Momwe Mungasinthire Kuchuluka kwa Zokolola za Reflow Soldering

Momwe mungasinthire zokolola zazitsulo za CSP ndi zinthu zina?Kodi ubwino ndi kuipa kwa mitundu yowotcherera monga kutentha kwa mpweya ndi kuwotcherera kwa IR ndi chiyani?Kuphatikiza pakuwotchera mafunde, kodi pali njira ina yolumikizira zida za PTH?Momwe mungasankhire phala lapamwamba komanso kutentha kwa solder?

Kuwotcherera ndi njira yofunikira pakusonkhanitsa matabwa amagetsi.Ngati sichidziwika bwino, osati zolephera zambiri zokha zomwe zidzachitike, komanso moyo wamagulu a solder udzakhudzidwa mwachindunji.

Tekinoloje ya Reflow soldering si yachilendo pantchito yopanga zamagetsi.Zomwe zili pama board osiyanasiyana a PCBA omwe amagwiritsidwa ntchito mu mafoni athu amagulitsidwa ku board board kudzera munjira iyi.SMT reflow soldering imapangidwa ndi kusungunula zotsalira za solder pamwamba pa Solder, njira yowonjezera yomwe sichiwonjezera solder yowonjezera panthawi ya soldering.Kupyolera mu dera lotenthetsera mkati mwa zipangizo, mpweya kapena nayitrogeni umatenthedwa mpaka kutentha kokwanira ndikuwomberedwa ku bolodi lozungulira kumene zigawozo zayikidwa, kotero kuti zigawo ziwirizo The solder phala solder kumbali imasungunuka ndi kumangirizidwa motherboard.Ubwino wa njirayi ndikuti kutentha kumakhala kosavuta kuwongolera, oxidation imatha kupewedwa panthawi ya soldering, ndipo mtengo wopanga nawonso ndi wosavuta kuwongolera.

Reflow soldering yakhala njira yodziwika bwino ya SMT.Zambiri mwazinthu zomwe zili pama board athu a smartphone zimagulitsidwa ku board board kudzera munjira iyi.Zochita zolimbitsa thupi pansi pakuyenda kwa mpweya kuti mukwaniritse kuwotcherera kwa SMD;chifukwa chomwe chimatchedwa "reflow soldering" ndi chifukwa chakuti mpweya umayenda mu makina owotcherera kuti apange kutentha kwakukulu kuti akwaniritse cholinga chowotcherera.

Zida zopangira reflow ndi zida zofunika kwambiri pamisonkhano ya SMT.The solder olowa khalidwe la PCBA soldering zimadalira kwathunthu ntchito ya reflow soldering zida ndi kolowera kutentha pamapindikira.

Ukadaulo wa reflow soldering wakumana ndi mitundu yosiyanasiyana yachitukuko, monga kutentha kwa ma radiation a plate, kutentha kwa chubu cha quartz infrared chubu, kutentha kwa infrared air, kukakamiza kutentha kwa mpweya, kukakamizidwa kwa mpweya wotentha kuphatikiza chitetezo cha nayitrogeni, ndi zina zambiri.

Kuwongolera kwa zofunika pakuzizira kwa reflow soldering kumalimbikitsanso chitukuko cha malo ozizira a reflow soldering zida.Malo ozizirirapo mwachibadwa amazizira kutentha kwa chipinda, mpweya wokhazikika ku dongosolo lamadzi lopangidwa kuti ligwirizane ndi soldering yopanda kutsogolera.

Chifukwa cha kusintha kwa njira yopangira, zida za reflow soldering zili ndi zofunika kwambiri pakuwongolera kutentha, kufanana kwa kutentha m'dera la kutentha, ndi liwiro la kufalitsa.Kuchokera m'madera atatu oyambirira a kutentha, njira zowotcherera zosiyana monga madera asanu a kutentha, madera asanu ndi limodzi a kutentha, madera asanu ndi awiri a kutentha, madera asanu ndi atatu a kutentha, ndi magawo khumi a kutentha apangidwa.

Chifukwa cha miniaturization yosalekeza ya zinthu zamagetsi, zida za chip zawonekera, ndipo njira yowotcherera yachikhalidwe siyingakwaniritsenso zosowa.Choyamba, reflow soldering ndondomeko ntchito pa msonkhano wa hybrid madera Integrated.Zambiri mwazinthu zomwe zimasonkhanitsidwa ndikuwotcherera ndi chip capacitors, chip inductors, mount transistors ndi diode.Ndi chitukuko cha teknoloji yonse ya SMT kukhala yabwino kwambiri, mitundu yosiyanasiyana ya zida za chip (SMC) ndi zipangizo zokwera (SMD) zimawonekera, ndipo teknoloji ya reflow soldering process ndi zipangizo monga gawo la teknoloji yokwezera zapangidwanso moyenerera. ndipo kugwiritsa ntchito kwake kukuchulukirachulukira.Zakhala zikugwiritsidwa ntchito pafupifupi m'magawo onse amagetsi, ndipo ukadaulo wa reflow soldering wadutsanso magawo otsatirawa pakuwongolera zida.
