Check the tant cap for outgassing, tant caps are notorious for breaking wind and moving parts. Try baking the caps.

I have problem finding the values of two caps that are surface mount. There ID's are: One cap has a code of 1A5 the other cap has 225 16g 408 (yellow with a stripe) Thanks

Looks like the gurus in the smt department went out of their way to give ma another challenge. Their putting down these big taintalum caps. Some are pretty big, but I always thought taint caps can't take wave solder very well. Anyone have the same

I guess it depends on the size of the cap. I find that shadowing of other parts is the problem with Tant-caps. Tell the Gurus to stop picking on your Mom.

If everything else is OK, capacitors quality could be the cause of this issue. Some caps could have been contaminated or the metal mass not even between two ends. Try different kind (manufacturer)of cap.

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?

I'm sorry. These are SMT caps such as a C0805C271J1GAC. Small 0805 caps. I know they gennerally give you solder balls that sit on the side of those parts but they wash off.

I'm with Steve and flying probing. As long as you are testing the capacitance of the cap in the circuit and not of the cap itself you'll get a pretty good indication. Most are going to be 10nf and 100nf decoupling caps at that size so quite easy to

It's always safer to use a higher voltage cap than a lower voltage cap. It isn't a fuse... There is only one case where we dropped the voltage on a cap. We were using a tantalum cap that was rated to 16V, but had been built in the standard packagi

Hi. there's no other way to do except hand solder the top side cap or using hand print hand place method during SMT process. otherwise you will have to spend more time just to set up this process. bottom line is you have to install this one cap first
