spray gun for flux

I created a spray fluxer for our wave solder years ago that is still working well although does consume a lot of flux and is also rather messy. It's cheap and easy though so what the heck, right? I just machined a manifold that will hold four BETE

Crystalline flux if it is really clear should not be a problem. We were using Amtech paste before and we have the same results. Sometimes we mistakenly see it as a dry joint because of the reflections from the lighting of our Metcal inspection system

Wave flux and profiling

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

no-clean flux vs. impedance

The low solids flux that is commonly called no-clean can affect some circuits. We are building a PCB that measures pico amps. The customer required that it be cleaned. We would rather used the low solids and eliminate a step. The customer had

I have a customer that is having a flux residue problem after wave soldering. Flux is roaring through the board to the top side and leaving a residue. This is only happening on the flat stamped leads. The round leads are fine. They are using Supe

VOC free flux

I have heard that a drwaback to VOC free flux in the wave solder machine is the machine will rust. Is this guy for real? What do you know about drawbacks vs. benefits of VOC free? Thanks

No clean flux residue

Our PCBs manufactured with no clean flux have a waxy film on the board...is this normal? Our contract manufacturer recently switched to no clean from water wash. Thanks Carl

Hello Yannick, Have you brought this concern up with your supplier? I would recommend speaking with your flux and paste provider to gain additional insight and recommendations for resolving the concern. Good luck, Sean D.

voc free flux

What do you guys do with your old, used VOC free flux? Can you just send it down the drain? Or is it considered hazardous, and should be disposed of accordingly? Thanks for your replies.
