Increased demands on reliability result in the implementation of more stringent requirements

5G and Creep Corrosion - Does it Matter? The short answer is, yes. But, as always, it's never that simple or devastating. First off, what is Creep Corrosion? It’s the growth of copper sulfide crystals on a PCB surface that can create an electrical short.

The inherent nature of almost all immersion silver formulas did little to control the chemical reaction resulting in an aggressive attack of the copper. The consequence was field failures due to creep corrosion, champagne voids in soldering, and complete opens due to etching through of traces. To completely eliminate these issues requires a wholesale change of the formulation.

Introduction

With 5G rollouts around the globe, ENIG continues to hold on to first place in PCB final finishes. You would think with data published on how electroless nickel increases insertion loss, ENIG use would be declining. But there are a few reasons why the prophesized demise of ENIG has been premature.

Making thin electroless nickel deposits work. When the thickness of any protective coating is reduced, two issues, porosity and chemical resistance, must be addressed. By looking at the whole picture, 1 micron of electroless nickel can provide the protection & low insertion loss required for 5G success today and into the future.

In the vast field of decorative electroplating solutions, color treatments are distinguished by their use aimed at coloring and, at the same time, protecting metal surfaces in decorative applications. These product lines typically include special additives and coatings to increase the protection and durability of metal surfaces, while renewing their aesthetics by enhancing glossiness and exclusivity of the final products, depending on specific applications.

I Vantaggi della Nichelatura senza Acido Borico

La nichelatura ha una grande varietà di applicazioni nel settore della galvanica. Il nichel è utilizzato nell'elettroformatura, nei PCB e in quasi tutti i componenti elettronici, sia come strato intermedio, che come finitura finale.

I trattamenti galvanici decorativi, come ad esempio le metallocromie, consistono in processi per la colorazione e la protezione delle superfici metalliche nelle applicazioni decorative. Queste linee di prodotti generalmente includono additivi e rivestimenti speciali per aumentare la protezione e la durata nel tempo delle superfici metalliche, e al tempo stesso, rinnovarne l’estetica donando lucentezza ed esclusività ai prodotti, a seconda delle specifiche applicazioni.
