Ndipotu, soldering ndi sitepe yofunikira kwambiri pakupanga ma inductors, koma omwe salipidwa kwambiri. Ndikofunikira kwambiri kuti tisinthe njira zololera zowotcherera mabala a SMD kuti tiwonetsetse kuti magwiridwe antchito athu amphamvu kwambiri. Tsopano ine ndikugawana nanu zifukwa zingapo osauka soldering waSMD winding inductor, ndikuyembekeza kukuthandizani.

1. Oxidation kapena zinthu zakunja pa inductor soldering pad

Kusasunthika koyipa kwa ma inductors a bala a SMD, ma oxidation kapena zinthu zakunja pa inductor pad ndizifukwa zodziwika bwino zomwe zimayambitsa kusokonekera kwa ma inductors osiyanasiyana.

2. Pali burr pa soldering pad ya SMD inductor

Pali njira yodulira miyendo popanga SMD inductor. Pochita izi, ngati wodulayo sakusamalidwa bwino, ndizosavuta kuyambitsa burr pa inductor soldering pad. Pankhaniyi, zingayambitsenso kusagwirizana kwa inductor, zomwe zimapangitsa kuti kuwotcherera bwino.

3. Phazi lopindika la SMD inductor soldering pad ndilosiyana

Munthawi yanthawi zonse, mapadi pa malekezero onse a inductor ayenera kumangirizidwa kwathunthu ndi phala la solder la bolodi la PCB. Komabe, ngati mapadi a inductor sakupindika bwino panthawi yopindika phazi, zimapangitsa kuti mapeto a inductor asokonezeke, zomwe zimapangitsa kuwotcherera bwino.

4. The inductor body groove ndi yakuya kwambiri

Pali ma grooves awiri pa SMD inductor body. Ma groove awiriwa ndi malo pambuyo poti pini ya inductor ipindike. Komabe, ngati inductor groove ndi yozama kwambiri, yomwe ndi yaikulu kuposa makulidwe a pepala la pad, ngakhale kuti inductor imakhala yokhazikika pa bolodi la PCB, inductance pad imayimitsidwa ndipo sichikhudzana ndi phala la solder, zomwe zimapangitsa kuti pakhale kuwotcherera bwino. .

5. Mavuto pakupanga makasitomala

Kugulitsa koyipa kwa inductor ya SMD si vuto la inductor palokha. Nthawi zambiri, chifukwa cha mavuto a kasitomala kupanga ndondomeko, zidzachititsanso osauka soldering wa inductor, monga otsika solder phala kubwerera kutentha ndi osakwanira reflow soldering kutentha.

Chisamaliro chochulukirapo chiyenera kuperekedwa ku zovuta zomwe zili pamwambapa pakuwotcherera kwa SMD winding inductor kuti muchepetse zochitika zosafunikira pakuwotcherera.

Ngati mukufuna, chonde omasukaLumikizanani nafekwa mafunso ena.
