FINISH PLATING
| TIN: |
Tin plating is a ductile, non-toxic metal generally used to improve corrosion resistance and maintain
solderability of the base metal. |
| |
|
|
| |
Matte Acid Tin (RoHS compliant) |
| |
|
Whitish/grey matte surface appearance. Softer than bright tin. Larger grain size and lower internal stress than bright tin. 99.98+ percent Tin. Compatible with lead-free and leaded solders. Better solderability than bright tin. Rougher surface finish and higher coefficient of friction than bright tin. |
| |
|
|
| |
Bright Acid Tin (RoHS compliant) |
| |
|
Shiny/bright surface appearance. Harder than matte tin. Smaller grain size and relatively higher internal stress deposit than matte tin. 99.8+ percent Tin. Compatible with lead-free and leaded solders. Smoother surface finish and lower coefficient of friction than matte tin. |
| |
|
|
| |
Specifications: ASTM B545 Type I (Electrodeposited), MIL-T-10727 |
| |
|
|
| TIN/LEAD: |
Low melting temperature and good flow characteristics make this finish popular for
solderability. Resists whisker formation. Tin/Lead finishes are NOT RoHS-compliant. |
| |
|
|
| |
Matte Tin/Lead |
| |
|
Available in a variety of alloy ratios. |
| |
|
|
| |
Specifications: ASTM B579, MIL-P-81728 |
| |
|
|
| NICKEL: |
Used to provide a decorative, wear resistant, corrosion resistant and anti-tarnishing
surface with high temperature resistance. |
| |
|
|
| |
Matte (Ductile) Nickel |
| |
|
Compliant with ASTM B689 Type 1 bath requirements. Provides a highly ductile deposit. |
| |
|
|
| |
Bright Nickel |
| |
|
Compliant with ASTM B689 Type 2 bath requirements. Provides a harder, reflective nickel surface. |
| |
|
|
| |
Specifications: ASTM B689, QQ-N-290 |
| |
|
|
| COPPER: |
A ductile metal used as a decorative finish or to provide improved conductivity. |
| |
|
|
| |
Matte Copper |
| |
|
Our standard copper under-plate can also be applied as a finish plate. An anti-tarnish agent is applied to inhibit corrosion. |
| |
|
|
| |
Specifications: ASTM B734, MIL-C-14550 |
| |
|
|
UNDER-PLATING
| COPPER: |
| |
Applied under tin plating or nickel to improve ductility and adhesion of finish plating during
part formation. Required to inhibit zinc migration (diffusion barrier) per ASTM B545 on
certain alloys. |
| |
|
| NICKEL (SULFAMATE): |
| |
An optional solution for tin plating or nickel plating to inhibit zinc migration (diffusion barrier) per
ASTM B545. Can also be used to reduce stresses in tin plating (believed to play an
important role in whisker formation) caused by the formation of the inter-metallic bond
with copper alloys. |
| |
|
| NICKEL (WOODS FLASH): |
| |
Used as a preparatory layer to provide adhesion to stainless steel
and nickel-bearing alloys. |
| |
