Ucingo lobhedu lusetyenziswa kakhulu kwimveliso yeengcingo, iintambo, kunye neengcingo ze-ensimes. I-tin ihlazo iqaqambile kwaye i-Silfey Short, enokwandisa impindezelo kunye nokuhonjiswa kobhedu ngaphandle kokuchaphazela ukuqhubela phambili kombane. Ingasetyenziswa kumzi-mveliso we-elektroniki, ifenitshala, ukupakishwa kokutya, njl njl. Akukho sidingo sokufaka izixhobo zombane, kufuneka kuphela ukuba i-toak, ilula kwaye ilula, kwaye inokuthi ifakwe nge-tick tin. [1]

Intshayelelo
I-1. Ucingo lobhedu olunobhedu lube nokurhwelela kakubi.

2. Njengoko ixesha litshintsha, ukungathathi ntweni kuhlala kulungile kwaye kungagcinwa ixesha elide.

3. Umphezulu ugudileyo, qaqambile kwaye unomswakama.

4. Umsebenzi ozinzileyo nothembekileyo, uqinisekisa umgangatho ophezulu kunye nesivuno esikhulu.

Izalathisi zomzimba kunye neekomamikhali
I-1. Ubuninzi obuthile: 1.04 ~ 1.05

2. PH: 1.0 ~ 1.2

I-3. Imbonakalo

Inkqubo yokuhamba
Ukukhupha iinxalenye zobhedu-Ukuthathwa okanye ukuhlanjwa ezimbini - i-tin ye-elektroniki ye-elektroniki - ukuhlanjwa ezintathu-zomile ngexesha lovavanyo olubandayo lomoya.

I-Longroftronce Taptha: Yongeza i-8 ~ 10g / kg ye-tin idrotiments kwi-tin ibeka amanzi ngaphambi kokusetyenziswa. Iqondo lobushushu le-tin lineqondo eliqhelekileyo le-80 ℃, kunye nexesha lokuntywila nge-tin yimizuzu eli-15. Ngexesha lenkqubo yokubekwa kwe-tin, isisombululo sokubetha kufuneka sishukunyiswe ngobunono okanye umsebenzi osebenzayo kufuneka ujike ngobunono. . Ukuhamba okuphindiweyo kunokunyusa ubukhulu be-tin.

Ukulumkela
I-CopperPiece yokusebenza emva kokuba i-white-etching kufuneka ifakwe kwisisombululo se-tin seltating ngexesha emva kokuhlamba ukunqanda umphezulu wobhedu ukuba iphinde ichaphazele umgangatho wokuphathwa.

Xa i-tinning yokusebenza kwehla, i-1.0% ye-tinning inokongezwa, kwaye inokusetyenziswa emva kokuvuselela ngokulinganayo.
