Izimo zokushisa kanye nomswakama kufanele kube yizincomo zomenzi ukuqinisekisa ukuthi i-Adhesive ihlala isebenza kahle. Ukwengeza, okunamathelayo kwe-SMT kufanele kugcinwe esitsheni saso sokuqala nesivalo esivalwe ngokuqinile ukuze kuvinjelwe ukungcola noma ukuhwamuka.
3. Ukulahlwa: Ukulahlwa okufanele kokunamathela kwe-SMT kubalulekile ukuze kuncishiswe umthelela ongaba khona kwezemvelo. Noma yiziphi izinamathiselo ezingasetshenzisiwe noma eziphelelwe yisikhathi kufanele zilahlwe ngemithetho yendawo kanye neziqondiso. Lokhu kungase kuhlanganise ukuyiyisa endaweni yokulahla imfucuza eyingozi noma ukuthintana nenkampani ekhethekile elawula udoti ukuze ulahlwe ngendlela efanele.
4. Ukuchitheka nokuvuza: Uma kuwa noma kuvuza, ukuhlanza indawo ngokushesha kubalulekile ukuze kuvinjelwe ukungcoliswa okwengeziwe. Lokhu kungase kuhlanganise ukusebenzisa izinto ezimuncayo njengesihlabathi noma ubumba ukuze kuqukethe ukuchitheka nokuhlanza indawo ngesincibilikisi esifanelekile noma isihlanzi.
5. Ukuqeqeshwa: Ukuqeqeshwa okufanele kanye nemfundo kufanele kunikezwe abasebenzi abaphatha izinto zokunamathisela ze-SMT. Lokhu kufanele kubandakanye ulwazi lokuphatha kahle, ukugcinwa, nokulahlwa kwe-Adhesive kanye nokusetshenziswa kahle kwe-PPE kanye nezinqubo zokusabela ezimeni eziphuthumayo uma kwenzeka ingozi noma kuchitheka.

Ngokulandela lezi zindlela ezingcono kakhulu zokuphatha, ukugcinwa, kanye nokulahla okunamathelayo kwe-SMT, abakhiqizi bangaqinisekisa ukuphepha nokusebenza kwe-Adhesive kuyilapho benciphisa noma yiziphi izingozi ezingaba khona noma umthelela wendawo. Kubalulekile ukubonana nemiyalelo yomkhiqizi, imithetho yendawo, kanye nemihlahlandlela ukuze uthole izincomo nezimfuneko ezithile.

Isiphetho:

Ukunamathela kwe-SMT kuguqule ukukhiqizwa kwe-elekthronikhi ngokuthuthukisa ukuthembeka komkhiqizo kanye nokwenza kube lula ukubekwa kwengxenye. Uhlu olubanzi lwezinketho zokunamathela ezitholakalayo, intuthuko kumasu okusabalalisa, nokucatshangelwa kwemvelo kwenze ukunamathela kwe-SMT kwaba ingxenye ebalulekile ezinqubweni zokukhiqiza zesimanje. Njengoba imboni ithuthuka, abakhiqizi kufanele bahlale benolwazi ngentuthuko yakamuva kanye nezinqubo ezihamba phambili ezihambisana nezinamatheliso ze-SMT ukuze kukhuliswe ukusebenza kahle, isivuno, kanye nekhwalithi yomkhiqizo iyonke. Ngokusebenzisa amandla okunamathela kwe-SMT, abakhiqizi bangavula amathuba amasha ekukhiqizeni izinto zikagesi, okuholela ekusebenzeni okuthuthukisiwe nokwaneliseka kwamakhasimende.
