Pakali pano, pali mitundu iwiri ya PCB gulu m'mphepete kamangidwe: metallization ndi sanali metallization. Pakuti sanali metallization, opanga makampani okhwima, koma teknoloji metallization akadali mwana. Masiku ano, zosowa zopanga makasitomala ambiri zikutembenukira ku PCB zitsulo edging . Choncho, khalidwe la PCB zitsulo edging wakhala cholinga cha chidwi makasitomala 'ndi opanga chifukwa khalidwe lake mwachindunji zimakhudza ntchito mankhwala.

 Kodi kugwiritsa ntchito m'mphepete mwa PCB ndi chiyani?

Ma board ozungulira am'mphepete amapezeka m'mafakitale ambiri, ndipo plating m'mphepete ndi mchitidwe wamba. Mupeza PCB m'mphepete castelation (kapena m'mphepete plating PCBs) ntchito nthawi zambiri, kuphatikizapo:

· Kupititsa patsogolo luso lonyamula katundu

· Kulumikizana m'mphepete ndi chitetezo

· Kuwotchera m'mphepete kuti muwonjezere kupanga

Thandizo labwino la zolumikizira monga matabwa omwe amatsetsereka muzitsulo zazitsulo

Kodi njira ya PCB m'mphepete plating ndi chiyani?

Monga mukudziwira, pali zovuta zambiri kwa opanga ma PCB amitundu yambiri makamaka momwe angakonzekerere m'mphepete mwake ndikumatira kwautali wazinthu zopukutidwa, kuwonjezera apo, pamafunika kuwongolera mwatsatanetsatane mukupanga PCB yomwe imagwiritsidwa ntchito m'mphepete. Kusintha kwa PCB. Tikhoza kuonetsetsa kuti PCB m'mphepete castellation bwino amakonzekera m'mbali kalikonse, yomwe imagwiritsa ntchito mkuwa wokutidwa kuti agwirizane mwamsanga ndi ndondomeko bolodi dera kuonetsetsa kuti nthawi yaitali adhesion pakati wosanjikiza aliyense.

Mosafunikira kunena, titha kuwongolera chiwopsezo chomwe chingakhale chokutidwa ndi dzenje ndi m'mphepete mwazitsulo ndi ndondomeko yoyendetsedwa panthawi yosindikizira ma boardboard kupanga m'mphepete mwa soldering. Chifukwa chake chodetsa nkhawa kwambiri ndi kupanga ma burrs, omwe amabweretsa discontinuities kukutidwa ndi makoma a dzenje ndikuchepetsa moyo womamatira wa m'mphepete mwake.

Ma contour akunja, kuti akhale opangidwa ndi zitsulo, amayenera kuphikidwa asanabowole, popeza zitsulo za m'mphepete zimachitika panthawiyi. Pambuyo pakuyika kwa mkuwa, kumalizidwa kwapamwamba kumagwiritsidwa ntchito m'mphepete.

Mavuto Opanga:

1. Copper Peeling -Kuyika pamwamba pa gawo lalikulu la gawo lapansi kungayambitse kupukuta kwa mkuwa chifukwa cha kusowa kwa mphamvu zomatira. Timathana ndi izi poyamba kukwiyitsa pamwamba pophatikiza mankhwala ndi njira zina zogwirizira. Kenako, timagwiritsa ntchito zitsulo zolunjika, zomwe zimakhala ndi mphamvu zomangira zamkuwa, kuti zikonzere pansi kuti zisamangidwe.

2. Burrs -Nthawi zambiri kuyika m'mphepete, makamaka pamabowo a castellation, kungayambitse ma burrs kuchokera kumachitidwe omaliza a makina. Timagwiritsa ntchito njira zosinthidwa, zomwe zimapangitsa kuti ma burrs apukutidwe mpaka m'mphepete mwa mawonekedwewo.

Chidziwitso cha Fab:

1. Malo a mlongoti wa padi ya golide ndiakulu kwambiri, zomwe zimakhudza kugulitsa kwamakasitomala kapena kutumiza ma siginecha.

2. Mphepete mwa m'mphepete mwake imagwirizanitsidwa ndi mawaya pa bolodi, zomwe zimapangitsa kuti pakhale nthawi yochepa.

3. Bowo la sitampu limapangidwira polowera ndipo liyenera kugwiridwa pobowola 2.

4. Kupyolera mu ndondomeko zokhudzana kupanga PCBs munthu monga gulu, mosalekeza metallization wa m'mbali akunja sizingatheke. Palibe metallization yomwe ingagwiritsidwe ntchito pomwe milatho yaying'ono imakhala.

5. Pempho limodzi, slide plating metallization ikhoza kuphimbidwa ndi chigoba cha solder.

Mukamagula matabwa a m'mphepete mwake, muyenera kutsimikizira ndi wopereka wanu PCB kuthekera kopanga ma PCB okhala ndi njira zopukutira, komanso momwe wopanga angapangire m'mphepete mwa mbale PCB. Mafayilo anu a Gerber kapena zojambulazo zikuyenera kuwonetsa pamakina osanjikiza pomwe amafunikira plating, ndi kumaliza kwake komwe amafunikira. Opanga ambiri amakonda kusankha ENIG ngati chomaliza chokhacho chomwe chili choyenera kuzungulira ma castellation.

YMS Electronics Co., Ltd. ndi akatswiri opanga matabwa apamwamba olondola kwambiri, ma module omiza golide, matabwa ozungulira magalimoto, zojambulira, zida zamagetsi za COB, mavabodi apakompyuta, matabwa ozungulira azachipatala, matabwa omangira ma module, board, thermoelectric separation copper substrate, etc. RayMing amapereka chitsimikizo chapamwamba chapamwamba komanso kutumiza nthawi, bizinesi yapamwamba yogulitsa malonda onse. Ngati pali kufunikira kwa matabwa a golide okutidwa m'mbali, chonde omasuka kutilumikizani!
