Indium got back to me with the attached PDF. I always assumed, that in order to avoid thermal shock, there could not be any more than 80 degrees C difference between the solder pot and the pre-heated board. However, it would seem that any thing le

Morning all. So today I have been tasked with conformally coating a few of our first run PCBs for a new product line. The problem is that they have already had all the larger caps potted with RTV. Are there any problems with spraying the CC over the

Wow RealChunks! What happened to that firey b#tchey Asian temper of yours? :-) Speak your mind and forever hold your peace! Here's what I know about Lead-Free Wave Soldering: 1.) Hotter pot 2.) Longer dwells Good info. on fluxes, by the way.

Questions are: * Does the component take solder when you dip it in the solder pot to test the solderability of the leads? * Can you get full barrel fill when wave soldering a bare board? * Is your flux reaching the top of the board through the hole b

We understand the problem of trying to coat over RTV. We have seen the same problem with acrylic and urethane coatings not wanting to stick to RTV. Some acrylics seem to be worse than urethane. Since this is a new product, may be you could pot your

Relays huh? I can tell you from previous experience that relays are not a good heat gun candidate. Did you check how long this part can withstand the 240? I do not know what the 4 setting is on a liester but it is probably well in excess of the 24

This is one of the biggest mistakes with the Lead Free process. We have all listened to the 'industry experts' and followed their advice and unfortunately got it wrong. Keep the dwell times (dependant on alloy selection) the same as Leaded so you are
