I'm with Steve. Check the datasheet, and make sure that the terminations are meant for solder application, and not conductive epoxy. I had that happen a year or so ago with an MLCC. Drove us nuts for two days (not to mention the significant rework

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

Hi, I'd be inclined to go with the through hole capacitor, as to surface mount it you would probably need to go for an elco (ceramics & films don't do that value in that voltage, & you'd be hard pressed to get a tant in that voltage). SMD Elcos a

Hello everyone, I am working on a very low cost, small and basic vending machine ($300) with wooden cabinet for small neighborhood stores. As you may know, it is necessary to properly protect the components to prevent users from trying to steal money

Let me just shortly explain why do I open this thread. In my corporation in different plants we use same components at the same machines in different products(Fuji machines). I would like to create kind of global database of shapes ( its in FujiFlexa

Rob, We are also using intrusive reflow to simultaneously process SMT and Thru-hole components. Our arrangement goes as follows: - Screen print solder paste to the single sided PCB using 0.008" laser cut stencil. - Apply adhesive dots to selected

I need to install two SMD chips (0805) at one location. I refered to IPC-HDBK-001, fIG 6-24. When I solder the chips side by side, the ceramic side which is placed againgst solder pad- is already touching the solder. While I complete the solder joint

Maybe there's no test and I don't know where or why my customer came with that requirement (I think because in one of the board shipments he got a board were a smd resistor broke, but I think that happened because miss handling), but anyway I need so
