Njengoba sonke sazi, iI-SMTumshiniingasetshenziswa ukukhweza izinhlobo eziningi zezingxenye, ngakho-ke ngokuvamile siwubiza ngokuthi umshini we-SMT osebenzayo, sisebenzisa inqubo ye-SMT abantu abaningi abanemibuzo, hlobo luni lwezingxenye olungafakwa?Okulandelayo, sizochaza izinhlobo ezine zezingxenye zentaba evamileI-PNPumshini:
- resistor: ngokuvamile singasebenzisa pick bese sibeka umshini ukukhweza resistor phezu kwesici.Ngokuvamile, singakwazi ukuveza usayizi wamanje wokumelana ngamamilimitha noma amayintshi.Kunezinombolo ezine kwi-resistor.Amabili okuqala amelela ubude bokumelana, kanti amabili okugcina amelela ububanzi bokumelana.Uma siyifaka kabusha, inqobo nje uma ingaphakathi kwebanga lephutha lokuyifaka, ingabhekwa njengento efanelekile yokumelana nokufaka futhi ukusetshenziswa kwayo ngeke kuthinteke.
- I-Capacitor: kunezinhlobo eziningi zama-capacitor, ama-capacitor e-ceramic nama-electrolytic capacitors avame ukusetshenziswa.Ama-Capacitor anezinhlaka ezine eziyinhloko, amandla, usayizi, iphutha kanye ne-coefficient.Ama-Capacitor nawo angafakwa ezingxenyeni ngomshini wokukhweza.Ngokuvamile, inani le-capacitance ye-capacitor lingaboniswa ngamadijithi amathathu kusici, kodwa kuma-capacitors e-ceramic, lesi sinyathelo singashiywa.Singakwazi ukuhlukanisa ama-capacitor ahlukene ngokusho kombala, usayizi kanye nemodeli ye-capacitor efakiwe.
- I-Inductance: I-inductance iyafana ngomumo ukuze ibe namandla, kodwa imnyama ngombala kune-capacitance.Ngaphambi kokufaka, singasebenzisa umtshina ukuhlukanisa i-inductance kanye nosayizi we-inductance, bese sinquma ukuthi i-inductance yamanje efakiwe iyafana yini ne-inductance, futhi ekugcineni i-chip izocutshungulwa yi-patch.
- I-Diode: i-diode nayo isetshenziswa kabanzi embonini ye-SMT.Ingilazi ne-plastic-sealed diode yizinhlobo ezivamile zokufakwa futhi zinezinhlelo zokusebenza eziningi ekuphileni kwansuku zonke, njengama-LED asetshenziswa kumakhalekhukhwini.Ama-Diodes ezinto ezahlukene angakhipha ukukhanya kwemibala ehlukene.Ukubeka kahle nge-ai-chip mounterumshinikuyindlela enqamulelayo yokukhiqiza ngobuningi.
