suggestions on how to dissipate heat on a snap-in capacitor that''s NOT soldered …
I just read that capacitors needs produces heat and this heat needs to be dissipated. When installed in a PCB, this is not a problem as the copper traces can act as a PCB. I want to do a simple unregulated power supply using point-to-point (think tube wiring).
Decoupling capacitors
Hello, I am making a circuit but i did some research and found out that i should use a 100uF electrolytic capacitor in parallel with a 100nF ceramic capacitor to smooth out the DC voltage, by connecting both capacitors between VCC and GND. But before i build it, i want to ask if it''s OK to just solder the pins together before i place these …

Important not to spread aluminum capacitor legs at the body?
I''ve been using it since July and the PC is fine, however, I''ve just noticed that one of the capacitor leads is bent/soldered at an angle compared to other, nearby capacitors. I assume this particular solder joint was touched up manually during QC at the manufacturing plant and this is why the solder looks less then ideal - based on …

How to remove capacitors that are glued down?
Many times on the power supply section of a device I will encounter a pair of large capacitors soldered to the board AND glued to the component side board. The leads are often on the thick side and bent at a sharp 90 degree angle as the leads exit the solder side of the board. Anyhow, with...
Pin-in-Paste Soldering for Through-Hole Pins
Although pin-in-paste soldering is an option for mixed technology PCBs, that does not mean wave soldering is not useful, including when producing at volume. For example, when a board has a certain configuration or placement of the SMD parts, wave soldering can still be used to assemble the through-hole parts.
