Emhlabeni wokukhiqiza izinto zikagesi, ukusetshenziswa kwamabhodi esekethe aphrintiwe (ama-PCB) kubalulekile ekukhiqizeni izingxenye ze-elekthronikhi ezibalulekile ezinika amandla amadivaysi ethu ansuku zonke.Isici esiyinhloko somhlangano we-PCB ukusetshenziswa kwe-solder paste, esetshenziselwa ukunamathela izingxenye ze-electronic ebhodini lesifunda.Inqubo yokufaka i-solder paste kuma-PCB ngokwesiko yenziwe ngesandla, kodwa ngokuthuthuka kobuchwepheshe, amaphrinta we-PCB anamathisele isolder abe yithuluzi elibalulekile embonini yokukhiqiza ugesi.
Iphrinta ye-PCB yokunamathisela i-solder iwumshini osetshenziselwa ukufaka ngokunembile ukunamathisela kwe-solder kumaphedi e-PCB, okuqinisekisa ukunemba nokuvumelana kwenqubo yokunamathisela.Umshini usebenzisa i-stencil ukuze ufake i-solder paste ku-PCB, ususa isidingo sokufakwa ngesandla.Lokhu akugcini nje kusindisa isikhathi nezindleko zabasebenzi, kodwa futhi kuqinisekisa izinga eliphezulu lokunemba nokufana ngesikhathi senqubo yokushisela.
Ukusetshenziswa kwamaphrinta we-PCB solder paste kuguqule ukukhiqizwa kwe-elekthronikhi ngokwandisa kakhulu ukusebenza kahle kokukhiqiza kanye nokuthuthukisa ikhwalithi iyonke yemihlangano ye-PCB.Ngokuzenzakalela inqubo yokufaka isicelo sokunamathisela i-solder, abakhiqizi bangakhiqiza amabhodi wesifunda aphrintiwe ngokunemba okukhulu nokuvumelana, ekugcineni banciphise imingcele yamaphutha.
Ngaphezu kokunemba okuthuthukisiwe nokuvumelana, amaphrinta we-solder we-PCB anamathisele futhi anenzuzo yokunciphisa udoti wezinto ezibonakalayo.Uma isetshenziswe ngesandla, ukunamathisela kwe-solder okweqile kuvame ukuchithwa, okuholela ekukhuphukeni kwezindleko zempahla.Kodwa-ke, amaphrinta we-solder paste angahlelwa ukuthi asebenzise inani elifanele lokunamathisela kwe-solder, ukunciphisa imfucuza kanye nokonga imali ezintweni.
Ukwengeza, ukusebenzisa iphrinta yokunamathisela ye-solder kusiza ukunikeza indawo yokusebenza ephephile kubasebenzi.Ukuzenzakalela kwenqubo yokufaka i-solder paste kunciphisa ubungozi bezingozi zomsebenzi ngokuqeda ukuchayeka kwabasebenzi kumakhemikhali angaba yingozi ku-solder paste.
Ukuqaliswa kokuphrinta kwe-PCB solder paste nakho kuhambisana nokuphusha kwemboni kokusimama.Ngokunciphisa udoti wezinto ezibonakalayo kanye nokwenza ngcono ukusebenza kahle kokukhiqiza, abakhiqizi bangasebenza ngendlela enobungani nemvelo, okuya ngokuya kubaluleke kakhulu ebhizinisini lanamuhla lomhlaba.
Sekukonke, ukusetshenziswa kwamaphrinta we-PCB solder paste kuwushintsho lomdlalo embonini yokukhiqiza kagesi.Akugcini nje ngokuthuthukisa ukukhiqiza nekhwalithi yomkhiqizo, futhi kusiza ukudala indawo yokusebenza ephephile, neluhlaza.Njengoba ubuchwepheshe buqhubeka nokuthuthuka, singalindela ukubona okunye okusha ezinqubweni zokuhlanganisa ze-PCB ukuze kuthuthukiswe ukukhiqiza ngokuqhubekayo.
