Isokhethi yomsindo ye-PJ-320D ethengiswa kakhulu engu-3.5mm umakhi we-earphone

Isokhethi yomsindo ye-PJ-320D ethengiswa kakhulu engu-3.5mm umakhi we-earphone

Izinzuzo zomkhiqizo:

Ukulethwa okusheshayo, amasampula wamahhala, ahambisana ne-RoHS, impilo yomjikelezo wezikhathi ezingama-5000,isevisi eqinisekisiwe yangemva kokuthengisa, ukwesekwa kobuchwepheshe nesimo esihle sesevisi

Amandla efekthri:

Iminyaka eyishumi nantathu yesipiliyoni sembonini, inkampani isiphumelele isitifiketi se-ISO9001, izitifiketi eziningi zelungelo lobunikazi, amakhasimende asebenzisanayo angaphezu kuka-5000, amakhasimende amaningi ezinkampani ezisohlwini, abasebenzi abayi-106, amapuntshi wehardware ayi-12, imishini yokubumba imijovo eyi-18, imishini yokuhlanganisa ezenzakalelayo engama-26 egcwele. , imishini yokuhlola ezenzakalelayo engama-32, imishini yokuhlola i-semi-automatic engama-21, imishini yokuhlola impilo eyi-12 nezinye izinto zokuhlola

Umkhiqizo wethu ungaphumelela lezi zivivinyo ezingezansi:

1) ukuhlolwa kwe-solderability

ingaphezulu lamatheminali lizocwiliswa ngo-1mm kubhavu we-solder ongu-240±5℃ imizuzwana engu-3±0.5

2) ukumelana nezimo ze-soldering test reflow soldering:

preheat: izinga lokushisa phezu ucwecwe zethusi surface kufanele sifinyelele 180 ℃.120s ngemva pcb

yangena emishinini yokuhlanganisa.izinga lokushisa eliphakeme kunawo wonke: izinga lokushisa endaweni ye-copper foil kufanele lifinyelele izinga lokushisa eliphakeme elingu-260±5℃ ngemizuzwana engu-20.

3) ukumelana nokuhlolwa kokushisa kwe-solder

Indlela ye-Soldering iron:

izinga lokushisa elincane 330±5℃ isicelo

isikhathi sokugcwalisa i-iron3±0.5 sec

nokho ukucindezela okukhulu akumele kusetshenziswe kutheminali

4) ukuhlolwa komswakama

ujeke uzogcinwa ezingeni lokushisa

ka-40±2℃ kanye nomswakama ongu-90% kuya ku-96% amahora angu-96, khona-ke ujeke uzogcinwa usesimweni esijwayelekile somkhathi ihora elingu-1 kwezinye izinqubo.

5) ukuhlolwa kokushisa

Iifoniujeke uzogcinwa ezingeni lokushisa elingu-70±2℃ amahora angama-96,futhi emva kwalokho izofakwa ngaphansi kwembasurbm yokutakula elawulwayo

6) ukuhlolwa okubandayo

ujeke uzogcinwa ekushiseni okungama-25±3℃ amahora angama-96 bese ubekwa ngaphansi kwezimo ezilawulwayo zokuthola kabusha ihora elingu-1 ngemuva kwalokho.

7) ukuhlolwa kwempilo

esimweni sokulinganisa(umthwalo ongenayo inductive）

uxhumano kanye nokunqanyulwa kuzokwenziwa 5000 imijikelezo ngesivinini 10 ukuze 20 imijikelezo / min.

8) ukuhlolwa kokushaqeka okubandayo nokushisa

ujeke uzobhekana nemijikelezo emi-5 yalezi zimo ezilandelayo ezikhonjiswe emfanekisweni, bese ibuya futhi ivunyelwe ukuhlala esimweni segumbi imizuzu engama-30..

Tlapha ngeke kube khona ukuwohloka noma imifantu engxenyeni ebunjiwe.Ukufakwa&amandla okukhipha:3 kuya ku-20n

ukumelana nokuxhumana: max.30mω

ukumelana nokwahlukanisa: min.100 mω

I-dielectric withstanding voltage: 500vac/min(phakathi kwamatheminali)
