Isaziso
■ Emva kokuba ixesha lokugcina izinto ezisandula ukuthengwa lidlule iinyanga ezi-6, kufuneka kuqwalaselwe ukuba ziyashibilika na ngaphambi kokuba zisetyenziswe. Kucetyiswa ukuba zigcinwe kwiphakheji ye-vacuum.
■ Phula umngxuma oshushu kwi-PCB uze ugcwalise i-solder.
■ Ukuwelda kwe-Reflow kukhethwa xa kuwelda ezantsi, nceda ujonge intshayelelo ye-Reflow
■ Ukuze kuhlangatyezwane neemfuno zemizobo, kufuneka kufakwe i-radiator enobukhulu obaneleyo.
■ Yongeza ukupholisa umoya okanye ukupholisa ngamanzi ukuba kuyimfuneko.
◆ Imiyalelo:
■ Ii-RF attenuators ezenzelwe wena, ii-RF resistors kunye nee-RF terminals ziyafumaneka.
■ Ukuze kuhlangatyezwane neemfuno zomzobo, kuyimfuneko ukufaka i-radiator enkulu ngokwaneleyo. Imiphezulu yesinyithi kunye nee-radiator kufuneka zigqunywe ngomaleko omncinci kakhulu wegrisi yobushushu.
■ Yongeza ukupholisa umoya okanye ukupholisa ngamanzi ukuba kuyimfuneko.
