Kuchulukitsa Msonkhano Ndi Wokwera, zinthu zamagetsi ndizochepa kwambiri kukula ndi kuwala kulemera, ndipo kuchuluka kwa kuchuluka kwake

Pambuyo posankha wamba, kuchuluka kwa zinthu zamagetsi kumachepetsedwa ndi 40% mpaka 60%, ndipo kulemera kumachepetsedwa ndi 60% mpaka 80%.

Kudalirika kwambiri komanso kugwedezeka kolimba. Mlingo wochepera wa msirikali wolowa.

Mawonekedwe abwino apamwamba. Kuchepetsa electromagnetic ndi rf kusokoneza.

Kulephera kukwaniritsa zolimbitsa thupi, sinthani bwino ntchito. Chepetsani mtengo wa 30% ~ 50%. Sungani deta, mphamvu, zida, manpower, nthawi, etc.

Chifukwa chiyani kugwiritsa ntchito maluso a Phiri la Phiri la Phiri (SMT)?

Zogulitsa zamagetsi zimafunafuna miniaturization, ndipo pulagi yopangidwa ndi mafuta omwe agwiritsidwa ntchito sangathenso kuchepetsedwa.

Ntchito yazogulitsa zamagetsi ndizokwanira, ndipo madera ophatikizidwa (iC

Zogulitsa zambiri, zopanga zokhazokha, fakitole mpaka mtengo wotsika, pangani zinthu zabwino kuti mukwaniritse zosowa za makasitomala ndikulimbitsa mpikisano wamsika

Kukula kwa zinthu zamagetsi, kukula kwa madera ophatikizika (a ICKC), kugwiritsa ntchito zambiri za semiconductor deta

Kusintha kwaukadaulo wamagetsi ndikofunikira, kuthamangitsa dziko lapansi

N 'chifukwa Chiyani Muyenera Kugwiritsa Ntchito Zoyera Pamalo a Phiri Lovala?

Pakupanga, madzi owononga pambuyo poyeretsa malonda amayambitsa kuipitsidwa kwamadzi, nthaka ndi nyama.

Kuphatikiza pa kuyeretsa madzi, gwiritsani ntchito ma soric okhala ndi chlorofluorocarbonas (CFC & HCFC) kuyeretsa kumayambitsa kuipitsidwa ndi kuwonongeka kwa mpweya ndi mlengalenga. Zotsalira za woyeretsa zidzayambitsa chimbudzi pa bolodi yamakina ndipo imakhudzanso mtundu wa malonda.

Kuchepetsa kukonza ndalama ndi ndalama zokonza makina.

Palibe kuyeretsa komwe kumatha kuchepetsa kuwonongeka komwe PCBA pakuyenda ndi kuyeretsa. Pali zinthu zina zomwe sizingatsukidwe.

Zotsalira za flux zimayendetsedwa ndipo zitha kugwiritsidwa ntchito malinga ndi zofunikira zopangira mawonekedwe kuti tipewe kuyang'ana zoyeretsa.

Kutsalira kopitilira muyeso kwakhala kokhazikika chifukwa cha ntchito yake yamagetsi kuti ilepheretse malonda kuti asadzutse magetsi, zomwe zimapangitsa zilizonse.

Kodi njira ya SMT Patch ndi iti ya SMT Patch kukonza?

Kuzindikira mu SMT Proces ndi njira yofunika kwambiri kuwonetsetsa kuti PCBA, njira yayikulu yodziwira imakhala ndi maluso a X. Munjira yodziwika ya SMT chigawenga chojambulidwa, kuyendera kwa Manja ndi Kuyendera kwa X-Ray ndi njira zitatu zomwe zimagwiritsidwa ntchito kwambiri pamsonkhano wapamtunda wa Party. Kuyesedwa pa intaneti kumatha kuyesedwa kochepa komanso kuyezetsa mwamphamvu.

Ukadaulo wapadziko lonse lapansi umakupatsani mawu oyamba kuzindikirika:

Choyamba, njira yamagetsi yowoneka.

Njirayi imathandizira pang'ono ndipo sizikufunika kukhazikitsa mapulogalamu oyesa, koma ndikuchedwa komanso osachedwa ndipo amafunikira kuyang'ana malo oyenerera. Chifukwa chakusowa kowoneka, sikugwiritsidwa ntchito ngati kuyerekeza kwakukulu kumatanthauza mzere wamakono wa SMT, ndipo ambiri amagwiritsidwa ntchito pokonzanso.

Chachiwiri, njira yowonetsera.

Ndi kuchepetsa kwa PCBA chip cog tofic kukula ndi kuwonjezeka kwa bolodi la madera osokoneza bongo, kuyenderana kumaso ndi kovuta, motero kudalirika kwa mphamvu, motero kugwiritsa ntchito chizindikiritso champhamvu kukukhala chofunikira kwambiri.

Gwiritsani ntchito zowunikira zowoneka bwino (AO1) ngati chida chochepetsa zolakwika.

Itha kugwiritsidwa ntchito kupeza ndi kusiya zolakwika kumayambiriro kwa chigamba cha chigamba kuti mukwaniritse njira yabwino. AOI amagwiritsa ntchito njira zapamwamba za kudyetsa, njira zatsopano, njira zokwanira komanso njira zovuta kusintha kuti mukwaniritse mitengo yayikulu yoyeserera.

Malo a AOL pa mzere wa SMT. Pali mitundu itatu ya AOI pa zida za AOI pa mzere wa SMT, woyamba ndi aoi zomwe zimayikidwa pazenera zowunikira kuti mudziwe kuti walonda uja, womwe umatchedwa Send-Screen Sealing AOL.

Lachiwiri ndi aoi yomwe imayikidwa pambuyo pa chigamba kuti muwone zolakwika zonyamula, zotchedwa post-chigamba aol.

Mtundu wachitatu wa AOI umayikidwa pambuyo pake kuti adziwe za chipangizo nthawi yomweyo, chotchedwa Post.
