Hard Gold PCB: kuphatikiza Thupi Lathunthu ndi Kusankha Mwakhama Golide Wotsika Golide Womaliza
, yemwe amadziwikanso kuti Hard Electrolytic Gold, amapangidwa ndi golide wosanjikiza ndi zowonjezera zowonjezera zowonjezera, zokutidwa ndi chovala chotchinga cha nickel pogwiritsa ntchito njira yamagetsi . Golide wolimba ndi wolimba kwambiri, ndiye kuti pakapangidwe ka PCB pamapeto pake amagwiritsidwa ntchito m'malo okhala ndi zotchipa kwambiri, monga cholumikizira m'mphepete chagolide Zala ndi keypads, popeza kuuma kwa kumaliza kumatha kupirira kugwiritsidwa ntchito mobwerezabwereza; komabe, chifukwa chokwera mtengo kwa golide wolimba, komanso kuthekera kwake kosavomerezeka, sichimagwiritsidwa ntchito kwambiri kumadera osungunuka.
Thupi Lonse Lolimba Golide nthawi zambiri limakhala losankhidwa pafupipafupi, pomwe thupi lonse la PCB limakutidwa ndi golide wolimba. Pofuna kuyika mathero athunthu a Thupi Lolimba Golide, njira yamagetsi yogwiritsira ntchito magetsi kapena njira yomiza imafunika, kutengera kapangidwe ka PCB. Ntchito Complete PCB Assembly, kumene ife yonama ndi kusonkhanitsa matabwa, ifenso tiyenera kuganizira solderability osauka a chitsiriziro ichi; kamwazi yogwira kwambiri idzafunika kuthetsera bwino padi yolimba-golide
