We wish to use rectangular 4 segment solar panels in our quartz watches & charge the battery. The size of the soalr panel is 18.20mm X 7 mm and the thickness is 1.15mm. The other popular application of this type solar panels is in calculators. These

Thank you Dave, that is almost the asnswers we use to give to our Customers when auditing they ask for component shelf life. But as you can imagine, they whant to see a quick information right on the label (on Reels, on trays, etc) like: Use b

We're not real clear about what you're trying to discuss, because most capacitors are packaged in epoxy with a solderable termination on each end. But lets throw a couple of ideas at the wall and see what sticks. If this epoxy is: * From the capaci

Sounds like the Pin in Paste would be a reflow technique not involving a pot. I'm guessing however the same causes are in play, in that the poorer wetting of the Pb-free allow means it drops out of the joint before it can wet to the terminal. We us

I observed some black dot or some oxidation occured on chip termination on pcba reflowed fews weeks ago as buffer stock. The solder joint and fillet wetting is good and shinning. It is an acceptable or defect condition per IPC standard/requirement? W

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.

Hi, Appreciate someone could advise or forward a format to me how to work out number of pallet needed for wave-solder if the machine speed is at 1.0m/min, volume per month is 4500 sets, pallet length 0.3 meter, conveyor length 5 meter...... Looking

| 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

Shy, What is your current method of applying adhesive? If the terminals of the component that has adhesive are not wetting ( or not forming a solder joint I think we are talking about ) after reflow, then you must be applying too much adhesive. As

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
