History of otu kwadoro circuit board:

Mpempe akwụkwọ sekit nwere otu akụkụ bụ ngwaahịa mepụtara na United States na ọdịdị nke transistors na mbido afọ ndị 1950. N'oge ahụ, usoro etinyere ọla kọpa bụ ụzọ nrụpụta isi.

Na 1953-1955, Japan jiri mpempe ọla kọpa batara iji mepụta mpempe akwụkwọ ọla kọpa phenolic na nke mbụ ya, a na-ejikwa ya na redio.

Na 1956, mgbe ntoputa nke ọkachamara na-emepụta nke circuit mbadamba na Japan, n'ichepụta technology nke otu panel ozugbo mere ngwa ngwa.

Na usoro nke ihe, na mmalite ogbo, akwụkwọ phenolic ọla kọpa foil mkpụrụ bụ isi ihe. Otú ọ dị, n'ihi mkpuchi ọkụ eletrik dị ala, nkwụsi ike ikpo ọkụ na-ekpo ọkụ, ntụgharị na ihe ndị ọzọ nke ihe phenolic n'oge ahụ, a na-eji nwayọọ nwayọọ mepụta ihe ndị dị ka akwụkwọ resin gas resin na iko fiber epoxy resin. Ka ọ dị ugbu a, otu otu ndị ọrụ igwe elektrọnik chọrọ ka ọ were obere akwụkwọ resin.
