Ekuhlolweni kwe-SMT, ukuhlolwa okubonakalayo kunye nokuhlolwa kwezixhobo ezibonakalayo zihlala zisetyenziswa.Ezinye iindlela kukuhlola okubonwayo kuphela, kwaye ezinye ziindlela ezixutyiweyo.Bobabini banokuhlola i-100% yemveliso, kodwa ukuba indlela yokuhlola ebonakalayo isetyenzisiweyo, abantu baya kuhlala bediniwe, ngoko akunakwenzeka ukuqinisekisa ukuba abasebenzi bayi-100% yokuhlolwa ngokucophelela.Ngoko ke, siseka isicwangciso esilungeleleneyo sokuhlola kunye nokubeka iliso ngokuseka iindawo zokulawula inkqubo yomgangatho.
Ukuze kuqinisekiswe ukusebenza okuqhelekileyo kwezixhobo ze-SMT, qinisa ukuhlolwa komgangatho we-machining workpiece kwinkqubo nganye, ukuze kubekwe iliso kwimeko yokusebenza kwayo, kwaye kumiselwe iindawo zokulawula umgangatho emva kweenkqubo ezithile eziphambili.
Ezi ndawo zolawulo zikholisa ukubekwa kwezi ndawo zilandelayo:
1. Ukuhlolwa kwePCB
(1) Akukho lutshintsho lwebhodi eshicilelweyo;
(2) Ingaba i-welding pad i-oxidized;
(3) Akukho mikrwelo kumphezulu webhodi eprintiweyo;
Indlela yokuhlola: Ukuhlolwa okubonwayo ngokomgangatho wokuhlola.
2. Ukubona ukuprintwa kwesikrini
(1) Enoba ushicilelo lugqityiwe;
(2) Ingaba kukho ibhulorho;
(3) Ingaba ubukhulu bufana;
(4) Akukho kuwela komphetho;
(5) Akukho kutenxa kushicilelo;
Indlela yokuhlola: ukuhlolwa okubonakalayo okanye ukuhlolwa kweglasi yokukhulisa ngokomgangatho wokuhlola.
3. Uvavanyo lwepetshi
(1) Indawo yokuxhoma yamacandelo;
(2) Nokuba kukho ithontsi;
(3) Akukho malungu angalunganga;
Indlela yokuhlola: ukuhlolwa okubonakalayo okanye ukuhlolwa kweglasi yokukhulisa ngokomgangatho wokuhlola.
4. Hlaziya i-oveniukubhaqwa
(1) Imeko ye-welding yamacandelo, nokuba kukho ibhulorho, i-stele, i-dislocation, ibhola ye-solder, i-welding virtual kunye nezinye izinto ezimbi ze-welding.
(2) Imeko ye-solder joint.
Indlela yokuhlola: ukuhlolwa okubonakalayo okanye ukuhlolwa kweglasi yokukhulisa ngokomgangatho wokuhlola.
