Uyilungiselela kanjani iphrofayili yokugeleza kabusha?
Ngokwezincomo zenhlangano ye-IPC, i-generic Pb-freeukugeleza kabusha kwe-solderiphrofayili ikhonjisiwe ngezansi.Indawo ELUHLAZA iyibanga elamukelekayo layo yonke inqubo yokugeleza kabusha.Ingabe kusho ukuthi yonke indawo kule ndawo ELUHLAZA kufanele ilingane nesicelo sakho sokugeleza kabusha kwebhodi?Impendulo ithi CHA!
Umthamo oshisayo we-PCB uhlukile ngokuya ngohlobo lwezinto ezibonakalayo, ukujiya, isisindo sethusi ngisho nokuma kwebhodi.Kuphinde kwehluke kakhulu lapho izingxenye zimunca ukushisa ukuze zifudumale.Izingxenye ezinkulu zingadinga isikhathi esiningi ukuze zishise kunezincane.Ngakho-ke, kufanele uhlaziye ibhodi lakho olihlosile kuqala ngaphambi kokudala iphrofayela ehlukile yokugeleza kabusha.
- Yenza iphrofayela ye-reflow ebonakalayo.
Iphrofayili yokugeleza kabusha ebonakalayo isuselwe kumbono wokudayiswa, iphrofayela enconyiwe ye-solder evela kumkhiqizi we-solder unama, usayizi, ukujiya, isisindo se-cooper, izendlalelo zebhodi nosayizi, kanye nokuminyana kwezingxenye.
- Geza kabusha ibhodi futhi ulinganise iphrofayili yesikhathi sangempela esishisayo ngasikhathi sinye.
- Hlola ikhwalithi ehlanganyelwe ye-solder, i-PCB kanye nesimo sengxenye.
- Shisa ebhodini lokuhlola elinokushaqeka okushisayo nokushaqeka komshini ukuhlola ukwethembeka kwebhodi.
- Qhathanisa idatha yesikhathi sangempela esishisayo nephrofayili ebonakalayo.
- Lungisa ukusethwa kwepharamitha futhi uhlole izikhathi ezimbalwa ukuze uthole umkhawulo ophezulu kanye nomugqa ophansi wephrofayela yokugeleza kabusha kwesikhathi sangempela.
- Londoloza amapharamitha athuthukisiwe njengokucaciswa kokugeleza kabusha kwebhodi eliqondiwe.
