Kodi zotsatira za solder resist color ku PCB ndi chiyani?

The PCB bolodi si zokongola kwambiri, zothandiza kwambiri.

Kwenikweni, mtundu wa bolodi la PCB ndi mtundu wa chigoba cha solder.Choyamba, kukana kwa solder kungalepheretse kusakaniza kolakwika kwa zigawozo.Chachiwiri, imatha kuchedwetsa moyo wautumiki wa zida, kuti ateteze makutidwe ndi okosijeni ndi dzimbiri la dera.

Ngati mukudziwa zambiri za PCB board ya HUAWEI, Ericsson ndi makampani ena akuluakulu, mupeza kuti mtunduwo umakhala wobiriwira.Chifukwa luso lobiriwira mtundu kwa bolodi PCB ndi okhwima kwambiri ndi yosavuta.

Kupatula wobiriwira, pali mitundu yambiri ya PCB, monga: yoyera, yachikasu, yofiira, yabuluu, yaying'ono kuwala, ngakhale chrysanthemum, wofiirira, wakuda, wobiriwira wobiriwira, etc. Choyera ndi pigment yofunikira yopanga nyali ndi nyali.Kugwiritsa ntchito mitundu ina makamaka ndi cholinga cholembera zinthu.PCB yopanga zinthu zamakampani kuchokera ku R&D mpaka kukhwima kwa siteji yonse, malinga ndi kugwiritsa ntchito kosiyanasiyana kwa bolodi la PCB, bolodi yoyeserera ikhoza kugwiritsa ntchito utoto wofiirira, bolodi lakiyi lidzagwiritsa ntchito zofiira, bolodi lamkati lamakompyuta lidzagwiritsa ntchito zakuda, zonse zomwe ndi kusiyanitsa ndi chizindikiro ndi mtundu.

PCB yodziwika kwambiri ndi bolodi yobiriwira, yomwe imadziwikanso kuti mafuta obiriwira, ndipo inki yake yotsutsa solder ili ndi mbiri yayitali kwambiri, yotsika mtengo komanso yotchuka kwambiri.Mafuta obiriwira ali ndi zabwino zambiri kuphatikiza ukadaulo wokhwima:

Pokonza PCB, kupanga zinthu zamagetsi kumaphatikizapo kupanga mbale ndi kupukuta.Panthawi imeneyi, pali njira zingapo zodutsa chipinda chowala chachikasu, ndipo bolodi la PCB lobiriwira limakhala ndi zotsatira zabwino kwambiri mu chipinda chowala chachikasu.Kachiwiri, mu SMT PCB board, masitepe a tinning, lamination ndi AOI verification zonse zimafunika mawonekedwe a kuwala ndi ma calibration, ndipo PCB yobiriwira ili bwino pakuzindikiritsa zida.

Gawo la ntchito yoyendera zimadalira momwe ogwira ntchito amawonera (tsopano ambiri amagwiritsa ntchito kuyesa singano m'malo mwa ntchito yamanja).Iwo amapitiriza kuyang'ana pa bolodi pansi pa kuwala kwamphamvu, ndipo kuwonongeka kwa zobiriwira kwa maso kumakhala kochepa.Gulu lobiriwira la PCB ndilokonda zachilengedwe, ndipo pambuyo pokonzanso kutentha, silingatulutse mpweya wapoizoni.

Mitundu ina ya PCB, monga buluu ndi yakuda imakhala ndi cobalt ndi kaboni motsatana.Chifukwa ndi ofooka conductive, pali chiopsezo yochepa dera.

Monga bolodi lakuda, ndilomwe limayambitsa kusiyana kwa mitundu chifukwa cha ndondomeko ndi zovuta zakuthupi zomwe zimapangidwira, zomwe zimatsogolera ku chilema chachikulu cha PCB.Mayendedwe a bolodi lakuda lakuda sikophweka kuzindikira, zomwe zidzawonjezera zovuta za kukonza ndi kukonza pambuyo pake.Chifukwa chake, ambiriOpanga msonkhano wa PCBsanagwiritse ntchito bolodi lakuda la PCB.Ngakhale m'munda wa makampani ankhondo ndi kulamulira mafakitale, mankhwala ndi zofunika mkulu khalidwe ntchito wobiriwira PCB bolodi.

Kodi zotsatira za solder kukana inki pa bolodi PCB ndi chiyani?

Pazinthu zomalizidwa, zotsatira za inki zosiyanasiyana pa bolodi zimawonekera makamaka pamawonekedwe.Mwachitsanzo, zobiriwira zimaphatikizapo zobiriwira za dzuwa, zobiriwira zobiriwira, zobiriwira zakuda, zobiriwira za matte ndi zina zotero.Ngati mtunduwo ndi wopepuka kwambiri, Pambuyo pa ndondomeko ya dzenje la pulagi, maonekedwe a bolodi adzakhala omveka.Opanga ena ali ndi inki yosauka, utomoni ndi vuto la chiŵerengero cha utoto, ndipo padzakhala thovu ndi mavuto ena Dziwani kusintha pang'ono kwa utoto.Kwa zinthu zomwe zatsirizidwa pang'ono, zotsatira zake zimawonekera makamaka pakuvuta kwa kupanga.Mafunso awa ndi ovuta kuwafotokozera.Mitundu yosiyanasiyana ya inki imakhala ndi mitundu yosiyanasiyana, kuphatikiza kupopera mbewu mankhwalawa ndi electrostatic, kupopera mbewu mankhwalawa ndi kusindikiza pazenera, ndipo chiŵerengero cha inki chimakhalanso chosiyana.Ngati pali cholakwika pang'ono, mtunduwo udzalakwika.

Ngakhale mtundu wa inki ulibe chikoka pa bolodi la PCB, makulidwe a inki amakhudza kwambiri kusokoneza.Makamaka pa bolodi la golide lamadzi, imayendetsa makulidwe a inki mosamalitsa.Inki yofiira, makulidwe ndi thovu ndizosavuta kuwongolera, ndipo inki yofiyira imatha kuphimba zolakwika zina padera, zomwe zimawoneka bwino, koma choyipa chake ndikuti mtengo wake ndi wokwera mtengo.Pojambula, zowonekera zofiira ndi zachikasu zimakhala zokhazikika, ndipo zoyera ndizoipitsitsa kwambiri.

Mwachidule, mtundu ulibe mphamvu pakugwira ntchito kwa bolodi yomalizidwa, ndipo umakhala ndi mphamvu zochepaChithunzi cha SMT PCBboard ndi maulalo ena.Mu PCB kapangidwe, mosamalitsa kulamulira mwatsatanetsatane aliyense ulalo ndi kiyi wabwino PCB bolodi.Mitundu yosiyanasiyana ya bolodi la PCB, makamaka mawonekedwe abwino a mankhwalawa, sitikulangiza mtundu ngati chinthu chofunikira pakukonza PCB.
