Dave, our facility does only military and aeorspace contracts, we still use only tin/lead solder and 186 Rosin Flux, so this info is just what I need. Thanks for your imput.

I have always been under the impression that you want the flux make-up of your cored wire and supplemental flux (squeeze bottle) to be as identical/compatible as possible. I was just looking over a manufacturers datasheet for a resin-based cored wir

We just got new boards in that have ENIG pads. In the past we had a problem with too much gold getting into the wave solder pot from large connectors getting tinned at the wave. Do we have to worry about too much gold getting into the pot with this

The soldering handbook that I use gives a 'rule of thumb' for best preheat temps for wave soldering. For multilayer brds that are metal core it suggests 110 to 130 degrees C topside temp to get the best solder fillet. We do a lot of multilayer meta

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

I got an inquiry from one of our electronics labs with regards to their soldering processes. They use eutectic (63% Sn, 37% Pb) solder. For liquid flux they are currently using Kester 186, which is an old-school, full rosin (RMA and ROL1) flux that c

Thanks Patrick, also IPC-HDBK-001 explains even better then IPC-J-STD-004, but unfortunately not yet infos about flux for L-F soldering.That's why I am trying to get some infos more from experienced people. Some L-F (SAC or SACX) cored wires vendor

A solder wire classified as L0 under IPC J-STD-004 means that the flux residues can be left on the board safely, and when you select this type of cored wire the intention is not to clean. You just select a solder wire that gives you an acceptable lev

I'm trying to find a solution that will clean our PCBAs that will meet the following criteria: 1. Low cost 2. Enable us to clean 25 - 100 PCBAs per day 3. Leave boards clean, including residue removal 4. Preferably environmental friendly 5. should b

| We have recently had problems with bare boards coming in too thick. I would like to know how to properly specify the minimum and maximum thickness using the 13949F and IPC 4101 specs. (We currently use "MATERIAL: GFN 0620 C1/C1 A2A per MIL - P - 13
