Zoyambitsa ndi njira zothetsera redness wa PCB dera bolodi solder chigoba chophimba kusindikiza

The PCB dera bolodi makampani wakhala ali ndi zofunika okhwima khalidwe ndondomeko kupanga.Pakati pawo, redness wa bolodi PCB dera chifukwa solder chigoba chophimba kusindikiza ndi wamba osafunika chodabwitsa.Sizimangokhudza zokongola zakunja za PCB, komanso zimakhudza gulu ladera.Palinso zoopsa zabwino muzochita.Nkhaniyi - pcb Zida Network adzatsogolera inu kumvetsa mozama zifukwa ndi njira zothetsera redness wa bolodi PCB chifukwa solder chigoba chophimba kusindikiza pa bolodi PCB dera.

1. Chifukwa PCB dera bolodi solder chigoba chophimba kusindikiza zimayambitsa redness pa bolodi pamwamba

1. Makulidwe a chigoba cha solder sichokwanira kapena pali thovu lotsalira:

Chigoba cha solder chimatanthawuza gawo la chitetezo chotchinga pa bolodi la dera pambuyo posindikiza ndi inki solder mask chophimba kuteteza dera kuti lisakhudzidwe ndi zinthu monga chilengedwe chakunja;pamene makulidwe a solder chigoba wosanjikiza si mpaka muyezo kapena pali thovu zotsalira, m`pofunika kuti Panthawi imeneyi, makutidwe ndi okosijeni zimachitikira sachedwa kuchitika pamene akukumana ndi kutentha kwambiri chilengedwe, kumabweretsa redness pamwamba pa bolodi, kuchititsa osauka. Ubwino wa PCB.

1. Ubwino wa inki siwoyenera:

Ngati inki yomwe imagwiritsidwa ntchito posindikizira chigoba cha solder ili ndi zovuta zabwino, monga inki yomwe yatha komanso kuchuluka kwa kukhuthala kwa inki, kungayambitse kulephera kwa chigoba cha solder, kapena sikungathe kuphimba dera lonselo, kusiya mipata ndi zina. zopinga zabwino, zomwe zimatsogolera kuzinthu zosafunikira monga kufiira pa bolodi zitha kubweretsa zoopsa zomwe sizikudziwika komanso kukhudza kwake momwe zimagwirira ntchito komanso mtundu wake.

 3. Inki ya flux ndi solder mask sizikufanana:

 Makhalidwe olakwika a matabwa a PCB osindikizidwa nthawi zambiri amapezeka pogwirizanitsa kapena njira zoyandikana nazo.Mwachitsanzo, flux ndi solder kukana inki sagwirizana kapena sagwirizana, zomwe zingayambitsenso mikangano, kusintha kwa katundu, ndi zina zotero, zomwe zimabweretsa kufiira kwa bolodi.

2. Kuthetsa njira PCB dera bolodi solder chigoba chophimba kusindikiza kuchititsa redness pa bolodi pamwamba

 1.PCB dera bolodi solder chigoba chophimba kusindikiza-chisanadze kupanga specifications kukhathamiritsa:

 Solder chigoba inki kusankha, inki mamasukidwe kusinthasintha modulation, inki alumali moyo alumali, flux ndi zina consumables zogwirizana muyezo kasamalidwe ndi ntchito mfundo, kupanga magawo ndi masitepe kupewa PCB chilema ngozi chifukwa cha zipangizo.

 2.PCB dera bolodi solder chigoba chophimba kusindikiza-mu-kupanga ndondomeko kukhathamiritsa:

 Makina osindikizira a PCB board board amafotokoza mosalekeza mwachidule ndikuchotsa zolakwika ndikusintha masinthidwe okhazikika potengera zofunikira zosindikiza kuti zitsimikizire kuchuluka kwasayansi komanso koyenera, potero kuwonetsetsa kuti kupanga kosasunthika komanso kokhazikika.

 3.PCB dera bolodi solder chigoba chophimba kusindikiza-post-kupanga khalidwe kuyendera kukhathamiritsa:

 Konzani njira zowunikira zowunikira kuti muwonetsetse kuti mavuto apezeka munthawi yake kuti apewe kuwonjezereka kwa zotayika komanso kuchepetsa kukhudzidwa kwa kupanga.

 4.PCB dera bolodi solder chigoba chophimba kusindikiza-wantchito kupanga maphunziro:

 Kupititsa patsogolo luso la ogwira ntchito kuti azindikire, kuzindikira, kusanthula ndi kuthetsa mavuto amtundu wa ndondomeko, kupititsa patsogolo luso la akatswiri ndi kumvetsetsa mfundo za mavuto oyipa, kuwunika nthawi zonse ndi maphunziro, ndikupanga ndondomeko zoyendetsera ntchito kuti antchito athe kugwira ntchito moyenera komanso molondola, ndikuyankha. kuthetsa ndi kuthetsa mavuto osiyanasiyana munthawi yake.vuto ladzidzidzi.

3. PCB dera bolodi solder chigoba chophimba kusindikiza kumapangitsa gulu pamwamba kukhala wofiira.Zoyenera kuchita mwachidule

 Vuto PCB dera bolodi solder chigoba chophimba kusindikiza bolodi redness ndi vuto wamba mu ndondomeko kupanga, koma si vuto zovuta.Nthawi zambiri zimakhala zazing'ono komanso poyambira, ndipo ndizosavuta kuchitika m'mafakitale osaphunzitsidwa bwino komanso okhazikika.Kuti athetse vutoli, cholinga ayenera kupangidwa Professional ndi standardized opaleshoni njira, kusankha yoyenera PCB dera bolodi solder chigoba chophimba makina makina osindikizira ndi oyendetsa akatswiri kupewa kuchitika kwa zolakwa otsika, zomwe zingakhudze khalidwe la kampani ndi mabuku. phindu.
