Ukongeza kwi-wiring kwi-substrate, i-coating yensimbi yilapho iingcingo ze-substrate zixutywe kwizinto ze-elektroniki.
amaxabiso, ezahlukeneyo ziya kuchaphazela ngqo iindleko imveliso;Iintsimbi ezahlukeneyo kwakhona weldability ezahlukeneyo, zoqhagamshelwano, kunye namaxabiso ukumelana, nto leyo eya kuchaphazela ngqo ukusebenza amacandelo.

Iingubo zentsimbi eziqhelekileyo zezi:
Ubhedu
Inkcenkce

Ubukhulu buqhele ukuba phakathi kwe-5 kunye ne-15 cm ye-Lead-tin alloy (okanye i-tin-copper alloy).
Oko kukuthi, i-solder, ngokuqhelekileyo i-5 ukuya kwi-25 m ubukhulu, kunye nomxholo we-tin malunga ne-63%.

igolide; Ngokubanzi iya kucakwa kuphela kujongano.

isilivere; Ngokubanzi iya kucandwa kuphela kujongano, okanye iyonke ikwayialloyi yesilivere.
