Listen, you should try to utilize wave solder as well. High speed gadgets are fine if you want to make things complictded, but if your just starting things up, think simple. Nothing beats wave for solder many parts at the same time. If you can't p

In reviewing the JEDEC 95 guidelines (2002) there is not a mention of tolerances that have been agreed upon for today's finer pitch devices. There was no mention of the solder diameter tolerances (low melt temp) allowed for 0.8mm, 0.6mm and 0.5mm pit

Howdy Marc, Check with your flux vendor, they should have a data sheet with what you need. Baring a wave rider or other profiler, I use a laser thermometer (They're cheap.)and It gets me close to where I need to be on our assemblies. I usually chec

I'm based in the UK and need a new thermally protective case for my SlimKIC. We are running lead-free now and I'm concerned about the extra heat damaging my SlimKIC. I've been quoted �525 for a stainless steel Lead-free compatible case (KIC-1001), wh

All data loggers will be warmer at the higher lead free temps. Only two ways around this... better thermal barriers or fans after the profile to cool it down. Some places do not allow fans on the production floor due to static electricity, in that
