> the dirty patch appear seems to be a bit powdery on top of stickiness > the "harden" dirt in the solder pot or at pump are ususally "knock" out while cleaning.. is that thorough enough..? Assuming that 1) is true it might not be thorough enough. On

Hi, I tried to use high temperature solder (540 - 570F)to connect four spacers on the board. The solder mask around the spacers wrinkled a lot.I can even see a few bulbs around it. I use hot plate and solder rings. After hot plate is heated to appr

I gleen from your post that this assembly is mixed technology. You may have a compatibility problem between the flux in your wave solder machine and the flux in your solder paste. Check with the manufacturer of each and see if they interact. | I ha

So, there is a crack or gap between: * Solder and component termination. Bingo Correct? Describe: * Coarseness / smoothness of the metal on the termination underneither the crack. * Solder left on the termination. Unfortunately at 45X I can't rea

While the only way this thread could look more like a stealth advert is if it has the word 'advertisement' blinking at us, I'll play along. Questions are: * Have you asked the supplier Fantron Technologies [sales@fantron.com] what they suggest? * Wh

I'm sure this isn't the same situation, but we did have a selective solder machine with crazy dross and solder ball build up. Turns out the operator switched the low pressure nitrogen line used for solder level and the high pressure nitrogen line fo

You will need to preheat the boards for a lead free selective solder process. A preheat module is critical for any wave or selective solder process, if you don't get the board preheated properly the solder is going to resist flowing to the top of the

Indium Corp. has some, 3549-HF and 3590-T, both are OK for foaming. Most of the better performing newer fluxes require spray application for best performance. Alpha, Kester and others have wave fluxes too. http://www.indium.com/products/circuitboar
