We have an electrovert 16" econopak wave solder machine with two identical pots (exchange between Tin Lead and Lead Free). When the pots are exchanged the same thermocouple is used, and the same controller is used - with the set point adjusted. The S

Hi Matt, Get definitive answers! Contamination on the HASL finish?: From the pix you posted, it looks like something fishy is going on. I�d reject them back to the board house and demand an answer. Most board houses and purchasing people will g

EricR: Regarding "*** By the way, since we have used the Tin-Silver-Copper lead free solder there has been a strange liquid type chemical leek from the oven exhausted pipes." ... I don't know anything about your process, but the first thing I'd inve

For selective soldering I would first look at the alloys your products require. Do you run tin-lead, lead free or both? If you run (or may run in the future) two alloys, then look for a machine that has quick change solder pots. Secondly, do your bo

I'm involved in backplane manufacturing process. There are about 10 electrolitic capacitor assembled in my board.These capacitor are soldered using a selective soldering machine. My problem is that these capacitor will charged up and failed as short

Notes from an AIM No-Lead Presentation ... Wave Soldering * May require a higher pot temperature than tin/lead: 255-265*C * May require a change in liquid fluxes to compensate for the poor wetting of some alloys and high thermal stresses of the wave

I disagree about the maintenance issues with tin/copper solder. All high tin content solders are hard on machines (silver or not). More dross? Controlling the back flow, front flow velocity and AVOID constant surface cleaning will reduce your dros
