Specification for Electroless Nickel/Immersion Gold (ENIG) Plating for Printed Circuit Boards Amendment 2 to IPC-4552 is a new section in the original release of the IPC-4552. The Amendment 2 provides the “rules” by which any rework and/or repair of a printed board's ENIG surface finish is allowed. Effective September 2012.

The Amendment 1 to IPC-4556 made the following changes to the base specification: a) It added the absolute value of the maximum thickness for the immersion gold of 0.070 μm [2.8 μin] that accompanies the statistically valid minimum immersion gold thickness; b) It added two more photomicrograph images to provide better information on identifying nickel hyper corrosion; c) It added the basis of...

本规范规定了使用化学镍/钯/浸金（ENEPIG）作为印制板表面处理的要求。本规范规定了ENEPIG应用于焊接、金属线键合和接触面涂覆层的沉积厚度规格。本规范适用于化学药水供应商、印制板制造商、电子制造服务业（EMS）和原始设备制造商（OEM）。ENEPIG是沉积在以铜为基底金属上的一个三层的表面处理。它是一种多功能的表面处理，适用于焊接和金、铝和铜金属线键合。它也适合作为软薄膜和钢凸圆接触的配合表面。其它应用包括使用低插入力（LIF）和零插入力（ZIF）板边连接器和压入式应用。化学钯层形成的扩散阻挡层，阻碍镍扩散到金表面。浸金防止钯层在加工前与污染物反应，否则可能会影响连接制程，如金属线键合和焊接。全文共82页，2013年发布。2018年10月翻译。

IPC-4554，印制板浸锡规范，包含在IPC-455X系列规范里。455X系列规范规定了取代印制板非共面处理（经常被称为锡-铅热风整平处理）的表面处理的要求。该规范是一个全彩色文档，适用于供应商或印制板制造商，电镀化学供应商，合同制造商或EMS工厂和原始设备制造商（OEM）。浸锡是一种通过化学置换反应，直接将金属沉积于印制板金属基材-铜表面的处理方式。浸锡主要作为可焊表面使用，目前也已使用在压入式连接及零插入力（ZIF）连接器的界面上。浸锡可以保护其下面的铜面在保存期限内不被氧化，符合IPC/ EIA J-STD-003规定的第3类涂覆层耐久性要求（贮存期大于6个月）。插入的修订本1是关于浸锡可焊性的更详细说明，使用锡铅和无铅焊料以及适当的助焊剂。

This document details the test procedures, test results and team conclusions for the IPC Cleaning and Cleanliness Testing Program, Phase 3, Low Solids Flux in Ambient Air. This effort has been part of a multi-stage program to investigate material and process alternatives to the use of chlorofluorocarbons (CFCs) in electronics manufacturing.

This Technical Report details the investigations into identifying stress tests that distinguish between robust and non-robust surface finishes. A robust finish will pass a test for solderability whereas a non-robust finish will fail. The stress tests identified do not necessarily duplicate real world environment (fabrication of the bare printed board through assembly), but they must correlate to...

The A-53-Gerber is a single-sided test board having six SIR test patterns which were designed for surface insulation testing. The test patterns consist of two comb patterns with 500µm (0.0197”) lines/spaces, two comb patterns with 318µm (0.0125”) lines/spaces and two comb patterns with 200µm (0.0079) lines/spaces. The contact fingers of the board are normally gold plated for compatibility with...

IPC-4552A 性能规范设定了对化学镀镍/沉金 (ENIG) 沉积厚度的要求，这些应用包括焊接、引线键合和作为接触表面处理。 IPC-4552A 旨在供化学品供应商、印制板制造商、电子制造服务 (EMS) 和原始设备制造商 (OEM) 使用。 除了 IPC-6010-FAM 印制板性能规范中的要求外，IPC-4552A 标准还可用于指定验收标准以满足性能要求。 使用本文件指定的 ENIG 沉积物将满足 J-STD-003 印制板可焊性规范中指定的最高涂层耐久性等级。 IPC-4552A 规范基于三个关键因素： ENIG 电镀工艺受到控制，产生镍和金沉积厚度的正态分布。 用于测量沉积物并因此控制过程的工具对于指定的厚度范围是准确和可重复的。 ENIG 电镀工艺可实现均匀的沉积特性。 如果不满足这三个关键因素中的任何一个，则生产的沉积物将不符合定义的性能标准。
