Immersion Silver PCB Manufacturing
With the pending lead-free legislation impacting PCB manufacturing on a global scale, the immersion silver process is rapidly gaining popularity as the lead-free surface finish of choice.
Immersion Silver is the standard finish on PCB Train and is ROHS compliant. It is an improvement on HASL being exceptionally flat, and can replace immersion silver over Electronless Nickel (Au/Ni) for most applications. The use of Immersion Silver has no effect on customer's assembly processes. Immersion Silver Metallic Solder ability Preservative is a 0.1 to 0.2 micron layer of metallic silver coated with an organic layer of solder ability preservative.

Costs and Quotation of Immersion Silver PCB Manufacturing
The total costs of immersion silver PCB manufacturing and assembly services are mainly determined by PCB dimension, laminate thickness, surface finish, layer(s), other special technical requirements (such as blind & buried via, impedance), components, numbers of soldering pads and test plan. You can send PCB files (Gerbers) and BOM to get instant quotation within 24 hours.
NOD Electronics also offers PCB assembly service for our PCB customers. We will quote you in a short time, we will guarantee all components is original, we will follow your BOM list to purchase components, also our PCBA prices are competitive like our PCBs. All your jobs can be done under one roof, SMT, Thru-hole or Hybrid!
