Letlapa lena la likonopo le entsoe ka foreimi ea li-keypad tsa ABS le likonopo tsa alloy tsa zinki ho fokotsa litšenyehelo tse ling ho tsoa ho thepa ea foreimi, empa e ntse e ka khona ho fihlela ts'ebetso ha e e sebelisa.
Joalo ka ha ho ka ba le ntlo e sirelletsang kantle ho letlapa la likonopo, boemo ba bopaki ba vandal bo ntse bo tšoana le keypad e felletseng ea tšepe.Mabapi le PCB, re sebelisitse ho roala ha proforma ka mahlakoreng ka bobeli ho fihlela mesebetsi e sa keneleng metsi, lerōle le mesebetsi e khahlanong le static.
1. Thepa ea li-keypad e entsoe ka thepa ea ABS e nang le likarolo tsa bopaki ba vandal le likonopo li entsoe ka lisebelisoa tsa alloy tsa zinc tse nang le anti corrosion chrome surface plating.
2.The conductive rabara e entsoe ka rabara ea tlhaho e nang le carbon layer, e nang le ts'ebetso e ntle ha e ama monoana oa khauta ho PCB.
3.The PCB e entsoe ka litsela tse peli tse lehlakoreng tse ka tšeptjoang haholoanyane ha likarolo tsa tšepe tse amang 'me PCB e na le ho roala ha proforma ka mahlakoreng ka bobeli.
