I looking for a possible rework on component terminals that are not soldering in a wave solder machine. The terminals (leads) are very oxidated.

ACI offers solderability restoration services by using Reduced Oxide Soldering Activation (ROSA) technology to remove the oxide layers from circuit boards or components and then re-tin or otherwise coat them to maintain a solderable surface. The R

You need to remove the oxide before you can properly solder your [or any] component. Call your flux supplier ask them for a more active flux than you are using and for their recommendations on removing the flux residues.

Cristiano, Are your oxidised components now all on boards ? How many and how many terminations ? If you have any that are still to be used, maybe you can get the supplier / customer to replace them, unless of course they are well old. If you have

Would suggest you have a re-look at your reflow profile. There could possibly be a higher thermal demand to solder the Pb-free version of these screw terminals considering that external plating has changed.

We know nothing about your: * Solder alloy * Materials of your board * Materials of your teminal block * Process setup of your wave * Wetting condition of the board or the terminal block ... but we'll take a guess anyhow. Tin-copper based solder all

Hi, Just as DaveF said; please give us some more information. It could be a a´lot of things. For .ex. Do you by any chances solder with Ni/Au at the board?

I have been working on Pb-free assemblies of screw terminals (terminal blocks). Unlike, other pin-in-paste conducive components, these component has square headed leads. We have been facing issues with the solder dripping into the oven. We were able

It is strange that you're having issues while using the same process parameters (including stencil) that worked successfully before. It doesn't guarantee that it's not one of those parameters changing in a manner that's not apparent, but it does sugg

| I have a product using high temperature solder to connect terminal pins to a PCB. The board is single sided copper, no plaiting. The solder is 95% tin 5 % silver. The flux is low activity rosin. The product is a subassembly. When the product i
