Q1. Can I do this myself on site? A1. Sure. Most companies demoisturate their components in-house. Q2. Can we use our Vitronics Soltec XPM820 Reflow Oven? A2. You can. Most of us would be using an oven like that in our product processing. If you look

I have a problem with placement repeatability and accuracy on this Samtec connector. The customer wants to use a "nubbed connector" which has to be placed in the corresponding PCB holes. When the nubs miss the holes, the part becomes "lifted." SEE

If at all possible buy parts with 3% min. lead on the terminations. If this is not an option, "mitigate" whatever the finish is. Typically this means tinning with 63/37 all the exposed lead, not just the solder joint area. Several companies can d

Anyone have an 'easy' solution for reducing PCBA handling damage. I'm fighting low level chipped, scuffed and broken-off SMT parts. The damage is spread out across different areas of the assemblies. The assemblies are double sided SMT with 0402's

We've used our standard chipbonder- Heraeus PD944- for this type of application. While it does cure before reflow, when the part is placed onto the site, the material compresses and spreads and thus that potential standoff isn't an issue. We've als

Just a comment, we have been using the OEE as metric in our plant, what I've seen is that can be misunderstood because a good OEE level does not mean a good machine utilization, let me try to explain this on my own words. I have a HMLV line, so when

Is this a single head Quad IVc or a dual headed line? if it is a dual line you can swap the align cards in the front bay between the two heads and see if the symptom follows. The card on the far right is a transport card, shouldn't need to swap tha

Good afternoon all, I have been trying to find a solution to a defect I just noticed. After stencil printing and smt part placement on the secondary side of my boards, I run them through a wave soldering system. All my components got soldered perfe
