Aluminom substrate arụmọrụ

1.Excellent okpomọkụ dissipation arụmọrụ

Efere ọla kọpa nke dabeere na aluminom na-arụ ọrụ nke ọma na-ekpochapụ ọkụ, nke bụ akụkụ kachasị mma nke ụdị efere a. The PCB mere ya nwere ike ọ bụghị naanị n'ụzọ dị irè igbochi na-arụ ọrụ okpomọkụ nke components na substrates kwajuru na ya na-ebili, ma ngwa ngwa okpomọkụ eme site ike ampilifaya components, elu ike components, nnukwu sekit ike switches na ndị ọzọ components. A na-ekesakwa ya n'ihi obere njupụta ya, ịdị arọ dị arọ (2.7g / cm3), mgbochi oxidation, na ọnụ ahịa dị ọnụ ala, ya mere ọ ghọwo ihe kachasị mma na ọnụ ọgụgụ kasị ukwuu nke mpempe akwụkwọ na-emepụta ihe na ọla kọpa clad laminates. The juputara thermal eguzogide nke a gwara mmanụ aluminum substrate bụ 1.10 ℃ / W na thermal eguzogide bụ 2.8 ℃ / W, nke ukwuu mma fusing ugbu a nke ọla kọpa waya.

2.Mmelite arụmọrụ na mma nke machining

Ihe mkpuchi ọla kọpa nke dabeere na aluminom nwere ike ịrụ ọrụ dị elu na ike siri ike, nke dị mma karịa laminates ọla kọpa na-ekpuchi resin siri ike na ihe seramiiki. Ọ nwere ike na-aghọta imewe nke nnukwu-mpaghara e biri ebi mbadamba na metal substrates, na bụ karịsịa adabara arịọnụ arọ components na ndị dị otú ahụ substrates. Ke adianade do, aluminom mkpụrụ nwekwara ezi flatness, na ọ nwere ike kpọkọta na hazie na mkpụrụ site hammering, riveting, wdg ma ọ bụ ehulata na gbagọrọ agbagọ tinyere ndị na-abụghị wiring òkè na PCB mere ya, mgbe omenala resin- Ihe mkpuchi ọla kọpa dabeere na laminate enweghị ike .

1. Na-emebi mmanụ

A na-ekpuchi elu elu nke efere aluminom na akwa mmanụ n'oge nhazi na njem, na a ghaghị ihicha ya tupu ejiri ya. Ụkpụrụ bụ iji mmanụ ụgbọala (gasịnụ ụgbọ elu ụgbọelu) dị ka ihe mgbaze, nke nwere ike ịgbaze, wee jiri ihe na-ehicha mmiri na-edozi mmiri iji wepụ ntụpọ mmanụ.

3. Alkaline etching. Elu nke aluminom efere dị ka isi ihe kwesịrị inwe ụfọdụ roughness. Ebe ọ bụ na aluminom substrate na aluminum oxide film oyi akwa n'elu bụ ma amphoteric ihe, elu nke aluminom isi ihe nwere ike roughened site na iji acidic, alkaline ma ọ bụ mejupụtara alkaline ngwọta usoro. Na mgbakwunye, ihe ndị ọzọ na ihe mgbakwunye dị mkpa ka agbakwunyere na ngwọta roughening iji nweta ebumnuche ndị a.

4. Chemical polishing (dipping). N'ihi na ihe ndị dị na aluminom nwere ọla ndị ọzọ na-adịghị ọcha, ọ dị mfe ịmepụta ogige inorganic nke na-adabere na elu nke mkpụrụ ahụ n'oge usoro mgbagwoju anya, ya mere a ga-enyocha ogige ndị na-emepụta ihe na-emepụta n'elu. Dị ka nsonaazụ nyocha ahụ si dị, kwadebe ngwọta ntinye kwesịrị ekwesị, ma tinye ihe mgbochi aluminom na-edozi ahụ na ngwọta ntinye iji hụ na oge ụfọdụ, ka elu nke efere aluminom dị ọcha ma na-egbuke egbuke.
