You are very right. There are 2 major factors 1) There is going to be Flux separation. This is basically due to fact that metal particles are heavier than the Flux vehicle system, and due to gravity effect they slowly drift downwards leaving the ligh

First, it's not a simple as thinking just about your electric meter. * Water heaters need to be DI proof, stainless or ceramic. * The longer that DI water is exposed to air, then closer it becomes like tap water. So, you need to be monitoring DI leve

The backflow in the wave started to become very important with the development of no-clean/no residue fluxes. These fluxes don’t have (or at least shouldn’t have) rosin, resin or other vehicles in the formulation which encapsulate surface oxides from

Yes well, now we used to add a bit of flux to our leaded paste to make it slightly runny, But when we went to unleaded paste the joker who came in from another company to set the temperature on the oven said "you dont add anything to unleaded paste!.

If no-clean flux is reflowed correctly, many of the activators are encapsulated within the resin residue left behind after reflow. An ionic contamination test cannot differentiate between ionic residue that was encapsulated (not harmful) and residues

That's what I guessed. Some ideas to consider are: Reduce usage of flux to the bare minimum. Choose a low solids flux Flux residues can be categorized as soft, brittle, sticky but this depends mostly on the formulation of the flux and the resins

Good Morning, I'm a relatively new engineer, and i've been experiencing a lot of anomalies when it comes to our inline wash. We have an Austin American Hydrojet, and no matter how many times i clean the tank, it still foams like crazy! its been happe

| I am looking for the Industry standards on vias. Are they required to be plated with solder or is copper plating enough? What about reliabilty with either one? Also, if tenting the via is required should it be copper plated or solder plated over
