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 ELILUHLAZA 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.

1. 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.

1. Geza kabusha ibhodi futhi ulinganise iphrofayili yesikhathi sangempela esishisayo ngasikhathi sinye.
2. Hlola ikhwalithi ehlanganyelwe ye-solder, i-PCB kanye nesimo sengxenye.
3. Shisa ebhodini lokuhlola elinokushaqeka okushisayo nokushaqeka komshini ukuhlola ukwethembeka kwebhodi.
4. Qhathanisa idatha yesikhathi sangempela esishisayo nephrofayili ebonakalayo.
5. Lungisa ukusethwa kwepharamitha futhi uhlole izikhathi ezimbalwa ukuze uthole umkhawulo ophezulu kanye nomugqa ophansi wephrofayela yokugeleza kabusha kwesikhathi sangempela.
6. Londoloza amapharamitha athuthukisiwe njengokucaciswa kokugeleza kabusha kwebhodi eliqondiwe.
