Qhov txawv ntawm Matte tin thiab Bright tin
Tag nrho cov tin plating feem ntau muab faib ua "Matte tin" thiab "Bright tin", fuse kawg caps feem ntau plated nrog matte tin. Dab tsi yog qhov txawv ntawm Matte tin thiab Bright tin?
| Title | Matte tin | Ci tin |
| Solderability | Zoo | Tsis zoo thiab nquag tin whiskers (vim tias cov organic impurities yuav ua rau compressive kev nyuaj siab thiab tsim tin whiskers) |
| Kev ntseeg tau | Relatively ruaj khov thiab tsis yooj yim los tsim tin whiskers | Nws yog ib qho yooj yim kom loj hlob tin whiskers tom qab khaws cia ntev, ua rau luv luv |
| Plating qhov txawv | Plating crystal particle yog ntxhib | Brightening tus neeg sawv cev yuav muab ntxiv los ua kom cov khoom siv lead ua ntawm cov txheej txheej nyias nyias thiab ci, tab sis tus neeg sawv cev ci ntsa iab muaj cov khoom siv organic, uas yuav cuam tshuam qhov kev sib tw. |
| Tin Plating Stress Residue | tensile kev nyuaj siab | compressive internal kev nyuaj siab |
| Plating nqi | kim dua | pheej yig dua |
| Organic Sediment Cov ntsiab lus | txog 0.015 feem pua | txog 0.015 feem pua |
| Qhov txawv txav | Qhov saum npoo yog npub thiab matt. | Qhov saum npoo yog ci thiab zoo nkauj. Nws yog ib qho yooj yim kom tig daj tom qab reflow soldering. |
| Kub Resistance | Kub kub tsis kam tom qab vuam | Tsis zoo kub tsis kam. Nyob rau hauv cov nqe lus ntawm qhov chaw, muaj lub caij nyoog ntawm theem nrab melting ntawm tin. |
| Kev thov dav dav | Terminals rau vuam, xws li fuse tooj liab hau, fuse hu, thiab lwm yam. | Terminals uas xav tau kev pom, zoo li txias-nias terminals. |
