Electroless mean autocatalytic. Autocatalytic plating baths contain reducing agents ready to react with the substrate. The catalyst is the metal to be deposited. The reaction is completed when hydrogen is released by the reducing agent. A common reducing agent is sodium hypophosphite. Oxidation occurs and the result is a negative charge on the surface of the substrate.
1946 by Brenner and Riddell (United States).
Electroless plating is well suited for parts with complex geometries and/or many fine features. Electroless plating is generally more time consuming than electrolytic plating. The price difference is minimal.
Electroless plated finishes are very common and widespread in many industries. INTA Technologies is ISO 9001:2000 certified and we provide CoC’s as standard practice. Before parts are plated they are inspected and logged. After a rigorous cleaning and plating process the parts are again inspected. XRF equipment is used to verify the coating thickness in most cases. Random samples are chosen and the data is reviewed by staff and stored for future reference. Copies of the XRF data analysis and report are available with shipments. Be sure to request the data when sending an RFQ or PO. We use very strict workmanship standards and reject parts at final inspection for discoloration, bubbles, poor adhesion, scratches or other reasons depending on the exact customer requirements and specifications.
Most materials can be electrolessly plated. Some types of electroless plating methods are not well suited to specific substrates due to temperature and other restraints. Send information regarding your application to contact@intatech.com for feedback.
Yes.
Eless gold is not an
INTA Technologies specialty. It is a
special order item best suited for large volume.
INTA offers several varieties of electroless nickel. The most popular include:
Nickel boron
Nickel phos – mid
Nickel phos – high
Nickel Teflon
INTA does not offer Nickel cad (a.k.a. nickel cadmium).
Our specialties are nickel and copper.
A typical minimum coating thickness would be approx .00001-.00002” for electroless nickel or copper. If there is no electrolytic top coat it is recommended to build above the minimum, at least .0001” or greater for improved appearance and other features.
Average tolerances vary according to customer specifications. In general, tolerances range from +/- 15u” and up. +/- 100u” is preferred.
Electroless plating provides a very uniform coating, especially in comparison to electrolytic plating.
Non-uniform distribution forming a dog bone shape with thicker coating deposits at either end and a less thick coating in the center. Dog boning is not an important issue for electroless plating but can pose challenges for electrolytic plating projects.
Yes.
Electroless nickel immersion gold. It is a popular coating/surface finish.
INTA has a local and well-respected partner which offers ENIG. For information or a referral contact B.Kneedler, Manufacturing Engineer 408-748-9955 x113
Neither. INTA has a mix of small, medium and high volume orders.
Approx. 12-18” in length or width.
No, but we can give a referral.
