Hi All, I am using COB on my DOUBLE SIDED PCB. lastly we used Eletrolytic Ni / Flash Gold Plating. Our Boards vias Failed the UL corrosion Test. we did some cross-section analysis and found 10.75 �m of Nickel and 0.022 um of Gold and as the Process

Dave, We are using Kester Easy Profile 256 No clean Sn62Pb36Ag02. The oven itself is a Dima SMRO-0252 which is a short oven, it has 13" of preheat, 13.5" of soak, 6.25" of reflow, and 10" of cooling on the way out of the oven. We are soldering multi

Jim: Several points: 1 If you�re correct about corrosion of your component leads (which is entirely possible if the leads are steel, as you say), then the AIM 264-5 no-clean may not be aggressive enough to remove the corrosion you are seeing routin

Guys, I have been down this road also spent a lot of time working on this. Electrolytics often are difficult to solder like this. For the sake of testing, try a water soluble more active flux as an initial test. IF you compare hand solder wetting the

I've never seen this before. Today, I got this tombstoning on Tantalum Capacitors (Okay, I saw that before) Here's the part that seems weird to me: -They didn't tombstone onto a termination - they went onto their sides! That's right, both terminati

I agree with Steve...most certainly a placement occurance. I've seen this on many occasions with Panasonic equip. Change your feeder first and then check your component packaging. | I've never seen this before. Today, I got this tombstoning on Tan

I have a strange issue where all 4 spindles of head 1 on my GSM1 are able to place small parts without a problem until the very end of the routine where a large electrolytic aluminum capacitor is placed. The part is successfully picked out of the fee
