Yes l know this problem keeps cropping up on the forum but l've missed some of the follow-ups. Our problem is that the lifting only occurs on 3% of production so actually detecting an improvement is difficult. We're actually having to inspect

Jacqueline, Asuming you mean immersion silver: Advantages - Very flat finish compared to HASL, more easily solderable than bare copper with OSP and more process tolerant than this in our experience, reasonable shelf life, cheaper than immersion gol

The Effects of PCB Fabrication on High-Frequency Electrical Performance

Technical Library | 2016-07-21 18:16:06.0

Achieving optimum high-frequency printed-circuit-board (PCB) performance is not simply a matter of specifying the best possible PCB material, but can be significantly impacted by PCB fabrication practices. In addition to appropriate circuit materials and circuit design configurations to meet target performance goals, a number of PCB material-related issues can affect final performance, including the use of soldermask, the PCB copper plating thickness, the conductor trapezoidal effect, and plating finish; understanding the effects of these material issues can help when fabricating high-frequency circuits for the best possible electrical performance.
