Capacitor discharge resistance welding is ideal for projection, press-fit and annular ring projections up to 4.5″ in diameter. Low marking welds can be better achieved due to the small heat affected zone and dissimilar metals that can often not be welded using conventional resistance welding can be successfully welded using capacitive discharge …
Soldering SMD electrolytic capacitors
The solder mask between the pads keep the solder from flowing between them. If you don''t mind wasting some solder wick, you can prove this on your own boards. Remove the capacitor and then heat the bare pad and start flooding it with molden solder. It will bead up on top of the pad, but will not flow across the solder mask to the adjacent …

Soldering capacitor pins
It sounds like you are talking about component orientation, not literally the order of soldering the wires. In this case, yes for some capacitors it is important which way around they go. The negative lead is identified with …
Capacitor Discharge Stud Welding | Welding, Brazing, and Soldering …
Capacitor discharge (CD) stud welding is a stud arc welding process in which the tip of the stud melts almost instantly when energy stored in capacitors is discharged through it. This article describes the three basic modes of the CD stud welding: initial-gap welding, initial-contact welding, and drawn-arc welding.

Capacitor Terminations and Soldering Recommendations
- soldering time must be very quick (a couple of seconds). NB: multilayer ceramic capacitor attachments with a soldering iron are discouraged due to the process control limitations. IV.4. Flux Flux applied to surfaces that are to be joined by soldering. The flux cleans the surfaces, prevents oxidation during soldering and results in a better bond.

soldering
Capacitors (and semiconductors) should have such a soldering cycle specified in the datasheet. The temp spec -40 to +85 refers to continuous use in the end application. The capacitance within this temperature range may vary as specified by the dielectric temperature curve (X5R, NP0 etc) and tolerance (+/-10% etc).

Replacing Capacitors With Different Values Guide
Once the new capacitor is ready, heat up your soldering iron and carefully remove the old capacitor from the board. If it''s a through-hole component, simply desolder each of its leads separately. If it is a surface-mount component, heat up the solder pads and use tweezers to gently pull it away from the board.
