Izingxenye zomugqa wokukhiqiza we-SMT:

Ulayini wokukhiqiza we-SMT uqukethe izingxenye ezingazodwana ezisebenza ngokuvumelanisa ukuze kuqinisekiswe inqubo yokukhiqiza eshelelayo.Lezi zingxenye ezibalulekile zihlanganisa:

1. Umshini we-SMT: Umnyombo weUmugqa wokukhiqiza we-SMTumshini onesibopho sokubeka izingxenye ze-elekthronikhi ku-PCB.Eyaziwa njengemishini yokukhetha nendawo, le mishini isebenzisa izingalo zerobhothi namanozzles okukhipha umoya ukuze ikhethe izingxenye kusuka kusiphakeli futhi izibeke ngokunembile ku-PCB.

2. I-oven yokugeleza kabusha: Ngemva kokuhlanganiswa, i-PCB idlula kuhhavini lokugeleza kabusha lapho i-solder paste esetshenziselwa ukubamba izingxenye endaweni iyancibilika futhi iqine, yakhe isibopho esiqinile.I-ovini yokugeleza kabusha iqinisekisa ukuthi amalunga e-solder akhiwe ngendlela efanele futhi izingxenye zinamathiselwe ngokuphephile ku-PCB.

3. Iphrinta yokunamathisela ye-Solder: Ukusetshenziswa okunembile kokunamathisela kwe-solder kubalulekile kunqubo ye-SMT.Iphrinta yokunamathisela ye-solder isebenzisa i-stencil ukuze ifake i-solder paste ku-PCB, iqinisekisa ukuqondana okunembayo namaphedi.

4. Uhlelo Lokuhlola: Ukuze kugcinwe amazinga ekhwalithi, wonke umugqa wokukhiqiza wamukela uhlelo lokuhlola.Imishini ye-Optical Inspection (AOI) ezenzakalelayo ihlola ukukhubazeka okufana nezinto ezingekho noma ezingaqondani kahle, ukonakala kwe-soldering, nokonakala kwe-PCB.Amasistimu okuhlola ama-X-ray nawo asetshenziswa ukuze kutholwe amaphutha afihlekile, njengamajoyinti e-solder anganele.
