The 483 is what we use on all boards except on one where the 353 improved wetting on resistor packs. It worked much better since the parts are LF and this is the same flux AIM uses in their LF solder. Yes, it was recommended by AIM when we discussed

We have a board that uses 0402x4 RNET packages that we are having a difficult time getting to solder consistently. Paste deposition is fine (using AIM WS353) and profile is dead-nuts. I'm starting to wonder if this is something that we're just goin

We are also having some issues with certain small parts. In our case this is tantalum caps and 0402 caps. We had a vendor admit after much discussion that the plating used from a particular orgin was different on the tantalums. The tehory is thatthsi

Grant, Newer lead-free fluxes have 6%-10% solids content - more activator, therefore leave more "visible" residues. Old technology tin-lead fluxes got down to as low as around the 4%-6% range (I'm going off memory, so me might be wrong)... You'll

We use SN100C for wave soldering and hand Lead free soldering and have had very good results. The wire cored solder for hand soldering flows good and makes very good solder joints. The SN100C in the wave solder machine also works very good. We use

NO-LEAD COMPONENTS WITH LEAD SOLDER ISSUE: We agree with Russ. We've dicussed this several times on SMTnet. For instance, look here http://www.smtnet.com/forums/Index.cfm?CFApp=1&Message_ID=25394 LEAD COMPONENTS WITH NO-LEAD SOLDER ISSUE: We disa

You�re a good man Rob and a good patriot, you defend your governments decisions even if they're wrong. Isn't the WEEE directive aimed at preventing electronics ending up in a landfill? This immediately takes away the leaching arguments and is a great

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.

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
