Yini iphutha lebhola le-solder?

Ibhola lomthengisi lingenye yezinto eziphindwe kasikhombisi ezitholakala lapho zifaka izicelo zobuchwepheshe be-surce Mount kubhodi yokujikeleza ephrintiwe. Ngokuvumelana negama labo, bayibhola lomthengisi elihlukanise nomzimba omkhulu owakha izingxenye ezihlangene ezihlanganayo zentaba ebhodini.

Amabhola we-Solerd anezinto zokwenziwa, okusho ukuthi uma zigoqa ebhodini lesekethe eliphrintiwe, zingadala izikhindi zikagesi, zithinte kabi ukuthembeka kwebhodi lesekethe eliphrintiwe.

NgeIPC-A-610, i-PCB enamabhola angaphezu kuka-5 (<= 0,13mm) ngaphakathi kwe-600mm² ayinaphutha, njengoba ububanzi obukhulu kune-0.13mm yephula umthetho we-lela kagesi we-0.1MMM. Kodwa-ke, yize le mithetho isho ukuthi amabhola abathengisi angashiywa eqinile uma ebambelele ngokuphephile, ayikho indlela yangempela yokwazi esiqinisekile uma kunjalo.

Ungayilungisa kanjani amabhola womthengisi ngaphambi kokwenzeka

Amabhola we-Solerd angabangelwa yizici ezahlukahlukene, enza ukuxilongwa kwenkinga enzima. Kwezinye izimo, zingaba okungahleliwe ngokuphelele. Nazi izizathu ezimbalwa ezijwayelekile ze-Soler Amabhola we-PCB CHARCY PROCTE.

Ukuswakama-UbumanziKuzonda kwaba ngolunye lwezingqinamba ezinkulu zabakhiqizi beBhasikene Bokuphrinta namuhla. Ngaphandle komthelela we-poporcorn kanye nokuqhekeka okuyi-microscopic, kungadala futhi amabhola we-solder ukuba akha ngenxa yokuphunyuka komoya noma kwamanzi. Qinisekisa ukuthi amabhodi wesifunda aphrintiwe azomiswa kahle ngaphambi kokusetshenziswa kwe-WED, noma enze izinguquko ukulawula umswakama endaweni yokukhiqiza.

Ukunamathisela ku-solder- Izinkinga ku-solder paste uqobo zingafaka isandla ekwakhekeni kwe-solder balling. Ngakho-ke, akululiwe ukuthi usebenzise kabusha ukunamathisela okuthengiswayo noma ukuvumela ukusetshenziswa kwe-solder anamathisela kudlule usuku lokuphelelwa kwalo. U-solder paste kumele futhi ugcinwe kahle futhi waphathwa ngemihlahlandlela yomenzi. Ama-solder solce solce ancibilikayo nawo angafaka isandla emsimbini owengeziwe.

Idizayini ye-Stencil- Ukulingisa kwe-soler kungenzeka lapho kuhlanzwa nge-stencil ngokungafanele, noma lapho kufakwe khona i-stencil. Ngakho-ke, ukwethemba ionolwazi ukuphrinta ukuphrinta kwebhodi lokuphrintaFuthi indlu yomhlangano ingakusiza ugweme la maphutha.

Thwebula iphrofayili yokushisa- I-solvent eguqukayo idinga ukuhwamuka ngezinga elifanele. AI-ramp ephezulunoma isilinganiso sangaphambi kokushisa singaholela ekwakhekeni kwe-solder balling. Ukuxazulula lokhu, qiniseka ukuthi i-ramp yakho-up ingaphansi kuka-1.5 ° C / sec kusuka ekushiseni kwegumbi eliphakathi kuya ku-150 ° C.

Ukususwa Kwebhola Lomthengisi

Fafaza ezinhlelweni zomoyayindlela engcono kakhulu yokususa ukungcoliswa kwebhola lomthengisi. Le mishini isebenzisa ama-nozzles aphezulu wengcindezelo esusa amabhola womthengisi empompi ebusweni bebhodi lokujikeleza eliphrintiwe ngenxa yokucindezela kwabo okunomthelela omkhulu.

Kodwa-ke, lolu hlobo lokususwa alusebenzi lapho impande ibangela iziqu ezivela ku-PCBS ezingekho emthethweni kanye nezingqinamba zangaphambi kokubonisa.

Ngenxa yalokhu, kungcono kakhulu ukuthola imbangela yamabhola we-soler ngokushesha ngangokunokwenzeka, njengoba lezi zinqubo zingathonya kabi ukukhiqiza kwe-PCB nokukhiqizwa kwakho. Ukuvimbela kuhlinzeka ngemiphumela emihle kakhulu.

Yeqa iziphambeko nge-ededeling inc

Lapho sibheka ngandlela thile, siyaqonda ukuthi okuhlangenwe nakho kuyindlela engcono kakhulu yokugwema ama-hiccups ahambisana ne-PCB Facrication kanye nomhlangano. Sinikeza ngekhwalithi esezingeni eliphezulu ethembelwe kwizicelo zezempi nezezempi, futhi zinikeze ukuguquguquka okusheshayo kokuPrototyping kanye nokukhiqizwa.
