Kalasi Fnayiloni/ kusinthidwa polyester enameled kuzungulirawaya wamkuwa
Mafotokozedwe Akatundu
Mawaya okana awa a enameled akhala akugwiritsidwa ntchito mofala ngati zopinga wamba, magalimoto
mbali, mapiringidzo resistors, etc. ntchitokutsekerezakukonza koyenera kwambiri pakugwiritsa ntchito izi, kugwiritsa ntchito mwayi wodziwika bwino wa zokutira za enamel.
Kuphatikiza apo, timapanga zokutira za enamelkutsekerezawawaya wachitsulo wamtengo wapatali monga siliva ndi waya wa platinamu poyitanitsa. Chonde gwiritsani ntchito kupanga-pa-oda.
Mtundu wa waya wopanda Alloy
Aloyi titha kuchita enamelled ndi Copper-nickel aloyi waya, Constantan waya, Manganin waya. Kama Waya, NiCr Aloyi waya, FeCrAl Aloyi waya etc aloyi waya

Kugwiritsa ntchito Copper zojambulazo
1) Magetsi ndi magetsi, ma switch
2) Mafelemu otsogolera
3) Zolumikizira ndi mabango oscillation
3) PCB munda
4) Chingwe cholumikizirana, zida zankhondo, bolodi lalikulu lafoni
5) Kupanga batire ya ion ndi filimu ya PI
6) PCB wotolera (electrode backing) zipangizo
