Fr-4 zvinhu, iyo ipfupi yeiyo fiberglass machira, iyo Subiti kutaurwa. Zvinonyanya kushandiswa muPCB Nekuda kwesimba rayo rakakwirira uye rakaremara restardency, Fr-4 rinosarudzwa seyakagadziriswa zvinyorwa zvemabhodhi ematunhu mazhinji.
Zvakanakira Fr-4 uye & hunhu.
Chaizvoizvo, sident sident uye multilayer pcb wedunhu redunhu rinogadzirwa kubva kuFr-4 Drever Flame Retarland kunge pepa rakatetepa rakarukwa. Izwi rekuti Fr-4 zvakare inomirira giredhi raishandiswa kuita aya laminates. Iyo fergerglass kuvaka inopa kugadzikana kwechimiro kune izvo zvinyorwa. Iyo fiberglass layer yakafukidzwa nemurazvo unodzoreredza epoxy resin. Izvi zvinounza kusimba uye kwakasimba michina kune izvo zvinhu. Zvivakwa zvese izvi zvinoita kuti FR-4 akadhindwa wedunhu mabhoti anozivikanwa pakati pevakagadziri vechibvumirano chemagetsi.
Maitiro ayo ehunyanzvi anonyarara mu: maitiro akagadzikana, kubata zvakanaka, kwakaringana kuita mabhodhi emisangano, yakadai. Potsiometer Carbon firimu yakadhindwa fiberglass mabhodhi, precision vernier maGears zvichingodaro.
Pepa rapfuura rave kushandiswa zvakanyanya muchiuto, makomputa, makomputa, zviridzwa zveDhijitari, zviridzwa zvezvigadzirwa zvemotokari uye zvimwe zvigadzirwa zvemagetsi, zviratidzo zvezvigadzirwa zvemagetsi zvinokonzeresa zvigadzirwa zvemaindasitiri zvemaindasitiri. Kune mutengo wakanaka kwazvo-mashandiro echitambi.
