1.HDI farantin kayan RCC, LDPE, FR4
RCC: short for Guduro mai rufi jan karfe, guduro mai rufi foil, RCC hada da jan karfe foil da guduro wanda surface ya roughened, zafi jure, hadawan abu da iskar shaka-resistant, da dai sauransu, da kuma tsarin da aka nuna a cikin adadi a kasa: (amfani da shi. lokacin da kauri ya wuce 4mil)
Ramin guduro na RCC yana da aiki iri ɗaya da FR-1/4 bonded sheets (Prepreg). Baya ga biyan buƙatun aikin da suka dace na hukumar multilayer na hanyar tarawa, kamar:
(1) Babban amincin rufi da amincin ramin micro-conducting;
(2) Babban zafin canjin gilashin (Tg);
(3) Low dielectric akai-akai da ƙananan sha ruwa;
(4) Babban mannewa da ƙarfi ga foil na jan karfe;
(5) Uniform kauri na rufi Layer bayan warkewa.
A lokaci guda, saboda RCC sabon nau'in samfuri ne ba tare da fiber gilashi ba, yana da kyau don etching ramin jiyya ta hanyar Laser da plasma, wanda ke da kyau ga nauyi mai sauƙi da ɓarke na allon multilayer.
