Solderability Problem on NiPdAu

Electronics Forum | Sun Sep 12 12:45:56 EDT 2010 | tony1

Hi there, does anyone experience in NiPdAu solderability dip & look test? I experiencing solder non wet issue on side I/O & also center ground for QFN package. Appreciate someone can offer me a solution. Thanks

NiPdAu Soldering Problems?

Electronics Forum | Thu Sep 18 23:56:56 EDT 2008 | trynders

am having wetting issues with two Burr Brown Op amps. Both are SOICs with NiPdAu lead frame finishes. I have attached a photo that shows a black streak the length of the lead (before soldering). This appearance is consistent of all leads and is exist

Nordson MARCH Research Evaluates the Effects of RF Plasma Processing Prior to Conformal Coating on Adhesion, Conformity of Coverage, and Electrical Functionality

Industry News | 2016-03-03 08:27:28.0

Nordson MARCH has recently released a white paper showing the results of RF plasma processing on conformal coating adhesion, the conformity of the coating coverage, and the resulting effects on electrical functionality of a fully assembled printed circuit board. The research was done in conjunction with Nordson ASYMTEK, AirBorn Electronics, and SMART Microsystems (formerly known as Desich SMART Center). The paper can be downloaded at

Evaluating the Effects of Plasma Treatment prior to Conformal Coating on Electronic Assemblies to Enhance Conformity of Coverage

Technical Library | 2017-06-01 17:12:08.0

The corrosion of Nickel-Palladium-Gold (Ni-Pd-Au) finish terminals in humid environments is known to be reduced with the application of a conformal coating such as acrylic. Corrosion has a higher rate of occurrence around the terminal ‘knee’ of a surface mount component, which may be reduced with the application of conformal coatings. Although radio frequency (RF) plasma processing is generally known to enhance conformity of conformal coating to surfaces through ionic bombardment, the effect on the functionality of assembled printed circuit boards (PCB) is not as well known. The purpose of this study is to assess whether RF plasma processing can enhance the adhesive and coverage qualities of an acrylic conformal coating on PCBs, specifically on Ni-Pd-Au terminals with a knee, and if plasma processing has an effect on the electrical functionality of components and fully assembled PCB.

Effects Of Storage Environments On The Solderability Of Nickel Palladium- Gold Finish With Pb-Based And Pb- Free Solders

Technical Library | 2022-03-02 21:26:51.0

The solderability of a nickel-palladium-gold (Ni-Pd-Au) finish on a Cu substrate was evaluated for the Pb-free solder, 95.5Sn-3.9Ag-0.6 Cu (wt.%, abbreviated Sn-Ag-Cu) and the eutectic 63Sn-37 Pb (Sn-Pb) alloy. The solder temperature was 245ºC. The flux was a rosin-based mildly activated (RMA) solution. The Ni-Pd-Au finish was tested in the as-fabricated condition as well as after exposure to one of the following accelerated storage (shelf life) regiments: (1) 33.6, 67.2, or 336 hours in the Battelle Class 2 flowing gas environment or (2) 5, 16, or 24 hours of steam aging (88ºC, 90%RH).
