In general, the commercial protective agents can be roughly classified into physical and chemical methods on plate layer by producing a protective skin. The protective skin, so called metal sealer, is commonly carried out by using the physical method, and various kinds of plating layer can be protected, simultaneously.
These serve six purposes:
1. to increase corrosion resistance of plate layer
2. to retard oxidation and stable the resistance as electrical contact
3. to lubricate metals and reduce corroding
4. to enhance and maintain solderability
5. Cost down of precious metals
6. to enhance the success rate of plate rework
| Product Name | Description | Features |
|---|---|---|
| SCA | The organic matter with strong hydrophobicity fills the pores on the surface of the coating and forms an organic film that can insulate air. |
|
| ST-1 | It is a mixture of oily organic solvents and an additive for SCA sealing agent. | |
| SCW | Water-based sealing agent is suitable for electroplating layer sealing, anti-corrosion, moisture-proof, anti-oxidation, stable electrical resistance, promote soldering, lubrication and other chemicals with multiple functions. |
