What is the processing technology of DPC ceramics for double-sided and single-sided aluminum substrates

Word:[Big][Middle][Small] QR Code 2020-5-31     Viewed:    
  Aluminum substrate is mostly used in LED industry,single-sided double-layer aluminum substrate or only one side can stick led,single-sided wiring;double-sided aluminum substrate is able to stick led on both sides,double-sided aluminum substrate must be double-layer wiring.So what is the actual difference between the processing technology of single-sided aluminum substrate and double-sided aluminum substrate?

  Double sided aluminum substrate

  1:Compared with single-sided aluminum plate,double-sided aluminum plate has one more pressing process!But the price difference is very big,the production process is very difficult!

  2、Why to drill two holes on double-sided aluminum base plate

  Because it is not easy to inlay copper on the aluminum surface immediately,it is necessary to drill through the aluminum alloy plate first and cover the aluminum surface with epoxy resin.

  The specific steps are as follows:

  The first drilling of aluminum base-->pressing(filling the hole with epoxy resin)-->the second drilling(internal cutting circle)-->electroplating process

  3、Differences in manufacturing steps

  Single sided aluminum base plate:before aluminum alloy plate is made,it is aluminum base plate after widening heat transfer cable sheath and copper berthing and high-temperature and strong pressure forming.Double sided aluminum base plate:after aluminum alloy plate is machined,it is solved before it is made,and after hole insulation layer,double-sided high heat transfer cable sheath,double-sided copper berthing and high-temperature and strong pressure forming,it is double-sided aluminum base plate after mechanical processing,pattern transfer and machine forming;{finished products}more solid wood Laminate:after the transfer of the pattern,the lamination and the transition of the pattern.The production and processing of the{double layer route}solid wood multilayer board depends on the product variety and the production and processing regulations
