USING CONDUCTIVE EPOXY: Epoxies do not bond well to tin or tin alloy surfaces. * For components: a silver-palladium or gold end termination is recommended. * For substrates: gold over nickel should work well. Remember epoxy is not hermetic, and ox

Thanks Dave, From what I remember a lot of components went away from Silver Palladium to "base metal" terminations because of the difficulties in continuation of supply & stability of price. (Something about being mined in Chechnia or the Congo?) W

Hi, The ROHS compliant parts are usually Matte Tin on the outer terminal plating. There are also 2 further types of metal on the average chip cap - the undercoat metal of the outer electrode & the inner electrode. These are usually the same & are

We are experiencing some difficulties with reflow soldering a 1210-sized MOV with silver/palladium finish. The PCB finish is SAC. When inspecting the board after reflow it seems that nearly all solder is gone both from the pads and the component term

We are facing low quality due to soldering opens with coilcraft inductors 0402CS-2N7XGLW. The termination used is(suffix L =RoHS compliant silver-palladium-platinum-glass frit. Did anyone had this problem in the past? Can we do better using T = RoH

| Yes, norm it is. Look back to February 98 :discussion on this issue. Norm, That discussion does deal with palladium coated leads, but when I read your statement about silver/palladium fired terminations, I'm assuming that you're referring to

hi, 1206 capacitor with silver/palladium termination is mounted onto a ceramics substrates. Bonding is achieved through conductive epoxy. We discovered that the epoxy cracked and this caused missing capacitor. We had tried different grade of epoxy,

We have run not AgPd [that we know of]. We can comment on PdNi. [But you're probably have Ni under the AgPd] In general, palladium solution rate is much slower than other sacrificial finish materials that we use for the purpose. The key then is to

Responding to your questions ... RELIABILITY OF 1% SILVER SOLDER PASTE: It�s as good as the next solder paste, all other things the same. Look at your back articles by Jennie Hang in SMT magazine. I want to say she wrote an article on the topic i
