Njira Yopangira Aluminium PCB

Njira Yopangira Aluminiyamu PCB Njira yopangira aluminium PCB yokhala ndi mapeto a OSP: Kudula→ Kubowola → Dera → Etching ya Acid/alkaline→ Solder Mask→ Silkscreen→V-cut→PCB Test→OSP→FQC→FQA→Kupaka→Kutumiza.

Njira yopangira aluminiyamu PCB yokhala ndi zomaliza za HASL: Kudula → Kubowola → Circuit→ Acid/alkaline etching→ Solder Mask→Silkscreen→HASL→V-cut→PCB Test→FQC→FQA→Packing→Kutumiza.

YMSPCB angapereke zotayidwa pachimake PCB ndi chimodzimodzi pamwamba mapeto ndondomeko monga FR-4 PCB: Kumiza Gold / woonda / siliva, OSP, etc.

Popanga aluminium PCB, gawo lochepa la dielectric limawonjezeredwa pakati pa gawo lozungulira ndi gawo loyambira. Dielectric wosanjikiza wotere ndi wotsekera pamagetsi, komanso amayendetsa thermally. Pambuyo powonjezera gawo la dielectric, gawo lozungulira kapena zojambulazo zamkuwa zimakhazikika

Zindikirani

1. Ikani matabwa muzenera-shelefu kapena kuwalekanitsa ndi mapepala kapena mapepala apulasitiki kuti apewe zokopa panthawi yoyendetsa kupanga.

2. Kugwiritsa ntchito mpeni kukanda wosanjikiza insulated mu njira iliyonse sikuloledwa panthawi yonse yopanga.

3. Kwa matabwa osiyidwa, zoyambira sizingabowoledwe koma zimangolembedwa "X" ndi cholembera chamafuta.

4. Kuyang'ana kwachiwonetsero chonse ndikofunikira chifukwa palibe njira yothetsera vuto lachitsanzo pambuyo pa etching.

5. Chitani macheke a 100% a IQC pama board onse ogulitsa zinthu molingana ndi zomwe kampani yathu imayendera.

6. Sonkhanitsani matabwa onse opanda vuto palimodzi (monga dim color & scratch of AI surface) kuti akonzenso.

7. Vuto lililonse panthawi yopanga liyenera kudziwitsidwa kwa ogwira ntchito zaukadaulo munthawi yoyenera kuthetsedwa.

8. Njira zonse ziyenera kuyendetsedwa motsatira zofunikira.

Aluminiyamu osindikizidwa ma circuit board amadziwikanso kuti ma PCBs azitsulo ndipo amakhala ndi zitsulo zopangidwa ndi zitsulo zomwe zimakutidwa ndi zigawo zamkuwa. Amapangidwa ndi mbale za alloy zomwe zimakhala ndi aluminium, magnesium ndi silumin (Al-Mg-Si). Aluminiyamu PCBs amapereka kwambiri kutchinjiriza magetsi, zabwino matenthedwe kuthekera ndi mkulu Machining ntchito, ndipo amasiyana PCBs ena m'njira zingapo zofunika.

Zigawo za Aluminium PCB

 

BASE LAYER

Chigawochi chimakhala ndi gawo lapansi la aluminium alloy. Kugwiritsa ntchito aluminiyumu kumapangitsa PCB yamtunduwu kukhala chisankho chabwino kwambiri paukadaulo wapabowo, womwe tidzakambirane pambuyo pake.

NTCHITO YA THERMAL INSUlation

Chigawo ichi ndi gawo lofunika kwambiri la PCB. Ili ndi polima ya ceramic yomwe ili ndi mawonekedwe abwino kwambiri a viscoelastic, kukana kwambiri kutentha ndikuteteza PCB kupsinjika kwamakina ndi kutentha.

MALO Ozungulira

Chigawo chozungulira chimakhala ndi zojambula zamkuwa zomwe tazitchula kale. Nthawi zambiri, opanga PCB amagwiritsa ntchito zojambula zamkuwa kuyambira ma ola limodzi mpaka 10.

DIELECTRIC LAYER

Dielectric wosanjikiza wa insulation imatenga kutentha pamene pano ikuyenda mu mabwalo. Izi zimasamutsidwa ku aluminiyumu wosanjikiza, kumene kutentha kumamwazikana.

Kupeza kuwala kwapamwamba kwambiri kumabweretsa kutentha kwakukulu. Ma PCB okhala ndi kukana kwabwino kwamafuta amakulitsa moyo wazinthu zomwe mwamaliza. Wopanga woyenerera adzakupatsani chitetezo chapamwamba, kuchepetsa kutentha ndi kudalirika kwa gawo. Ku YMS PCB, timadzidalira pamiyezo yapamwamba kwambiri komanso mtundu wantchito zomwe mukufuna.
