Ekuhlolweni kwe-SMT, ukuhlola okubonakalayo kanye nokuhlolwa kwemishini yokubona kuvame ukusetshenziswa.Ezinye izindlela ziwukuhlola okubonwayo kuphela, kanti ezinye izindlela ezixubile.Bobabili bangahlola i-100% yomkhiqizo, kodwa uma indlela yokuhlola ebonakalayo isetshenziswa, abantu bazohlala bekhathele, ngakho-ke akunakwenzeka ukuqinisekisa ukuthi abasebenzi bahlola ngokucophelela i-100%.Ngakho-ke, sisungula isu elilinganiselayo lokuhlola nokuqapha ngokusungula izindawo zokulawula inqubo yekhwalithi.
Ukuze kuqinisekiswe ukusebenza okuvamile kwemishini ye-SMT, qinisa ukuhlolwa kwekhwalithi ye-workpiece yomshini ohlelweni ngalunye, ukuze kuqashwe ukusebenza kwayo, futhi kumiswe izindawo zokulawula ikhwalithi ngemva kwezinqubo ezithile ezibalulekile.
Lawa maphuzu okulawula ngokuvamile atholakala ezindaweni ezilandelayo:
1. Ukuhlolwa kwe-PCB
(1) Akukho ukuguqulwa kwebhodi eliphrintiwe;
(2) Ukuthi i-welding pad ine-oxidized;
(3) Akukho mihuzuko ebusweni bebhodi eliphrintiwe;
Indlela yokuhlola: Ukuhlolwa okubonakalayo ngokwezinga lokuhlola.
2. Ukutholwa kokuphrinta kwesikrini
(1) Ukuthi ukunyathelisa sekuphelile yini;
(2) Ukuthi likhona yini ibhuloho;
(3) Ukuthi ukujiya kuyafana;
(4) Akukho ukugoqa komphetho;
(5) Akukho ukuchezuka ekunyatheliseni;
Indlela yokuhlola: ukuhlola okubonakalayo noma ukuhlola ingilazi ekhulisayo ngokuya ngokwezinga lokuhlola.
3. Ukuhlolwa kwesichibi
(1) Ukuma kwezingxenye;
(2) Ukuthi kukhona iconsi;
(3) Azikho izingxenye ezingalungile;
Indlela yokuhlola: ukuhlola okubonakalayo noma ukuhlola ingilazi ekhulisayo ngokuya ngokwezinga lokuhlola.
4. Geza kabusha ihhaviniukutholwa
(1) Isimo sokushisela izingxenye, kungakhathaliseki ukuthi kukhona ibhuloho, i-stele, i-dislocation, ibhola le-solder, i-welding ebonakalayo kanye nezinye izenzakalo ezimbi zokushisela.
(2) Isimo se-solder joint.
Indlela yokuhlola: ukuhlola okubonakalayo noma ukuhlola ingilazi ekhulisayo ngokuya ngokwezinga lokuhlola.
