Enyanisweni, i-soldering yinyathelo elibaluleke kakhulu kwimveliso ye-inductors, kodwa engahlawulwanga ngqalelo enkulu. Kuyimfuneko kakhulu ukuba silungelelanise iindlela ezifanelekileyo zokudibanisa ii-inductors zenxeba le-SMD ukuqinisekisa ukuba ukusebenza kwethu kwe-inductor kunamandla ngakumbi. Ngoku ndiza kubelana nawe ngezizathu ezininzi zokungathengiswa kakuhle kweInductor yomoya ye-SMD, ngethemba lokukunceda.
1. I-oxidation okanye into yangaphandle kwi-inductor soldering pad
Ukuthengiswa kakubi kwee-inductors zenxeba ze-SMD, i-oxidation okanye into yangaphandle kwi-inductor pad sisizathu esiqhelekileyo esibangela ukuthengiswa kakubi kwee-inductors ezahlukeneyo.
2. Kukho i-burr kwi-soldering pad ye-SMD inductor
Kukho inkqubo yokusika umlenze kwimveliso ye-SMD inductor. Kule nkqubo, ukuba i-cutter ayigcinwanga kakuhle, kulula ukubangela i-burr kwi-inductor soldering pad. Kule meko, kuya kubangela ukuncamathisela okungalinganiyo kwe-inductor, okukhokelela ekudibaniseni kakubi.
3. Unyawo olugobayo lwe-SMD inductor soldering pad alulingani
Kwiimeko eziqhelekileyo, iipads kwiziphelo zombini ze-inductor kufuneka ziqhotyoshelwe ngokupheleleyo kwi-solder paste yebhodi ye-PCB. Nangona kunjalo, ukuba i-inductor pads ayigobekanga ngokufanelekileyo ngexesha lokusebenza kokugoba unyawo, kuya kubangela ukuba isiphelo se-inductor sibe ne-warped, okubangela ukuba i-welding ingabikho.
4. I-inductor body groove inzulu kakhulu
Kukho iigrooves ezimbini kumzimba we-SMD inductor. Ezi grooves zimbini yindawo emva kokuba i-inductor pad pin igobile. Nangona kunjalo, ukuba i-inductor groove inzulu kakhulu, inkulu kunobunzima bephepha lephedi, nangona i-inductor ifakwe kwibhodi ye-PCB, i-pad inductance inqunyanyisiwe kwaye ayidibanisi ne-solder paste, okukhokelela ekudibaniseni kakubi. .
5. Iingxaki kwinkqubo yokwenziwa kwabathengi
I-solder engafanelekanga ye-inductor ye-SMD ayikho kuphela ingxaki ye-inductor ngokwayo. Kwiimeko ezininzi, ngenxa yeengxaki zenkqubo yokwenziwa komthengi, kuya kukhokelela kwi-solder engafanelekanga ye-inductor, efana neqondo lokushisa eliphantsi lokubuyisela i-solder paste kunye nokungonelanga kwe-reflow solder.
Ingqwalasela engakumbi kufuneka ihlawulwe kwiingxaki ezingentla kwinkqubo ye-welding ye-SMD winding inductor ukunciphisa izinto ezingathandekiyo kwinkqubo ye-welding.
