It could be from your Deionized Mixed Beds. Resin on the mixed beds can have that smell if its bad or not flushed prior to use. Its a fishy/rotten eggs odor It would still happen if you dumped the water but didn't swap out the tanks and would smell

Normally if the package is defined properly I would expect your machine to place it correctly but we have some parts pushed right down to the pads. If the paste is centered, and the parts are centered, and you have obvious bridging potential coming

Anyone using a No-clean solder paste on a pcb with a 100 Mbps Ethernet chip? Will the residue cause any signal degradation? Any issues with a no-clean solder paste and 1000 Mbps Gigabit Ethernet? Device: National Semiconductor DP83848 10/100 Mb

How do you normally solder it?

I need a good chuck, new or used, for a QUAD 100 pick and place. The chuck size is 00-001XG. The one I have has worn fingers, bushings, and leaks air around the nozzle. How difficult are these to rebuild properly? I would appreciate hearing from a

A water soluble solder paste (AIM WS483), reflow and wash. We are considering using AIM NC254 No-clean solder paste to eliminate the wash step.

I would think if the product can take wash, it could take no-clean. Unless it has sensitive devices susceptible to leakage.

We built tens of thousands of boards with transeivers on them with a no clean process.Never had any problems with the flux residue in relationship to board performance.

Oooo, nice machine. For chuck repair, try: Mt Sterling Industries POBox 670 Mt Sterling KY 40353 606.498.1015fax4156. This is not rocket science. A local machine shop could probably do just as nice of a job. For newer chucks, try the brokers list

Residues from different no-clean fluxes produce different levels of variation in RF circuits. Some no-clean fluxes work fine. Following this, a no-clean flux can produce different levels of variation in RF circuits depending on the process setup.
