Umgangatho wentsimbi yentsimbi kwibhodi yePCBA

Umgangatho owamkelekileyo wobungakanani bentsimbi yenkcenkce kumphezulu webhodi ye-PCBA.

1.Idayamitha yebhola yetoti ayidluli kwi-0.13mm.

2.Inani lamaso e-tin kunye nobubanzi be-0.05mm-0.13mm ngaphakathi koluhlu lwe-600mm alukho ngaphezu kwe-5 (icala elinye).

3. Inani lamaso e-tin kunye nobubanzi obungaphantsi kwe-0.05mm ayifuni.

4. Onke amaso e-tin kufuneka asongelwe yi-flux kwaye ayinakushukunyiswa (i-flux efakwe ngaphezu kwe-1/2 yobude be-tin beads ihlanganiswe).

5. Amaso enkcenkce awazange anciphise ukucocwa kombane kwiikhondatha zenethiwekhi ezahlukeneyo ukuya ngaphantsi kwe-0.13mm.

Qaphela: Ngaphandle kweendawo ezikhethekileyo zolawulo.

Iikhrayitheriya zokukhatywa kwamaso enkcenkce:

Nakuphi na ukungathotyelwa kweekhrayitheriya zokumkelwa kugwetyelwa ukukhatywa.

Amagqabantshintshi:

1. Indawo yolawulo olukhethekileyo: amaso e-tin abonakalayo phantsi kwe-20x microscope awavumelekanga ngaphakathi kwe-1mm ejikeleze i-capacitor pad kwisiphelo somnwe wegolide womgca wesignali yokwahlukana.
2. Amaso enkcenkce amele isilumkiso senkqubo yokwenziwa kwemveliso.Ngoko ke abavelisi beetshiphu ze-SMT kufuneka baqhubeke bephucula inkqubo yokunciphisa ukwenzeka kwentsimbi yenkcenkce.
3. Umgangatho wokuhlolwa kwenkangeleko ye-PCBA yenye yezona migangatho zisisiseko zokwamkelwa kweemveliso zombane.Ngokweemveliso ezahlukeneyo kunye neemfuno zabathengi, iimfuno ezamkelekileyo zamaso enkcenkce nazo ziya kwahluka.Ngokuqhelekileyo, umgangatho unqunywe ngokusekelwe kumgangatho wesizwe kwaye udibene neemfuno zabathengi.

I-PCBFuture ngumvelisi we-PCB kunye nomvelisi wendibano ye-PCB ebonelela ngemveliso ye-PCB yobungcali, ukuthengwa kwezinto eziphathekayo, kunye nenkonzo ekhawulezayo ye-PCB yokumisa enye.
