1. Nkọwa nke Copper Clad Laminate?
Copper Clad Laminate, nke akpọrọ CCL, bụ ụdị ihe ndabere nke PCB.N'iji eriri iko ma ọ bụ akwụkwọ mpempe akwụkwọ osisi dị ka ihe na-agba ume, CCL bụ ụdị ngwaahịa site na lamination nke nwere ọla kọpa n'otu akụkụ ma ọ bụ n'akụkụ abụọ nke ihe na-agba ume mgbe etinyere ya na resin.
2. Nhazi nke CCLs?
Dịka ụkpụrụ nhazi ọkwa dị iche iche si dị, enwere ike kewaa CCL n'ụdị dị iche iche:
• Dabere na CCL igwe siri ike, E nwere CCL siri ike (FR-4, CEM-1, wdg) na Flex CCL.PCB siri ike na-adabere na CCL siri ike ebe PCB ndị na-emegharị emegharị nọ na CCL flex (PCB ndị siri ike dị na CCL siri ike na flex CCLs).
• Dabere na ihe mkpuchi mkpuchi na ihe owuwu, E nwere resin organic CCL (FR-4, CEM-3, wdg), metal-base CCL, seramiiki-base CCL wdg.
• Dabere na CCL thicknes E nwere ọkọlọtọ ọkpụrụkpụ CCL na mkpa CCL.Nke mbụ chọrọ opekata mpe 0.5mm ọkpụrụkpụ ebe nke ikpeazụ nwere ike ịdị gịrịgịrị karịa 0.5mm.Ewepụrụ ọkpụrụkpụ foil ọla kọpa na ọkpụrụkpụ CCL.
• Dabere n'ụdị ihe na-eme ka ọ dị ike, E nwere isi akwa akwa iko CCL (FR-4, FR-5), isi akwụkwọ CCL (XPC), CCL (CEM-1, CEM-3).
• Dabere na resin mkpuchi etinyere, E nwere epoxy resin CCL (FR-4, CEM-3) na Phenolic CCL (FR-1, XPC).
3. Kedu ụdị CCL a na-ejikarị eme ihe?
N'ime ngwaahịa CCL fiberglass, FR-4 CCL na-egwu iwu dị oke mkpa.A na-eji ya aṅụ n'ọtụtụ ebe n'ụdị mbadamba
Ruo ugbu a, a na-emepụta ngwaahịa dị iche iche dabere na FR-4 CCL ma mepụta ya n'ihi ọkwa arụmọrụ dị iche iche na edemede na-arụ ọrụ nke nta nke nta na mmepe.A na-egosipụta ngwaahịa ndị sitere na FR-4 CCL na nkịtị FR-4, Mid-Tg FR-4, High-Tg FR-4, Lead-free soldering FR-4, Halogen-free FR-4, Mid-Tg ( Tg150°C) halogen-free FR-4, High-Tg (Tg170°C) halogen-free FR-4,FR-4 CCL na elu arụmọrụ ect ..
Na mgbakwunye, e nwere High modulus FR-4 osisi, FR-4 osisi na ala ọnụọgụ nke thermal mgbasawanye, FR-4 osisi na ala dielectric mgbe nile, High-CTI FR-4 osisi, High-CAF FR-4 osisi, High thermal -conductivity FR-4 osisi maka LED.
Mgbe mgbalị na ahụmahụ na PCB n'ichepụta, PHILIFAST emewo egwuregwu dị mkpa iwu na-eme ka elu arụmọrụ na ngwá electronic n'ichepụta ụlọ ọrụ.
