Xa kuthelekiswa nebhodi yesekethe enamacala amabini, ibhodi ye-pcb enamacala amabini inxinano ephezulu ye-wiring kunye ne-aperture encinci. , ezinje ngobutyobo bebrashi, uthuli lwentaba-mlilo, njalo njalo, xa sele ushiywe emngxunyeni ngaphakathi, uya kwenza ukuba ikhemikhali itshone ubhedu, ilahle ubhedu ngombane.

Ukuqinisekisa ukufezekiswa okuthembekileyo kwebhodi yesekethe enamacala amabini, umngxunya odityanisiweyo ebhodini kufuneka udityaniswe ngohlobo lwentambo kuqala, kwaye nenxalenye yokuncamathela kwencam yocingo kufuneka inqunyulwe, ukuze ungahliki isandla somqhubi. Lo ngumsebenzi wokulungiselela umgca wokudibanisa webhodi.

Ke, ziziphi iingxaki ekufuneka zinikwe ingqalelo kwi-pcb yebhodi yamacala amabini ye-welding?

1. Kwizixhobo ezifuna ukubumba, ziya kulandela iimfuno zenkqubo yokuzoba, ukubumba kuqala emva koko iplagi-kufakwe.

2. Emva kokubumba, uhlobo lwediode kufuneka lujongane phezulu, kwaye ubude bezikhonkwane ezibini akufuneki bungangqinelani.

3. Kwizixhobo ezineemfuno zokubonakala, kuya kuqatshelwa ukuba ukubola akusayi kufakwa kwicala elichaseneyo. Akukho kuthambeka ngokucacileyo kuya kuvunyelwa nkqo okanye ngokuthe tyaba kwizixhobo emva kokufakwa.

4. Amandla esinyithi sentsimbi yombane yi-25 ~ 40W, ubushushu bentloko yesinyithi yombane kufuneka ilawulwe kwi-242 ℃ okanye njalo, kwaye ixesha lokuwelda kufuneka lilawulwe kwimizuzwana emi-3 ~ 4.

I-5, ukuwelda ngokubanzi ngokwesixhobo ukusuka phezulu ukuya phezulu, ukusuka ngaphakathi ukuya ngaphandle komgaqo we-welding ukuze usebenze, ixesha lokuwelda enkosini, ixesha elide kakhulu liya kuba sisixhobo esishushu, liya kushushu ucingo olunxibe ilaphu lobhedu elityatye ipleyiti .

6, kuba i-welding emacaleni amabini, ngoko ke kufuneka yenze inkqubo yesakhelo ukubeka ibhodi yesekethe, injongo ayikokucofa isixhobo esingezantsi.

7. Emva kokugqitywa kwentsimbi, kuya kwenziwa uhlolo olubanzi lokujonga iindawo apho kukho khona ukuvuza kunye neentsimbi. Emva kokungqinisisa, nciphisa izikhonkwane ezingafunekiyo zesixhobo kwaye uzivumele zigeleze kwinkqubo elandelayo.

8. Umsebenzi othile uya kulandela ngokungqongqo imigangatho yenkqubo efanelekileyo ukuqinisekisa umgangatho we-welding.

Oku kungasentla amanyathelo okhuseleko ekusebenzeni kwebhodi ye-pcb yamacala amabini. Ukuba awuyazi, ungenza kubuzisa China ibhodi pcb umenzi - Yongmingsheng Circuit ibhodi Inkampani nangaliphi na ixesha.
