Excellent wetting for both lead-free (SAC305) and leaded (Sn63Pb37) alloys.

Acts as an intermediate barrier that prevents nickel from oxidizing or corroding during the gold immersion process—a defect known as "black pad". Immersion Gold (IG):

Before the release of IPC-4556, designers and fabricators often struggled with vague specifications. Standard PCB tolerances do not apply when you are etching copper that is 10 oz or 20 oz thick. ipc4556 pdf

The Evolution of IPC-4556: Elevating Reliability in PCB Surface Finishing standard, titled the

The device went on to become a huge success, and Emma's team was hailed as pioneers in their field. And Emma herself? She became known as the go-to expert on all things IPC4556 – a testament to the power of perseverance and attention to detail.

The IPC-4556 standard explicitly mandates that layer thickness be measured using X-Ray Fluorescence (XRF) methodology . During the standard's development, IPC used XRF extensively, establishing a detailed set of measurement criteria. XRF is the only IPC-approved non-destructive technique for this purpose. Key considerations for accurate XRF measurement include: Standard PCB tolerances do not apply when you

Because of its high reliability and cost-efficiency relative to thick pure-gold finishes, ENEPIG boards compliant with IPC-4556 are standard across several high-consequence industries:

The core function of the document is to provide standardized requirements that ensure ENEPIG performs reliably across various assembly technologies.
