Melplate SN-2680
Melplate SN-2680 is neutral-type electrolytic tin plating solution for electronic parts.
◆Features
1. Little attacks on ceramic materials or low-melting glass because pH is neutral.
2. Good solderability.
3. Very few tin whiskers.
4. No generation of Sn(IV) precipitation.
5. Control coupling of product and aggregation of media.
6. Flow-Through Plater is available due to low foaming.

Chip compornents
Melplate SN-2680 forms excellent tin deposits, which is necessary to assemble of chip components to PCB.
Assembled MLCC on PCB
Melplate SN-2680 deposits have good solderabiliy.
Thermal shock test
This table shows the result of thermal shock test. Whiskers was generated from conventional pure tin film. And Sn-Pb film also caused small changes. While the film from Melplate SN-2680 was no change. SN-2680 can prevent to generate whiskers.
