Application Examples
CT-3S Dipping type seal treatment agent for (Ni/)Au



PA-2 Adhesion promoter

Merits of CT-3S to be employed
- To inhibit corrosion of pinholes on Au(Ni)-film and improve reliability of contacts.
- To reduce thickness of Au film and save the cost of Au-plating.

・Salt Spray Test Results: 96h
Substrates:C1020P/Ni (2µm)/Au (0.05µm)
Test Condition:JIS Z 2371
Features of CT-3S
- To achieve excellent corrosion resistance with shorter treatment time compared to conventional CT-3
- Not to influence contact resistance and other properties with its monomolecular coating characteristics.
- To be soluble in water and not to include any organic solvents and heavy metals.

Merits of PA-2 to be employed
- To improver adhesion strength between resin and Cu, Fe-Ni alloy, Ag, Pd, and Au.

・Effect of Adhesion Strength between resin and metals
Features of PA-2
- Our uniquely developed silane-coupling agent to uniformly absorbs onto metal surfaces.
- The functional group of the Our silane-coupling agent to accelerate hardening of resin.
- To provide copper and copper alloys with corrosion resistance.

FAQ
What are the selling points of CT-3S?
-
Continuously wet-treating the plated product gives the plating film a corrosion-resistant effect.
It is a water-soluble surface treatment chemical.
How do I use CT-3S?
-
This product is diluted at the specified dilution ratio and immersed at the specified temperature and pH. After treatment, it is washed with water and dried.
How is CT-3S different from other products and conventional products?
-
Three points of appeal for CT-3S:
- ①Improved corrosion resistance: processing can be performed in a shorter time than conventional products, and corrosion resistance is improved (salt spray, nitric acid aeration, etc.).
- ②Monomolecular adsorption film: keeps contact resistance value low and does not affect soldering characteristics.
- ③Water-based sealing agent: treatment of effluent is easy because it does not contain organic solvents that cause environmental pollution. No need for explosion-proof equipment leads to safe working environments.
What is the introduction record of CT-3S?
-
It is a development product.
What kind of product is PA-2?
-
PA-2 is a water-soluble surface treatment chemical that improves the adhesion between precious metal surfaces and epoxy resin by continuously (R to R) wet-treating precious metal-plated items.
How is PA-2 different from other products and conventional products?
-
Three points of appeal for PA-2:
- ①Originally-developed silane coupling agent: adhesion improver between resin (epoxy) and precious metal.
- ②Monomolecular adsorption film: does not affect assembly characteristics of solder or interfere with the original characteristics of metal.
- ③Water-based sealing agent: no need for explosion-proof equipment leads to safe working environments.
What is the introduction record and market share of PA-2?
-
It is used by LF manufacturers. Chinese LF manufacturers have performed final surface treatment, and it has demonstrated effectiveness in improving adhesion with sealing resin after assembly.
How is PA-2 used?
-
This product is diluted at the specified dilution ratio and immersed at the specified temperature and pH. After treatment, it is washed with water and dried.
