Popeza ma chip inductors ali ndi zinthu monga miniaturization, mtundu wapamwamba kwambiri, kusungirako mphamvu zambiri, ndi DCR yotsika kwambiri, pang'onopang'ono yalowa m'malo mwa ma plug-in inductors m'magawo ambiri.Pamene makampani apakompyuta akulowa mu nthawi ya miniaturization ndi flattening, ma chip inductors amagwiritsidwa ntchito kwambiri pamagwiritsidwe osiyanasiyana.Nthawi yomweyo,chip inductorszing'onozing'ono ndi zazing'ono, zomwe zimabweretsanso zovuta pakuwotcherera chip inductor.
Njira zodzitetezera pakuwotcherera preheating
Chifukwa cha kukula kwake kochepa komanso kochepa, pali kusiyana kwakukulu pakati pa soldering ya chip inductors ndi plug-in inductors.Zomwe ziyenera kutsatiridwa ndi ma solder chip inductors?
1. Musanayambe kuwotcherera chip inductor, m'pofunika kumvetsera kutenthedwa kuti mupewe kutentha kwa kutentha panthawi yowotcherera.
2. Kutentha kwa preheating kumafuna kukwera pang'onopang'ono, makamaka 2 ℃/sec, ndipo sikuyenera kupitirira 4 ℃/sec.
3. Onani kusiyana kwa kutentha pakati pa kutentha kwa kuwotcherera ndi kutentha kwa pamwamba Nthawi zambiri, kusiyana kwa kutentha pakati pa 80 ℃ ndi 120 ℃ ndikwachilendo.
4. Pa kuwotcherera, ziyenera kudziwika kuti kutentha kwa kutentha kudzawonjezeka ndi kuwonjezeka kwa kukula kwa chip inductor kapena kutentha.
Solderability
Kumizidwa kwa nkhope yomaliza ya chip inductor mu ng'anjo ya malata pa 235 ± 5 ℃ kwa 2 ± 1 masekondi kumatha kupeza zotsatira zabwino zogulitsira.
Kugwiritsa ntchito flux pa kuwotcherera
Kusankha cholumikizira choyenera kumathandizira kuteteza pamwamba pa inductor.Taonani mfundo zotsatirazi.
1.Zindikirani kuti sipayenera kukhala ma asidi amphamvu mu flux pamene kuwotcherera inductor wa chigamba.Nthawi zambiri amagwiritsidwa ntchito kuyambitsa mild rosin flux.
2.Ngati madzi osungunuka madzi amasankhidwa, chidwi chapadera chiyenera kuperekedwa ku ukhondo wa gawo lapansi musanayambe kuwotcherera.
3.Pamalingaliro owonetsetsa kuwotcherera kwabwino, samalani kugwiritsa ntchito kusinthasintha pang'ono momwe mungathere.
Kusamala kwa kuwotcherera ndondomeko
1.Gwiritsani ntchito reflow soldering momwe mungathere kuti mupewe soldering pamanja.
2.Zindikirani kuti kugwedeza kwa mafunde sikuvomerezeka kwa ma chip inductors akulu kuposa kukula kwa 1812.Chifukwa pamene chip inductor kumizidwa mu mafunde osungunuka, padzakhala kutentha kwakukulu, komwe kumakhala 240 ℃, komwe kungayambitse kuwonongeka kwa inductor chifukwa cha kutenthedwa kwa kutentha.
3. Kugwiritsa ntchito chitsulo chosungunuka chamagetsi kuti muwotcherera chip inductor sikoyenera kwambiri, koma mukamafufuza ndi chitukuko cha injiniya, m'pofunika kugwiritsa ntchito chitsulo chosungunula chamagetsi kuti muwotchere chip inductors.Nazi zinthu zisanu zofunika kuziwona
(1) Preheat dera ndi inductor ku 150 ℃ pamaso kuwotcherera pamanja
(2) Chitsulo chogulitsira sichiyenera kukhudza thupi la chip inductor
(3)Gwiritsani ntchito chitsulo chogulitsira chokhala ndi ma watts 20 ndi 1.0 mm m'mimba mwake
(4) The soldering chitsulo kutentha ndi 280 ℃
(5)Nthawi yowotcherera siidutsa masekondi atatu
Kuti mudziwe zambiri, chonde omasukaLumikizanani nafe.
