Umbhali kwaye umthetho wokuhlanganisa kwesondulo esisetyenziselwe

Ukukuhlanganisa kwesondulo esisetyenziselwe iyindlela yokuhlola okanye lokuhlola amandla nokuba ngokushesha phakathi komphendvo wesondwana olusetyenziselwe nokulandelana namaphrofayile ahlola esisetyenziselwe, ngekhonjane lomkhuhlane lwesondulo elibekwe ngaphambili kwisebhedlela sesondulo. ukusondeza.

Umbhali wokuqinisekiswa kokuhlanganisa kwesondulo esisetyenziselwe

Isikhombisi sasendaweni esizityenziselwe sihamba ngaphandle kwindawo yesondwana somkhuhlane sokuthutha, uphase kwindawo lokuhlola, indawo yokuhlola, indawo yokusondeza kunye nondawo lokugcina lokhu.

A. Xa i-PCB iyenza isigaba somphumelelo, umsebenzi kanye ne-gas esintshwene ngokubhulukwe. Ngokuqondile, u-flux esintshweni kuhlala kwi-padz, amandla omlilo nokupinini, kunye ne-solder paste okungathathwa, ukhupha, kunye nokuhlala ofakadeyo esintshweni.

B. Xa i-PCB iyenza isigaba somphumelelo sokugcina, i-PCB namandla azikhululekile ngaphambili ukuvula ukuba i-PCB asikholele kulandelayo lwehluko lokuncane ukusuka kwisebe sengxenyeni lokuhlola futhi ukusisusa i-PCB namandla.

C. Xa i-PCB iyenza isigaba somhlolo, umphelo uphuma ngqukuqambo ngenxa yokuba le-solder paste liyinto olunemoya olushayisiwe, ulwandle lwesintshweni lufaka, luchaza, luchaza, noma luyiflow ipadz, amandla omlilo nokupinini we-PCB ukusetshenziswa imibhalo yesintshweni.

D. I-PCB iyenza isigaba soluhlola ukusetha imibhalo yesintshweni; xa kusebenza ukufika kwesintshweni.

Isiphumo Sokufika Kwesintshweni

"Ukuxhuma kwakhona" kungenxa yokuba igesi ijikeleza kumatshini wokusongela ukuvelisa ubushushu obuphezulu ukufezekisa injongo yokusongela. Yokuhambisa ibhodi yesekethe kunye nezinto ze-SMD ezifakwe kwigumbi lokudibanisa i-SMT, emva koko ubeke i-solder paste esetyenziselwa ukudibanisa izinto ze-SMD emva kobushushu obuphezulu. Inkqubo yokwenza utshintsho lobushushu obubuyela umva ngokusebenzisa ubushushu obuphezulu bomoya oshushu unyuka, ukuze izinto zeplagi zidityaniswe neepads kwibhodi yesekethe, kwaye emva koko zipholile kwaye zilungiswe kunye. Isishwankathelo esipheleleyo Injongo yokuxhuma kwakhona kukudlulisa izinto ze-SMT ze-patch zezikhonkwane ezingasebenziyo nge-Paste ye-solder kunye nebhodi yesekethe zilungiswa kunye ukwenza ibhodi yesekethe ye-PCBA egqityiweyo eneempawu ezithile zombane.
