Faʻafefea ona faʻavasega PCB PCB substrates?
Substrate, pei ona taʻu mai e le igoa, o le faavae, o le autu mea o gaosiga lolomi laupapa matagaluega, o le lautele PCB substrate e aofia ai resin, faʻamalosia mea, conductive mea, e tele ituaiga. Resin e sili ona taatele epoxy resin, phenolic resin, faamalosia mea e aofia ai le pepa, tioata ie, ma isi mea, o le sili ona masani ona faʻaaogaina mea mea o le tanoa foil, apamemea foil ua vaevaeina i electrolytic apamemea foil ma calendered apamila foil.
PCB substrate mea faʻavasegaina:
Tasi, e tusa ma le faʻamalosia mea:
1. Faʻavae pepa (FR-1, FR-2, FR-3);
2. Epoxy tioata alava tioata substrate (FR-4, FR-5);
3. Cm-1, CM-3 (Tuʻufaʻatasiga Epoxy Mea Vasega-3);
4.HDI (High Density Interconnet) laupepa (RCC);
Faʻapitoa substrate (uʻamea substrate, keramika substrate, thermoplastic substrate, ma isi).
