Akụkọ mmepe nke PCB Board

Ebe ọ bụ na a mụrụPCB osisi, o tolitela ihe karịrị afọ iri asaa.N'ime usoro mmepe nke ihe karịrị afọ 70, PCB enweela mgbanwe dị mkpa, nke kwalitere ngwa ngwa mmepe nke PCB ma mee ka ọ bụrụ ngwa ngwa etinyere na mpaghara dị iche iche.N'ime akụkọ mmepe nke PCB, enwere ike kewaa ya na oge isii.

(1) Ụbọchị ọmụmụ PCB.A mụrụ PCB site na 1936 ruo na njedebe 1940.Na 1903, Albert Hanson buru ụzọ jiri echiche nke "akara" tinye ya na usoro mgbanwe ekwentị.Echiche nke echiche nke a bụ igbutu obere ígwè foil n'ime ndị na-eduzi sekit, wee dụkọta ha na mpempe akwụkwọ paraffin, ma mechaa mado oyi akwa nke akwụkwọ paraffin n'elu ha, si otú a na-akpụpụta ihe nhazi nke PCB nke oge a.Na 1936, Dr. Paul Eisner chepụtara n'ezie mmepụta teknụzụ nke PCB.A na-ewerekarị oge a dị ka ezigbo oge ọmụmụ PCB.N'ime oge akụkọ ihe mere eme a, usoro nrụpụta anabatara maka PCB bụ usoro mkpuchi, usoro ịgbasa, usoro ntinye oghere, usoro evaporation, usoro ntinye kemịkalụ na usoro mkpuchi.N'oge ahụ, a na-ejikarị PCB eme ihe na ndị na-anata redio.

(2) Oge mmepụta oge nke PCB.Oge mmepụta ule PCB bụ na 1950s.Site na mmepe nke PCB, ebe ọ bụ na 1953, ụlọ ọrụ na-emepụta ngwá ọrụ nkwurịta okwu malitere itinyekwu uche na PCB wee malite iji PCB n'ọtụtụ buru ibu.N'ime oge akụkọ ihe mere eme a, usoro nrụpụta nke PCB bụ usoro mwepu.Usoro a kapịrị ọnụ bụ iji ọla kọpa kpuchiri mpempe akwụkwọ phenolic resin laminate (ihe PP), wee jiri kemịkalụ gbarie foil ọla kọpa na-achọghị, nke mere na foil ọla kọpa fọdụrụ na-etolite sekit.N'oge a, ihe mejupụtara kemịkalụ nke ngwọta corrosive ejiri maka PCB bụ ferric chloride.Ngwaahịa a na-anọchite anya ya bụ redio transistor nwere ike ibugharị nke Sony rụpụtara, nke bụ PCB nwere otu oyi akwa nwere mkpụrụ PP.

(3) Ndụ bara uru nke PCB.Ejiri PCB rụọ ọrụ na 1960.Ebe ọ bụ na 1960, ụlọ ọrụ ndị Japan malitere iji GE base material (obere akwa akwa akwa epoxy resin laminate) n'ọtụtụ.N'afọ 1964, ụlọ ọrụ sekit anya nke America mepụtara ngwọta ọla kọpa na-enweghị ọla kọpa (cc-4) maka ọla kọpa dị arọ, si otú a malite usoro mmepụta usoro mgbakwunye ọhụrụ.Hitachi webatara teknụzụ cc-4 iji dozie nsogbu nke nrụrụ ọkụ na-ekpo ọkụ na ikpochapụ ọla kọpa nke ụlọ Ge na mbido mbụ.Site na nkwalite mbụ nke teknụzụ ihe onwunwe, ịdịmma Ge base ihe na-aga n'ihu na-abawanye.Ebe ọ bụ na 1965, ụfọdụ ndị na-emepụta malitere ịmepụta ihe ndị dị na Ge substrates, Ge substrates maka ngwá electronic ụlọ ọrụ mmepụta ihe na PP substrates maka ngwá electronic obodo na Japan.
