Ukucolwa kweengcingo zobhedu kusetyenziswa kakhulu xa kuveliswa iingcingo, iintambo, kunye neengcingo ezenziwe nge-enameled. Ingubo ye-tin igqamile kwaye i-silvery emhlophe, enokunyusa i-weldability kunye nokuhlobisa ubhedu ngaphandle kokuchaphazela ukuhanjiswa kombane. Ingasetyenziswa kwishishini lombane, ifenitshala, ukupakishwa kokutya, njl. I-Anti-oxidation, yandisa ubuhle bezinto zokusebenza zobhedu. Akukho mfuneko yezixhobo ze-electroplating, kufuneka kuphela ukucwina, ukulungeleka kwaye kulula, kwaye inokugqithwa ngetoti eshinyeneyo. [1]

Intshayelelo yophawu
1. Ucingo lobhedu olunakiweyo lunokuthengiswa okugqwesileyo.

2. Njengoko ixesha litshintsha, i-solderability ihlala ilungile kwaye inokugcinwa ixesha elide.

3. Umphezulu ugudile, uqaqambile kwaye ufumile.

4. Ukusebenza okuzinzileyo nokuthembekileyo, ukuqinisekisa umgangatho ophezulu kunye nesivuno esiphezulu.

Iimpawu ezibonakalayo kunye neekhemikhali
1. Umxhuzulane okhethekileyo: 1.04 ~ 1.05

2. PH: 1.0~1.2

3. Imbonakalo: ulwelo olungenambala olucacileyo

inkqubo yokuhamba
Ukuchithwa kweendawo zobhedu - ukukhethwa okanye ukupholisa - ukuhlamba ezimbini - i-electroless tin plating - ukuhlamba okuthathu - okomileyo ngexesha kunye nomoya obandayo - uvavanyo.

I-Electroless tin plating: Yongeza i-8 ~ 10g/kg yezongezo zenkcenkce ezincancisayo kumanzi enkcenkce enkcankca phambi kokuba uyisebenzise. Ubushushu betoti yokuntywiliselwa bubushushu obuqhelekileyo ~ 80℃, kwaye ixesha lokuntywiliselwa kwitoti yimizuzu eyi-15. Ngexesha lenkqubo yokubeka i-tin, isisombululo sokucoca kufuneka sishukunyiswe ngobumnene okanye i-workpiece kufuneka iguqulwe ngobumnene. . Ukufunxwa okuphindaphindiweyo kunokunyusa ubukhulu be-tin layer.

Ukulumkela
I-workpiece yobhedu emva kwe-micro-etching kufuneka ifakwe kwisisombululo se-tin ngexesha emva kokuhlamba ukukhusela ubuso bobhedu ukuba buphinde bufakwe kwi-oxidized kwaye buchaphazele umgangatho wengubo.

Xa ukusebenza kwe-tinning kwehla, i-1.0% ye-tinning additive ingadityaniswa, kwaye ingasetyenziselwa emva kokuvuselela ngokulinganayo.
