Hot Solder Plating

hot solder plating

Hot solder plating, also known as solder dip, tin plating, tin dipping and tin spinning, is one of numerous services offered by American Micro Industries.

The hot solder plating process makes ferrous and non-ferrous materials more resistant to corrosion and wear.

Hot solder plating extends the life of the material by protecting it from oxidation. The process generally creates a coating of 0.1 to 0.3 mils (0.0001 to 0.0003 inch) thick.

We offer traditional 60/40 Tin / Lead (Sn/Pb) plating. This type of plating yields a Bright finish for your non-EU and sanctioned EU applications. These exemptions include military and medical device products.

American Micro Industries is able to provide plating to comply with military specifications.

What are the Benefits of Hot Solder Plating?

Hot tin dip solder plating offers a number of advantages for both manufacturers and end users. Notable benefits of this process include:

  • Efficiency: Hot soldering is the only plating process that offers 100% anode efficiency and 100% cathode efficiency. When a soldering process uses a current more efficiently, less power is wasted and results in lower operating costs. Complete anode and cathode efficiency makes hot plate soldering one of the most cost-effective options for a number of different applications.
  • Durability: The coating formed by hot dip soldering is highly resistant to corrosion, oxidation and other forms of wear and tear that occur over time. It is also non-porous, which means it offers superior protection against pollution and other harmful substances. Hot dip tin solder plating is harder than the coating formed by electroplating, and offers higher abrasion strength, as well.
  • Quality: Hot solder plating is more ductile and provides better surface characteristics than other processes. Hot soldered coatings are solid and homogenous, highly stable and stress-free. Hot solder dipping is also the best way to avoid tin whiskers, which can cause shorts and arcing in electronic components.
  • Ease of application: Applying a hot solder coating to a component is fast and economical. Tin solder has a lower melting point (370°F/188°C) than other materials, which means it can be applied without the use of expensive, highly specialized equipment. It also penetrates holes and coats the inside of walls easily, which improves quality control.
  • Regulatory compliance: Hot solder dipping is a requirement of certain components under a number of military and civilian standards. American Micro Industries can provide hot solder plating to ASTM-B32, QQ-S-571, MIL-F-14072 M258, MIL-F-14072 M221 and several other relevant standards — call our office directly for more information.

To meet the needs of demanding clients manufacturing these and other products, American Micro Industries complies with all of the military, federal and ASTM specifications listed below. Call us if you have any questions.

Though the materials in the following chart are not all inclusive regarding our hot solder plate capabilities, they are the ones with which we have the most experience.

Some materials such as brass require an electro-less nickel under plate prior to hot solder plating. This under plate prevents the zinc migration of the base metal from contaminating the plated surface.
