Njengoba ama-chip inductors enezici ezifana ne-miniaturization, ikhwalithi ephezulu, isitoreji samandla aphezulu, ne-DCR ephansi kakhulu, kancane kancane ithathe indawo yama-plug-in inductors emikhakheni eminingi. Njengoba imboni ye-elekthronikhi ingena enkathini ye-miniaturization kanye ne-flattening, ama-chip inductors aya ngokuya esetshenziswa ezinhlobonhlobo zezinhlelo zokusebenza. Ngesikhathi esifanayo,ama-chip inductorsezincane nezincane, nazo eziletha ubunzima ekushiseleni i-chip inductor.
Izinyathelo zokuphepha ze-welding preheating
Ngenxa yobukhulu bayo obuncane nobuncane, kunomehluko omningi phakathi kokudayiswa kwama-chip inductors nama-plug-in inductors. Yini okufanele inakwe lapho i-soldering chip inductors?
1. Ngaphambi kokushisela i-chip inductor, kubalulekile ukunaka ukufudumala ukuze ugweme ukushaqeka okushisayo ngesikhathi sokushisela.
2. Izinga lokushisa langaphambi kokushisa lidinga ukunyuka okunensayo, okungcono okungu-2 ℃/sec, futhi akumele lidlule u-4 ℃/sec.
3. Qaphela umehluko wezinga lokushisa phakathi kwezinga lokushisa lokushisela kanye nezinga lokushisa elingaphezulu Ngokuvamile, umehluko wezinga lokushisa phakathi kuka-80 ℃ no-120 ℃ uvamile.
4. Ngesikhathi se-welding, kufanele kuqashelwe ukuthi ukushaqeka okushisayo kuzokwanda ngokunyuka kosayizi we-chip inductor noma izinga lokushisa.
I-Solderability
Ukucwiliswa kobuso bokugcina be-chip inductor esithandweni sothayela ku-235 ± 5 ℃ imizuzwana engu-2 ± 1 kungazuza imiphumela emihle yokunamathisela.
Ukusebenzisa i-flux ngesikhathi sokushisela
Ukukhetha i-soldering flux efanele kusiza ukuvikela indawo ye-inductor. Phawula amaphuzu alandelayo.
1.Qaphela ukuthi akumele kube nama-acids aqinile ku-flux lapho ushisela i-inductor yesichibi. Isetshenziswa ngokujwayelekile ukwenza kusebenze i-rosin flux ethambile.
2.Uma i-flux e-soluble yamanzi ikhethiwe, ukunakwa okukhethekile kufanele kukhokhwe ekuhlanzekeni kwe-substrate ngaphambi kwe-welding.
3.Ngokwesisekelo sokuqinisekisa ukushisela okuhle, qaphela ukusebenzisa i-flux encane ngangokunokwenzeka.
Izinyathelo zokuqapha inqubo ye-welding
1.Sebenzisa i-reflow soldering ngangokunokwenzeka ukuze ugweme ukuhlanganisa ngesandla.
2.Qaphela ukuthi i-wave soldering ayinconywa kuma-chip inductors amakhulu kunosayizi we-1812. Ngoba lapho i-chip inductor icwiliswa kugagasi lokushisela elincibilikisiwe, kuzoba nokukhuphuka kwezinga lokushisa okuphakeme, ngokuvamile okungu-240 ℃, okungase kubangele ukulimala kwe-inductor ngenxa yokushaqeka okushisayo.
3. Ukusebenzisa i-iron soldering kagesi ukushisela i-chip inductor akufanelekile kakhulu, kodwa uma kucwaningo lonjiniyela kanye nenqubo yokuthuthukiswa, kuyadingeka ukusebenzisa insimbi yokunamathisela kagesi ukuze ushise ama-chip inductors. Nazi izinto ezinhlanu okufanele uziqaphele
(1) Shisisa isekethe kanye ne-inductor ku-150 ℃ ngaphambi kokushisela ngesandla
(2)Insimbi yokunamathisela akufanele ithinte umzimba we-chip inductor
(3)Sebenzisa insimbi yokunamathisela enamawathi angu-20 nobubanzi obungu-1.0 mm
(4) Izinga lokushisa lensimbi ehlanganisiwe lingu-280 ℃
(5)Isikhathi sokushisela akumele sidlule imizuzwana emithathu
Ukuze uthole ulwazi olwengeziwe, sicela ukhululeke ukuXhumana nathi.
