Radial capacitor placement

Electronics Forum | Fri Jun 18 11:43:38 EDT 2010 | davef

With proper lead forming, a radial capacitor (1000uf, 25V) can be placed flush to the board. If you place it as you describe, does your product application environment require staking?

United Chemi-Con makes a 2200uF 35V capacitor EMVA350GDA222MMN0S That's the biggest SMT capacitor I have ever encountered. Jerry

Blow Holes voids in solder fillet on caps

Electronics Forum | Tue Jun 26 15:40:12 EDT 2012 | ssupertuba

Hello there, I'm presently experiencing some blow holes and solder voids in the solder fillet of caps on boards. They are ceramic caps. The solder is SAC105 and the parts range from 33pf to 0.1uf ceramic. Any suggestions?

Does anyone have experience with LOCTITE ECCOBOND Underfill?

I will try outline Theta and Z-axis servo issues, we were facing last time. Story behind. Our 750 is used seldom and last time after switching it on initialization procedure ends with T axis of right head: Servo alarm. Opening front cover of 750 two

SMT Design Issues for 2225 Capacitors in High Power RF

Electronics Forum | Mon Aug 08 16:14:36 EDT 2011 | wmburke

We are building a plasma diagnostic to monitor MHD phenomena in tokamak. As part of the development, we need high-voltage, high-power RF capacitors to tune and match an inductive load. This application is similar to a small induction heater, with t

Advice for a newbie, please: Can an existing PSB be adapted to slow it down? Maybe add a resistor?

Electronics Forum | Mon Aug 10 16:53:26 EDT 2015 | rgduval

If the pendulum is motor driven, it's more likely that a capacitor change will accomplish what you want than a resistor change. You've got a 47uF in there...try a factor of 10, and put a 4.7uF in there and see what happens. If the pendulum period i
