pansi pa 30m Ohms, kotero kukhudzana ndi moyo wa switch ndi zabwino kwambiri, koma masiwichi ena amakhala okana kwambiri pambuyo pa kutentha kwa ng'anjo ndi kuyesa kwa moyo.Kodi zotsatira za kukana kwakukulu pa TACT switch 6 × 6 ndi chiyani?Ngati kukana kuli kwakukulu, malo okhudzana ndi shrapnel ndi PIN PIN ya switch ndi yaying'ono.Malo ochezera ang'onoang'ono apangitsa kuti kusinthako kusalumikizana.Kusinthako kukapanda kulumikizidwa, kumakhala koyipa.

Choncho, tiyenera kusamala za kukana kwa lophimba, shrapnel ndi Pin kwa electroplating zofunika ndi mkulu, electroplating zabwino kukana mtengo adzakhala otsika.Sinthani muyeso wa moyo, pamwamba pa shrapnel idzavala, ngati plating ndi yopyapyala, kukana kuli kwakukulu, kusintha kuli koipa.

Awiri, kumamatira: kopitilira muyeso-woonda kwambiri TACT lophimba 6 × 6 amadziwika kuti woonda filimu lophimba, kusintha woonda kumafuna filimu woonda, kuti akwaniritse woonda kwenikweni.Koma zambiri kutentha filimu ntchito si bwino, pambuyo ng'anjo adzagwa chodabwitsa.Mawu athu akatswiri anati kumamatira, kwenikweni, filimu mamasukidwe akayendedwe ndi kuitanitsa PI filimu kulamulira bwino kwambiri pa izi, adhesion ake ndi 400 g, mogwirizana kwambiri ndi lophimba ntchito, mmene kuwala nthawi zambiri kugwa, ngati zolemetsa kwambiri kusintha malinga ndi zokhazikika. , opanga ambiri kuti apulumutse mtengo kuti asankhe filimu yotsika mtengo ya PI, kusinthana ndikosavuta kumamatira, Limbikitsani aliyense kuti afunse wopanga bwino asanagule.

Atatu, pambuyo ng'anjo sangathe akanikizire: lophimba wabwino, pambuyo backflow kuwotcherera zinachitikira sangathe akanikizire, osauka kwambiri.Makasitomala ambiri nawonso akuyankha vutoli, ndiye chifukwa chake ndi chiyani?Kusintha kwachigamba kumakhala kolumikizana ndi PCB, ndipo PIN imamatiridwa pa phala la solder.Ngati dzenje la ma mesh achitsulo ndi lalikulu pang'ono, phala la solder ndilosavuta kulowa mkati mwa chosinthira.Ngati pali thupi lachilendo mkati mwa chosinthira, zidzakhudza kuyenda kwake.Chofala kwambiri sichikuyenda.Chinthu chinanso ndi chakuti ntchito yosindikiza yosindikiza si yabwino, imalowa mkati, choncho vuto limabwera.

Chifukwa chake, akuti makasitomala akuyenera kulabadira vutoli popanga.

Chachinayi, chivindikiro chozimitsa: popanga, padzakhala kutayikira kwa chivindikiro ndikusintha kwamakasitomala.Kodi chivundikiro chabwino chosinthira chimachoka bwanji?Choyamba, tiyenera kumvetsetsa kapangidwe ka switch, chivundikiro cha switchcho chili kuseri kwa chivundikiro, izi ndi zaka miliyoni zakupanga kosalekeza.

Ngati mukuchidziwa bwino, mudzapeza kuti chivundikirocho chimakhazikitsidwa ndi mfundo zinayi zokhotakhota pamunsi.Malingana ngati nsonga zinayi zokhotakhota zili zotayirira kapena malo otsetsereka akuphwanyidwa kapena kupunduka pambuyo pa kutentha kwakukulu, chivundikirocho chidzagwa.Ingoganizirani mavuto awiri otsatirawa kuti muteteze chivindikiro, maziko ogwiritsira ntchito zipangizo zosagwira kutentha, mfundo ziwiri zothamangitsira ku riveting zokhazikika, chitani ntchito yabwino ya mavuto awiriwa, vutoli lathetsedwa bwino.

5. Kumverera kwa manja: Makasitomala ambiri akhala akuyankha, ndipo kumverera kwa manja kwa zitsanzo zomwe zimatumizidwa ndi ogulitsa ambiri ndizogwirizana kwambiri, koma pokhudzana ndi kupanga misala, kumverera kwa manja kumakhala kosiyana.M'malo mwake, vutoli ndilofala kwambiri, tonse tikudziwa kuti kumverera kosinthika ndi batani lamphamvu kumayendetsedwa ndi shrapnel.Nthawi zambiri timanena kuti shrapnel imagawidwa muzitsulo zamkuwa za phosphorous ndi zitsulo zosapanga dzimbiri.Pakali pano, opanga ambiri amasankha phosphorous mkuwa shrapnel kuti apulumutse mtengo.Phosphorus copper shrapnel ndi yotsika mtengo, yomwe ndichifukwa chake imagwiritsidwa ntchito kwambiri.Koma phosphor mkuwa shrapnel pambuyo kutentha ng'anjo kutulutsa kusintha, shrinkage ndi woopsa kwambiri, choncho kutsogolera osauka manja.

ntchito zosapanga dzimbiri shrapnel sadzakhala ndi vutoli, koma mtengo wa zosapanga dzimbiri shrapnel ndi mkulu, chifukwa opanga ambiri kusankha chiopsezo phosphorous mkuwa shrapnel, kotero mu kugula TACT lophimba 6 × 6 ayenera kufunsa mafunso omveka bwino. .

Six, atolankhani kuwala osati conductive: ogula ambiri, ntchito mankhwala nthawi zambiri anapeza kuti atolankhani batani atolankhani sayankha, kukhala zovuta kwambiri akanikizire, mankhwala ali ndi ntchito poyankha.Chifukwa masiwichi athu amawululidwa ndi mpweya, zinthu zambiri zomalizidwa sizimandidwa, ndipo zamagetsi zamagetsi zimafunikira kutentha.M'nyengo yamvula, shrapnel yosinthira imakhala yosavuta kuti ikhale ndi okosijeni, kukhudzana ndi makutidwe ndi okosijeni sikuli bwino monga kale, ndiko kuti, pali vuto losindikizira osati loyendetsa.

Tikachotsa chosinthira, timapeza kuti pali kadontho kakang'ono kakuda pa shrapnel, ndipo kadontho kakang'ono kakuda kameneka ndi zotsatira za okosijeni wa shrapnel.Chifukwa chake, tikulimbikitsidwa kuti zinthu zamagetsi zomwe sitigwiritsa ntchito nthawi wamba ziziyikidwa pamalo owuma, ndipo zida zamagetsi zolipiriratu ziyenera kukhala oxidized.
