Tsigira Ukobvu | 25.4µm kusvika 50.8µm | 2.54µm kusvika 25.4µm |
Surface Cost | Yakachipa kupfuura ENIG, inodhura pane yakakosha HASL | Mutengo wepakati kana uchienzaniswa nemamwe |
chengetedzo | Iine lead, inokuvadza kune hutano / zvisikwa | Yakachengeteka, hapana lead inoshandiswa |
Kune maindasitiri akaomarara, HASL isina mutobvu inoshanda zvakanyanya. Kune mapurojekiti akachipa, HASL ine mutobvu yakanaka. Ita kuti sarudzo yako ienderane nezvaunoda, bhajeti, nemitemo.
