Tant Cap fell down after SMT

Electronics Forum | Thu Apr 07 10:33:23 EDT 2011 | markhoch

The Part Data sheet should specify whether or not the part can withstand the Wave Solder. (I've wave soldered many Tant Caps)It sounds like you need a higher volume of SMD Adhesive. How are you applying the adhesive?

Thanks for your suggestion however it looks like AVX may be the only vendor who can supply such a cap in a 0805 package. TDK cannot do anything below 1206 or so i'm being told

Hello, When we discover the broken caps, there are missing and we can observe only either the 2 terminaisons or a small part of ceramic. The defect is due to a shock during the process but it's possible that the caps are fragilized during an operati

I am trying to program some tant caps on my universal 4785 chipshooter and it just won't take. If anyone has any experience with the 4785 please let me know. I have programmed some pretty tough parts in the past and I know the vision on the 4785 c

I have some files from the 1980's that I need to convert to Gerber. Some contain ASCII and some don't. There is a reference to Personal CAD Systems, Inc., PC-CAPS and PC-CARDS. Can anyone convert this or tell me if software is available to do it?

SMT Electrolytic Shorting

Electronics Forum | Mon Jul 30 16:34:45 EDT 2007 | John S.

We're seeing shorting from the lead of an electrolytic cap to the can. It appears to be solder wicking up the lead, through the boot, and then shorting to the can. Has anyone else experienced this? It is a very cheap cap from China of course, but

Cracks on ceramic capacitors.

if the capacitors are placed very near to the edge and their position is 90 deg than it may cause crack.4thly if the reflow ramp rate is more than 3 deg C then it may crack. 5th ly if the solderin tip temp. is very high and soldering bit is very thi

Degassing - the air in the void above the electrolyte expands, or in some cases the electrolyte vapourises, blowing the top of the cap from the base. Sometimes electrolyte can also leak out around the base seal. This is also a failure as the cap wo

Components randomly wiped out in reflow

hello Diego, I would start by opening oven and looking for missing components. once you locate them you can work from there. are you using any alu caps on your board? I had problem with bad alu caps exploding in oven and scattering other components.

In same board both leaded and lead-free components used.

Hi Imtiaz, Can you give a brakup of the 23 components and their end mettalurgy ? Chip ?? QFP/TSOP ?? BGA ?? Aluminium Caps ?? this will determine whether you can do it or not
